Pressed platform gratings KWO are steel components that can be used as openwork fillings in any kind of structures. They are used in construction and industrial sectors as work platforms, walkways, entrance scrapers, canal covers, driveways or components of storage racks. Moreover, functional features of platform gratings are often used by architects as facades, barriers, shields or suspended ceilings.
Our product are made of load bearing and cross bars. By connecting the two, we get a stable and precise structure capable of carrying distributed (continuous) or concentrated loads. The use of such forms minimises the unladen weight of bearing panels and reduces the load on supporting structures. By properly the dimensions of flat bars and selecting the spacing of flat bars, we provide for the optimised use of our products, thus eliminating unnecessary material consumption and excessive costs of production.

PRESSED GRATING - CHARACTERISTIC
Our platform gratings are manufactured on fully computerised and automated production lines. The machines we use have dedicated control systems, and ensure top quality, precision, repeatability and precision of workmanship of final products along with minimum costs of production. Moreover, ensuring high manufacturing precision, we are able to meet technical specifications required by our customers.
Structural components of KWO product are load bearing bars and cross bars. The connecting procedure involves pressing a cross bar under great pressure (up to 2,000 kN) into a specially notched flat bearing bar. This process creates a permanent press locked connection that keeps a specific spacing between the bars (the mesh).
Load bearing bars are designed to wear loads on platform gratings during their use, while cross bars give the lattice their grid form, and join and position bearing bars with respect to one another.
The length of a load bearing bar should coincide with the span between the beams of the supporting structure, provided that the backrest width on a supporting beam is equal to the grating height, and not lower than 30 mm. The load bearing dimension is traditionally marked as "L" and called the grating length. The second dimension is width "B" which is the length of a cross bar.
Our standard pressed gratings are framed with a flat edging bar with the same thickness and height as the load bearing bar, but to meet our customers' needs, we also make frames of other profiles (angle and U-bars, and hollow profiles, etc.); and the gratings can be also manufactured with no edging.
Distance between load bearing and cross bar is the mesh size of a grating. The mesh size of our pressed gratings ranges usually from 11.1 mm to 99.9 mm (11.1 mm panel).
Our pressed platform grating is made in accordance with DIN 24537 standard, tolerances indicated in RAL-GZ 638 instructions and technical specifications for their manufacturing. Overall dimensions of panels are made with negative tolerances from 0 to -4 mm (note: at the design stage, the spacing between gratings should be assumed to be 0).
Our products are manufactured of S235JR grade steel as per EN 1002. At the final stage of production, our gratings are hot-dip galvanised in compliance with ISO EN 1461.
We encourage our clients to request our recommendations to ensure proper selection of platform gratings.
