Buying Guide

Choose the right alloy

6063 aluminum is common for structural angles offering good extrusion quality and corrosion resistance for general framing

Match leg size to load

Wider legs (e.g., 3") increase bending stiffness while narrower legs save weight; pick dimensions that suit your span and load

Consider thickness for strength

Thicker gauges (1/4" or 3mm) provide higher shear and bending capacity for supports and brackets

Length and easy trimming

Standard 48" lengths are convenient for many projects and can be cut for custom runs; long straight pieces reduce joints

Look for finish and tubing compatibility

Mill or anodized finishes affect corrosion performance and appearance; verify compatibility with fasteners and mating profiles
