China Long Life Span Building Material Metal Roofing Construction Using Roof Tile Stone Coated Steel

Stone coated steel roof tile is made from galvalume steel and then coated with stone chips and attached to the steel with an acrylic film. The result is a more durable roof that still retains the aesthetic advantages of high end roofing such as classical or shingle tile. Stone coated steel roof is considered by many to be the most durable and long lasting of all metal roofs, which are also energy efficient and extremely environmentally friendly.

There are 3 factors that make San-gobuild stone coated metal roof outstanding.

1. GALVALUME STEEL base

Coating composition is 55% aluminum in weight ratio (80% surface volume ratio), 43.4% zinc, and 1.6% silicon.All San-gobuild® roof products are manufactured from alu-zinc steel which have shown in tests to last 6-9 times longer than ordinary galvanised steel roofing products. This is achieved by protecting the steel core with zinc, which is itself protected by an aluminium barrier. As a pioneer of using alu-zinc steel, San-gobuild® has unrivalled experience in long lasting steel roof tile manufacture.

2. STONE CHIPS

All San-gobuild® roof tiles are coated with natural stone chips, volcanically formed and taken from quarries in French. These coatings add natural beauty to the roof and a hard layer of protection from the weather. Being of natural stone, the vibrant colour is protected against the extreme UV of the African sun and will never change.
