All materials are selected to provide reliable performance, low maintenance requirements, and long service life in a wide range of operational and environmental conditions.
| PVC cladding | High-strength PVC-coated polyester fabric, tensioned over the structure to create a durable, weatherproof building envelope. The membrane is waterproof, UV-resistant, flame-retardant, and designed for long service life in demanding environments. |
| Steel components | Hot-dip galvanised structural steel framework manufactured to engineered design specifications. The zinc coating provides long-term corrosion protection, making it suitable for exposed, industrial, and coastal environments. |
| Aluminium components | High-strength 6082 aluminium with a self-colour anodised finish, offering an excellent combination of strength, corrosion resistance, low weight, and minimal maintenance requirements. |
Renthall structures are clad with a high-strength PVC-coated polyester fabric designed for long-term use in demanding environments. The membrane is tensioned over the structure to create a durable, weatherproof building envelope.
The fabric is tested in accordance with BS 3424 for tensile strength, elongation, tearing strength, bursting strength, coating adhesion, and resistance to flexing. These tests help ensure long-term durability and performance in challenging operating conditions.
Yes. The PVC fabric is flame-retardant and self-extinguishing, tested to BS 5438 Test 2B.
Yes. The PVC membrane and sealed overlap joints provide a fully weatherproof covering designed to withstand demanding weather conditions and wind loading.
Hot-dip galvanising is a corrosion protection process in which steel components are immersed in molten zinc. The zinc becomes metallurgically bonded to the steel surface, creating a durable protective layer that forms part of the steel itself rather than simply coating it.
Structural steelwork is hot-dip galvanised to BS EN ISO 1461. A minimum coating thickness of 85μm is typically specified for C3 environmental conditions, with enhanced protection available for more corrosive locations where required.
Yes. Renthall structures are engineered for demanding industrial, commercial, coastal, and marine environments. Durable PVC cladding, hot-dip galvanised steel, and anodised aluminium components provide excellent strength, weather resistance, and long-term performance.
