Stainless Steel Handrail Tube for Glass Railing System Round and Square Handrail Pipe

Both. Round rail is supplied in the usual 42.4 mm and 50 mm sizes, and square rail in 40x40 or 50x50 mm, all in 304 or 316 stainless with 1.5-2.0 mm wall. The two profiles use different connectors and clamps, so decide the section first - round is the common handrail choice, square suits a more architectural look.

Yes, for both sections we supply 90-degree elbows, 45 and 135-degree corner bends, end caps, wall flanges and the tube connectors used between straight runs, plus glass-to-rail clamps that fit each profile. Ordering tube and fittings in one batch keeps the OD and finish matching - mixing suppliers usually shows at the joints.

Yes, both sections are available in 316 as well as 304. For a seafront balcony, specify 316 throughout - tube, bends and fittings - because 316 resists the chloride pitting that starts where salt spray and rain collect in the tube ends and floor sockets. If the frame is already 304, keep the rail metal consistent at every joint.

We cut to your exact dimensions and allow for the socket overlap on connectors, so no on-site cutting is needed for a standard layout. For welded systems, add 5-8 mm per weld joint for grinding loss - we can pre-cut with that allowance if you send the joint schedule. Custom-color runs need the 500 pc minimum; plain cut lengths start at 50 pcs.

We design around the common code requirements - a concentrated load of 0.5 kN at any point and a distributed load of 0.36 kN/m. With 2.0 mm wall and posts spaced up to 1200 mm, a 42.4 mm round tube stays within that envelope. If your project code is stricter, send the figure and we recommend a heavier wall or closer post spacing.
