The strength of the steel is not higher, the better
The strength of steel refers to the hardness of steel. The higher the value, the stronger the strength. The strength is also called the yield strength. Sometimes it is not the higher the strength, the better.Sometimes,it needs to choose different degrees of strength such as when it has stretching action, if you choose high-strength steel , it will crack.
Distinguish the difference between galvanizing and aluminized galvanizing
Light steel coating is divided into galvanized and aluminized galvanizing
Zinc plating: the amount of content, mainly depends on the value, generally using zinc 275 grams and 300 grams, the value is the content of zinc per square, the higher the content, the thicker the zinc layer.
Physical changes in galvanizing: galvanizing is exposed to oxygen in the air for a long time, and the surface will be black.
Aluminized galvanizing: referred to as AZ150, galvanized zinc is 2-6 times of galvanized anti-corrosion. The surface of the Aluminized galvanizing keel has no color change for a long time. In case of chemical corrosion, the surface reacts physically and forms an aluminum protective film on the surface of the keel. Separate the external chemical material from the keel to protect the keel body material and prevent rust.Therefore, high-quality manufacturers generally choose galvanized sheet steel.
Aluminized galvanizing steel sheet properties
1. Processability: Meet the requirements of rolling, stamping, bending and other forms of processing.
