The 50.8mm round stainless steel tube is the go-to diameter for balustrade handrails across South Africa, offering the ideal combination of structural strength and comfortable grip. At 5.8m per length, a single tube covers most standard deck or staircase sections, keeping joins to a minimum for a cleaner, more professional-looking result.
Whether you are installing a new deck balustrade, replacing an ageing handrail, or building a feature railing around a pool area, this tube forms the backbone of your project. The 50.8mm diameter is widely used by professional installers and confident DIYers alike, and is compatible with all of our pre-drilled posts, components, and fittings.

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. 1.2mm wall thickness.
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. 1.5mm wall thickness.
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.
