Steel Grade Q195-Q420 Series, SS400-SS540 Series, S235JR-S355JR Series, ST Series, A36-A992 Series, Gr50 Series,etc

Q195/Q235 coils offer superior ductility and weldability (ISO/API certified), ideal for cost effective applications such as furniture, automotive parts and building panels. Q345/Q355 step up with increased tensile strength (520-680 MPa), perfect for machinery and pressure vessels.The star of the range, Q420 (GB/T 1591-2018), redefines toughness: 420MPa yield strength, -20℃ impact toughness and anti-fatigue properties make it unbeatable for wind turbine towers, bridges and offshore platforms. Customise thickness (0.8-100mm) and width (45-2200mm) with hot/cold rolling, slit edges or anti-rust coatings .

The SS400 series - ideal for bridges, machinery and automotive frameworks - offers cost-effective durability with superior weldability and cold formability. Upgrade to SS540 for high impact resistance in heavy construction and offshore platforms, ensuring stability under extreme loads.Available in thicknesses of 1.8-25.4mm and widths up to 2400mm, with slit edges or anti-corrosion coatings. Compliant with JIS, ASTM A36 and ISO standards, backed by anti-corrosion treatments for extended service life.Trusted by leading shipbuilding, energy and infrastructure companies.

S235JR offers cost-effective durability for lightweight structures and machinery, while S355JR dominates with 355MPa strength and -20℃ impact toughness for heavy-duty structures such as bridges and wind turbines.Manufactured to EN 10025 standards and ISO certified, these coils feature hot-rolled precision with customisable thicknesses (1.8-25.4mm) and anti-corrosion coatings (epoxy, galvanised) for seamless welding and extreme environments.Tailored processing (cutting, threading) - trusted by leaders in energy, shipbuilding and infrastructure.

ST series carbon steel coils (e.g. ST12/ST13/ST14) performance for precision-driven applications. Widely used in automotive panels, white goods housings, structural brackets and lightweight structural components, these coils excel in cold forming, deep drawing and welding processes.

The A36-A992 series of carbon steel coils offer progressive strength: A36, a cost-effective general purpose steel, is ideal for structural frames, machine bases and brackets, while the high-strength A992 (low carbon, low alloy) is designed for skyscrapers, bridges and seismic structures where high load-bearing capacity is required. These coils feature uniform thickness (1.2-25mm), excellent machinability and corrosion resistant options (galvanised/painted) for harsh environments such as coastal or industrial plants.
