Fire Rated Motorised Shutters

Cronax Fire Rated Motorised Rolling Shutters are engineered to provide maximum protection in case of fire emergencies, ensuring safety for people, property, and assets. Built with high-quality fire-resistant materials, these shutters are tested and certified to withstand high temperatures for a specified duration, acting as a barrier to flames and smoke. Designed to meet national and international fire safety standards.

Equipped with powerful motors and advanced fire detection integration, the shutters can operate automatically when linked to fire alarm systems or can be controlled manually. Their precision engineering ensures smooth and reliable performance even under emergency conditions. Constructed from galvanised steel or stainless steel with fire-rated infills, the shutters offer long-lasting durability along with robust fire resistance. Their design requires minimal maintenance, making them a dependable safety investment.
