Import 304 Checker Plate — Buy in wholesale FOB from Supplier in China

SS 304 checker plate from Jiangsu Steel Group Co., Ltd. is a cold-rolled stainless steel diamond plate measuring 4 feet by 8 feet with a 3.0 mm base thickness, manufactured from 18% chromium and 8% nickel austenitic stainless steel. The raised anti-slip pattern is formed during the rolling process to create a one-piece structural surface that maintains the full base metal thickness under the raised diamonds. This grade combines excellent formability with chromium-nickel corrosion resistance, making it suitable for demanding environments where both safety and durability matter. The supplier currently holds stock and invites immediate contact for availability confirmation.

The 304 grade contains 18% minimum chromium and 8% minimum nickel by mass, with maximum carbon content of 0.08% to preserve corrosion resistance after welding or forming. Typical mechanical properties for annealed 304 plate include tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40% in 50 mm. Checker plate patterns vary by producer; common diamond configurations include lentil, tear-drop, and five-bar patterns with raised heights of approximately 1.0-2.5 mm above the base plate. The 3.0 mm base thickness specified here represents a mid-range industrial choice, balancing structural rigidity with manageable weight for installation.

Primary applications span industrial flooring, stair treads, ramp surfaces, and marine deck installations where slip resistance and corrosion protection coincide. Buyers include shipbuilders, chemical plant constructors, commercial kitchen fabricators, and infrastructure contractors across Southeast Asia, the Middle East, and European ports. Standard export-worthy bundling applies; confirm with Jiangsu Steel Group Co., Ltd. whether wooden crating, steel strapping, or moisture-barrier wrapping is provided. The supplier's Shanghai address (10/f No.257 Siping Road, Hongkou) places it near Shanghai Port for containerised export, though inland trucking from Jiangsu mills should be clarified.

Jiangsu Steel Group Co., Ltd. maintains its registered office at 10/f No.257 Siping Road, Shanghai 200080, in the Hongkou district, placing it within Shanghai's core commercial zone rather than at a manufacturing site. The supplier is classified as an imported-tier entity on the platform, indicating its profile originated from external data ingestion rather than direct registration. Its trust tier is rated as harbor, which represents a baseline verification level without premium assurance. The response rate stands at 0.00% with an average response time of zero hours, suggesting no inbound enquiries have been processed through the platform or response tracking is inactive.

The listing offers SS 304 checker plate with explicit stock availability, a concrete specification set, and a direct invitation to contact for purchase. No manufacturing facility details, export licence numbers, ISO certifications, or quality management accreditations appear in the profile. Buyers should independently verify the supplier's mill relationships, whether it operates as a trader or manufacturer, and its track record in stainless steel export. The Shanghai location provides logistical advantages for port access, but due diligence on physical stockholding capacity and inspection protocols remains essential before commitment.
