Grill Motorised Shutters

Cronax Grill Motorised Rolling Shutters are designed to provide security with ventilation and visibility, making them an excellent choice for commercial, industrial, and residential applications. Manufactured from high-strength steel or aluminium grills, these shutters offer robust protection while allowing natural light and airflow. The grill design ensures visibility and air circulation without compromising safety. Ideal for areas that require display and protection, such as storefronts, parking zones, and warehouses.

Equipped with reliable motors and smart controls, the shutters operate effortlessly with remote controls, push buttons, or access systems. They deliver quiet, smooth, and low-maintenance performance, even with frequent use. Constructed with galvanised or powder-coated finishes, the shutters resist rust, weather, and daily wear, ensuring long-lasting performance with minimal upkeep.
