Roofing Alternative--Creating a Mission-Style Building with the Benefits and Survivability of a Metal Roof

摘要

The concept of coated steel roofing materials was developed over 50 years ago in England as a result of the British using tar and sand to camouflage galvanized bunkers from the German pilots during World War II. The original product's composition was quite different from the advancements of today as it incorporated a galvanized steel core and crushed river rock embedded in an asphalt base. Today, Metals USA Building Products, Houston, incorporates the latest technology to enhance the Gerard and Allmet stone-coated steel roofing product's performance for the rigorous and varied climates around the world. These innovations, including a weather-resistant Galvalume steel base with an ultraviolet-resistant acrylic, add superior performance characteristics. It is these characteristics that allow Metals USA to offer a lifetime warranty across the various Gerard and Allmet product lines in a wide variety of colored, granular finishes.
