It happens to the best of us. After a long day of scrapping, you spot a beautiful piece at the other end of the yard. As you get closer, you notice that one half is obscured by an old barrel. By the time you move the barrel, the jig is up—the entire lower section of your piece is coated in rust.
So what should you do? Is the rusted metal recyclable? And even if it is, will the scrap metal recycler pay for a rusted piece?
In this case, you have a few options. But before you decide what to do next, it may help you to know a bit more about rust.
What Is Rust?
Rust is a form of corrosion that occurs when a ferrous metal, or a metal containing iron, is exposed to water. How long it takes for rust to form depends on the exposure level, the type of alloy and whether the metal was coated. So an old bike left in a humid basement may begin to rust after a few weeks, or it could stay rust-free even after a winter outdoors.
Because this type of corrosion is specific to iron and its alloys, rust does not impact copper salvage price or the scrap value of aluminum. These metals may show signs of corrosion, but they are different from rust. Rust is an issue specific to iron scrap, which already is one of the lower value scrap metals.
Can I Recycle Rusty Metal?
Yes. Ferrous scrap metals go through a purification process when they are recycled to clear off paint and coatings. This process will draw out the iron, but the amount may be smaller than in non-rusted scrap. Because of this, the price offered per pound of rusty scrap may be less than that of iron scrap with a cleaner appearance.
Metals That Rust the Most
In the world of industrial manufacturing and contracting, knowing which metals are prone to rust can keep your operations smooth and efficient. Here are the metals that rust the most, along with common items they’re used in:
- Iron. Found in large beams and structural frames in buildings. Highly prone to rust, especially in outdoor or humid environments.
- Carbon steel. Used widely in pipelines and construction materials. Although affordable and strong, it rusts quickly without a protective coating.
- Cast iron. Often used for engine blocks and heavy machinery components. Durable yet susceptible to rust, it requires regular maintenance.
- Wrought iron. Common in outdoor gates and architectural details. Needs a protective finish to prevent rusting.
- Mild steel. Utilized in automotive bodies and infrastructure supports. Prone to rust; a layer of paint or galvanization is usually required.
- Low alloy steel. Seen in bridges and pressure vessels. Resistant to stress but not rust, needing protective treatments.
- Tinplate. Available in HVAC systems and food containers. The steel can rust if the tin layer is scratched or damaged.
- Weathering steel. Used in outdoor sculptures and structures. Forms a rust layer that protects, but prolonged exposure can still cause damage.
- Tool Steel. Employed in manufacturing tools and molds. It resists wear but can rust without proper care.
- Ordinary steel. Seen in construction and auto parts, ordinary steel needs consistent maintenance to avoid rust.
To protect your metals from rusting during ongoing projects there are some effective preventive strategies you can do. Firstly, applying protective coatings is essential. These can include paints, primers, or galvanization to shield metals from moisture and oxygen. These coatings form a barrier, preventing rust from forming on the metal surface.
Controlling the environment where metals are stored is equally important. Aim to keep storage areas dry, using dehumidifiers if necessary, particularly in regions with high humidity. Simple measures like avoiding direct contact with wet surfaces or grounds by using pallets can make a significant difference.
Using efficient storage solutions can also help. Consider pick-up and drop-off services to limit the time metals spend in outdoor conditions. Roller bins are another practical option, providing easy mobility while keeping metals elevated from potentially moist surfaces.
By combining these methods, you extend the life of your materials and reduce maintenance costs. Gardner Metal Recycling is here to partner with you in maintaining the quality and durability of your industrial operations. Whether it’s providing roller bins, handling the logistics of pick-up and drop-off, or advising on the best protective measures, we’re ready to support your business needs.
Rusty Metals that Can Still be Recycled
When you think about rusty metals, you might assume they’re destined for the landfill. But the truth is, rusty metals can still hold value and be successfully recycled. Here’s how and why even the rustiest metals can be given a new life.
Rust doesn’t alter the core metal. Despite the appearance of rust, the underlying metal— be it iron, steel, or other alloys — remains intact. The rust itself is essentially an outer layer of oxidation that, while unsightly, doesn’t negate the recyclability of the material. This means that, beneath the rust, the valuable material remains ready for processing.
