Strengthening frame joints

Welded flat across the face of a joint, an L plate stiffens a corner and a T plate stiffens a mid-rail joint in box-section and flat-bar frames, gates, trailer beds, benches and racking. They also make good repair and reinforcing patches. Size is the overall length of each arm. A 200 mm L plate has two 200 mm arms, each 50 mm wide.

Choose your material

• Mild steel: the economical choice. Paint, prime or galvanise it for outdoor use.
• 304 stainless: the everyday stainless grade for indoor and sheltered outdoor use.
• 316 stainless: best near the coast, pools, salt or chemicals. 304 vs 316 explained.

Questions

Can I screw these on?
They are plain, for welding. For screw or bolt holes, send a drawing.

How much does a 200 mm L plate weigh?
About 0.41 kg in 3 mm mild steel.

Are these laser cut?
No. They are plasma cut and deburred, so edges show a plasma-cut finish and are not held to laser-cut tolerances. For tight-tolerance parts, send us a drawing.
