Matched to standard tube sizes

The sizes follow the common outside diameters of steel tube and pipe used for handrails, scaffold-type frames, gate posts and bollards. Each disc is cut to the rounded tube OD (for example a 48 mm disc for 48.3 mm tube), so it sits flush on the end ready for a fillet weld.

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

Will these fit handrail tube?
Yes. 42.4 mm and 48.3 mm are the usual handrail tube sizes, and both are listed.

How much does a disc weigh?
A 48 mm × 3 mm mild steel disc weighs about 43 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.
