Press locked Grating

The press locked grating is the most commonly used type of grating in many European countries today. Thanks to a production technology which differs significantly from that used for the press welded grating, and which enables a much greater variety of products, this type of grating provides for an almost unlimited number of applications. Its design allows for great flexibility regarding the mesh size and the height and thickness of the bearing bars. In combination with the variety of materials from which press locked grating can be manufactured, we produce grating that are exactly in line with the customer‘s wishes and the intended use. We do not claim that the press locked grating is the better grating, but it is certainly the more attractive and individually customised grating compared to the press welded grating.

For a press locked grating, the cross bars – which as a rule are made of cold-rolled flat steel – are pressed into the previously punched-out bearing bars. The banding bars are designed as T-shaped or flat sections, and are attached by means of automatic resistance welding. If there is an increased risk of slipping, press locked grating can be manufactured in an anti-skid design. For this, the bearing and/or cross bars are notched on the upper side. With press locked grating, the opposite end meshes are usually of equal size. But here, too, applies what has been said above: there is almost no limit to the imaginable uses and designs of press locked grating.

Press Welded Grating

MEISER press welded grating is traditionally used in many areas of industry. The continuous welding of each individual intersection point of the bearing bar and cross bar produces an extremely stable and hard-wearing structure. The cross bars normally used in the press welded grating are twisted square wires, which are resistance welded to the bearing bars.

This is carried out under high pressure using automatic resistance welding. Manufacture is carried out on production lines that have been developed by ourselves, where we can produce made-to-measure grating panels without waste and in accordance with our customer wishes. This is achieved by the fact that our machines can produce panels with cross bar lengths of up to 1,250 mm, whilst other more conventional machines are restricted to 1,000 mm. Utilising our larger panel widths can give savings of up to 20 % in the number of fixings required which obviously translates into bigger savings in installation time and labour costs. MEISER press welded grating is primarily used in the oil and gas industry, petro-chemical industry, mining industry and in power stations. Where strong shearing forces occur and platform flooring has to be changed frequently, the superiority of the press welded grating comes into its own. Steel fabricators also appreciate the press welded grating, whose stability is ideally suited to the subsequent working of materials. MEISER press welded grating panels are normally banded with flat sections and can be produced in V2A and V4A with round or ribbed cross bars. Upon request, for grating manufactured in mild steel, the cross bars can be supplied in the size 7 mm (twisted) or 8 mm (ribbed).

Stair Treads

MEISER stair treads are manufactured from grating incorporating endplates and non-slip safety nosing to their leading edge. The tread as an essential safety element of all types of staircases must always function correctly, be it during everyday intensive use on the access path to a ski lift, or where subjected to extreme loads, if, for example, the staircase is used in an uncontrolled manner as an escape route by many people during a fire.

MEISER is aware of this responsibility and has designed its stair treads accordingly. The extended, perforated safety nosing fulfils and even exceeds the latest regulations. It provides additional stability, reduces the maximum depth of the opening to 120 mm and fulfils safety class R11. At the request of the customer, the nosing can also be made of a special section, e.g. a non-slip steel flooring plate or a sanded steel angle.

The safety endplates have a pronounced bead, which interlocks with the bearing bars. This prevents the endplate from tearing off prematurely if it is subjected to significant excess loads and causing the tread to fail. The tread surface of the MEISER stair treads can be designed individually. As a matter of principle, stair treads can be produced as press locked grating treads and press welded grating treads. The mesh spacing and height of the bearing bar are determined by the effective width and the customer‘s requirements.

Of course we know what is required in the case of publicly accessible staircases. The stair treads are produced in accordance with the specifications of DIN 24531-1 and provide for a corresponding hole pattern in the endplates. Individual hole patterns are of course possible, as well as notched bearing bars and cross bars, so that slip resistance up to class R13 is possible. It goes without saying that stair treads can also be designed in aluminium and highgrade steel; special designs allow stair  tread widths of up to 4,000 mm.

Grating is a structural element that has a high load-bearing capacity with a low dead weight and a high level of transparency. The positive-fitting connection of the bearing bars and cross bars with the surround make the grating not only a very stable, but also visually attractive product. The applications are very diverse, as grating is used everywhere in industry and architecture. As an extremely robust, safe yet light platform flooring, the grating is indispensable in all areas of heavy industry.

Grating is installed in refineries, power stations, steel mills, mines and on oil platforms. Every steelworker, metalworker and fitter needs grating in his trade. Grating is being used increasingly more in the logistics industry as platform flooring and shelves. Architects and building owners appreciate the grating as a product which is both aesthetically pleasing and functional – be this as decorative facade cladding, a suspended ceiling or sun shield.

MEISER offers the largest range of grating worldwide. The diversity of possible applications also requires an unusually large variety of products. Together with our customers we select the right grating from our range. Grating is almost always relevant to safety, and we are well aware of this responsibility.

When one is standing high up on a „breezy“ platform made of MEISER grating, one understands the importance of quality and reliability. We set the highest standards for our products – from the planning stage to delivery.

MEISER grating is 100 % made by MEISER. More than 80 % of all grating are made to measure at our two factories in the Saarland and Vogtland for our customers. Our employees will be pleased to support and advise you with planning your projects. Static calculations and quantity surveys also form part of our scope of services.
