Practical Notes

This material is an eco-friendly alternative to asbestos or metal sheets for low-cost housing, shelters, and agricultural buildings.

Proper handling is crucial during transport and installation to prevent cracking, as composite materials can be brittle.

Always check the manufacturer's test certificate for compliance with key performance indicators like load capacity and water absorption before procurement.
