Refined right-angle steel
Share to：
Equal and unequal angle steel, characterized by high precision, strong load-bearing capacity, and corrosion resistance, is widely used in building frameworks, machinery manufacturing, power communication, bridge engineering, and other fields, providing a stable and reliable foundation material support for steel structures and equipment manufacturing. High-precision steel sections (refined steel) are generally used in large-scale buildings with high requirements for span, transparency, aesthetics, and strength. For example, airports, high-speed railway stations, exhibition halls, theaters, large conference centers, other large public buildings, group company headquarters, five-star hotels, large assembly workshops, and various buildings with spans exceeding 60 meters.

Core Product Advantages
High-Precision Forming
Using hot-rolled or cold-bent processes to ensure edge width tolerance of ±0.5mm, edge thickness tolerance of ±0.3mm, and straightness ≤1mm/m, meeting the needs of high-precision welding and assembly.
Strong Load-Bearing Capacity
Using high-quality carbon steel and low-alloy steel materials such as Q235B and Q355B, with tensile strength ≥370MPa and yield strength ≥235MPa, providing strong support and excellent deformation resistance.
Diverse Specifications
Covering equal-angle steel (edge width 20mm-200mm) and unequal-angle steel (edge width combination 25×16mm-200×125mm), thickness 2.5mm-24mm, supporting non-standard customization.
Flexible Surface Treatment
Providing hot-dip galvanizing, painting, sandblasting, etc., improving weather resistance by 3-5 times, suitable for outdoor, humid, and industrial corrosive environments.
Application Areas
Building structures: factory trusses, steel stairs, curtain wall keel, roof support frames.
Machinery manufacturing: equipment bases, conveyor supports, heavy machinery reinforcement parts.
Power communication: transmission towers, signal base station supports, cable bridges.
Bridge engineering: bridge railings, temporary support structures, maintenance platforms.
Warehousing and logistics: rack beams, high-bay warehouse columns, loading and unloading platform reinforcement.
Technology and Quality Assurance
Strict standards: Complying with international standards such as GB/T 706, ASTM A36/A572, and JIS G3192, providing material reports and mechanical performance test data.
Precision processing: CNC cutting ensures precise angles (90°±0.5°), automatic straightening eliminates internal stress, and ensures installation flatness.
Corrosion protection testing: Galvanized layer thickness ≥80μm (GB/T 13912), salt spray test ≥720 hours without red rust, industry-leading durability.
Quick response: Constant stock of thousands of tons, supporting small batch customization and urgent orders, shortening the delivery cycle by 30%.