Here’s some items to be on the lookout for:
- Steel beams. Often used in construction, they can rust when exposed to the elements.
- Iron pipes. Common in industrial plumbing systems and prone to rust over time.
- Reinforcement bars (rebar). Used in concrete construction and susceptible to rust in damp conditions.
- Machinery frames. Structural elements in heavy equipment that can rust with wear and exposure.
- Sheet metal. Found in HVAC ductwork and equipment housing, which can rust in outdoor settings.
- Metal roofing panels. Used in industrial buildings and can rust without proper maintenance.
- Shipping containers. Used for transport and storage, susceptible to rust especially in coastal areas.
- Heavy equipment parts. Such as bulldozer blades and excavator arms, which can rust with heavy use.
- Railings and fencing. Frequently exposed to the elements, leading to rust over time.
- Industrial tanks. Used for storage of water or chemicals, these can rust from both the inside and outside.
- Aircraft components. Parts like wing struts and fuselage skins, often made from aluminum or steel, can corrode when exposed to moisture.
Why Recycle Rusty Metals?
Recycling rusty metals isn’t just about doing the right thing—it’s about boosting your bottom line. Even rusty metals hold value. Selling your scrap can turn potential trash into cash, offering your business a nice return.
When you recycle, you’re also supporting a circular economy. Instead of new raw materials, you’re using recycled ones, which can cut costs and make your supply chain more reliable. It’s a smart move to stay competitive in an ever-changing market.
In Austin, improper disposal of metal waste can lead to fines. Recycling helps you avoid these penalties, keeping your business compliant with local regulations and saving money in the process.
Plus, demonstrating a commitment to sustainability can enhance your reputation. Clients and customers appreciate businesses that care about the environment and act responsibly. This can strengthen relationships and build trust.
Finally, while you’re boosting profits and avoiding fines, you’re also contributing to a healthier planet for future generations. Recycling rusty metals is a win all around, and Gardner Metal Recycling is here to help make it easy and profitable for you.
How to Recycle Rusted Metal
When dealing with rusty metal, the first step is to assess what you have. It might seem like a pile of junk, but rusty metals still hold value beneath that layer of oxidation. Rust itself doesn’t damage the core metal. It’s merely an outer layer that can be stripped away. This means that even if items look unsightly, they can still be processed and reused in various ways. The key is to understand the potential of what you’re dealing with.
Begin by sorting through your materials. Identify the types of metals you have—iron, steel, and other alloys are most commonly found in industrial settings. Knowing what you have will help you gauge their worth when it comes to recycling. If you come across items like rusted beams, old machinery, or pipes, you may be surprised to find that these materials are still valuable in the recycling market. This initial assessment can change your perspective on how you view scrap material and can create potential returns for your business.
Once you’ve sorted and assessed your materials, it’s essential to consider the recycling process. The next step usually involves cleaning or preparing the metal as much as possible, although recyclers can handle most of the work. It’s beneficial to remove any non-metal components, such as plastics or wood, which can add to the bulk but won’t add to the value of the metal itself. While rusty metals can look rough, removing any lingering debris will improve processing at the recycling facility and can help maximize your return.
Safety First
It’s not just about the financial aspects. Safety is a critical concern when handling rusty metals. Working with rusted materials can lead to injuries if not done right. These metals often have sharp, jagged edges that can cause cuts or puncture wounds. Furthermore, rusted structures are not always stable; they might crumble under pressure or become unpredictable when lifted. To protect yourself and your team, always wear gloves and durable protective gear when moving these materials. A pair of heavy-duty gloves, long sleeves, and eye protection can go a long way in preventing injuries.
Additionally, it’s vital to assess the condition of these metals before reuse. Rust can weaken metal significantly, making it risky to incorporate those materials into any structural projects without a professional assessment. For instance, a rusted beam may look intact, but hidden weaknesses could compromise the overall integrity of a building. Instead of risking safety, consider recycling these weakened materials rather than trying to reuse them. By taking the safer route, you not only protect your team but also ensure that the materials you handle are processed responsibly.
