Steel is light but strong, with good fire resistance properties. Its light weight allows you to reduce both support structure and building foundations, with valuable savings in construction costs. Light weight means that steel roofing sheets can be quickly and easily erected - saving time and money. Light weight means steel can be used over an existing roof. Inherent strength allows wide-span, thin (typically 0.7mm) sheets. Today's coated steels give long life with minimum maintenance. The versatility of steel allows a wide range of profiles and systems to give more flexible design scope and broader aesthetic appeal. Pre-painted coated steels allow you to use colour effectively - and cost-effectively.
