Aluminium Profile For Cabinet Frame
What are the advantages of Xin-alu aluminum profile for cabinet Frame
1. Waterproof
The aluminum profile of the cabinet door is made of aluminum alloy frame inlaid with crystal steel plate. The aluminum alloy profile, ABS plastic parts and crystal steel plate are bubble resistant materials. Therefore, the aluminum profile of the cabinet door provides 50 years of waterproof guarantee, which can be directly washed and soaked with water.
2. Fire prevention
The aluminum profile of cabinet door has strong heat resistance. The test shows that it can withstand the temperature difference of 200 ℃ without damage. Even if the whole piece is placed on it after being ignited, its surface will not be damaged after burning for a long time, which overcomes the disadvantage that ordinary plates can not stand burning.
3. Insect and ant prevention
The aluminum profile of the cabinet door is extremely hard, and even termites have nothing to do.
4. Impact resistance
The aluminum profile of cabinet door has strong impact resistance. The experiment shows that it can withstand the test of 227g steel ball falling from 3m without damage, and the bending strength is 150MPa.
5. Wear resistance
The surface of aluminum profile of cabinet door is not damaged by knife cutting. It can be used under normal conditions for 50 years.
