China — Nowadays, the good and the bad aluminum extrued profile products are intermingled among the world market. In this case, the purchaser should gain basically knowledge about how to identify the quality of this product. Now, this article from the official blog of high quality aluminum profile supplier FOSHAN NANHAI DALI GORTAL METAL CO., LTD will uncover how to better identify the low quality products.

Extrusion defects

During the production process of the Aluminum extrusion profiles, there will be some Extrusion defects due to the faults of extrusion equipment and the improper operation process. These defects include bubbles, inclusions, layering, color, distortion and others. So, each client should carefully check whether there are many problems of their purchased products.

Thin oxide film thickness

The normally standards for architectural aluminum oxide film thickness should not be less than 10 micron. If the thickness of this part is not enough, the surface of the aluminum extruded profile will be easy to getting rusty and corrosion. These low quality products manufacturers even sell the related products with only 2 to 4um of oxide film thickness and some of their products even do not have oxide film. So, each client should firstly choose the manufacturer with high sincerity such as FOSHAN NANHAI DALI GORTAL METAL CO., LTD.

Chemical composition failed

The low quality aluminum baffle ceiling usually has incorporation of a large number of miscellaneous aluminum. Although this producing method can greatly reduce costs, it will lead to the chemical composition of aluminum construction failed which will cause into the seriously problems of building works.

Reduce the wall thickness of profiles

The national standard thickness of the 90 series aluminum profiles wall thickness should be not less than the minimum 1.4mm. However, these low quality products only own 0.6 to 0.7mm thickness.

A significant reduction in anti-corrosion process

The low quality aluminum extruded profile manufacturer finds every way they could to reduce the production cost. For example, they will reduce chemical reagent consumption to shorten the cycle of anti-corrosion process. Although this method helps to reduce the cost, it largely declines the corrosion resistance of aluminum profile.
