Benefits of chrysotile products

Printer-friendly versionSend by email

Chrysotile fibres are strong and durable. When mixed with cement to produce roof tiles and water pipes, the products are high quality and economical. Chrysotile has been used widely in Southeast Asia, including Thailand, for more than 60 years.

Chrysotile fibres have an exceptional strength and ability to be used as reinforcement material. Chrysotile has been in use in Thailand for 60 years due to its affordable cost. Over 90% of chrysotile imports to Thailand go into AC sheet and pipe production. Its exceptional strength is able to withstand the forces of nature.

  • Asbestos cement (AC) sheets are weather-proof and corrosion resistant. They are practically ageless and   maintenance free as compared to metal sheets which corrode and deteriorate with age and exposure.
  • AC sheets and pipes are corrosion and erosion-free. Once properly laid and jointed, they need no maintenance or replacement.
  • AC sheets have proven to be the most cost effective,   easy-to-install, strong and durable roofing material for warehouses, factories, low-cost housing, as well as practically any structure needing a roof.
  • Keeping in mind the challenges of a rapidly increasing population and limited resources, the manufacture of AC   products consumes low energy and does not in any way deplete natural resources.

The table below compares the characteristics of asbestos cement roofing sheets with corrugated galvanised and aluminum sheets.
