Why are asbestos sheets corrugated?

Asbestos sheets are corrugated to increase their strength and durability. Corrugation involves shaping the sheets into a wavy pattern, which creates ridges and valleys that provide additional support and rigidity. The corrugations help distribute the weight of the sheets more evenly, reducing the risk of bending, cracking, or breaking. Compared to flat sheets, corrugated asbestos sheets can withstand higher loads, making them suitable for roofing, siding, and other construction applications where strength and resistance to external forces are required.
