Metals Processing: Advantages of Cold Rolled Steel

2022-08-05T16:30:32+00:00March 14th, 2022|News Blog|

There are many steps required in metal processing in order to achieve a high-quality product. American steel processor, National Material Company (NMC), believes there can be no exception to this rule. Steel is an alloy that is a mixture of both iron and carbon and it is durable, sustainable, and highly desired by many industries. Formal specifications and different grades of steel can affect the performance and use of the metal, but there are additional techniques within the metals’ processing that can alter the strength and finish. In this article, we will focus on one technique known as cold rolling.

Engineers and designers alike must decide on the type of metal they will need to begin work on their projects. Cold rolled steel for many reasons might be the ideal metal. “Cold rolled” refers to the process the steel undergoes before becoming the final product. The temperature is not what we may consider “cold.” Instead, the entire process occurs at room temperature and involves applying great pressure to the steel. However, this does not mean cold rolled steel never experiences its recrystallization temperature. In fact, cold rolled steel endures extreme temperatures and compression rollers just like hot rolled steel. Cold rolled steel simply undergoes more processes once it has cooled down to get exact dimensions and better surface qualities. In many cases, steel may undergo processes like rolling, turning, grinding, and polishing. Each one gives the steel a unique finish.

There are many advantages of cold rolled steel, such as increased strength. (Read about Advanced High Strength Steel, or “AHSS” here.) The compression of the steel at room temperature hardens the strain, giving the metal significant strength when compared to other types of steel. That being said, the steel is not needlessly thick to create this strength. Cold rolling allows for tighter tolerances not found within other steel manufacturing. In other words, the metal will have thinner walls without sacrificing integrity.

One of cold rolled steel’s most desirable aspects is its aesthetics. The cold rolling process enables metal processors like National Material Company to improve the surface finish. It leaves a smooth surface with few imperfections that are ideal if a project requires visual appeal. An excellent surface is great not just for its beauty, however. Cold rolled steel is used in the construction of bridges due to fewer visible surface flaws.

Additionally, cold rolled steel is ideal for projects that require more precision and need to be durable. Bars created with this technique have well-refined edges, and tubes are very straight with excellent concentric uniformity.

Cold rolled steel can be found across many industries today. It is used in parts for home appliances, roof and wall systems, metal furniture, aerospace structural members, and a wide scope of applications too numerous to list. Despite the many steps within the cold rolling process, cold rolled steel has a short manufacturing time and can be delivered promptly so customers can begin work on their projects quickly.

What is Precision Slitting?

In the metal processing world, every new contract comes as a new and customized challenge. Increased demand for steel coils with finer width and length parameters have ushered in an era of more robust precision slitting – with technological advancements in slitting equipment, software, and tooling practices fueling the wave.

Slitting is a metal manufacturing process wherein a coil of material, such as aluminum or steel, is slit into the lengths and widths specified by the end application. As the material runs through the machine, the steel rolls are moved through extremely sharp circular blades, making the cuts. In order to make the slice, substantial compressive forces must be applied – and when the forces exceed the tensile strength of the material, it slices. The end product is long strips of material cut to the buyer’s specifications.

A steel slitting machine is comprised of three major parts – the uncoiler, the slitter, and the recoiler. In order to ensure that the quality of the process is optimized, each element must be precisely aligned during setup.

National Material’s breadth of slitting capabilities is of tremendous value to our customers, who know that we have the right equipment to  process their orders on time and to the right specifications. Our customers appreciate the high level of precision and quality we offer in our slitting process, as it eliminates the excess material waste that can be produced by their own manufacturing processes creating real value.

What is a Toll Processing Company?

The convenience of outsourcing manufacturing work for products and services is becoming more and more popular. This method of contracting with a material processing service center is known as toll processing. (Also known as tolling, contract processing, toll manufacturing, or toll conversion.)

Businesses turn to toll processing because of the expertise and cost savings that the processing center provides. A growing business might lack the facilities, manpower, and time required to process the materials required for their products, leading to shortfalls in efficiency and delivery. Usually, processing centers have decades of experience in a number of different industries,  They have also made significant investments in equipment that can help take a project from concept to completion. Toll processors can offer the contracting company with important information, including difficulties or circumstances that might be encountered when processing specific types of material.

Benefits of toll processing

  • Significantly reduced capital investment
  • No additional permits required
  • No need for additional storage space
  • No need to hire additional employees
  • Can adjust production levels on-the-fly depending on demand
  • Faster time to completion
  • Opportunity to expand your network by working with experienced professionals
  • Avoid extended lead times
  • Affordable costs

Types of toll processing services

Toll processing companies, such as National Material Processing, can cover a wide range of services for their clients. This includes services such as slitting, configured blanking & stamping, cut-to-length processing, pickle & oil, galvanizing / galvannealing, product storage, shipping, , quality analysis, and more.

How to find the right toll processing company for you

When looking for a company to contract with, you should consider a few key factors. First, you should try to select a company that is reasonably located nearby in order to create supply chain savings. The quality of the team of professionals you’re going to work with, as they are going to become an extension of your business once you enter into a contract with them.

Your chosen toll processor will become the link between you, your customers, and your product, and this choice should not be taken lightly. You should choose a company that will not only make your manufacturing processes easier, but also a company that can reduce risk, add to your bottom line, and put you ahead of the competition. Review their quality assurance and control procedures, their supply chain management experience, and their track record.
