Shelf pipe is a kind of construction and floor pipe, which is mainly used to make construction site support. It is a product rolled up by hot rolled strip after technological treatment. There are usually 91 bundles. Each length is 6 meters, is a kind of welded pipe. The material is Q235B frame tube. The execution standard is GB/T13793-2008 straight seam welded steel pipe. Distinguish according to the material of the member: 1 by the single specification steel pipe frame tube: it is using the same specification steel pipe (for example: fastener scaffolding). For example, the welded steel pipe with 48 × 3.5) note: in the field of mathematics, it means that there is no real solution (root) of the equation. 2 scaffolding composed of various specifications of steel pipe: it is composed of two or more different specifications of steel pipe combination (for example, door scaffolding) 3 all of which are mainly steel pipe scaffolding: its meaning can be understood to be that all steel pipe is mainly steel pipe. Scaffolding supported by other types of steel bars (for example, scaffolding with pedestal scaffolding or bracket with channel steel top bracket and scaffolding with fixed steel plate connection)
