It is increasingly evident that urbanization processes significantly reduce the infiltration capacity of city soil during rainfall events. This inevitably results in the migration of various substances from the place where they are deposited to the entrance into the drainage system: a phenomenon known as wash off.

Among the elements that make up the urban drainage system there are crowning and closing devices. The UNI EN 124:2015 standard defines:
• crowning device the upper part of a collection well composed of a frame and grate with or without cover;
• closing device the upper part of an inspection pit or inspection chamber composed of a frame and a cover and/or grid.
In this case, the gully gratings play the fundamental role of connecting the road surface and the sewer pipes, intercepting the rainwater that flows on the surface, but also that of closing manholes serving the electricity, telephone and road lines.
Based on their hydraulic role, the gully gratings are designed to significantly interfere with the rainwater runoff regime, counteract road erosion and avoid dynamic and viscous aquaplaning linked to the thickness of the water film on the roadway.

The structure of a building flooris is a result of an elaborate stratigraphy that depending on the material chosen and the type of floor on which it is laid.
The use of the terms subfloor, laying base and reinforced mesh as synonyms often misleads, because they are different parts of the stratigraphy.
In usual building practice, the subfloor is laid on top of the attic: a horizontal layer, approximately 10 cm thick, having the function of filling the cavity with the systems and compensating for thickness irregularities.
The reinforced mesh is subsequently laid as a support layer for the floors which has the purpose of resisting the various mechanical stresses imparted both by the flooring and by its operation, distributing the static and dynamic loads.
It is one of the components of the stratigraphy of the floor that must be studied with greater attention based on the type of floor and the physical and mechanical performance required, which is why it is said: "each floor has its own reinforced mesh".

Asphalt is a mixture of solid and semi-fluid hydrocarbons which is used to create the surface layers of road paving. It is mixed and placed hot on the surface of the road to make the road level safe and homogeneous.
The term "asphalt" is used incorrectly because the correct term is artificial bituminous conglomerate.
Instead, for operations on small surfaces, is used "cold asphalt"

The cover/grid system, frame and well form a single body used for specific functions which will have to withstand stresses and be accessible for inspections and maintenance. The installation of the frame on the well is therefore an operation of fundamental importance to guarantee the stability of the device.
Before proceeding with the installation, it is therefore essential to take into consideration both the materials used and the project, as well as the minimum time to be respected before restoring normal circulation to prevent premature subsidence of the bedding, with the consequent separation of the frame from the cockpit.

In the coming decades the cities will increasingly take on the character of a vast area, with the consequent increase in the built environment, the structural network, land use and the reduction of permeable and transpiring surfaces.
The city sewage infrastructure has to deal with problems that concern not only the outdoors (the capacity of deep and superficial infiltration, the volume of discharges, the management of green spaces, environmental pollution, etc.) but also indoors, due to those phenomena that the operators define as "the attacks of nature".

Galvanizing is the process by which a zinc coating is applied to a metal product, generally made of steel, in order to protect it from corrosion.
The galvanizing process can take place through different methodologies. Among the most used is hot dip galvanizing: an anticorrosive treatment that occurs by immersing the products in a bath of molten zinc, at about 450 ° C, after a series of pre-treatments.

Combined kerb and drainage units are fundamental elements of connection between the roadway and rainwater sewer pipes, designed to intercept and convey the rainwater (or road washing) that flows in the surface. They are installed on the roads, in correspondence with the sidewalk kerbs of streets, squares or parking lots, to prevent water from excessively accumulating on the surface, exposed to the meteoric event. In addition to this thanks to hinged covers, they allow cleaning and an easier access to underground rain collecting systems.

