Hot Rolled Steel Angle ASTM A572/A572m with RoHS Q235B 50X50X5, S235jr 100X100X10

Hot rolled steel angles, defined by their robust L-shaped cross-section, are fundamental structural components widely acclaimed for their exceptional load-bearing capacity, structural rigidity, and dimensional stability. Our hot rolled steel angles, manufactured in strict compliance with ASTM A572/A572M standards and RoHS directives, are available in two high-performance material grades (Q235B and S235jr) with specific dimensional specifications (50X50X5 and 100X100X10), engineered to fulfill the precise requirements of diverse industrial, architectural, and infrastructure applications.

ASTM A572/A572M certification is a hallmark of superior quality and performance for our hot rolled steel angles. This international standard specifies the technical requirements for high-strength low-alloy (HSLA) carbon steel products, ensuring our steel angles possess excellent weldability, formability, and resistance to atmospheric corrosion. Meanwhile, RoHS compliance guarantees that our products are free from hazardous substances (such as lead, mercury, and cadmium), making them environmentally friendly and suitable for applications in industries with strict environmental regulations, including electronics, automotive, and public infrastructure.

The product line features two meticulously selected material grades, each tailored to distinct application scenarios. Q235B, a carbon structural steel grade with a minimum yield strength of 235 MPa, exhibits reliable mechanical properties and outstanding weldability. The "B" grade denotes its ability to pass impact tests at room temperature, ensuring structural safety in general load-bearing scenarios. Our Q235B steel angle is supplied in the 50X50X5 specification (50mm leg length, 50mm leg length, 5mm wall thickness), making it ideal for light to medium-duty structural applications such as building frames, brackets, guardrails, and light machinery components. S235jr, a European standard (EN 10025) carbon structural steel, offers comparable performance to Q235B with a minimum yield strength of 235 MPa, characterized by excellent ductility and machinability. The 100X100X10 specification (100mm leg length, 100mm leg length, 10mm wall thickness) of our S235jr steel angle provides enhanced load-bearing capacity, suitable for heavy-duty structural projects including bridge bracing, industrial plant frameworks, and large-scale equipment bases.

The hot rolling manufacturing process further elevates the performance of our steel angles. During hot rolling, steel billets are heated to high temperatures and formed into the L-shaped cross-section, which refines the material's grain structure, improves internal uniformity, and enhances overall strength and toughness. The specific dimensional specifications (50X50X5 and 100X100X10) are strictly controlled during production, ensuring precise dimensional accuracy and consistent cross-sectional geometry. This dimensional precision facilitates easy assembly and integration with other structural components, enabling the construction of stable, efficient, and cost-effective load-bearing systems.

Our hot rolled steel angles undergo a comprehensive quality control process throughout the entire production cycle-from raw material inspection and hot rolling parameter monitoring to final dimensional measurement, mechanical property testing, and RoHS compliance verification. This rigorous quality assurance system ensures that each batch of products meets the requirements of ASTM A572/A572M standards and RoHS directives, free from defects such as cracks, inclusions, and uneven wall thickness. Whether for architectural construction, infrastructure development, or machinery manufacturing, our hot rolled steel angles (ASTM A572/A572M, RoHS compliant, Q235B 50X50X5 and S235jr 100X100X10) stand as a reliable choice for engineers and contractors seeking high-quality, compliant, and application-specific structural solutions.
