300 USDA commercial steel door with an air louver is designed for commercial buildings that require airflow, moisture control, and heat ventilation, such as mechanical rooms, electrical rooms, utility rooms, and storage areas.
Made from thicker galvanized steel, this door can be fitted with a steel or aluminum louver. The louver size can be customized according to project requirements. It can be designed as a half-louver or full-louver door, with the louver placed at the bottom, top, or across the full door leaf depending on airflow, heat-control, and moisture-control needs.
For special safety requirements, smoke-proof and fireproof louvers are also available to help control the spread of smoke and fire.
