Hdg Carbon Steel Iron Prefabricated Steel Stair Treads Checkered
Grating treads can be made from any grating pattern or profile, and to any
dimensions to suit the relevant stairway. In the interest of
economy we suggest that the recommended widths and lengths be used

Pattern and Load Bar selection
The tables below indicate the maximum width and length for stair
treads, depending on the combination of material, pattern and load
bar selected. Standard stair treads are available ex-stock from
Web-forge locations; these standard profiles are complimented by a
custom manufacturing service.
Steel grating advantage
1> light weight-easy to install and clean.
2> nice appearance-high strength-ventilation and light can pass
3> material saving-slip-resistant and safe
4> heavy loading and durable

Hot to order Steel Grating?
· It’s better that you can provide drawings with detailed
information like raw material, grating type, surface treatment,
· If you are not able to provide the drawing, we will design for
free according to your specific applications.
· A free design will need information like: area of application
(industrial platform, airport, docks, etc. drawings of this area
with detailed dimensions, boundary conditions, etc.