Chambers are very important in the rainwater management, in fact they stand as a fundamental part of the system. Moreover, the drain trap is an essential element of the gully/chamber system by conveying rainweater correctly, preventing bad smells coming out from the drains, avoiding in the same time clogging and whirpools. In most of the market available drain traps , however, rainwater and debris often create stagnation, becoming an environment issue for the proliferation of unpleasant insects such as tiger mosquitoes, cockroaches, drain flies, and several other insects and rodents, creating a real hygiene issue. These problems are often addressed with insecticides and chemicals that may accumulate, from time to time, in the aquifers and in the surrounding soils with a relapse toxicity problem to the environment.
As a possible solution against insect larvae, with particular focus on sustainability, Link proposes the innovative ECOSYSTEM: an intelligent tilting lever (open/close) mechanism.

The pannel for concrete floor and the substrate are two different layers present in the floors, as a horizontal structure that divides the different floors of a building. The intrados surface of the floor is called the ceiling, while the extrados surface is the support of the floor of the upper floor. The floor system rests on the extradosal surface, as a set of layers between the structural support and the final flooring: a system that requires careful planning to ensure resistance, stability and safety.

Urban and peri-urban locations are characterized by partially waterproofed areas due to extensive overbuilding. Although generally equipped with infrastructures dedicated to the collection, confinement and treatment of rainwater and runoff, these areas constitute very complex environments due to urban development and the strong increase in vehicular traffic.
The increased contamination of run-off water and the relative worsening of the qualitative characteristics of the receiving water bodies have now become one of the cornerstones of environmental protection policies and, more generally, of the quality of life in urbanized areas.

In physics the wheelbarrow is a second type lever which, consisting of a rigid body (lever) capable of rotating around a fixed point, fulcrum, (the axis of the wheel) does not carry energy, but moves towards an external position forces. In the second type lever, the transfer of energy is always advantageous because the power arm (the force we apply to lift the handles) is always longer than the resistance arm (the force we have to overcome - the load). It follows that the transport of a load through this type of lever is useful for those who have to carry weights.
Structurally, the wheelbarrows are formed by a container that receives the load, resting on a frame made of sheet metal, equipped with pedestals to support the wheelbarrow without it overturning and two handles, as an extension of the poles connected to the wheel axis. The poles form the frame of the wheelbarrow, and the supports for ground support are fixed on them.
Link offers a series of accessories studied to complete the building range, including wheelbarrow wheels, performing and safe because tested not only at the manufacturer, but also by national laboratories, designed to give completeness to the building range.

Manhole tops are used to close service shafts, water and sewers systems as well as electric, telephone and other services' lines. Similarly, the gully tops, instead of the lid, adopt a grid and are mainly used for the collection of rainwater.
The manhole tops and gully tops characteristics and performances are regulated by the UNI EN 124: 2015 standard. Although presently adopted in all EU countries this Standard is not yet harmonized since it has never been published on the EU Official Journal.

Urban spaces have experienced a great transformation in history following the historical and cultural changes of man, immediately perceptible in the architecture and plans of our cities.
Structural changes that have brought out the difficulty of calibrating this evolution with the needs of the community and its territorial identity, such as to trigger, in the architectural debate of the 21st century, strategies for recovering data spaces, putting hand to new "hooked" architectural elements to existing buildings. The search for new design solutions has led to architectural experiments such as parasitic architecture designed to transform urban space by taking something from existing buildings and inserting new elements.
Whether it is a question of hanging green spaces or urban en plein air constructions, galvanized grids and recessed access cover can offer their contribution in ectoparasitic architectural creations.

