Knowledge of architectural aluminum profiles

Update time : 2022-09-26 10:53:12

The aluminum profile of the building also rusts, but the rust of the building profile does not always rust like iron until it is completely rusted.

Architectural aluminum profiles are materials with certain strength and toughness (such as plastic, aluminum, glass fiber, etc.), which are objects with a certain geometric shape made by rolling, extrusion, casting and other processes. The process of producing profiles by extrusion method, extrusion profiles are divided into two categories: hollow profiles and solid profiles. Architectural aluminum profiles chemically react with oxygen to form oxidized architectural aluminum profiles, which is the rusting of architectural aluminum profiles. The rust of the building aluminum profile is very thin, its thickness is only one ten thousandth of a millimeter, but it is very hard and very wear-resistant. It is close to the surface of the building profile, so that the building aluminum profile inside cannot contact the outside air, and the building aluminum profile is prohibited from rusting continuously.

Why do building profiles need surface treatment?

If the architectural aluminum profile is not surface treated, the appearance will be unsightly, and it will be easily corroded in the humid air, so it is difficult to meet the requirements of high decoration and strong weather resistance in the building materials. In order to prolong the service life, the architectural aluminum profiles must be surface treated.

Why are building profiles more expensive than iron?

Although the reserves of aluminum in the earth's crust are more than that of iron, the production process of aluminum profiles for construction is much more complicated than that of iron. Aluminum is a comparatively active metal element, and smelting requires electrolysis. The iron is high, so the price of architectural aluminum profiles is higher than that of iron.
