For production of hot-dip galvanized steel coil, steel-based composites and cold-roll steel sheets are immersed into melted zinc heated to 470 degrees, effectively coating the sheet in zinc. The zinc coating provides corrosion protection. As a result, the service life is greatly extended. The product also features high strength, impact resistance, bending resistance, compression resistance, aging resistance and deformation resistance.
The thickness ranges from 0.12 to 1.2mm, while the width ranges from 750 to 1,250mm. Depending on the coating weight, the hot-dip galvanized steel coil is divided into soft and hard types. Complying with G550 standards, the hard type has a hardness greater than HRB85. We recommend the appropriate steel coil for our customers based on their requirements for thickness, width, coating weight, coating type and usage environment. Due to restrictions imposed by raw material and production costs, our minimum order quantity is 50 tons.
Our hot-dip galvanized steel coil is suitable for many applications. It can work as floor support plate and pre-painted base metal or be used for the construction of barns, air ducts and household appliances shells. It is often found in many areas, including construction, household appliance production, and vehicle and vessel manufacturing.

Production Line The production line is equipped with a cleaning procedure for removing greasy dirt and iron powder attached to the strip steel. Degreasing efficiency is significantly improved through a combination of chemical degreasing and electrolytic degreasing. In the production line, other processes are also included such as annealing, deoxidation, galvanizing, finishing and tension leveling.
Testing Room Every steel reel is carefully tested in terms of compositions, strength and hardness. We also keep records of this information, which enables us to track and correct quality issues.
Packaging Four people are assigned for the packaging of the finished product, which is wrapped with waterproof paper first and then with iron sheet. Finally, an arc structure will be installed inside of the steel coil for preserving shape. It takes about 10 minutes to package one piece of finished product.

Precautions 1. The product should be kept in a well-ventilated dry room, not in the open air since it is difficult to control outdoor temperature differences. Large temperature differences could easily cause moisture condensation to damage the coil. 2. The ground of the storage area should be as flat as possible and hard objects should be also removed. The ground should have a large bearing capacity. 3. Generally, stacking storage should be avoided to prevent damage. In circumstances where stacking storage is applied for some reasons, the number of stacking layers should be strictly controlled and steel coil with heavy weight and large dimensions should be placed at the bottom. 4. Protect the coils from moisture. 5. We do not recommend storage of large quantities of the steel coil in environment rich in sulfur dioxide, and steel coil which has already been exposed to such an environment, should be moved as soon as possible.
