The photo above  is Rip Curls retail outlet in Melbourne.  The stair stringers are 200 x 100 x 6 stainless steel RHS with 80 x 80 x 3 SHS that has the glass patch fitting fixed to it.  The glass has no top rail on the hand rail and balustrade which makes the area look very open.  The hand rail up the staircase is 31.8 x 31.8 x 1.6 SHS stainless steel tube with patch fittings to the glass.

The photo above is a hand rail that has used 50.8 diameter stainless steel tubes as the uprights and top rail.  The use of 3.2mm stainless steel wire as the run opens up the stair case, which is another option to glass.  The uprights in this type of hand rail have semi domed ends and 12mm solid bar welded to the upright.  Uprights to the ends of the hand rail are reinforced to prevent bending of the tube.  Bridco Stainless wire rope fittings and hardware is used.
