Our A36 Hot Rolled Angle Iron, available in the precise specification of 25252.5mm (equal leg) as well as customizable equal/unequal L profiles, stands as a high-performance structural component engineered for precision, durability, and versatility. Rooted in the globally recognized A36 carbon steel grade (compliant with ASTM A36 standards), this angle iron embodies the material's inherent advantages: a minimum tensile strength of 36 ksi (248 MPa), excellent yield strength (30 ksi minimum, 207 MPa), and superior ductility (20% minimum elongation in 200mm), making it a reliable choice for load-bearing and structural support applications across industries.
The hot-rolled manufacturing process is a defining feature of this product, imparting critical material benefits that distinguish it from cold-formed alternatives. During hot rolling, A36 steel is processed at temperatures exceeding 1,000℃, which refines its grain structure to achieve uniform density-eliminating internal defects such as porosity or microcracks that could compromise structural integrity. This process also enhances the steel's machinability and formability: the hot-rolled angle iron can be easily cut, drilled, welded, or bent on-site without excessive brittleness, adapting seamlessly to complex fabrication requirements. Additionally, the hot-rolled surface retains a natural, slightly textured finish that improves adhesion for protective coatings (e.g., hot-dip galvanizing, epoxy painting), extending the product's service life in outdoor, humid, or corrosive environments.
The 25*25*2.5mm equal-angle specification represents a compact yet robust option, tailored for lightweight to medium-load structural needs. The 25mm equal leg length ensures balanced force distribution, while the 2.5mm thickness provides sufficient rigidity to resist bending or torsion-ideal for applications such as residential wall studs, small-scale steel trusses, furniture frames, and auxiliary support brackets in industrial equipment. For scenarios requiring asymmetric load-bearing or space-efficient design, our product line also includes unequal L-profile angle irons (with customizable leg length ratios, e.g., 3020mm, 4025mm) under the A36 grade. These unequal angles excel in applications like edge reinforcement for large panels, stair stringers, and structural connections where one leg needs to bear greater load or align with uneven surfaces, offering flexible solutions to match diverse project geometries.
As a mild steel (MS) product, A36 hot-rolled angle iron balances strength and cost-effectiveness, avoiding the excessive hardness of high-alloy steels while maintaining sufficient structural performance for most general construction and manufacturing needs. It strictly adheres to ASTM A36's chemical composition requirements (maximum 0.25% carbon, 1.65% manganese, 0.04% phosphorus, 0.05% sulfur), ensuring consistent mechanical properties across every batch. Each angle iron undergoes rigorous quality inspection, including dimensional verification (leg length, thickness, angle accuracy of 90℃±0.5℃), straightness testing, and mechanical property sampling-guaranteeing compliance with international standards and reliability in real-world applications.
Whether for residential construction, industrial machinery, transportation infrastructure, or custom fabrication projects, our A36 Hot Rolled Angle Iron (25*25*2.5mm equal or unequal L profiles) delivers the precision, durability, and adaptability required to meet structural challenges. It serves as a foundational component for engineers, contractors, and manufacturers seeking a cost-effective yet high-quality mild steel solution that aligns with global standards and diverse application needs.
