Buying Guide

Match leg size to load requirements

Choose equal-leg dimensions (for example 1" to 3") that provide the required moment of inertia and bearing area for your support or bracket application

Consider thickness for strength

Thicknesses shown here (about 0.188" to 0.25") significantly affect bending and shear capacity—use thicker sections where higher loads or longer spans occur

Prefer A36 hot-rolled steel for general structures

A36 is a common structural-grade carbon steel with predictable mechanical properties; hot-rolled angles provide good consistency for welding and bolting

Pick length to reduce field splices

Available lengths in this group include 24", 48" and 60"; selecting a length that minimizes joints improves structural continuity and installation speed

Factor fabrication and connection needs

Account for drilling, welding, and coating requirements—hot-rolled A36 accepts standard shop practices but may need surface prep before painting or galvanizing
