Stair treads are structural elements of a building that allow communication between levels. In heavily used areas, metal stair treads with a cheeky structure are most commonly used. In most cases, they are supported by a wall on one side and a beam on the other, or both sides are supported by beams. Metal stair treads are manufactured from gratings and are commonly referred to as treps. Let's find out what is worth knowing about them?

Metal stair treads for special tasks

Metal stair treads are used wherever pedestrian traffic is intense. The cheeky design of the stair treads makes them resistant to considerable loads. The material is also important for their functionality. Steel gives the components made of it exceptional strength. Metal stair treads are durable and resistant to mechanical damage and abrasion. In the galvanised version, they also do not succumb to negative atmospheric influences and are not at risk of corrosion. In addition, they are very easy to keep clean and do not require any maintenance. Metal stair treads can be successfully used both indoors and outdoors. They ensure the highest safety standards, especially thanks to the use of perforated anti-slip strips. They are characterised by low weight and simple installation. They are reliable, versatile and highly aesthetic designs.

Different variants of metal stair treads

Metal stair treads are used for the construction of walkways with a straight or rounded layout, medium-length stairs and short entrances of several steps. They are ideal for arrangement with other grating constructions. Their construction must comply with DIN 24537. They are used as entrance stairs for cellars, warehouses, production halls, attics, car ducts, stages or stadiums. They work well in industrial buildings and public facilities. The dimensions of the grommets and flat bars from which the steps are formed can be adapted to individual customer expectations. Metal stair treads are filled with WEMA or KOZ type gratings, but are also available in the following versions serraton. Openwork staircases made of expanded metal with a diamond mesh stand out for their exceptional adhesion to footwear in all conditions. Rectangular meshes, on the other hand, are made of welded or pressed grating. An alternative infill for metal staircases is solid corrugated sheet metal. Metal stair treads are equipped with fixing holes on the bottom or side.

Platform gratings are small steel structures that are manufactured from load-bearing flat bars, which carry the load, and bars (or flat bars), which bind them together. The rapidly developing manufacturing technology of gratings makes them widely used in a variety of architectural solutions. They are most often used to create walkways and bridges in industrial buildings. They are characterised by optimum lightness, strength and aesthetics.

Characteristics and classification of gratings

Platform gratings are usually manufactured from black steel, stainless steel, acid-resistant steel or coated with anti-corrosion coatings usually by hot-dip galvanising. They are characterised by high corrosion and chemical resistance, do not succumb to the negative effects of UV radiation and have a wide temperature operating range. They require no additional protective coatings, are easy to clean and have good thermal and electrical properties. They are highly resistant to rust and chemicals. The supporting flat bars used in gratings can be smooth or serrated (serrated). The serrated flats give the steel gratings anti-slip properties. Serrated gratings have an increased coefficient of friction. Floor gratings are durable, robust and resistant to heavy loads. They can be successfully used in high-traffic areas. Their design is modular and easy to install.

Due to the specifics of the manufacturing process, a distinction is made between welded or pressed gratings. A welded truss is constructed of support flat bars, which are connected by a transverse bar fused into the structure. The transverse bars are connected to the supporting flat bars by resistance welding. In contrast, a pressed (push-in) truss is formed by pressing a transverse bar into a supporting flat bar. Within both groups, additional functional types can be distinguished, such as gratings offshore whether in the type security mesh with compacted mesh.

Application of gratings

Platform gratings are widely used in industrial construction, shipbuilding and warehouse management. They are used as communication and service platforms, staircase landings and stair treads. They are used as elements of ramps, ramps and working platforms and reinforce floor and façade structures. They can be used to make storage racks, partition walls and machine enclosures. However, gratings are not only used in industry and construction. They are also widely used in public spaces. They are used to create ramps for prams and wheelchairs and doormats in public buildings. They can be used to harden the ground, build segmental fences or stages for outdoor events, and as a covering for duct openings. Platform gratings are also increasingly used in a decorative function, as a tool for arranging residential interiors.
