Thin oxide film thickness.The national standard stipulates that the oxidation film thickness of building aluminum profiles should be no less than 10um(micron).The thickness is not enough,the surface of aluminum profile is easy to rust,corrosion.Sampling in some of the name,site,production license,certificate of aluminum profile,its oxide film thickness is only 2 to 4um,some even without oxide film.It is estimated by experts that every 1um of oxidation film thickness reduced,each ton of profile can reduce the cost of power consumption more than 150 yuan.

The chemical composition is not up to standard.Adding a lot of miscellaneous aluminum,waste aluminum can greatly reduce the cost of aluminum profiles,but it will lead to unqualified chemical composition of building aluminum profiles,seriously endanger the safety of building projects.

Reduce section wall thickness.90 series push-pull window type,according to the national standard its aluminum profile wall thickness minimum not less than 1.4mm,some Guangdong products only 0.6 to 0.7 mm.The minimum thickness of aluminum profiles used in national standards is no less than 1.62mm.In random inspection,some products in Guangdong are only 0.97 to 1.18mm.

Low quality aluminum profile greatly reduces the closing time,reduces the loss of chemical reagent,reduces the cost,but also greatly reduces the corrosion resistance of the profile.
