RAINTITE: Flexible, Durable & Sustainable Roofing Solutions

ASD is proud to announce that OCS is now one of only two UK accredited stockholders of RAINTITE, a high-performance PVC-coated metal designed specifically for roofing and guttering applications. RAINTITE combines innovation, durability, and environmental responsibility, making it a standout solution for both residential and commercial projects.

A Closer Look at RAINTITE’s Engineering

RAINTITE is engineered to withstand extreme weather conditions, including heavy rain and ponding water, making it ideal for walkways, roofs, and guttering systems. The product’s unique anti-slip membrane pattern ensures safety and reliability in challenging environments, while its heat-weldable design significantly reduces installation time. Additionally, RAINTITE is virtually maintenance-free, offering long-term convenience and cost savings.

What sets RAINTITE apart is its innovative construction process. The product uses a unique and market-leading PVC formulation with cutting-edge material characteristics that slow down the ageing process and minimise the subsequent potential modes of failure. This advanced coating is thermally bonded to hot-dip galvanised steel, which is further protected by four layers of epoxy polyester paint, making RAINTITE a flexible, high-performance product with exceptional longevity and resilience.
