What are the “badness” of bad quality aluminum profile extrusions?

　　At the beginning part a manufacturer can replace good aluminum material with deserted impure material. This helps to reduce cost substantially. Once the products are put into use, they may lead to serious safety problems owing to unqualified chemical compositions. Besides, manufacturers can decrease extrusion thickness and coating thickness to reduce cost. Take window frame for example. Some aluminum profile extrusions are only 0.6mm thick, while the industry standard is no less than 1.4mm. Compared to top quality coatings of 10um, some are only 2um or with no coating at all! It’s estimated that the reduction of coating of 1um helps to reduce cost of over $20 per ton of aluminum profile extrusions. Some producers even use less chemical additives to reduce cost, which leads to great reduction of rust resistance of products.

　　Things may get more complex for exporters with problems like distance and customs procedures, thus it’s really crucial to choose a reliable supplier.
