Door and window aluminum profiles have been widely used in door, window, curtain wall and other building products for many years because of their small proportion, easy processing and high mechanical strength.
The higher the purity of the door and window aluminum profiles, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air to produce a thin and dense natural oxide film on the surface of aluminum, which is much faster and thicker than other metal oxide films.
Door and window aluminum profiles have high mechanical strength, and although pure aluminum has good corrosion resistance, it restricts the application of aluminum to a certain extent. Prevent harmful gases and moisture in the air to further corrode the door and window aluminum profiles, play a protective role.
Therefore, people add the right amount of magnesium, copper, other metals, such as zinc, made of various types of aluminum alloy, improve the mechanical strength of the door and window aluminum profiles, expand its application range, but its corrosion resistance is worse than pure aluminum, so it may be corroded by oxidation. A powder coating is also needed to protect the aluminum profile.
Powder coating can make door and window aluminum profiles in addition to having high corrosion resistance, but also has a variety of colors, good surface texture and many other characteristics, and a variety of colors of building exterior paint echo, door and window aluminum profiles to suit different architectural styles.
The strong properties of the door and window aluminum profiles prevent it from rotting, rusting, or bending. Low-density metals are durable in UV light and all weather conditions, with no expansion or contraction problems.
When decorating a house, color and style are usually the main factors. Plus, if you want to try out the design, you can even choose different colors on the inside and outside of the door and window aluminum profiles!
Using door and window aluminum profiles you can not only protect your house from theft and theft, but also protect the environment from non-biodegradable products. Door and window aluminum profiles are a recyclable material that can be reused.
In addition, door and window aluminum profiles are lightweight and malleable to provide your house with a high degree of wind and air tightness, thus helping to maintain good insulation.
