Steel grating with weather resistance performance and solid structure is widely used in chemical, petroleum, sewage treatment plants and other fields for stair treads, platform and walkway applications. You can refer to the product page of stair tread steel grating to know more bout the gratings.
A bar grating stair tread is a series of bearing bars joined to perpendicular cross bars at various intervals to form a load-bearing panel designed for use as a step. Stair treads are manufactured with defined visible nosings and pre-punched end carrier plates or angles, ready for bolting to stair stringers. The nosing, which protrudes slightly over the edge, increases safety by providing additional space for users’ feet.
