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 through
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, quantities, etc.
· 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.
