Everything shall go with the trend to win a rapid development and flourish.

A standard pair of frame feet hand by two pieces of the frame body, two diagonal member, four connecting rods, a hook springboard. Frame scaffolding usage basically as interior decoration or simple exterior wall construction, optional universal wheel, moving quickly. Can be used to decorate and do support body.

Frame scaffolding the development experience for a long time.
In the early 80 s is due to the inconsistent specifications, caused a certain influence, there are some and domestic manufacturers began to generic scaffolding door, until 1985 years later, has successively established 10 scaffold factory door, door scaffold in some parts of the construction project, started a large number of popularization and application, and by the vast number of construction units welcome.

However, due to product specification is different, different quality standard , use and management bring certain difficulty to construction unit. At the same time, because of some factory adopts the material of steel pipe and specifications do not conform to the requirements of the design, door frame stiffness is small, weight is big, transportation and use of easy deformation, machining accuracy is poor, short service life, so that seriously affected the promotion of the new technology.

Finally in the 90 s, this kind of scaffolding without development, applied in the construction of less and less, instead many galvanzied door frame scaffolding factory closed or halt production, only a few processing and continue to produce good quality unit. Therefore, it is necessary to combine the construction characteristics, development of new type door scaffolding.
