SS400, Q235B, S235JR Hot Rolled Steel Coils / Checkered Steel Plate, 2000mm

Product Specification

SS400, Q235B, S235JR Hot Rolled Steel Coils / Checkered Steel Plate, 2000mm -12000mm Long

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 helps improve 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 914mm to 1500mm and lengths from 2000mm to 12000mm. The thickness range extends from 1.5mm to 200mm, which makes it suitable for both light fabricated panels and heavier structural plate applications.

2．Technical Solution

The product is manufactured as hot rolled steel plate with a checkered surface pattern. In actual use, the steel grade determines the base strength and fabrication behavior, while the surface pattern improves contact friction on the exposed side.

SS400 and Q235B are generally selected for general fabrication and standard structural flooring use. Q345B and S235JR are more suitable where higher structural requirement or different project standard matching is needed. ASTM A36 can be selected when the project follows ASTM structural steel routing.

For this type of product, thickness should be selected according to support spacing, service load, and fabrication route rather than surface pattern alone.

3．Specifications

4．Application

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

5．Processing

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

6．Advantages

• The raised checkered surface helps improve grip compared with plain hot rolled plate.
• The 914–1500mm width range supports mainstream structural plate cutting and fabrication layouts.
• The available length up to 12000mm is suitable for larger structural panels and long fabricated parts.
• The thickness range from 1.5mm to 200mm covers both light and heavy plate applications.
• Multiple structural grade options allow the product to be matched to different fabrication routes and project standards.

7．How to Choose

• Choose SS400 or Q235B for general fabrication and standard structural flooring use.
• Choose Q345B or S235JR when higher strength level or project-specific standard matching 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 length according to blank layout, cutting yield, transport condition, and installation size.