Renovating the house is a necessary process in the life of a property that is inevitably destined to age. The interventions can take place both on the building part and on the systems and can concern important redevelopment actions or simply be planned for a restyling of the interior of the house.
Beyond the extraordinary or ordinary maintenance interventions, even the simple decision to renovate the house, starting with a new paint job, requires targeted planning and the implementation of some precautions. In fact, painting is one of the simplest ways to bring aesthetic changes to the rooms of the house through an apparently simple operation that requires some precautions, such as: knowing the types of water-based paints, the characteristics of the surfaces, trying the chosen color, having the right amount (detergent, spatulas, sandpaper, putty, etc.) and protect the environment (floors, stupid, electrical sockets, baseboards and furniture).
The walls must be carefully prepared, brushed and often washed. If there are cracks and holes, it is necessary to scrape the damaged areas by removing the parts that tend to come off and fill the cracks. Similarly, in the event that there is upholstery to be removed, it is necessary to proceed with a deep wetting, or if there is mold, a specific treatment is essential. Works that involve a significant production of debris, powders and liquids that can compromise the success of the work.
For this reason, as a first precaution, it is essential to spread a specific cloth on the floor that protects it from fragments, from any stains and from frequent passages with work shoes.
Link Industries, offers its customers PFR-110/125/150: a professional, non-slip, absorbent, reusable cloth, hot coupled with PE film, 180g / sqm.
It is commonly called "Millefiori" for the colored dots of the recycled fabric that constitutes it, whose raw material is verified in accordance with the "REACH" regulation 1907/2006 / EC, to ensure constant monitoring of any risks of intrinsic chemical substances in the products marketed.
The application of a specific felt, instead of the common newspaper sheet or polyethylene sheets, offers a greater grip reducing the risk of slipping and, given the structure of the cloth coupled with the polyethylene film, holds liquids more easily avoiding the stains. The specific grammage performed protects the floors from accidental impacts, scratches and grooves due to the pressure of stairs or small scaffolding.
Correctly spread, up to covering the skirting board on which it can be fixed with relative paper tape for building works, it saves 1/4 of the time, minimizing the final phase of restoration and cleaning. It can also be used several times and used not only in building applications but also in removals as a packaging membrane, minimizing the investment.

We offer two main ranges both consisting of an aluminum structure, raw finish, PUSH & PULL closure and moisture resistant plasterboard:
ECO RAW RANGE - Consisting of angular fixings with self-tapping screws and door lock with steel fin
ECO PLUS RAW RANGE - Consisting of rivet fasteners and door lock with chain and EVO gaskets.
Link hatches are easy to install and their assembly usually involves 4 phases:
1) marking INTERNAL CONTOUR and engraving the shape and size of the hatch on the plasterboard panel
2) insertion of the hatch in the hole made in the plasterboard to position the external frame
3) fixing the hatch frame using suitable plasterboard screws
4) hatch door installation and closing

Frequently the atmospheric precipitations exceed the infiltration of water into the ground. In environments with non-waterproof surfaces such as woods and fields, the runoff phenomenon is poorly perceived because the meteorological waters are generally filtered into the ground. Instead, in urban environments, characterized by overbuilding, the surfaces are mostly impermeable and rainwater flows superficially in a motion often conditioned by depressions, pipes and channels. These runoff waters, if they are not managed correctly, can cause damage to the environment, because they are responsible for the leaching of particulates and heavy metals deposited on the asphalt. Devices for gully tops and manhole tops for vehicular and pedestrian areasand tanks for the drainage and containment of rainwater, wastewater or irrigation: these become the fundamental safeguards for the containment of this phenomenon.

The primary interest of each owner is that their investment is functional, efficient and advantageous. To obtain such a performance, plays a decisive role the performance of the building envelope that they must guarantee a wholesomeness of the indoor parts and the longevity of the systems. The technological evolution of the energy performance of the building envelope is expressed fully in the Passive House, whose energy demand for heating and cooling the internal environment is cleared of passive devices. An integral part of the passive architecture is the "Rendered facade", as a composite solution that provides for the application with gluing and / or mechanical fixing of insulating panels on the external side of the building envelope, finished superficially with a shaving cycle with reinforcement network. This solution, properly designed and correctly laid (both in new buildings and in renovations), becomes the main instrument to achieve correct thermal insulation by minimizing energy consumption, maximizing comfort, while increasing efficiency and durability of the system. investment and the real life of the structures with a low environmental impact.

Based on the European Standards (ETICS System), Paroc has developed a special panel, the LINIO 10, which meets the characteristics required for the single rock wool product for the cladding system and which meets all the requirements for the insulating panels contained in it. in the ETA (European Technical Assessment), obtained according to the ETAG004 Guidelines by the leading market systems.

