Stainless Steel Tubing – Round – 31mm x 5.8m

The 31mm round tube is one of the most popular choices for residential balustrade projects, sitting comfortably between the structural main rail and the slimmer infill balusters. This diameter works equally well as a handrail in its own right or as an infill baluster running horizontally between posts to create a clean, contemporary look.

Its versatility makes it a favourite for deck railings, staircase balustrades, and pool surrounds where a consistent round-tube aesthetic is desired throughout the design.

Which Grade Should I Choose?

Grade 304 is strong and reliable, suited to internal applications and external use in non-coastal, non-corrosive environments — ideal for inland areas such as Johannesburg, Pretoria, and most non-coastal suburbs.

Grade 316 (Marine Grade) offers superior corrosion resistance and is the essential choice for coastal properties, poolside installations, and any environment exposed to salt air, moisture, or chemicals. If you are in Cape Town, the Winelands, Durban, or any coastal area, Grade 316 is strongly recommended.
