Ringlock scaffolding is a new type of nested steel tubular scaffold with self-lock function. It is composed of vertical post, ledger, horizonal ledger, base jack, etc. 

But in the recent construction cases, there are always safety accidents in the use of scaffolding, so for the manufacturers of ringlock scaffold, what quality problems need to be paid attention to?

1. Insufficient soldering, false soldering

There are serious welding defects in the quality of the ringlock scaffolding, such as insufficient penetration and unqualified welding quality. 

2. Ringlock ledger head casting defects

Due to the small casting parts and significant casting defects, compared with the investment casting process, the ledger head casting effect is poor, and a large number of shrinkage holes, pores, slag inclusion and other defects are found on the broken castings, which seriously affect the bearing capacity of the ringlock scaffold.

3. The rosette come with poor material

The weld quality of rosette and vertical post is not up to standard, which greatly weakens the joint strength.

To control the construction safety, first of all, the contractor or builder should strictly control the product quality of each batch of ringlock scaffolds, that is to say, we should cooperate with ringlock scaffold manufacturers with certain scale and good reputation. It is better to go to the factory for on-the-site investigation before ordering. This can be more objective to understand the strength of manufacturers and product quality.
