Hot rolled carbon mild steel angle steel, available in Q235 and SS400 grades, is a fundamental and widely utilized structural material in global construction, industrial manufacturing, and infrastructure projects. Characterized by its classic L-shaped cross-section, hot-rolled production process, and superior carbon mild steel properties, this product integrates excellent structural stability, reliable load-bearing capacity, and cost-effectiveness. It serves as a cornerstone component for fabricating frames, brackets, trusses, and supports, catering to both general-purpose and specialized structural needs.

Q235 carbon mild steel angle steel, a benchmark grade in carbon steel materials, features a minimum yield strength of 235MPa. Fabricated via advanced hot-rolling technology, it achieves a uniform grain structure that ensures consistent mechanical performance, excellent ductility, and superior weldability. The hot-rolling process also imparts a smooth surface finish and precise dimensional tolerance, facilitating easy on-site fabrication such as cutting, bending, and welding. Typical applications of Q235 angle steel include building steel frames, bridge auxiliary structures, mechanical equipment bases, storage racks, and temporary support systems, making it a versatile choice for medium-light structural engineering.

SS400 carbon mild steel angle steel, a globally recognized Japanese industrial standard (JIS) grade, corresponds to a minimum yield strength of 235MPa (equivalent to Q235 in performance). It is manufactured from high-quality carbon mild steel and processed through hot rolling, ensuring outstanding comprehensive properties-including reliable tensile strength, good formability, and excellent machinability. SS400 angle steel is widely adopted in international projects, particularly in machinery manufacturing, shipbuilding, automotive components, and large-scale construction projects. Its consistent quality and compatibility with international standards make it a preferred choice for global customers seeking reliable structural steel materials.

Both Q235 and SS400 hot rolled carbon mild steel angle steels belong to the low-carbon steel category, with carbon content typically ranging from 0.12% to 0.20%. This low-carbon composition is the key to their excellent weldability and formability, allowing for secure and stable connections in complex structural assemblies. The hot-rolling manufacturing process not only enhances the material's mechanical properties but also ensures cost-effectiveness by optimizing production efficiency. To extend service life in various environments, optional surface treatments are available, such as hot-dip galvanizing, epoxy coating, or anti-rust oiling, which effectively improve corrosion resistance in indoor, outdoor, and moderately humid conditions.

Our Q235 and SS400 hot rolled carbon mild steel angle steels are offered in a comprehensive range of specifications, including equal and unequal leg types. Common leg lengths range from 20mm to 200mm, with thicknesses from 3mm to 24mm, and custom lengths (up to 12 meters) are available to meet specific project requirements. All products undergo rigorous quality control procedures, including testing of chemical composition, mechanical properties (yield strength, tensile strength, elongation), and dimensional accuracy, ensuring full compliance with relevant national and international standards (GB/T, JIS G 3101).
