Grating item 15903 – Specifications

Grating article 15903 is a composite/fiberglass stair tread with a fine mesh 19×19 mm pattern and 38 mm height, specially designed for safe use on stairs. The surface has finely divided silica sand in gray (RAL 7001), which provides good slip resistance even in wet or oily environments.

With a finer mesh width than the standard step (15902), this variant is particularly suitable where smaller openings are desired, for example for use with heels or where smaller objects should not fall through.

The step has reinforced edges on both sides with a yellow front edge (RAL 1003), which provides clear visual marking of the step edge and reduces the risk of missteps. The reinforced edges also withstand the extra wear and tear that stair edges are normally exposed to.

The step has isophthalic polyester as its raw material, and therefore achieves fire class 1 (ASTM E84-05) with a flame spread below 25. It has insulating electrical properties and can withstand temperatures from -20 to +80 °C.

We deliver the step in a plate size of 573 x 3658 mm, with a maximum recommended length of 1 meter per step. Please contact us and we will help you choose the right solution for your project.
