Product model: DC - 18 of origin: China. Guangdong. Detailed instructions, specifications, size: foshan design production according to customer's request. Second, material origin: all in Shanghai baoshan steel of high quality cold rolled A3 steel plate, national standard models for SS400 steel, the material surface, demanding. Three, pillar: use Shanghai baoshan steel of high quality cold rolling SS400 steel pipe cold drawing forming, square tube cross section size is 70 * 40 (length * width), material thickness 2.5 mm. Single force of 600 kg, to allow maximum deflection to 1/1000 of the height, safety factor of 1.5. Four, layer board: use high-quality rolling SS400 Shanghai baoshan steel material thickness 0.8 mm, the bottom of the weld reinforcement, safe and reliable. Layer board each floor carrying weight 250 kg, guide the allowed maximum deflection deformation layer board for 2/1000 of the layer board length. Safety factor of 1.5. Five, the structure: all for hooking form, free to increase or decrease in layers, the installation fast and convenient. Surface treatment: surface with acid and alkali degreasing derusting, first then phosphating antirust protection, then spraying thermosetting epoxy resin
