grid stair treads also call step is a kind of steel grating used for platform stairs. According to the installation method, there are generally two types: welded and screwed. The side panels of the grip strut stairs that are directly welded to the keel do not need to be added.
It is more economical and durable, but not easy to disassemble. The bolted steel bar grating stair treads needs thickened side panels on both sides. Drill holes in the side panels. The installation is directly fixed with bolts and can be recycled and reused. Customers can customize according to their actual needs.
