1, look at the scaffold appearance
Basically see the consistency of glaze color appearance, roughness, surface gloss, smooth degree, the degree of sintering, on the back label trademark, etc.

2, the crack glaze
Scaffolding crack glaze is a common phenomenon. Crack glaze layer stripping off will be shown after the scaffold in the winter cold, and thus lose luster and waterproof performance. Check method is to look at the scaffold surface crack of fine as silk. After the heavy rain or flooding sticky dust more obvious.

3, see water absorption
Scaffolding suction less is better. Water absorption amount of antifreeze performance is poor. Check method is relatively dry scaffolding and soggy scaffolding weight difference, is the water. National standard regulations, bibulous rate is 12.0% or less, the factory scaffolding the bibulous rate of 3-5%, antifreeze performance is fine.

4, comparative degree of sintering
The higher the degree of sintering of scaffolding, the more firmly. Method is to hear the sound of tapping, more metal sound when knock is ringing the scaffold, the better. National standard of the flexural strength of 1020 n, or our factory flexural strength of 7280 n (on average).

Buy what items the scaffold mainly pay attention to the choose?
1. To see whether the steel tube pole is level, a lot of small workshop manufacturer is a mixture of primary pipe and secondary steel pipe, in order to depress the market price, but the secondary steel pipe in the construction site to cause safety accidents of engineering the drum cracking.
