Plywood sheet siding is sometimes used on inexpensive buildings, sometimes with grooves to imitate vertical shiplap siding. One example of such grooved plywood siding is the type called Texture 1–11, T1-11 , or T111 ("tee-one-eleven").
Industrial buildings are often built with and covered by trapezoidal sheet metal. [7] Many materials today undergo the corrugation process. The most common materials for corrugated iron are ferrous alloys (e.g. stainless steels), aluminium and copper. Regular ferrous alloys are the most common due to price and availability.
Metal roofs are 100% recyclable and can be made from other recycled products. Asphalt shingles are petroleum based with other chemicals making their recycling process more toxic, most shingles are not recycled and 20 billion pounds (9.1 million tonnes) are sent to landfills every year and take hundreds of years to decompose.
The use of cold-formed steel members in building construction began in the 1850s in both the United States and Great Britain. In the 1920s and 1930s, acceptance of cold-formed steel as a construction material was still limited because there was no adequate design standard and limited information on material use in building codes.
Aluminium is widely used in sheet metal form due to its flexibility, wide range of options, cost effectiveness, and other properties. [6] The four most common aluminium grades available as sheet metal are 1100-H14, 3003-H14, 5052-H32, and 6061-T6.
When used as siding boards, widths between 130mm and 300mm (5.25 inch to 12 inch) are available. [4] Fiber cement thicknesses vary between 4.5-18mm and also vary in density – the lower density resulting in a fibrous rough edge when cut and the higher density having a cleaner smoother edge when cut.
Pre-manufactured roof trusses come in a wide variety of styles. They are designed by the manufacturer for each specific building. Timber trusses also are built in a variety of styles using wood or metal joints. Heavy timber rafters typically spaced 240 cm (8 ft) to 370 cm (12 ft) apart are called principal rafters.
Plastic shed kits utilising heavy moulded plastics such as PVC and polyethylene may be less expensive than sheet-metal sheds. PVC resins and high-impact, UV light -resistant polyethylene make plastic outdoor sheds stronger, lighter, more durable, and more resistant to denting and chipping than wood, and tend to be more stable.
