Beds: As the name suggests, high and low beds. The most common level of each bed can all live in one person, the entire bed is divided into four columns, two bed drawer, two bed board, and some component parts. Each bed safety performance reflected mainly in the thickness of the stent, quality mattress and welding firm of the production process. 1 bunk bed production process, specification: W2000 * D900 * H1750mm 2, welding part of the high standard fusion welding, smooth surface; 3, bedstead by automatic degreasing, electrostatic spray, after a rigorous nine-bit processing. Pure water cleaning, heating oil phosphate, table transfer, drying process, so rust resistance and longer life. Incase pure color, soft, feel extraordinary. 4, using automatic spraying line, surface electrostatic powder spray (manual and automatic spraying line combination, coating uniformity, strong adhesion), the use of environment-friendly counter international brand is ROHS compliant Akzo powder, electrostatic spray plastic, so that the real environmental non-toxic products. 5, bed frame and mattress rigorous force switch test, in line with the national standard. Material Introduction 1, bed penstock: Product 40mm * 40mm * 1.5mm square tube welded steel pipe. 2, the security fence: 1400mm * 250mm, Φ19 * 1.5mm tube, directly fixed to the periphery of the left fence risers to enhance strength. 3, laying frame using 30mm * 50mm * 1.5mm square tube welded steel pipe. 4, escalators: The pipe Φ25mm * 1.5mm, Φ19mm * 1.5mm tube, specification 260mm * 1250mm, total fourth gear, with a wear-resistant plastic cover, with glue fixed 5, beds plate: fir 1900mm * 70mm * 18mm * 12, the end of file 900mm * 40mm * 30mm * 7 root test bed plate should be able punching (punching body weight of 25kg, the impact of high 140mm, 10 times, no loose deformation) 6, iron fasteners should be used spring washers, steel part of the carbon dioxide shielded welding, surface electrostatic powder spray, color gray, 70% more than the finish, hardness of 0.4, punching power 4N / M. Development of bunk bed is a rise in recent years for students and other groups use the bed, wide application, bunk beds for the use of space and is generally used. Equivalent to more than the single bed position a bed. For stays of students, on the bed effectively save space, a good solution to the problem of inadequate school buildings.
