Turnstar Systems manufactures a full range of manual and automatic revolving doors. The doors are installed at the entrance to buildings and provide a draft block between the internal and external environments. The draft block helps with bringing down energy costs and a revolving door also increases the flow rate of pedestrians into a building. The doors are available in a variety of sizes from 1.6m to 3.6m and also in 3 and 4 leaf configurations. The frame is manufactured either from brushed stainless steel or powder coated mild steel and the glass for the barrel and wings is toughened to ensure strength and safety.
