Buying Guide

Choose the right alloy

6063‑T6 aluminum is common for architectural and welding uses because it balances strength and weldability; confirm alloy grade before buying

Match leg size to your project

Equal‑leg angles like 1.5" or 2" provide predictable fit for framing and bracing—pick the leg length that aligns with mating parts and weld prep

Pick wall thickness for strength

Thickness (for example, 1/8" vs 1/4") affects stiffness and weld heat transfer; thicker walls increase load capacity but add weight and cost

Consider length and handling

Standard 4 ft bars are easy to transport and cut; plan cuts to minimize welds and joints for cleaner structural results

Check surface and finish

Architectural‑grade finishes on aluminum angles reduce prep time for cosmetic projects but may require cleaning for optimal weld quality
