Sky Steel Group manufactures and exports prime-grade 50×50×5mm equal angle steel bars (L-profile steel) in hot-rolled black finish and hot-dip galvanized (HDG) condition. Produced strictly to international structural standards (ASTM A36, EN 10025 S275JR / S355JR, JIS G3101 SS400, GB/T Q235B / Q355B), this standard 50mm profile offers reliable load-bearing capacity, uniform 90-degree corner geometry, and excellent weldability for global industrial construction.
Structural Strength, Precision Forming & Corrosion Protection
50×50×5mm equal angle steel is one of the most versatile structural steel sections globally, providing a high strength-to-weight ratio for frames, trusses, and bracing systems. The uniform 5.0 mm leg thickness ensures high resistance against bending moments, torsional stress, and axial compression.
Available in standard mill-finish black steel or batch hot-dip galvanized with a heavy zinc coating mass (up to 85 µm / 600 g/m² per ASTM A123 / ISO 1461), our angle steel withstands harsh atmospheric exposure, coastal humidity, and industrial chemical environments. In-house processing services include fixed-length precision cutting (5.8m / 6m / 11.8m / 12m), CNC hole punching, slotting, miter cutting, and pre-assembly marking.

Where Is 50×50×5mm Equal Angle Steel Used?
Owing to its uniform structural rigidity, standardized cross-section, and high fabrication adaptability, 50×50×5mm equal angle steel is heavily utilized in solar racking installations, multi-story industrial building frames, power transmission towers, and global containerized shipping projects.
Solar PV Mounting Structures & Ground Tracker Brackets
50×50×5mm hot-dip galvanized angle steel is widely used for diagonal bracing, column supports, and purlin connectors in utility-scale ground-mounted solar power plants. Factory CNC pre-punched holes enable fast on-site bolt assembly without welding, while the thick zinc layer provides over 25 years of corrosion-free performance in harsh outdoor soil and open-field conditions.
Industrial Steel Building Frames & Cross-Bracing Systems
In heavy-duty warehouse frameworks, workshop buildings, and mezzanine floors, 50×50×5mm angle bars serve as primary lateral cross-bracing, roof truss webbing, and girt support members. High yield strength (Q235B / Q355B / S275JR) ensures dependable structural stability against high wind uplift, seismic loads, and industrial equipment vibrations.
Standard Fixed-Length Container Loading & Sea Shipment
To maximize container payload and minimize ocean freight costs, angle steel bars are precision cut to 5.8m / 5.9m (for 20GP containers) or 11.8m (for 40GP/40HQ containers). Bundles are interlocked nest-to-nest and firmly secured with timber chocks, heavy-gauge steel straps, and container floor dunnage to eliminate transit shifting and bending deformation.
Mill Inventory Stock & Standardized Seaworthy Bundles
Produced on continuous high-speed hot-rolling mills under strict dimensional, straightness, and surface quality controls. Finished angle bars are stacked into rigid hexagonal/rectangular bundles weighing 2 to 3 tons each, tagged with detailed heat number traceability, and stored in indoor dry warehouses for rapid global dispatch.
