Steel scaffolding tube feet ground frame, chosen usually 48 mm outside diameter, wall thickness of 3.20 mm, strength grade for Q235 steel - A, the appearance of steel pipe should be flat lubrication, there should be no crack, delamination, indentation, and hard to bend and new USES of steel pipe to have factory certification.

The scaffold Before construction is necessary in steel pipe sampling, will be sent to have relevant countries talent experimental units, steel scaffolding tube bending, tensile mechanics experiments, the experimental results satisfied plan request, may use in the construction. The use of steel scaffolding tube scaffold erection of malleable fasteners, should agree with the ministry of construction "standard of steel scaffolding tube feet hand fastener" JGJ22-85 request, by a fastener production permit the produce of the manufacturers supply, can not have crack, air hole, shrinkage, sand holes and other casting defects, standard fasteners should match the steel scaffolding tube, stick and should do the whole activity sensitive parts, grip the pole when opening the ear minimum interval shall not be less than 5 mm.

Steel pipe bolt tightening torque of 70 n. m shall not be damaged. If use old fasteners, fastener necessary sample sent is about the national talent experimental unit, the fastener sliding resistance and so on experiments, the experimental results of satisfaction planning behind the request can be used in the construction.

Should be done before erection of shelves and maintenance, cleaning and consistent color, beautiful colour to environment. Scaffolding poling, guardrails, kicking pole consistent paint yellow, shear consistent paint orange. Bottom line of poling, sweep pole were painted red and white color. Scaffolding, feet hand piece choose fit on request.
