Steel coil is finished steel sheet or strip that has been coiled or wound after rolling with the width of the metal sheet being greater than its thickness. Steel coil with certain coatings can be weather-resistant, protect against moisture, and is ecofriendly. Steel coil is produced through different processes depending on the desired outcome.
- Hot-rolled steel coil is steel plate that is rolled at a high temperature, making the steel easier to manipulate. Due to the quick and easy process, hot-rolled steel saves time and is less expensive to manufacture.
- Cold-rolled steel coil has a nicer finish and is more durable than hot-rolled steel. Cold-rolling is a process where the steel is rolled at room temperature, below its recrystallization temperature. While cold-rolled steel coil is more superior to other coils, cold-rolled steel can be harder to manipulate due to the higher carbon content.
- Galvanized steel coil is created through a hot-dipped process that dips the metal into zinc for a nice smooth coating. The coating creates a strong rust resistance and prolongs the life of the steel coils.
- Galvannealed steel coil is created similar to galvanized steel through a hot-dipping process that soaks the metal into a liquid bath of zin alloy and then is passed through in-line heat treatment. Galvannealed steel is usually thinner and is more assessable to painting compared to other processes.
