Equal Angle Spec Table

Equal Angle Specifications — 42 sizes

KS D 3502JIS G 3192

An equal-leg L-shaped angle used widely for reinforcements, brackets, and frames.

Watch for weld distortion when using as reinforcements/brackets. Thin angles distort significantly — use counter-deformation or sequenced welding.
Follow gauge line (standard hole spacing) for simple design when placing bolt holes.

Equal-leg L-shaped steel. Used for reinforcements, brackets, and frame corners. Easy to weld, readily available, and economical.

Steel truss members, brackets, frame reinforcement, shelf angles, equipment supports

How is angle size notation read?

L×L×t where L=leg length, t=thickness. E.g., L50×50×6 means 50mm legs, 6mm thick.
