Corrosion and Rust Resistance: The main advantage of galvanized steel coil is its good corrosion and rust resistance. The iron in steel is a very active chemical and is prone to rust. However, the addition of zinc acts as a protection and buffer between the steel and moisture or oxygen. Therefore, the zinc coating acts as a barrier against external aggression and will sacrifice itself to protect the steel underneath.

Lifespan: In the case of galvanizing, the lifespan of GI coils in working environments is well over 50 years, and can last for more than 20 years under severe water exposure. Cost: First of all, the overall cost of galvanizing is lower compared to other coatings. In addition, galvanized steel coils are ready for use after delivery. It does not require additional surface treatment, inspection, painting or coating.

Durable and Reliable: Hot-rolled or cold-rolled coils are often used as the substrate for galvanized steel. The steel is strong and the zinc coating is strong and durable.

Complete Protection: Every inch of the galvanized steel coil is protected, including grooves, sharp edges and hard-to-reach areas, making it less susceptible to damage. Easy to inspect: The simple design of the product structure makes it easy to evaluate with the naked eye and use simple non-destructive thickness testing methods.

Carbon steel is actually iron. "Iron" is a name relative to other types, used to distinguish copper, aluminum, lead, etc. In fact, iron is steel. In the past, traditional sayings generally divided iron into "pig iron" and "wrought iron". Pig iron is called iron, and wrought iron is called steel. "Carbon steel" is a classification of steel, which is divided into two categories: "carbon steel" and "alloy steel".

Cold-rolled steel is low-carbon hot-rolled steel that has been rolled at room temperature, below its recrystallization temperature. The steel is then cleaned of oxide scale and finished in a specific series of rolling to just over the desired thickness, heating to controlled temperatures, and final rolling to the desired thickness. This produces steel with a close thickness tolerance (+/-.0015” or better) and a wide range of controlled surface finishes. The process of cold rolling increasing the steel’s strength and hardness, while decreasing its ductility. Not only can you achieve improved mechanical properties, cold rolling provides more control over the shape and final dimensions of the product.