To complete the passive insulation system of the building envelope, Link proposes glass fiber nets as reinforcing elements for the external glazing cycle of the cladding system, and for the insulating cover package it recommends a series of breathable and control membranes steamed for the correct migration of the water vapor flow from the inside to the outside of the building, also through the cover:

• nets fiber glass (reinforcing elements of the external shaving cycle of cladding systems) are a material that does not rust, is not attackable by biological agents, has no problems of aging or deterioration, and according to the type chosen, finds large use in buildings for reinforcement of the finishing shaving cycle in ETAG004 insulation systems, or as networks for thick plasters or nets for thin coatings of plasters.

• transpiring membranes (which provide a waterproof and airtight cover, resistant to loads) and vapor control  barriers (which regulate the flow of steam that migrates from the inside to the outside of the heated building, avoiding thermohygrometric situations critiques with formation of interstitial or superficial condensation in the covering stratigraphy, especially in winter periods).

The proposed solutions can be used to reinterpret "old methods" in an innovative way, reaching, with extreme ease of installation, the highest performances, solving at the same time the problems related to the recovery of the existing and / or the efficiency of the new one.

The future is the Passive House, informed to increase the efficiency and functionality of your home through a new green and sustainable approach.

The grid is a rectilinear group consisting of two plates contained by a border that is distinguished in:

• the supporting plate is the one with the largest dimension suitable for unloading weight on the edging;

• the connecting plate (or secondary) is the one that connects and unites the load-bearing plates, unloading the weight on them and making them solid.

The grid can be contained in a frame for the intended use, whose function is to interpose between the grid and the product on which it will be supported.

The different production process distinguishes the grids in three types:

• electro-welded - smooth and twisted connecting rounds sold welded to the bearings .;

• pressed - the connecting plates are interlocked by means of special grooves arranged mechanically by very high pressure;

• printed - the supporting plate, with a closed profile, is formed by punching a pre-galvanized steel sheet obtained through the cutting processes.

Link, thanks to its long experience in the sector, is able to develop a wide range of customizations, while a series of steel grids, pressed (with or without frame), hot-dip galvanized according to the UNI EN standard are always available in stock ISO 1461, standard mesh (33x33 mm) and light duty heel proof (33x11 mm) as a selection proposed by our technicians.

The range of sizes available, the various possibilities for customization, durability and a marked aesthetic taste make these products widely used in various applications. For more information please contact us.

In the world the availability of water is enormous, but only about 3% is represented by fresh water (ground and surface water) whose withdrawals increase progressively. In fact, the theme of a correct and efficient management of the water resource becomes a recurrent topic and in several sector studies: we can read that water is now considered a precious and increasingly "scarce" good. In the analysis of the asset-water, the reasoning on the water infrastructure that supports it and the consequent need for its efficiency, is fully part of it. The urban drainage system, made up as follows, consists of a complex network of pipes, mostly underground, installed to collect and dispose, away from civil and production settlements, rainwater or surface runoff and wastewater.

The meteoric runoff, cooling waters deriving from industrial activities, those for irrigation from gardens, parks and spring waters, are considered as white water. They flow into the sewers through urban drainage systems that intercept them while they flow, channeling them into the plumbing drainage system.

Link offers its customers a series of concave and flat grids, in cast iron, designed to collect and flow these waters. They are structured for the use of siphon, equipped with an innovative safety system with snap closure and compliant with EN124-1 / 2: 2015.

GSGEN grids:

- Group 3 - Class C250 starting from size 300x300 up to 700x700

- Group 4 - Class D400 starting from size 500x500 up to 700x700

Our drains have a system of constraint to the frame that uses rotation hinges, allowing the opening and, if necessary, the possible removal of the grids. They are also provided with elastic closing bars: a safety system that prevents accidental opening while allowing regular access for cleaning and maintenance of the collection facilities.

Our drains in class C250, in compliance with the Decree of the Ministry of Public Works, have loopholes with a width of less than mm. 20 for the safety of cycling traffic. The draining surface has been developed to be largely within the regulatory requirements and to favor the normal flow of water.
