( Eight) Layer of protection between the pick operation layer and the underlying application qualified safety net or take other measures to block enclosed protection. ( 9) Scaffold material 1, steel tube scaffold should choose 48 mm outside diameter, wall thickness. 3. 5 mm of A3 steel, surface should be smooth, no rust, crack, delamination, indentation, and hard to bend and new steel pipe factory certificate. Should be done before erection of shelf maintenance, cleaning uniform color, beautiful color to the environment. 2, in this engineering scaffolds were more than 25 m, less than 50 m, need to use in line with national standards of qualified steel pipe and fasteners, fastener shall comply with the requirements of steel pipe scaffold standard issued by the ministry of construction, a fastener production license, specifications and steel pipe matching, using malleable cast iron, can not have crack, air hole, shrinkage, sand holes, such as forging deficiency, and should level off, flexible activity place, grip the pole when opening the minimum distance of not less than 5 mm. Steel fasteners the field sampling inspection qualified can be put into use. 3, steel shapes appropriate USES A3 channels or beams. Insulation scaffold dimensions
