Stainless Steel Tubing – Round – 25.4mm x 5.8m

The 25.4mm round tube is one of the most widely used infill diameters in stainless steel balustrade systems. Its slim profile allows multiple horizontal runs between posts to create a striking contemporary look, while its strength ensures the assembly meets safety requirements.

This diameter is particularly effective as horizontal infill balusters on deck or balcony balustrades and is also used as a handrail in its own right in applications where a lighter, more minimal aesthetic is preferred — such as internal staircases or glass-infill systems with a round top rail.

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.

Tube Rolling & Fabrication

Our tube rolling service is available in-store at our Cape Town workshop. We can roll tubing to your required radius — ideal for curved handrails, sweeping deck railings, and architectural features. Round and slotted round tubing roll cleanly in most configurations. Square, rectangular, and slotted square or rectangular profiles can also be rolled, however these shapes are more complex and results will depend on the specific radius and application required — our team will advise you before proceeding.
