Our Ss400, A36, and Q235 angle steel are high-quality structural products specifically tailored for construction applications, integrating reliable mechanical properties, excellent processability, and cost-effectiveness. As a fundamental component in construction engineering, this angle steel features a standard right-angle cross-sectional design, which ensures efficient stress distribution, stable load-bearing capacity, and seamless force transmission. Manufactured in strict compliance with corresponding international and national standards, these angle steels are widely recognized and trusted in the construction industry, serving as core materials for various structural framing, bracing, and reinforcement systems.
Ss400, A36, and Q235 are globally prevalent carbon structural steel grades, each with distinct and superior performance characteristics suitable for construction scenarios. Ss400, adhering to Japanese Industrial Standards (JIS), boasts a minimum yield strength of 400 MPa, offering robust load-bearing capacity for medium to heavy-duty structural components in construction projects. A36, a classic American Society for Testing and Materials (ASTM) standard grade, has a minimum yield strength of 250 MPa and excellent ductility, making it a versatile choice for residential, commercial, and industrial building structures worldwide. Q235, a Chinese national standard (GB/T 700) grade with a minimum yield strength of 235 MPa, exhibits exceptional formability and weldability, coupled with cost-effectiveness, serving as a staple material for general construction frameworks and ordinary structural components. All three grades possess outstanding compatibility with common construction fabrication processes, enabling easy cutting, bending, welding, and assembly to meet diverse project design requirements.
The manufacturing process of our Ss400, A36, and Q235 angle steel adheres to rigorous industrial standards to ensure consistent quality and performance. Raw steel billets of each grade undergo strict pre-inspection, including detailed chemical composition analysis and mechanical property verification, to eliminate substandard materials. The core production adopts advanced hot-rolling technology: billets are heated to an optimal high temperature (above 1000°C) to achieve ideal plasticity, then precisely rolled through a series of professional mills to form the standard angle steel profile. This hot-rolling process refines the steel's grain structure, significantly enhancing its toughness and tensile strength while ensuring precise dimensional accuracy (leg length, thickness, right angle deviation) and a smooth surface finish. For construction projects in humid or outdoor environments, optional surface treatments such as galvanization, anti-rust painting, or epoxy coating are available to improve corrosion resistance and extend the product's service life.
Ss400, A36, and Q235 angle steel are extensively applied in various construction projects, covering residential buildings, commercial complexes, industrial workshops, warehouses, bridges, and infrastructure facilities. In specific applications, Q235 is often used for light to medium-load components such as roof trusses, wall frames, door and window frames, and concrete reinforcements due to its cost-effectiveness and formability. A36, with its balanced strength and ductility, is widely employed in general building structures, including floor beams, columns, and bracings, as well as bridge auxiliary structures. Ss400, leveraging its higher yield strength, is suitable for heavy-duty construction components such as large-span structural framing, industrial machinery bases, and high-load support systems. The three grades complement each other, allowing construction engineers and contractors to flexibly select based on project load requirements, environmental conditions, and budget plans, ensuring optimal structural safety and cost-efficiency.
