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
