Hot Rolled Equal Angle Steel/ Angle Far A36

Angle steel is widely used in various building structure and engineering structure, such as beam, bridges, transmission, tower, lifting transportation machinery, ship, industrial furnace, reaction tower, container frame and warehouse goods
Shelves, etc.

Material & Mechanical Properties​

Grade A36 mild carbon steel serves as the core material for this angle steel, with a carbon content ranging from 0.25% to 0.29%-a composition carefully calibrated to deliver exceptional weldability, formability, and impact resistance. Compliant with international standards such as ASTM A36/A36M, this product guarantees reliable mechanical properties: a minimum yield strength of 250 MPa, a tensile strength range of 400-550 MPa, and a minimum elongation of 20% (for specimens ≥12.7mm thick). Notably, A36 steel maintains its structural integrity even in moderately low-temperature environments (down to -10°C), making it suitable for outdoor or climate-exposed applications. Its low alloy content also minimizes the risk of brittleness during fabrication, allowing for seamless cutting, bending, and drilling without compromising structural stability.​

Structural Design, Manufacturing & Specifications​

The defining feature of this product is its equal-angle cross-section, where both legs (the two perpendicular sides of the L-shape) share the same dimensions-eliminating asymmetry and ensuring uniform stress absorption across the entire structure. The hot rolling manufacturing process further enhances its quality: by heating the steel billet to temperatures above 900°C (below its melting point) and shaping it through precision rollers, the material develops a dense, fine-grained microstructure that boosts tensile strength and fatigue resistance.​

In terms of specifications, our Hot Rolled Equal Angle Steel A36 covers a comprehensive range to meet diverse project needs:​

Leg width: 20mm to 250mm (common sizes include 40x40mm, 50x50mm, 75x75mm, 100x100mm)​

Leg thickness: 3mm to 24mm (thickness increases proportionally with leg width to maintain structural balance)​

Length: Standard lengths of 6m, 9m, and 12m; custom lengths (up to 18m) available upon request​

Dimensional tolerance: Adheres to ASTM A36M standards, with precise angle accuracy (≤±0.5°) and leg length tolerance (≤±1.5mm for legs ≤100mm) to ensure compatibility with other structural components.​

Key Advantages & Applications​

Beyond its robust material and design, this angle steel offers distinct advantages that set it apart:​

Structural efficiency: The equal-angle design ensures even weight distribution, reducing stress concentration points and enhancing overall load-bearing capacity-critical for structural frameworks.​

Fabrication flexibility: Excellent weldability (compatible with arc welding, MIG welding, and TIG welding) and formability allow for easy integration into complex assemblies, while its dimensional precision simplifies on-site installation.​

Cost-effectiveness: As a widely produced grade, A36 steel minimizes material costs without sacrificing quality, making it a budget-friendly option for large-scale projects.​

Its applications span across industries, including but not limited to:​

Construction: Building frames, roof trusses, floor joists, column bracing, and bridge components (e.g., beam supports, guardrail posts)​

Industrial manufacturing: Machinery bases, conveyor system frames, equipment supports, and storage rack structures​

Infrastructure: Highway signposts, utility pole brackets, and drainage system frames​

Fabrication: Custom metal structures, truck/trailer components, and architectural accents (e.g., decorative railings for commercial buildings)​

Quality Assurance & Surface Treatment​

To ensure uncompromising quality, every batch of our Hot Rolled Equal Angle Steel A36 undergoes rigorous quality control measures:​

Chemical composition testing: Verifies compliance with ASTM A36 standards for carbon, manganese, phosphorus, sulfur, and silicon content.​

Mechanical performance testing: Includes tensile tests, yield strength tests, and impact tests to confirm material strength and ductility.​

Dimensional inspection: Uses precision calipers and laser measurement tools to check leg width, thickness, angle accuracy, and straightness.​

Surface quality check: Inspects for defects such as cracks, pits, or unevenness-only products with smooth, blemish-free surfaces (after hot rolling) are approved for delivery.​

Optional surface treatments are also available to enhance durability:​

Hot-dip galvanization: Coats the steel with a zinc layer to provide long-term corrosion resistance (ideal for outdoor or high-humidity environments).​

Anti-rust oil coating: A cost-effective option for indoor storage or dry-environment applications, preventing surface oxidation during transportation and storage.​
