M1 Fire Classification Certification
The M1 Fire Classification is a recognized French fire safety standard that evaluates the flame-retardant performance of construction and architectural materials. Materials rated M1 are classified as non-flammable or hardly flammable, offering excellent resistance to fire propagation and helping improve overall safety in public, commercial, and industrial environments.
At GS TENTS, our PVC membrane fabrics comply with M1 fire classification requirements, providing reliable fire protection while maintaining high tensile strength, weather resistance, and long-term durability. This certification makes our structures suitable for exhibitions, sports facilities, warehouses, commercial events, and other applications where fire safety is a critical requirement.
