Our commercial frames are manufactured from ZN35 high tensile structural steel, weld repaired tubing, (weld repair being of molten Zinc) 44.45mm and 50.80mm diameter. Which is pre-galvanised inside and out, to provide a corrosion-free structure for many years. This means our steel tubing is almost twice as strong when compared to standard steel tube.
Its’ minimum typical mechanical values against normal materials (in brackets) are as follows:
ZN35 Minimum yield strength 350 N/mm2 (Normal steel Minimum 200N/mm2)
ZN35 Minimum Tensile strength 450 N/mm2 (Normal steel minimum 300N/mm2)
Galvanised Steel Tube
Our steel tube is sourced from UK manufacturers and every batch has full traceability. In addition, all brackets are manufactured and plated in the UK specifically for our structures. Please take a look at how our galvanised steel tube is manufactured to ensure it's unbeatable quality:
Hoop spacing is standardised at every 2 metres across the full range of our structures with cross bracing on every hoop as standard.
