Description
Fire Resistant & Anti-Static Pulley Lagging for Underground Applications
Lag FRAS Strip Lagging is a premium-grade fire resistant and anti-static (FRAS) rubber pulley lagging, designed for use in underground and hazardous conveyor environments.
Manufactured from a specialised 65 Duro SBR rubber compound, this lagging is engineered to meet strict safety requirements while delivering reliable traction, wear resistance, and
pulley protection.
Certified for Hazardous Conveyor Environments
Independently tested and certified, Lag FRAS conforms to MDG 3608 / MDG 3006 standards, making it suitable for use in underground coal mining operations where fire resistance and
anti-static properties are critical.
SEC Business Group supplies FRAS conveyor solutions to support safe and compliant operations across mining and bulk material handling industries.
