Hot Rolled Steel Angle A36 S275 S355 Ss400 A6 Ah36 Q195 100X100X6 160X160X10 Steel Angle

Our hot rolled steel angles, covering a comprehensive range of material grades including ASTM A36, European standard S275/S355, Japanese standard Ss400, ASTM A6, marine-grade Ah36, and Chinese standard Q195, are engineered to deliver robust performance and versatility for diverse structural, industrial, and marine applications. Complying with multiple international and regional material standards, these steel angles are fabricated from high-quality carbon and low-alloy steel with strictly controlled chemical compositions, ensuring consistent mechanical properties, structural integrity, and adaptability to varied load-bearing and environmental requirements.

Each material grade is tailored to specific performance demands, offering a graded spectrum of strength and functionality. ASTM A36, a widely used carbon structural steel, provides a minimum yield strength of 36,000 psi (250 MPa) and tensile strength of 58,000-80,000 psi (400-550 MPa), with excellent ductility and weldability for general structural framing. European S275 and S355 grades (EN 10025 standard) offer enhanced strength: S275 features 275 MPa minimum yield strength, while S355 delivers 355 MPa minimum yield strength, both ideal for medium to heavy-duty structural components. Japanese Ss400 (JIS G 3101) ensures 235 MPa minimum yield strength and 400-510 MPa tensile strength, suitable for general construction needs. ASTM A6, a standard for structural steel shapes, guarantees uniform dimensional accuracy and mechanical consistency for precision fabrications. Marine-grade Ah36 (ABS standard) provides exceptional toughness and corrosion resistance, with 355 MPa minimum yield strength, tailored for offshore and marine structures. Q195 (GB/T 700), a cost-effective low-carbon grade, offers 195 MPa minimum yield strength for light-duty structural applications.

These steel angles are manufactured via advanced hot rolling processes (conducted at 900-1100°C, above the steel's recrystallization point), which refine the grain structure to enhance toughness, impact resistance, and fatigue performance. We offer specific high-demand specifications, including 100X100X6 (100mm leg length, 6mm thickness) and 160X160X10 (160mm leg length, 10mm thickness), both featuring equal-legged (L-shaped) configurations for balanced load distribution. The hot rolling process ensures precise dimensional tolerances, consistent leg squareness, and uniform thickness across each piece, while the natural surface finish facilitates excellent adhesion for subsequent protective treatments.

Versatile in application, these hot rolled steel angles are widely utilized in commercial and industrial construction (building frames, bracing, floor joists), infrastructure projects (bridges, walkways, guardrails), marine and offshore structures (ship hulls, offshore platforms), heavy machinery fabrication (equipment frames, brackets), and light-duty structures (storage racks, partitions). Their compatibility with various surface treatments-galvanization, epoxy coating, powder coating-significantly improves corrosion resistance, extending service life in harsh environments such as coastal areas, industrial zones, and offshore locations.

Stringent quality assurance protocols are implemented throughout production, including chemical composition analysis (optical emission spectrometry), mechanical property testing (tensile, yield, elongation), dimensional inspection with precision tools, and surface defect detection. These measures ensure full compliance with respective standards (ASTM, EN, JIS, ABS, GB/T) and consistent performance across every batch. For engineers, contractors, and fabricators seeking multi-standard, high-performance hot rolled steel angles with specific size options, our product lineup offers unparalleled adaptability and reliability for diverse project requirements.
