Exterior roof panels are usually a single continuous length from eave to ridge line for gable style buildings or from low eave to high eave on single slope or shed style buildings. Many manufacturers provide minimum 24 gauge (nominal: 0.0239 inch; 0.61 mm) thick sheet steel in self-framing roof designs.
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips.

The Concrete Reinforcing Steel Institute (CRSI) has developed standard symbols, graphics, and formats for shop drawings and cut sheets that generally are used by reinforcing steel fabricators. [5] Each fabricator, has particular style for shop drawings and cut sheets, depending on the drafts people and Computer-aided design systems.
A metal roof is a roofing system featuring metal pieces or tiles exhibiting corrosion resistance, impermeability to water, and long life. It is a component of the building envelope . The metal pieces may be a covering on a structural, non-waterproof roof, or they could be self-supporting sheets.
In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than ...
