1, the product quality problems
Professional scaffolding factory is rarely in our country, many of the steel tube, fastener factory equipment humble, backward production technology, low level of technology, it is difficult to guarantee product quality. At present mostly steel pipe factory production steel pipe under the wall thickness of 3.0 mm, if the application again after years of construction, steel tube corrosion make wall thickness thinning, the steel tube will be scaffolding safety hidden trouble.

2, the construction application problems
Scaffolding and formwork support collapse is the main reason of the instability, many construction enterprises before the template construction, not for formwork design and stiffness calculation, only rely on experience to support system arrangement, the insufficient rigidity and stability of the support system to consider. Some steel tube material corrosion or wear, and the local bending or open welding, etc., make steel pipe bearing capacity drops, also support instability occur easily.

In addition, a lot of the work of the technical director without technical disclosure, the safety of the operators in detail combined with poor qualities, some workers, the construction site management confusion, not strictly in accordance with the requirements of design, installation and removal is important cause of the accident.

3, market management issues
Due to the construction and rental market chaos, lack of openness, impartiality and fair trading environment and strict quality supervision measures, many construction and leasing companies figure only cheap, ignore the quality of our products and make some good equipment, strong technology, the manufacturer of high quality benefit not protected, caused production enterprise or halt production, and many equipment primitive, backward technology of inferior low price products a lot into the construction site, bring serious security hidden danger of construction.
