How to buy aluminum alloy building profiles?

The level and type of aluminum alloy building profile products produced in my country are comparable to those of foreign countries. The types of aluminum alloy building profiles can be divided into: anodized colored profiles, electrophoretic painted profiles, powder sprayed profiles, fluorocarbon paint sprayed profiles and heat insulation profiles, etc.   aluminum alloy building profile products have the advantages of high strength, light weight, corrosion resistance, good decoration, long service life and rich colors. Generally, the surface of a good product will not lose its gloss and color within 20 years.   Precautions for purchasing aluminum alloy construction profiles:    Precautions for purchasing and using aluminum alloy construction profiles:    1. Check the product delivery certificate, pay attention to the delivery date, specifications, technical conditions, enterprise name and production license number.  2. Observe the surface condition of the product carefully. The product should be bright in color and good in luster. The surface should not have obvious scratches, bubbles and other defects.  3. Be sure to pay attention to the wall thickness of the product. The product thickness of the door and window materials should not be less than 1.0mm. 4. Pay attention to the thickness of the surface coating of the product. The film thickness of anodized products is not less than 10μm, the film thickness of electrophoretic paint products is not less than 17μm, and the thickness of powder spray coating does not exceed the range of 40-120μm. Fluorocarbon paint spraying The product should be above the second coating and not less than 30μm.  5. It is best for users in coastal areas to choose electrophoretic paint profiles, powder spray profiles or fluorocarbon spray profiles with better corrosion resistance.  6. u200bu200bBrushes and other hard objects cannot be used as cleaning tools during routine maintenance. Soft cotton yarn and cotton cloth should be selected.  7. Water, detergent and soap can be used for cleaning, but other organic substances cannot be used. Inferior quality characteristics of aluminum alloy construction profiles:   Extrusion defects: due to the completeness of the extrusion equipment, the maturity of the extrusion process, and the improper operation during the extrusion of aluminum profiles, defects such as bubbles, inclusions, layering, color difference, distortion, etc. will occur , Affect the quality of aluminum profiles.   Thin oxide film thickness: National standards stipulate that the oxide film thickness of architectural aluminum profiles should not be less than 10um (micrometers). If the thickness is not enough, the surface of aluminum profile is easy to rust and corrode. In the random inspection, some aluminum profiles without production name, factory location, production license, and qualification certificate have an oxide film thickness of only 2 to 4um, and some do not even have an oxide film. According to experts' estimates, for every reduction of 1um oxide film thickness, each ton of profile can reduce the cost of electricity consumption by more than 150 yuan.  Unqualified chemical composition: Aluminum profiles mixed with a large amount of miscellaneous aluminum and scrap aluminum can greatly reduce costs, but will lead to unqualified building aluminum profiles and seriously endanger the safety of construction projects.   Reducing the wall thickness of the profile: For the 90 series sliding window type, the minimum wall thickness of the aluminum profile is not less than 1.4mm according to national standards, and some products are only 0.6 to 0.7mm. For 46 series of floor bomb doors, the minimum wall thickness of the aluminum profile used in the national standard is not less than 1.62mm. During the random inspection, some products are only 0.97 to 1.18mm.   Inferior aluminum profiles greatly reduce the sealing time, reduce the loss of chemical reagents, and reduce the cost, but the corrosion resistance of the profiles is also greatly reduced.
Professional aluminum window profile manufacturers also understand that when you're working with aluminum extrusion rail product, it's important to understand that quality of custom aluminium extrusion always matters.
