8 Industrial Uses Of Secondary Steel


One of the most important and common materials used in construction is steel. Many buildings—be they residential, commercial, or industrial—heavily rely on steel. Currently, the use of secondary steel is heightening. It’s manufactured from the remains of primary steel to be recycled and molded. This kind of steel has no mill certifications, and it’s cheaper compared to primary steel.

Secondary steel can also be the result of processes such as steel slitting. It serves to fulfil specific customers’ needs. There are several benefits associated with secondary steel. Here are just some of them:

  • Durability: Structures built with secondary steel can withstand wear and tear for a long time. They also come with less maintenance costs compared to wooden structures.
  • Affordability: Since secondary steel is manufactured from scrap iron, the end result is usually inexpensive. But this doesn’t imply that its performance is substandard. Just like primary steel, it can be used in a wide range of projects. If you’re looking for reasonably priced construction materials without compromising quality, you can look into reputable businesses that buy and sell steel in order to solve your problem.
  • Lightweight: Secondary steel girders and beams are lighter than their wooden counterparts. This implies that handling them won’t be that strenuous.
  • Sustainability: Since steel in general is recyclable, utilizing secondary steel in construction eliminates wastage and damage to the natural surroundings.

How Is Secondary Steel Used?

Given how advantageous secondary steel is, it’s not surprising that it has many industrial applications, including the following:

1. Surface Casing

Surface casing is a pipe installed in gas and oil wells. It’s placed near a well to safeguard water sands against leakage or contamination resulting from gas or oil drilling projects. Surface casings are used in concrete pilings in many construction processes, too.

2. Frame Construction

Secondary steel can be utilized in forming the frame that supports primary frames in the construction of houses. That kind of support is crucial to ensure that the main frames don’t twist or break. Frames made from secondary steel also help in attaching walls and roofs. These are several common framing parts you may encounter:

  • Struts: These are brace stabilizers that carry loads along their axis.
  • Studs: These are posts positioned vertically for the attachment of interior drywall.
  • Track: These are curved structures where studs are anchored in the construction process.
  • Girts: These are stabilizer bars positioned horizontally between external columns.
  • Purlins: These are stabilizers horizontally placed between rafters where the roof assembly is usually attached.
  • Wall Bracing: This refers to strips, cable rods, and bars that prevent shearing, thus yielding additional lateral stability.
  • Eave Struts: These are transition pieces placed between roof purlins and wall girts along eaves in construction.
  • Joists: These are beams that support the floor.
  • Jambs And Headers: These are frameworks for openings like windows, bays, and doors.

3. Pipe Making

Recycled steel can also be used to manufacture pipes, which could be irrigation, plumbing, or water pipes. These end products of recycled steel work as well as their counterparts made from primary steel.

4. Packaging Uses

Secondary steel can be used in manufacturing food packaging materials and beverage containers. The process involved is usually cost-effective and doesn’t harm the environment.

5. Automobiles

Secondary steel is considered a strong and affordable material in the production of some vehicle parts. Even old automobiles are recycled to make new ones. This is possible because steel doesn’t degrade quickly.

6. Home Furniture And Appliances

Couches, tables, and chairs can have legs made from secondary steel. When it comes to designing modern furniture, steel can be incorporated in order to come up with stylish designs. What’s more, offices can have modern cabinets and sleek desks manufactured from secondary steel. Lightning fixtures, refrigerators, stoves, and dishwashers have parts constructed from recycled steel as well. These home appliances and furniture are all durable.

7. Signs And Creative Endeavors

Secondary steel can be used for outdoor road and entryway signs. Meanwhile, some communities turn to secondary steel to produce outstanding sculptures. These artistic pieces can last a long time.

8. Creation Of New, Sturdy Metal Products

With the aid of an electric arc furnace, secondary steel can be refined and turned into quality products. During the process, less energy is used, which ultimately helps in lowering costs. The metals manufactured can be used in railway and bridge construction.


The use of secondary steel in various industries is increasing. This is because of the benefits that come with this metal, among them being durability and affordability. In the long run, it may help contribute to the reduction of steel materials in landfills. Moreover, utilizing secondary steel is a great way to save on costs associated with primary steel.
