Q235B Q355 Hot Rolled Carbon Steel Plate with 6-40mm Thickness and Embossed Surface for Construction and Engineering

Wuxi Sylaith Special Steel Co., Ltd. supplies high-quality Q235B Q355 hot rolled carbon steel plates with medium thickness, embossed surface, and customizable processing services including cutting, bending, punching, welding, and decoiling. Adopting advanced hot rolling technology and strict quality control, our steel plates meet multiple international standards (AISI, ASTM, BS, DIN, GB, JIS) and hold CE, RoHS, and ISO 9001 certifications.

With a thickness range of 6–40mm and width of 1001–1250mm (customizable), these non-alloy high-strength steel plates feature ±1% dimensional tolerance and skin pass treatment for stable performance, excellent weldability, and strong load-bearing capacity. Ideal for shipbuilding, boilers, containers, pipe manufacturing, construction, home appliances, and automotive industries, they deliver reliable performance for large-scale engineering projects and industrial manufacturing.

• Construction & Engineering: Building structures, steel frames, bridge components, and infrastructure projects
• Shipbuilding & Marine: Ship hull plates, marine structural parts, and offshore engineering components
• Boiler & Pressure Vessel: High-strength boiler plates and pressure vessel shells
• Container Manufacturing: Container body panels and structural reinforcements
• Pipe & Steel Products: Raw material for welded pipes, cold-rolled steel products, and small tools
• Automotive & Home Appliances: Vehicle chassis parts, appliance shells, and mechanical equipment brackets
• Industrial Manufacturing: Machined parts, stamping components, and general engineering fabrications

Q235B Q355 carbon steel plates are produced via hot rolling technology: steel billets are heated to high temperature, rolled into flat sheets under high pressure, then cooled and leveled. This process refines the steel’s internal structure, enhancing strength, ductility, and toughness.

Q235B (yield strength ≥235MPa) offers good plasticity and weldability for general engineering; Q355 (yield strength ≥355MPa) provides higher strength for heavy-load structures. The embossed surface improves anti-slip performance, while precision cutting/bending/punching ensures adaptability to diverse project requirements.

Q235B is a general carbon steel with yield strength ≥235MPa, suitable for light-load applications. Q355 is high-strength low-alloy steel with yield strength ≥355MPa, ideal for heavy-duty engineering and structural projects.
