1. Material
When purchasing scaffolding, the first step is to inquire with the supplier about whether it is made from high-strength steel. Some smaller workshops may lower prices by mixing first and second-grade steel pipes, which can lead to safety hazards as secondary steel pipes are more prone to bulging and cracking on construction sites. Thus, selecting scaffolding based on its material is crucial.
2. Appearance
The quality of appearance primarily hinges on factors such as glaze color uniformity, flatness, surface shine, smoothness, degree of backside sintering, and brand markings.
3. Water Absorption
Lower water absorption rates indicate better quality since high absorption can lead to poor freeze resistance. To test this property, compare the weight difference between a dry scaffold and one that has been wet; this reflects moisture content. According to national standards, water absorption should be 12% or less—failure to meet this standard suggests potential quality issues.
4. Glaze Cracks
Cracking in the glaze of traditional scaffolding is quite common. If glazed scaffolds develop cracks during winter freezing conditions, they risk losing their waterproof capabilities and luster due to peeling layers. Inspect for small cracks on the scaffold's surface; these become more apparent when exposed to rain or dust accumulation.
5. Sintering Degree
A higher sintering degree indicates a stronger scaffold structure. You can assess this by tapping it lightly; a clearer metallic sound signifies better quality scaffolding. The national standard requires bending strength of at least 1020N—if this benchmark isn't met, there could be underlying quality concerns. Additionally, consider working with larger manufacturers known for their reputation in producing reliable scaffolding products.
