How can I know whether the quality of aluminum profile is good or bad? WJW Aluminum Supplier teaches everyone.
The quality of aluminum profiles is good. The main depends on the ingredients. Let's take a closer look.
Is the quality of aluminum profiles good or bad? The way of distinguishing is as follows:
1. The thickness of the air oxide film is thin and thinner. The national industry standard requires that the air oxidation film of the engineering building aluminum profile should not be less than 10 m (micron). Insufficient thickness, the surface layer of the aluminum material is easy to etch and corrodes. In the sampling test, some aluminum profiles do not have production names, production manufacturing, production licenses, and qualification certificates. Their air oxide film is only 2 4um, and some even have no air oxidation film. It is understood that every time the air oxidation film is reduced by 1 m, the cost of energy consumption of one ton of aluminum can be reduced by more than 150 yuan.
2. But the ingredients.
Mixing aluminum profiles with many aluminum and scrap steel can greatly reduce cost fees, but it will cause the composition of aluminum profiles in engineering construction to be unattractive and seriously harm the safety of engineering buildings 3. Thin aluminum -type wall thickness. The 90 series of mobile doors and windows and window aluminum profile products shall not be less than one-four mm according to the standard of international profile standards, and some products are only 0.6-0.7mm in Guangdong.
The 46 series of product ground reeds, the national industry standards are not less than 1.62mm in the wall thickness of aluminum materials, sampling checks, some products are only 0.97-1.18mm4 in Guangdong. Pseudo-inferior aluminum profiles greatly reduce the closed time, chemical consumption and loss The cost fee is reduced, but the corrosion resistance of aluminum profiles has also been greatly reduced.
The quality of aluminum profile is a good or bad way to discriminate. It has been introduced above. WJW Aluminum Supplier provides a large number of professional knowledge on the purchase and maintenance of aluminum profiles.
