Product Specification

Galvanized / Galvalume ASTM A36, Q235B, Q345B Hot Rolled Checkered Steel Plate / Coils

1．Product Overview

Hot rolled checkered steel plate is used where a raised surface pattern and a structural steel base are both required. Compared with plain hot rolled plate, the patterned surface improves grip in working areas, access platforms, ramps, and fabricated floor sections, while the steel substrate provides the required load-bearing capacity.

This product range covers widths from 700mm to 3000mm and thickness from 1.5mm to 200mm. It is suitable for structural flooring, platform panels, fabricated access plates, and other industrial steel parts where surface grip and plate strength need to be considered together.

2．Technical Solution

The product is manufactured as hot rolled steel plate with a patterned top surface. In practical use, the base steel grade controls the structural strength and fabrication behavior, while the raised pattern improves contact friction on the exposed side.

Q235 and Q345 are commonly selected for general fabrication and structural use. ASTM A36 is suitable where the project follows ASTM structural steel routing. Thickness should be selected according to support spacing, service load, welding route, and required rigidity rather than surface pattern alone.

3．Specifications

4．Application

• This material is suitable for structural flooring and industrial walking areas where a patterned surface is required.
• It can be used for platforms, ramps, stair components, equipment flooring, flange-related fabricated parts, container plate applications, and general construction steel parts.
• It is also suitable for boiler plate and other industrial plate applications where hot rolled strength and surface grip need to be considered together.

5．Processing

• The plate can be supplied in custom cut length according to project requirement.
• It is suitable for flame cutting, plasma cutting, drilling, welding, bending, and general structural fabrication.
• Thickness, width, and cut size should be selected together according to final part geometry, fabrication route, transport condition, and installation method.

6．Advantages

• The raised checkered surface improves grip compared with plain hot rolled plate.
• The 700–3000mm width range supports both standard plate cutting and wider structural panel layouts.
• The thickness range from 1.5mm to 200mm covers light plate to heavy plate applications.
• Q235, Q345, and ASTM A36 provide practical grade options for different fabrication and structural requirements.
• Hot rolled checkered plate is suitable for industrial fabrication where patterned surface performance and base plate strength are both needed.

7．How to Choose

• Choose Q235 for general fabrication and standard structural flooring use.
• Choose Q345 when higher strength level is required.
• Choose ASTM A36 when the project follows ASTM structural steel routing.
• Choose thickness according to service load, support spacing, and required stiffness.
• Choose width and cut length according to blank layout, cutting yield, transport limits, and installation size.
