Introduction
What is Aluzinc galvalume steel coil?
The galvanized sheet is composed of an aluminum-zinc alloy structure composed of 55% aluminum, 43.4% zinc, and 1.6% silicon solidified at a high temperature of 600 ° C. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal of an alloy.
Features
Excellent corrosion resistance.
good heat resistance
Good adhesion between coating and paint film
has good processing properties,
Can be punched, sheared, welded, etc.;
The surface conductivity is excellent.
The difference between galvanized sheet and Aluzinc galvalume steel coil
The biggest difference between galvanized sheet and aluzinc galvalume steel coil is the difference in the coating. The galvanized sheet surface is evenly distributed with a layer of zinc material, which plays an anodic protection role for the base metal, which plays an anodic protection role for the base metal, the alternative corrosion protection of zinc material. The base metal can be damaged only when the zinc is completely corroded.
The surface coating of the galvalume steel sheet is composed of 55% aluminum, 43.5% zinc, and a small number of other elements. The surface of the galvanized coating is a honeycomb structure at the microscopic level. The "honeycomb" composed of aluminum contains zinc. In this case, although the aluminum-zinc coating also plays the role of anodic protection, due to the less zinc content and the zinc material is not easily electrolyzed by aluminum, the role of anodic protection is significantly reduced. Therefore, once the galvalume steel sheet is cut, it will rust quickly when the cut edge is lost to be protected, so the galvalume steel sheet should be cut as little as possible. The service life of the board is extended.
Antifinger/Non-antifinger
Galvalume steel sheets can be divided into anti-finger(AFP) and Non-antifungal.
Anti-finger includes color anti-finger and colorless anti-finger.
Anti-fingerprint refers to coating a layer of anti-fingerprint liquid on the surface of a galvalume steel coil to prevent oxidation. Since human sweat and aluminized zinc are easily oxidized, a layer of anti-fingerprint liquid is applied to increase the service life of the Galvalume steel sheet.
FAQ
Q: Can we get a free sample for the test?
A: Yes. A free sample can be sent for your test. Please feel free to contact us for a sample.
Q: What's your payment term?

Q: Can we go to your factory to visit?
A： Welcome. You could come to our factory anytime when you are convenient.
Q: Can we order one container for a test?
A: For regular sizes, such as 1000mm,914mm, and 1200mm, you can order one container. The MOQ for other sizes is more because of the raw material MOQ.
But we can check if other customers need the exact sizes, and we can order together.
