Stainless Steel Roofing
Background Information On Stainless Steel
Stainless steel is a man-made alloy of Steel with 11% of Chromium. Stainless steel has been used as a roofing material since the early 1900’s in America, but has only become popular in the UK over the last 40 years. At first all of the stainless steel used for roofs was known as ‘bright’. This bright material kept its shiny lustre and there are roofs which are as bright today as they were when installed 90 years ago in America.
Then in the 1960’s a new system was developed that bonded a surface layer of lead onto the top surface of the bright stainless steel. These days the lead has been replaced by a layer of tin. The result was Terne Coated Stainless Steel, enabling the stainless steel to produce a surface finish the colour of lead.
Today the manufacturers of stainless steel produce a product with many surface finishes ranging from low reflective to mirror finish along with a product which is suitable within a marine environment.
Stainless steel is extremely resistant to atmospheric pollutants. When in contact with other materials stainless steel will not be eroded by timber treatment products, or those with a high bituminous content, cement and lime mortar or any type of timber including Cedar and Oak.
