Key features

S460M and Q460C hot rolled steel plates allow structural engineers to design taller buildings with reduced steel tonnage, saving foundation and construction costs.

Our hot rolled plates up to 3000mm width cover entire girder web depths without longitudinal splices, accelerating bridge fabrication and improving structural integrity.

S690QL hot rolled steel plate provides the ultra-high yield strength required for lightweight, long-reach crane booms while maintaining excellent low-temperature toughness.

AI-Powered supplier vetting

SummaryThe supplier is a trading company with a strong emphasis on exports, accounting for 90% of their sales. They have a clear focus on selling building materials and related products but lack evidence of certifications, which could affect credibility. The company does not manage overseas warehouses or have overseas agents, indicating limited international presence despite a high export percentage. Financially, there is no recorded revenue or profit over the last three years, raising concerns about financial stability. Their ability to innovate is evidenced by pioneering certain coating technologies, although there is no R&D capability with SDK availability. Production customization is available, but the overall production capacity is unclear.

Product Q&A

Q:What is the advantage of S460M over Q355B for a high-rise building column?

S460M hot rolled steel plate offers 460 MPa minimum yield strength compared to Q355B's 355 MPa. This 30% strength increase allows column sections to be lighter or carry higher loads, reducing structural steel weight and foundation requirements in high-rise construction.

Q:Can you provide hot rolled steel plates with Z35 through-thickness properties?

Yes, our Q420B, S460M, and Q460C hot rolled steel plates can be supplied with Z-direction tensile testing per EN 10164, achieving Z25 or Z35 quality for welded joints subject to high through-thickness loading in column base plates and bridge bearings.

Q:What surface preparation do you recommend for bridge steel plates before painting?

We recommend ordering hot rolled steel plates with a shop primer (pre-construction primer) coating for bridge fabrication. The primer provides temporary corrosion protection during fabrication and serves as an excellent base for the final paint system. Plates can also be supplied pickled and oiled or blast cleaned to SA 2.5.
