Steel Coil - Overview
A steel coil is a continuous length of steel that has been rolled into a cylindrical shape. It's a versatile form of steel used in various industries for manufacturing diverse products. Steel coils are produced by rolling steel ingots or slabs into flat sheets and then coiling them for convenient handling and storage.

Types of Steel Coil
Hot Rolled Steel Coil
Hot rolled steel coil is one of the most common types of steel coil.
Features: Usually, the color of hot-rolled steel coils delivered is black, gray or blue-black, etc., with rough surface and not very beautiful.
Cold Rolled Steel Coil
This steel coil type is one of the most widely used steel materials, and it is also one of the steel coil types that our Songshun Steel exports the most.
Features: Cold-rolled steel coils are usually silver-white, with a smooth, flat, clean surface, sharp edges and corners, and good aesthetics.
Galvanized Steel Coil
The galvanized steel coil type is one of the most widely available steel products on the market.
Features: The surface of the steel coil is plated with a layer of zinc. The surface is smooth, usually showing a bright silvery white color, and has good aesthetics.
Color Coated Steel Coil
This steel coil type is available on the market in a variety of different color patterns and with special surface treatments.
Features: The surface of the color-coated steel coil is coated with a layer of color paint, which presents rich colors, smooth surface, and good aesthetics.
Stainless Steel Coil
The stainless steel coil type is a finished coil made of stainless steel plates.
Features: The stainless steel coil has a smooth surface, excellent quality, good brightness and no oxide scale, etc.
Application
01/
Pipe-Manufacturing
The most common use for steel coils can be found in pipe manufacturing. Pipes such as ERW (Electronic Resistance Welding) and seamless pipes begin with an uncoiled sheet of metal that passes through a continuously rolling machine. The aim of this method is to fuse the two joints of the rolling process through ERW without using any welding filler compound. As ERW pipes do not depend on heat furnaces or high-temperature, it's classified under cold-forming pipe manufacturing which reduces internal stresses of the pipe, whether during storage or in use.
02/
Structural Steel Members
In applications wherein high tolerances are not necessarily required, steel coils are preferred. This is due to the high weld-ability, ductility, and machinability of the steel sheets when they're unwound. Using any type of metal fabrication machine, press breaks, or stamping machine, steel coils can be transformed into exceptional structural steel members, such as I-beams, H-beams, angle bars, wide flange beams, and more.
03/
Electronic Equipment
Steel has a high melting point, making sheet metals suitable for use in electronic goods. Some examples would be CPU housings, mobile phone cases, heat sinks, iron cores, circuit boards, and the like. As these components require electrical energy to function, they may end up producing high heat levels that can affect the other parts.
04/
Automotive Parts
Automotive parts manufactured from steel coils can be found almost anywhere in a vehicle — from the chassis framework, car doors, exhaust, dashboard system, wheels, rims, engine, suspension, and the like. The high strength-to-weight ratio, durability, heat resistance, and non-combustibility of steel coils make them ideal due to the heat produced in a vehicle's combustion engine. Like electronic consumer goods, vehicle parts will remain intact when steel coils are used.
Process
Steel coils are produced by taking a piece of steel and rolling it out into a long, thin strip. The strip is then wound up into a coil and transported to the steel mill for further processing.
The first step in making steel coils is to take a large piece of steel and roll it out into a long, thin strip. This can be done with a variety of different machines, but the end result is always the same: a long, thin strip of steel.
Once the strip has been created, it is then wound up into a coil. This helps to keep the steel organized and makes it easier to transport. The coil is then transported to the steel mill for further processing.
