Authentic Steel is the export department of Winroad Group and a professional manufacturer and exporter of hot rolled chequered floor coils and sheets—also known as checkered steel coils, diamond plate coils, or anti-slip steel coils. From our production hub in Tianjin, China, we supply these materials to industrial flooring contractors, transportation equipment builders, marine infrastructure projects, and steel distributors in 78+ countries. We provide mill-direct pricing, custom processing, and rapid export dispatch through Tianjin Port.
Our hot rolled chequered coils and sheets are produced with a raised surface pattern for multi-directional traction and wear resistance. According to our brochure, the standard HRC/Sheet range includes:
Thickness: 0.8–19 mm
Width: 900–2000 mm
Length: 1000–12000 mm or as needed
Coil weight: 5–25 MT
Surface: Checkered
Grades: Q195 / Q235B / Q345B / Q355B / SS400 / A36, etc.
Specific chequered thickness ranges, pattern types, and higher grades such as S235JR or S355JR are available on request. Please share your target application and load requirement so we can recommend a suitable specification.
Tear Drop Pattern: Available on request. Suitable for walkways, bus aisles, and public infrastructure where anti-slip friction and easy cleaning are required.
Diamond Pattern: Available on request. Suitable for industrial machinery platforms, transport decks, and heavy-duty conditions requiring multi-directional grip.
Industrial mezzanine floors and walkway platforms
Stair treads, ramps, and warehouse storage decks
Heavy truck bed lining and trailer floors
Bus aisles and shipping container decking
Ship deck plating and marine gangways
Elevator cabin floors and municipal engineering covers
We support flexible processing for project-specific requirements:
Custom slitting into narrow chequered strips
Cut-to-length chequered steel plates
Flattened sheets ready for installation
Surface inspection and pattern uniformity checks
Mill Test Certificate (MTC) available on request
Third-party inspection available on request
Custom slitting width, cut length, and edge condition can be discussed according to your production line and project drawings.
Every batch undergoes inspection, including pattern height uniformity, tensile strength, surface condition, and dimensional checks. Additional testing is available on request. A Mill Test Certificate (MTC) can be supplied on request.
To reduce moisture damage, surface rust, and edge deformation during ocean transport, our chequered coils and sheets use multi-layer export packaging: rust-inhibiting VCI paper, plastic moisture barriers, metallic corner protectors, and high-tensile steel banding on heat-treated wooden skids or pallets. This packaging is suitable for long-distance container shipment and safe unloading.
