ALUMINUM AUTOMATIC SMOKE VENT
Triangle design effectively prevents water accumulation on the surface of skylights. Aluminum alloy frames can be designed as single or split according to the structural characteristics of the building roof. The surface is anodized and has good corrosion resistance.
Aluminum Automatic Smoke Vents are economical and widely used in the lighting, ventilation, and smoke exhaust needs of various building roofs.
1.Use 2mm hot-dip galvanized steel plate to weld and form as a whole, spray paint the welded areas, and use the natural color of the galvanized steel plate for the unwelded areas
2.Use 3mm aluminum alloy for overall welding and shaping, spray paint treatment on the welding area, and the unwelded area is the natural color of galvanized steel plate
