Cold-rolled low carbon steel coils are products that are further processed from hot-rolled steel coils by cooling annealing or temper rolling at room temperature. During cold rolling, the cooled hot rolled coil passes through another set of rolls at room temperature. Since the material is no longer hot and ductile, significantly higher pressures are required to compress it into the desired shape. Compared to hot rolling, cold rolling produces coils with tighter dimensional tolerances and a wider range of surface finishes.

Cold rolled steel has several advantages over hot rolled steel, such as:
Higher Strength: Cold rolled steel is 20% stronger than hot rolled steel, making it more suitable for high stress applications.
Better surface finish: Parts and products made from cold-rolled steel often have a smooth, shiny surface that is free of rust and scale.
Greater precision: Unlike hot rolled steel, cold rolled steel does not shrink after forming. This quality allows the creation of highly precise components with little to no secondary machining.
Cold Rolled Mild Steel Coils Applications Field:
Cold rolled mild steel coil is often used for applications that require tighter tolerances and better surface finish. Typical parts and products include: aerospace structures, home appliances, metal furniture, carbon strip/sheet/bar, machine parts, etc.

What are the different finishes of stainless steel?

From mill finishes to applied finishes, the stainless steel finishes that are applied to the surface of your stainless steel can play a bigger role than you may realize. While some products may only require standard stainless steel finishes, others may need something extra in order to enhance surface appearances, improve environmental performance or even reduce safety concerns.

But when it comes to stainless steel finishes. which level means that your metal is truly finished? That answer is ultimately up to you and the specifications you define for your project. Here is a closer look at the various stages of stainless steel finish for your material.

What Are Stainless Steel Coils?Stainless steel coil can be divided into cold rolled stainless steel coil and hot rolled stainless steel coil according to different production processes.
According to the materials, they can be divided into austenite, martensite, ferrite and duplex.
Common use stainless steel coils grades are often represented by digital symbols.
There are 200 series, 300 series, 400 series and duplex series.
304, 304L, 316 and 316L stainless steel coils are the most popular and economical grades of stainless steels.
Stainless steel 304/304L coils and stainless steel 316/316L coils, along with duplex stainless steel coils offer good corrosion resistance to many chemical environments as well as marine and industrial exposures.

What Are The Advantages of Using Stainless Steel Coils?
Stainless steel coils are an excellent choice for a variety of applications, including heating and cooling systems, food processing facilities and even your home.
They are highly durable and can withstand high temperatures. In addition, they offer many advantages over other types of metal coils:
Prolonged Lifespan
Stainless steel coils have a much longer lifespan than copper or aluminum. This means that you will get more use out of these coils before they need to be replaced. They also require less maintenance so you won’t have to worry about repairing them as often as other types of coils.
High-Temperature Resistance
Stainless steel coils can withstand temperatures up to 2,000 degrees Fahrenheit without melting or warping. This makes them ideal for industrial processes that involve extreme heat such as chemical manufacturing and oil refineries. They can also be used in residential applications such as cooking stoves and fireplaces where there is a risk of fire starting due to exposed flames from burning wood or coal fires.
Heat Transfer Efficiency
Stainless steel has excellent thermal conductivity properties that allow it to transfer heat quickly throughout its entire leng

​Our stainless steel sheet/plate is available in 300, 400 and 200 series. Each type has its own characteristics. The most popular grades are, 304 which can be easily roll-formed or shaped and due to its excellent corrosion resistance and weldability, it is one of the most popular grades available. 316 is an alloy that contains molybdenum which increases the corrosion resistance and is particularly effective in acidic environments as it provides a greater resistance to pitting corrosion. 321 is a variation of 304 with the addition of titanium, it is resistant to intergranular corrosion and has excellent weldability. Type 430 is a ferritic stainless steel alloy which offers good corrosion resistance and is predominately used in the domestic and catering industries.
