Product Specification

30X3mm Hot Dipped Steel Grating Panels Galvanized Steel Bar Grating

1.Product Overview

Hot dipped galvanized steel grating panels are used where load bearing support, open drainage, and safe walking access are required in one component. This product is suitable for work platforms, catwalks, transportation servicing areas, vehicle steps, and other structural access locations where strength and open area performance need to be considered together.

The featured 30x3mm bearing bar configuration is a practical option for light to medium duty grating applications. With a minimum panel width of 824mm and a galvanized surface, it is designed for industrial and outdoor environments where corrosion protection and service durability are important.

2.Technical Solution

The grating is built from flat bearing bars and cross bars arranged into a pressure welded grid structure. In actual use, the final performance depends on the bearing bar size, bar spacing, cross bar type, support span, and surface treatment.

The page lists flat steel in ordinary plain type, anti-skid tooth type, and I section type. Cross bars can be round bar, twisted square bar, square bar, or hexagonal bar. This matters in practical selection because the bearing bar controls the load response, while the cross bar and pitch affect opening size, drainage behavior, and panel rigidity.

Hot dip galvanized surface treatment is used to improve corrosion resistance and maintain surface durability in outdoor or industrial service conditions.

3.Specifications

4.Application

• This material is suitable for work platforms, catwalks, transportation servicing areas, and vehicle steps.
• It can also be used for stair treads, structural access flooring, industrial platforms, and open-grid locations where drainage, lighting transmission, and ventilation are required together with load-bearing support.
• For industrial service, it is particularly suitable where a self-draining walking surface is preferred over closed plate construction.

5.Processing

• The grating can be fabricated from different flat steel sizes and cross bar forms according to project requirement.
• It is suitable for cutting, welding, edge finishing, and panel fabrication according to platform, step, or walkway layout.
• For actual project selection, the bearing bar direction and support spacing should be confirmed before finalizing the panel specification.

6.Advantages

• The pressure welded grid structure provides high load bearing capacity with relatively low self weight.
• The open-grid format supports ventilation, lighting transmission, heat dissipation, and water drainage.
• Hot dip galvanized surface treatment improves corrosion resistance for outdoor and industrial environments.
• Plain, anti-skid tooth, and I type bar options allow the grating to be matched to different access and safety requirements.
• The structure is easy to lift, install, and maintain in platform and walkway applications.

7.How to Choose

• Choose 30x3mm bearing bar when the application is a light to medium duty platform or walkway and the support span is moderate.
• Choose anti-skid tooth type when the walking surface is likely to be wet or requires better foot grip.
• Choose larger flat steel sizes when the load is higher or the support span is longer.
• Choose cross bar spacing according to the required balance between drainage opening, rigidity, and walking comfort.
• Choose hot dip galvanized finish when the panel will be used outdoors, in humid conditions, or in industrial environments with corrosion exposure.
