Thickness throughout the basic same specifications of engineering drawings, and its cross-sectional specifications, total width, center hole, but the difference in wall thickness is very large, but also can be very different net weight, each price also corresponds to a very big difference. In addition, the lower industrial production of aluminum can reduce some shutdown time, reduce chemical consumption, reduce cost, but the corrosion resistance of the raw material is greatly reduced.        

        Air oxide film thickness - Insufficient thickness, aluminum surface is very easy to rust, etching. The national industry standard thickness of anodized aluminum film for buildings and industrial production should not be less than 10um(μm). Some properties name, detailed address, production license, qualification industrial aluminum, plastic film thickness is 2 to 4um, some or no film. According to the doctor, every reduction of 1um air oxide film thickness, can reduce the output power consumption of one ton of composition 150 diversification.        

        How to judge the pros and cons of industrial aluminum profile is given by combing.
