Anti-slip Galvanized Stair Tread Grating for Outdoor Stairs

The galvanized stair tread grating is manufactured from parallel load-bearing bars connected by cross bars. Welded carrier plates at both ends allow the tread to be bolted or welded to steel stair stringers.

For outdoor stairs exposed to rain, mud or snow, serrated bearing bars provide additional surface grip. A checker-plate or perforated nosing can be added to define the front edge and improve contact at the leading part of the step.

The open-grid structure allows water, dirt and light debris to pass through rather than collect on the walking surface. Hot-dip galvanizing protects the fabricated steel tread, side plates and welded joints against outdoor corrosion.

Stair tread dimensions, bearing-bar spacing, nosing type and mounting-hole positions can be manufactured according to stair drawings and project loading requirements.

Serrated Anti-Slip Surface

Notched bearing bars provide additional grip compared with smooth steel grating, making them suitable for wet outdoor stairs and industrial access routes.

Open Drainage Design

The open-grid surface allows water, snow and dirt to pass through, helping reduce accumulation on the stair tread.

Hot-Dip Galvanized Protection

Galvanization covers the steel grating and welded components with a corrosion-resistant zinc layer for outdoor installation.

Strong Load-Bearing Structure

Bearing-bar depth, thickness and spacing can be selected according to the tread width, clear span and required pedestrian load.

Visible Stair Nosing

Checker-plate, perforated or abrasive nosing can identify the front edge of the step and provide additional foot contact.

Ready-to-Install Side Plates

Pre-punched carrier plates or welded end angles allow the stair tread to be attached directly to steel stringers.

Customized Dimensions

Tread width, depth, bar spacing, nosing and bolt-hole positions can be fabricated to match new or existing stair structures.

Industrial Access Stairs

Serrated steel grating treads are suitable for factories, production lines and equipment-access stairways.

Outdoor Platforms

Galvanized stair treads provide access to maintenance platforms, catwalks, tanks and elevated steel structures.

Fire Escape Stairs

Open-grid metal treads can be fabricated for external emergency stair structures according to approved building requirements.

Municipal Facilities

The stair grating can be used at water-treatment plants, pumping stations, utility sites and other public infrastructure.

Warehouses and Logistics Centers

Durable steel treads are suitable for mezzanine stairs, loading areas and warehouse access systems.

Commercial Buildings

Galvanized stair treads can be installed on external service stairs around offices, retail properties and parking facilities.

Marine and High-Moisture Areas

Special galvanized or stainless steel configurations can be selected for environments exposed to frequent moisture.

Frequently Asked Questions

What makes the stair tread anti-slip?

Serrated bearing bars and an optional textured nosing provide additional surface grip. However, the tread should not be described as completely slip-proof.

Why is open grating suitable for outdoor stairs?

The open structure allows rainwater, snow and dirt to pass through instead of accumulating on the step surface.

Can the stair tread dimensions be customized?

Yes. Width, depth, bearing-bar dimensions, spacing, side plates and mounting holes can be fabricated according to the stair drawing.

Are mounting plates included?

Welded carrier plates or end angles with pre-punched bolt holes can be supplied as part of each stair tread.

How is the load capacity determined?

Load capacity depends on the bearing-bar size, spacing, tread width, clear span, steel grade and connection method.

Can stainless steel be used instead of galvanized carbon steel?

Yes. Stainless steel options are available for projects requiring additional corrosion resistance or a specific material finish.

What information is needed for a quotation?

Please provide the tread width, depth, quantity, bearing-bar specification, surface type, nosing, stringer spacing, mounting-hole layout and required load.
