Aluminum is divided into raw aluminum and cooked aluminum. Raw aluminum is less than 98% aluminum, its characteristics of brittle hard, only sand casting products; Cooked aluminum is 98% or more aluminum, soft and can be molded or stamped into various containers. So in the case of buying aluminum profiles, how to identify fake aluminum profiles?

Characteristics of fake aluminum profile guardrail:

1, the composition is not qualified, in the product with a lot of waste aluminum, scrap aluminum cost is greatly reduced, but it will lead to the construction of aluminum components are not qualified, more serious serious harm to the construction safety.

2, the residual aluminum profile many cut off all the time, reduce the consumption of chemical drugs, the cost is reduced, but the corrosion resistance of aluminum profile is also greatly reduced.

3. The oxide film is thin and thick. The thickness of aluminum oxide film shall not be less than 10um(μm). Thin and thick insufficient, the surface of the refined aluminum profile is easy to rust, erosion. In the sample inspection, some aluminum profiles do not have the production name, production place, production license and qualification certificate, and their oxide film thickness is only 2-4um, some even do not have oxide film. According to the authoritative experts estimate that every reduction of 1um oxide film thickness, a ton of aluminum can reduce 150 diversified energy consumption costs.

4, the ingredients are unqualified. Adding a lot of waste aluminum, scrap aluminum profile can greatly reduce the cost, but will lead to the construction of aluminum profile composition is not qualified, more serious serious harm to the construction safety.

Unqualified aluminum profiles, when applied, will cause deformation of aluminum profiles because of gas, precipitation, sun and other hazards, and even produce cracks and bursts of laminated glass.
