What are the purchasing skills of aluminum alloy profiles?
Industrial aluminum can greatly reduce the cost, but it will lead to unqualified chemical composition of industrial aluminum, seriously endangering the safety of the project, so you can't choose the one that is too cheap# Aluminum#
The thickness distribution of drawings with roughly the same size, as well as the section size, width and middle hole, but the wall thickness varies greatly, and can also be quite different weights. Each price has a great difference In addition, the lower industrial aluminum can reduce some sealing time, reduce the consumption of chemical reagents, and reduce the cost, but greatly reduce the corrosion resistance of the material
Oxide film thickness - the thickness is not enough, and the aluminum surface is easy to rust and corrosion. The thickness of the oxide film of standard building and industrial aluminum should not be less than 10um (micrometer) Some attribute names, addresses, production licenses, industrial aluminum profile certificates, and film thickness of 2-4um. According to experts' estimation, the power consumption of more than 150 yuan per ton can be reduced by reducing the thickness of 1 um oxide film
Best aluminum profiles must be for Soundproof sliding door, Unitized Stick System Glass Curtain Wall&commercial kitchen doors.
