Corrugated and semi-corrugated asbestos cement sheets are popular construction materials made from a blend of asbestos fibers and cement, shaped into either a corrugated or semi-corrugated design. These sheets are well-known for their exceptional durability, strength, and fire-resistant properties, making them ideal for roofing and cladding in industrial, agricultural, and residential settings.

The corrugated design enhances structural integrity and facilitates efficient water drainage, making these sheets particularly suitable for areas with heavy rainfall. Semi-corrugated asbestos cement sheets strike a balance between the robust strength of fully corrugated sheets and the aesthetic appeal of flat sheets, offering versatility for various architectural designs while retaining the advantages of asbestos cement materials.

However, concerns about the health risks associated with asbestos exposure have led to increased regulations and restrictions on the use and disposal of these materials in many countries. The IS 459 standard outlines the manufacturing, chemical, and physical requirements, as well as testing methods for corrugated and semi-corrugated asbestos cement sheets.
