Sky Steel Group manufactures and exports prime-quality 63×63×6mm equal angle steel bars (hot-rolled L-profile angle iron) in mill-finish black and hot-dip galvanized (HDG) surface conditions. Produced to rigorous international structural steel standards (ASTM A36, JIS G3101 SS400, EN 10025 S275JR / S355JR, GB/T Q235B / Q355B), this standard 63mm × 63mm section provides symmetrical cross-sectional strength, high torsional rigidity, and reliable weldability for heavy steel building fabrication, portal framing, and high-wind structural bracing.
Symmetrical Structural Rigidity, Load-Bearing Strength & Anti-Corrosion Protection
63×63×6mm equal angle steel (MS angle bar 63×6) delivers balanced moments of inertia along both principal axes ($I_x = I_y$), making it an ideal choice for multi-directional stress distributions in truss web members, column cross-ties, and purlin bracing. The true 90-degree internal angle and uniform 6.0 mm leg thickness ensure stable joint fit-up with gusset plates, standard bolts, and automated fillet welding lines.
To counter aggressive tropical humidity, high coastal salt spray, and monsoon exposure, angle bars can be supplied batch hot-dip galvanized per ASTM A123 / ISO 1461 with zinc coatings ranging from 45 µm to 85 µm (320 – 610 g/m²). Full fabrication processing includes fixed-length precision cold sawing (5.8m / 6.0m / 11.8m / 12.0m), CNC bolt-hole punching, slotted drilling, beveling, and pre-assembly marking.

Where Is 63×63×6mm Equal Angle Steel Used?
Featuring balanced section properties, high yield strength, and superior connection versatility, 63×63×6mm equal angle steel bars are widely utilized in heavy industrial pre-engineered buildings, wind-load cross bracing, equipment sub-frames, and containerized export projects.
Industrial Steel Building Frames & Diagonal Cross-Bracing
63×63×6mm angle steel is widely fabricated into diagonal knee braces, portal frame ties, and roof truss struts for industrial warehouses and commercial workshops. The symmetrical profile resists high lateral wind shear forces and seismic vibration, while pre-punched bolt holes ensure fast, accurate on-site erection.

Container Loading Operations & Protected Ocean Logistics
Angle bars are cut to fixed export lengths (5.8m for 20GP or 11.8m for 40GP/40HQ) to maximize payload efficiency (25–27 MT per container). Bundles are lifted via double-hook overhead cranes using protective nylon slings, positioned on solid timber dunnage, and firmly braced with cross-lashing to eliminate transit shifting and bending during sea voyages.

Mill Inventory Stock & Standardized Interlocked Bundles
Continuous hot-rolling lines ensure uniform 90° internal corners, clean edges, and strict dimensional tolerances (±1.0mm). Finished angle bars are interlocked in compact rectangular bundles, bound with multi-point high-tensile steel strapping, and tagged with complete heat-number identification for rapid warehouse dispatch.
