1. Scaffolding Material
When purchasing socket-and-spigot interlocking scaffolding, first understand the material used to determine whether it is made of standard primary steel pipe. Many unscrupulous small workshops use a mixture of primary and secondary steel pipe to lower the market price. The use of secondary steel pipe poses numerous safety risks and can cause cracking during construction, so the material is crucial.
2. Scaffolding Water Absorption
The lower the water absorption rate of the socket-and-spigot interlocking scaffolding, the better. Testing is simple: first, measure the weight of a dry piece of socket-and-spigot interlocking scaffolding. Then, place the piece in water for a period of time, remove it, and weigh it. Compare the difference in weight, which represents the weight of the water. If the water absorption rate exceeds the national standard of 12.0%, the scaffolding definitely does not meet the standard and is a quality issue.
3. Scaffolding Glaze
It is common for the glaze of socket-and-socket scaffolding to crack. This cracked glaze will fall off during winter ice formations, causing the scaffolding to lose its original gloss and waterproof properties. To inspect this, simply check for fine, spider-web-like cracks on the surface.
4. Scaffolding Sintering Degree
The higher the sintering degree of socket-and-socket scaffolding, the stronger it is. This can be verified by tapping on it; the clearer the sound, the better the quality. The national standard for flexural strength is ≥1020N.
