Asbestos cement corrugated sheet: Asbestos cement is a hardened mixture of asbestos fibers, portland cement, and water. Fibrous cement created an easy and affordable alternative to corrugated metal panels, which offer little insulation and inevitably rust over time. Corrugated asbestos sheets were used in the roofing and siding of all types of buildings, especially in factories and farms. 
According to IS 13008: 1990, The overall width of asbestos cement corrugated sheet is 1.05 meter (-5 to + 10 mm tolerance).
