Stair treads are prefabricated grating panels designed specifically for stair installations. Manufactured from welded, press-locked, or swage-locked grating, they combine high load-bearing capacity with excellent drainage and ventilation. Standard treads are supplied with nosing plates and side mounting plates for quick and secure installation.
Available in carbon steel, stainless steel, and aluminum, stair treads can be customized with plain or serrated bearing bars, various bar spacings, and multiple finishes to suit indoor and outdoor applications.
There are totally 4 models of stair treads according to the differences of front fenders and installation methods.
Stair tread is made of the steel grating that is widely used in different kinds of structural steel stairs and it’s of convenient installation and maintenance, firmness and beauty without logged water. The dimension of stair tread can be designated by the buyer’s requirement.
