Considerations For Purchasing Aluminum Profiles

Aluminum is the aluminum bar through hot melt, extrusion, so as to obtain different cross-section of aluminum. The production process of aluminum profile mainly includes three processes: casting, extrusion and coloring. Among them, the color mainly includes: oxidation, electrophoresis coating, fluorine carbon spraying, powder spraying, grain transfer and other processes.

Here's about the selection of aluminum profiles.

First of all, in the market, poor quality aluminum profile has four major characteristics:

1, the film thickness is thin. The national standard architectural aluminum oxide film thickness should be not less than 10um (m). The thickness is not enough, the aluminum profile surface is easy to rust and corrode. Some no name and address, production license, certificate of inspection in the aluminum oxide film, the thickness of only 2 to 4um, some even without film. According to experts estimate that each reduction of 1um oxide film thickness, each ton profiles can reduce power consumption, cost more than 150 yuan.

2, the chemical composition is not qualified. The incorporation of impurities of aluminum, aluminum scrap aluminum can greatly reduce the cost, but will lead to building aluminum unqualified chemical compositions, seriously endanger the safety of construction engineering.

3, reduce the wall thickness of profiles. 90 series sliding window type, according to the national standard of the aluminum minimum wall thickness not less than 1.4mm, some products in Guangdong only 0.6 to 0.7mm. 46 series of door type, aluminum wall thickness using the national standard minimum of not less than 1.62mm, sampling, some products in Guangdong only 0.97 to 1.18mm.

4, poor quality aluminum reduction in sealing time, reducing the loss of chemical reagents, cost down, but the corrosion resistance of the profile is greatly reduced.

Attention should be paid to the selection of aluminum profile:

1, check the product ex factory certificate, pay attention to the date of production, specifications, technical conditions, the implementation of standards, business name and production license number.

2, look carefully at the surface condition of the product, the product should be bright color, good gloss, the surface can not have obvious scratches, bubbles and other defects.

3, we must pay attention to the product wall thickness, doors and windows material thickness should be no less than 1.2mm.

4, pay attention to the product surface coating thickness, oxidation products of the anodic film thickness not less than 10 m, the electrophoresis paint product film thickness not less than 17 mu m, the thickness of the coating powder coating does not exceed the 40-120 m range, fluorocarbon paint spraying products should be coated in two above, not less than 30 m.

5, users of coastal areas should have better corrosion resistance electrophoretic coating profiles, powder coating profiles or fluorocarbon spray profiles.

6, daily maintenance, can not use the brush and other hard objects as cleaning tools, should choose soft cotton yarn and cotton cloth.

7. Wash with water, soap and soap, but not with any other organic substance.
