Plain rectangular steel end caps for welding onto the open ends of rectangular box section (RHS). Plasma cut from 3, 4 or 5 mm mild steel, 304 or 316 stainless and sold in packs of 5, 10 or 25.
Need another section size or a cap with a hole? Send us a drawing.
Each size matches the outside dimensions of a common RHS section, so the cap sits flush with the outer faces ready for a fillet weld all round. Capped ends stop water getting into gate frames, trailer chassis rails, bench and table legs, and fence posts.
Made to order. We email your dispatch date. See delivery rates. Square box section? See square end caps.
Will a 60 × 40 cap fit 60 × 40 × 3 box section?
Yes. The cap matches the outside size, so it sits flush with the outer faces whatever the wall thickness.
How much does a cap weigh?
An 80 × 40 × 3 mm mild steel cap weighs about 75 g.
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.
