Stair Tread Grating

Stair Tread Grating

Stair tread grating is a robust metal grating specially manufactured to be used as stair treads and tread strips. Each tread is manufactured by welding together load-bearing flat steel bars and twisted cross bars to form a rigid, open, anti-slip tread surface. Stair tread grating provides safe support in the stairways of industrial plants, power stations, chemical facilities, warehouses, and infrastructure projects, and its open pattern allows water, oil, and debris to drain away instead of accumulating on the tread.

Product Overview

Stair tread grating is a robust metal grating specially manufactured for use as stair treads and stair step elements. Each tread is manufactured by welding together load-bearing steel flat bars and twisted cross bars to form a rigid, open, anti-slip tread surface. Stair tread grating ensures safe footing in the stairways of industrial plants, power plants, chemical facilities, warehouses and infrastructure projects, and its open structure allows water, oil and debris to drain away instead of accumulating on the tread.

Stair tread grating is available in four standard end configurations, T1, T2, T3 and T4, each designed for a different stair installation condition. The width, thickness and spacing of the flat bars, as well as the cross bar spacing, can all be customized to meet specific load requirements and stair dimensions, and treads can be supplied with or without nosing and side plates.

Heavy-duty steel grating

Heavy-duty steel grating is a high-load-bearing metal grating designed for the most demanding industrial and infrastructure applications. It is manufactured using thicker and wider load-bearing flat steel bars, with a thickness of 6mm or more and a width of 50mm or more, welded or pressure-locked with cross bars to form a rigid, one-piece structure. Heavy-duty steel grating is capable of supporting loads exceeding 10 tons, making it ideal for heavy traffic areas, large-span platforms, and critical structural flooring.

FRP Grating

FRP grating, also known as fiberglass reinforced plastic grating, is a high-strength, corrosion-resistant composite grating manufactured from glass fiber rovings and thermosetting resin. Unlike steel grating, FRP grating does not rust, does not conduct electricity, and is not affected by most chemicals, making it the preferred choice for chemically aggressive, humid, and electrically sensitive environments. It is widely used for walkways, platforms, stair treads, trench covers, and structural flooring in chemical plants, water treatment facilities, marine environments, and food processing plants.

Trench cover

Trench cover grating is a heavy-duty metal grating specifically designed to cover drainage trenches, cable channels, and service ducts while supporting pedestrian and vehicular traffic. Each cover is manufactured by welding load-bearing flat steel bars and twisted cross bars together to form a rigid, open, and slip-resistant surface. The open pattern allows water, oil, and debris to drain freely into the trench below, preventing surface flooding and keeping walkways and traffic areas clean and safe.

Stainless Steel Grating

Serrated steel grating is a high-strength, slip-resistant metal grating manufactured with serrated edges on the load-bearing flat steel bars. The serrated profile creates additional grip points on the top surface of each bar, delivering superior traction in wet, oily, icy, or contaminated conditions. This makes serrated steel grating the preferred choice for industrial platforms, walkways, stair treads, drainage covers, and structural flooring where standard smooth grating may not provide sufficient slip resistance.
