1. For different specifications of galvanized air ducts, use different thickness plates according to the specifications. On the basis of familiarizing with the size and layout of the air duct of the drawing, a skilled technician will release the material to ensure that the production and installation of the air duct meets relevant standards.
2. Dongguan spiral air pipe flange will be uniformly produced according to the series specifications specified in the drawing. In addition, the bolt holes of the flange are punched at a fixed distance using a punch and a die.
