Mitadoor

Mitadoor is a Vietnamese brand of roller doors produced by Son Phu Thinh Industrial Co., Ltd., a company founded in 2006 and based in Bien Hoa, Dong Nai province. The company's business also includes aluminium and aluminium-glass doors. Mitadoor roller doors are sold through dealers in Vietnam for residential, commercial and industrial buildings.

In pre-engineered buildings, roller doors close large openings at loading docks, warehouses and workshops. The door is mounted on the framed opening provided by the steel building supplier: cold-formed or hot-rolled jambs carry the guide rails and transfer the wind load on the curtain to the base and to the header, and the header supports the barrel and motor. Opening width and height, curtain material, wind rating, manual or motorised operation and the clearance needed above the opening for the coil must be fixed before the framing is detailed, because they affect jamb size, girt layout and the position of canopies and gutters. For large openings or high wind speeds, the door supplier should provide the design wind rating and support reactions for the steel designer.
