824mm Galvanised Steel Walkway Grating Steel Grating Panels Step Steel Frame

Product Specification

824mm Galvanised Steel Walkway Grating Steel Grating Panels Step Steel Frame Lattice

1.Product Overview

Hot dipped galvanized steel grating is used where open drainage, load-bearing support, and safe walking access are required in one component. This product is suitable for industrial walkways, step frames, stair treads, floor platforms, trench covers, and structural access areas.

The open-grid structure is designed for applications where drainage, ventilation, lighting transmission, and surface grip are important. The minimum listed width is 824mm, and the page highlights a 30x20 grating configuration for walkway and floor use.

2.Technical Solution

The grating is formed from flat bearing bars arranged at a defined spacing and locked by cross bars. In practical use, the final load response depends on the bearing bar size, bearing bar pitch, cross bar type, cross bar pitch, and support span.

The product can be supplied with hot dip galvanized, cold dip galvanized, painted, powder coated, or untreated surface. For outdoor and industrial service, hot dip galvanized treatment is generally selected because the zinc layer protects weld zones, edges, and exposed bar surfaces more effectively than untreated steel.

The page also lists plain flat bar, serrated flat bar, and I bar options. Plain type is suitable for standard structural flooring. Serrated type is more suitable for wet or slip-sensitive access areas. I bar type is more suitable when lower self-weight is an additional consideration.

4.Application

• This material is suitable for industrial steel floor grating, steel walkway grating, stair treads, platform flooring, trench covers, ditch covers, and structural access systems.
• It can be used in buildings, metal structures, municipal works, plant walkways, petrochemical projects, power stations, shipbuilding, transport facilities, and general industrial platforms where open-grid drainage and walking safety are required together.
• It can also be used in balcony protection, rail barriers, highway barriers, and other fabricated steel access systems when the panel layout and support structure are matched to the project requirement.

5.Processing

• The grating can be fabricated according to drawings and project dimensions. It is suitable for cutting, welding, edge banding, and shaped panel production.
• For walkway and floor applications, the bearing bar direction should follow the support span. For stair and trench cover use, the opening size, support frame, and service load should be confirmed before finalizing the bar size and pitch.
• When hot dip galvanizing is required, fabrication is usually completed before galvanizing so that cut edges and weld areas are coated together.

6.Advantages

• The open-grid structure supports drainage, ventilation, and light transmission while still providing a load-bearing walking surface.
• Hot dip galvanized treatment improves corrosion resistance for outdoor, wet, and industrial environments.
• The listed bearing bar sizes and pitch options allow the grating to be selected according to span and load requirement instead of using one fixed panel type.
• Plain, serrated, and I bar options allow the product to be matched to standard flooring, anti-slip access, or lower self-weight applications.
• The product can be fabricated to drawing, which is useful for non-standard openings and structural layouts.

7.How to Choose

• Choose the bearing bar size according to actual support span and service load.
• Choose smaller bar sizes for lighter pedestrian access with shorter spans.
• Choose larger bar sizes such as 30x5, 32x5, 40x5, or above when the support span is longer or the load is higher.
• Choose serrated flat bar when the walkway or stair surface is likely to be wet.
• Choose hot dip galvanized treatment when the grating will be used outdoors, in humid locations, or in industrial environments with higher corrosion exposure.
