Flat steel rings (annular plates) plasma cut from 3, 4 or 5 mm mild steel, 304 or 316 stainless. Choose the outside diameter and a 25 mm or 50 mm wide band. Buy them singly or in packs of 5.
Need bolt holes, a different band width or a bigger ring? Send us a drawing.
Flat rings are welded on as stiffening rings and collars on tube and tanks, used as reinforcing pads round pipe penetrations, as frames for round tabletops, mirrors and planters, and as fire pit and chiminea rims. The hole size is shown in each option, for example a 300 mm ring with a 50 mm band has a 200 mm hole.
Made to order. We email your dispatch date. See delivery rates. Need solid discs instead? See circular metal plate.
How accurate is the hole size?
The ring is plasma cut in one run, inside and outside, so it is concentric. Allow for a plasma-cut edge rather than a machined fit.
How much does a ring weigh?
A 300 mm ring with a 50 mm band in 3 mm mild steel weighs about 0.9 kg.
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.
