Light steel keel line

Metal frame, is a steel and wood, construction materials earthquake fire. Metal frame of high quality cold-rolled galvanized steel coil as raw material, rolling through a kind of decorative material, which material uniformity, high strength, steel degree of good corrosion resistance. Done in conjunction with gypsum board walls, suspended ceiling with the best materials. Name: HF50 Main and metal frame production line program 1. Rolling sheet metal thickness: = 1.2 mm. Second, the production line is mainly composed by: 1. Uncoiled - 2 sets 2. Forming the host - 2 sets 3. Hydraulic cutting system - 2 sets 4.4 sets of care rack 5.2 sets of control systems. Third, the production line is mainly composed of structural description: 1. Uncoiler: Single-support machine, manual open-book, screw concentric swelling structure. 1) maximum load: 3t. 2) the mandrel base diameter: set by the user. 2. Incision and cut off the hydraulic system: This machine is driven shear cylinder mold to achieve the effect of incision and cut off.
