Product Description
Rolled from ASTM A36 carbon steel and hot-dip galvanized to G185 standards (1.85 oz/ft⊃2; zinc coating), they provide corrosion resistance in indoor and outdoor environments. Available in leg sizes from 1×1×1/8" to 6×6×3/4", these angles offer versatile solutions for load-bearing and non-load-bearing applications.

Corrosion Protection: Galvanized coating provides 3,000+ hours of salt spray resistance (ASTM B117), suitable for coastal and industrial areas.
Load-Bearing Capacity: 3×3×1/4" angle supports 2,800 lbs per linear foot in compression (unbraced length 10'), per AISC specifications.
Formability: Can be cut, drilled, and welded without compromising galvanization integrity, facilitating on-site modifications.
Cost-Effective: Offers 70% of the corrosion resistance of stainless steel at 30% of the cost, ideal for budget-sensitive projects.
Light Frame Construction: Used as wall studs, roof rafter bracing, and floor joist hangers in residential and light commercial buildings.
Storage Systems: Forms uprights and cross-braces in warehouse racking, supporting pallet loads up to 3,000 lbs.
Utility Structures: Installed in electrical transformer frames, sign supports, and cable tray systems.
Q: What is the difference between equal and unequal angles?
A: Equal angles have identical leg lengths for symmetric loads; unequal angles (e.g., 4×3") provide greater rigidity in one direction.
Q: Can they be painted over the galvanized coating?
A: Yes, after cleaning with a vinegar solution to remove zinc oxides, use zinc-rich primer followed by compatible topcoat.
Q: What is the minimum bend radius for fabrication?
A: For 1/4" thick angles, minimum inside bend radius is 1× material thickness to avoid cracking.
