Q195, SS490, Astm A786 Checkered Plate 1200mm - 1800mm Width Steel Checkered Plate

Q195, SS490, Astm A786 Checkered Plate 1200mm - 1800mm Width Steel Checkered Plate

1．Product Overview

Hot rolled checkered steel plate is used where a raised surface pattern and a hot rolled base plate are both required. Compared with plain hot rolled plate, the embossed pattern helps improve surface grip in walking and contact areas, while the base plate thickness and steel grade remain the main factors for load-bearing performance.

This specification is positioned for medium to heavy plate use, with width from 1200mm to 1800mm and thickness from 8mm to 50mm. It is suitable for structural flooring, platform plates, industrial access areas, and fabricated plate parts that require a patterned surface.

2．Technical Solution

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

For this product range, Q195 and Q235 are generally used for general fabrication, while Q345, SS400, and SS490 are more suitable where higher structural requirement or different project standards are involved. Thickness should be selected according to span, support condition, and service load rather than surface pattern alone.

3．Specifications

4．Application

• This material is suitable for industrial flooring and working platforms where a patterned walking surface is required.
• It can be used for stair treads, ramps, access decks, truck or equipment floor plates, and general structural flooring panels.
• It is also suitable for fabricated steel parts where surface grip and plate stiffness 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, welding, drilling, and general structural fabrication.
• Thickness and plate size should be selected together according to final part geometry, welding route, and installation method.

6．Advantages

• The raised surface pattern helps improve grip compared with plain plate.
• The 1200mm–1800mm width range is suitable for larger structural flooring blanks and cut parts.
• The 8mm–50mm thickness range covers medium to heavy plate applications.
• Multiple grade options allow the plate to be matched to general fabrication use or higher structural requirement.
• Hot rolled patterned plate is suitable for industrial fabrication where surface texture and plate strength are both needed.

7．How to Choose

• Choose Q195 or Q235 for general fabrication and standard structural flooring use.
• Choose Q345 or SS490 when higher strength level is required.
• Choose thickness according to support spacing, service load, and required stiffness.
• Choose width and length according to blank layout, cutting yield, and installation size.
• Choose the final grade and plate thickness together when the product will be welded into structural assemblies.
