Welded steel stair treads
Welded stair treads with bearing and cross bars welded at each intersection for industrial plant access, platforms, and heavy-duty service areas.
Product Description
Welded stair treads are fabricated from steel grating with bearing bars and cross bars welded at each intersection. They provide strong load-bearing capacity, good drainage, and anti-slip performance for industrial stairs, plant access systems, and platform stairways. Available in standard spacing formats with nosing options and hot-dip galvanized or painted finishes.

Stair tread applications by sector
Data centers
Access stairs to roof plant and data-hall mezzanines—match slip and load to owner standards.
Power generation
Boiler and turbine stair towers with washdown and condensate exposure.
Oil & gas
Module escape stairs and offshore companionways requiring serrated profiles and documented loads.

Detailing notes
Usually matches welded platform mesh for visual continuity.
Frequently asked questions
How is stair tread span defined?
Clear distance between stringers supporting the tread; verify with the supplier table for the model.
Plain or serrated nosing?
Match platform slip strategy; serrated nosing is common in wet plants.
Bolted vs welded treads?
Bolted eases replacement; welded is common for fixed industrial stairs.
Load basis?
Typically uniform load per stair width plus maintenance concentrated load if owner requires.
Galvanizing after fabrication?
Standard for carbon steel; vent per detail drawings.
Riser and going tolerances?
State expected fabrication tolerance class so nosing lines stay straight across flights.
Custom marking for escape routes?
Photoluminescent nosing or paint bands may be added—state in RFQ.
