Customized Galvanized Steel Stair Tread With ISO9001 CE Certificate
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 wherever possible.
Recommended Stair Tread Widths
Bearing bars at 30mm pitch
Bearing bars at 40mm pitch
|Fixing hole centers||45||75||100||150|
Note: based on 5mm bearing bars.
Max. Stair Tread Lengths
Bearing bar measure
Steel grating specification
|Bearing bars at 30mm pitch||550||900||1300|
|Bearing bars at 40mm pitch||450||750||1200|
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 Webforge locations; these standard profiles are complimented by a custom manufacturing service.

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.
