Bar Grating Stair Treads Overview
Bar grating stair treads are fabricated from open-grid grating panels and prepared as finished stair components with the required width, depth, surface, nosing and side mounting details.
They provide drainage and ventilation while maintaining an open walking surface for industrial stairs, maintenance access and elevated structures.
Treads can be produced from welded, press-locked and other suitable grating constructions depending on the material, load, appearance and project requirements.
Bar Grating Stair Tread Components
Grating Tread
The main walking surface is produced from the selected bar grating construction, bearing-bar size and spacing.
Nosing
A front nosing can provide a defined leading edge and additional visibility or traction depending on the selected design.
End Plates
Side plates can be attached to the tread for connection to stair stringers or supporting structures.
Mounting Holes
Bolt holes or other fixing details can be prepared according to approved installation drawings.

Bar Grating Stair Tread Construction Options
Welded Grating Stair Treads
Rigid welded grating is widely used for industrial steel stair treads and general access systems.
Press-Locked Grating Stair Treads
Press-locked grating provides a clean and consistent grid for industrial and architectural stair projects.
Serrated Grating Stair Treads
Serrated bearing bars provide additional traction for wet, outdoor and demanding walking conditions.
Close-Mesh Stair Treads
Reduced spacing can provide smaller openings where the project requires a more compact walking surface.
Bar Grating Stair Tread Materials
Carbon Steel
Strong and economical grating treads for industrial stairs and general access systems.
Galvanized Steel
Zinc-protected steel treads for outdoor and moisture-exposed stair systems.
Stainless Steel
Corrosion-resistant grating treads for processing and demanding service environments.
Aluminum
Lightweight and corrosion-resistant treads for suitable industrial and architectural stair projects.
Where Bar Grating Stair Treads Are Used
Bar grating stair treads are commonly used in industrial stairs, maintenance access systems, platforms, processing facilities and outdoor structures.

Smooth vs. Serrated Grating Stair Treads
| Comparison | Smooth Stair Treads | Serrated Stair Treads |
|---|---|---|
| Surface | Conventional bearing-bar top | Notched bearing-bar surface |
| Traction | General walking conditions | Additional traction |
| Indoor Use | Common | Also available |
| Wet / Outdoor Use | Depends on environment | Often preferred |
| Cleaning | Simple open surface | Depends on debris and process |
| Selection | General access | Slippery or demanding conditions |
Choose smooth grating stair treads for general industrial access where additional traction is not required.
Choose serrated grating stair treads for wet, oily or outdoor stair systems where improved surface grip is important.
Bar Grating Stair Treads vs. Cut Grating Panels
| Feature | Finished Stair Tread | Cut Grating Panel |
|---|---|---|
| Finished Width & Depth | Yes | Panel dimensions only |
| Nosing | Available | Normally none |
| End Plates | Fabricated for stairs | Normally none |
| Mounting Holes | According to stair drawing | Normally none |
| Installation Purpose | Stair system | Flooring / platform |
| Supply Form | Finished component | Grating panel |
A finished grating stair tread is a fabricated stair component, not simply a rectangular piece cut from a grating panel.
Case Study : Galvanized Grating Stair Treads for an Industrial Access Tower
This project required multiple galvanized grating stair tread sizes for a steel maintenance tower with prefabricated stair stringers.
Project Requirement
The contractor supplied stair drawings showing several flight widths and mounting-hole arrangements.
The treads needed to match the prefabricated steel stringers, while serrated walking surfaces were required for the outdoor installation.
Each flight contained repeated tread sizes together with several special top and bottom treads.
Manufacturing Solution
Galvanized serrated bar grating stair treads were fabricated according to the approved stair schedule.
Each tread was cut to the required width and depth, fitted with front nosing and prepared with end plates.
Mounting holes were produced according to the stair-stringer drawings.
Special tread sizes were separated from the repeated standard project sizes.
Inspection & Packaging
Tread dimensions, nosing, end plates and mounting-hole positions were checked before shipment.
Each tread group was labeled by stair flight and installation position, then packed in sequence for easier onsite assembly.
Bar Grating Stair Tread FAQs