Once you’ve prepared your rusted metals, it’s time to choose a reliable recycling facility. Look for companies that specialize in industrial scrap metal recycling, like Gardner Metal Recycling. When you arrive at the facility, our staff will evaluate the materials you’re bringing in. We’ll weigh the metal and determine its value based on current market rates. Be prepared for the fact that heavily rusted items might fetch slightly lower prices, but even then, selling rusty scrap is far better than tossing it into a landfill.
In conclusion, recycling rusty metal is not just a responsible choice — it’s a smart business decision. By assessing what you have, ensuring safety, and partnering with a reputable recycler, you can turn potential waste into profit. This not only helps your bottom line but also positions your business as a leader in sustainability. With the right approach, rusted metals can transition from scraps to valuable resources while keeping your workplace safe and compliant with local regulations.
How to Remove Rust
There are plenty of products on the market for removing rust. Visiting your local hardware store is a quick way to get recommendations for the best product for the type of rust you are trying to remove. If you are looking for a DIY option, some people swear by using soda pop or other home-blended mixtures for a cheaper rust solution. If you want to go that route, your best bet may be to get a few lemons, cut them in half, and dip them in salt—then use them as scrubbers to clean the rusted areas. Whatever your method, remember that rust is iron oxide, so it contains iron. As you clean off the rust, you are also cleaning away the metal itself.
For those wanting more DIY options, there are simple household ingredients that can help tackle rust effectively. One popular choice is vinegar. White vinegar contains acetic acid, which can dissolve rust. Simply soak your rusted items in vinegar for a few hours or apply it directly to the rusty areas. After letting it sit, scrub the rust away with steel wool or a wire brush. If the rust is particularly stubborn, you can repeat the process. This method is not only effective, but it’s also inexpensive—typically costing just a few dollars for a bottle of vinegar.
Another effective and cost-efficient rust remover is baking soda. By creating a paste with baking soda and water, you can apply it directly to rusted areas. Allow it to sit for at least 30 minutes, which gives the baking soda time to break down the rust. Afterward, scrub the area with a brush or scouring pad. Since baking soda is commonly found in most households, this solution is budget-friendly and often under $5 for a box.
If you want to get more creative, you can also try using hydrogen peroxide and baking soda together. Mix equal parts hydrogen peroxide and baking soda to form a thick paste. Apply this mixture to the rusted areas and allow it to sit for about an hour. The hydrogen peroxide will react with the rust, and the baking soda will act as an abrasive to help scrub it away. This method is effective and usually costs less than $10 in total for both ingredients.
As you explore local products designed specifically to remove rust, look for items that contain phosphoric acid or oxalic acid. These ingredients are known for their rust-dissolving properties. Many well-known brands offer rust removers that are easy to use—simply apply the product according to the instructions, let it sit for the recommended time, and then rinse off. Prices for these commercial rust removers typically range from $5 to $20, depending on the brand and quantity. When considering cost, it’s essential to weigh this against the value of the metal scrap. Spending more on a product than you might recover from the scrap can negate any benefits.
For instance, if you’re planning to recycle metal and the potential payout for that rusted piece is about $20, you wouldn’t want to spend more than that on rust removal. Always consider the amount you’ll be investing in rust removal versus how much you might earn back from recycling the cleaned metal.
After you’ve successfully removed the rust, make sure to rinse the items with water to take off any leftover cleaning solution. Dry them completely to prevent new rust from forming. Applying a protective layer, such as a metal primer, can also help shield the metal from future rust.
While removing rust might take a bit of time and effort, these DIY solutions make it cost-effective and easy. With household ingredients readily available and affordable local products at your disposal, you can restore your rusty metal and ensure it holds its value in the recycling process.
Getting the Best Iron Scrap Price
Most metal scrap recyclers will pay for items by weight. They may also consider things like condition when they are determining the rate that they will pay you per pound. While cleaning the rust off of iron scrap may improve the appearance (and therefore the price per pound), it also reduces the weight.
So, when you are deciding whether to haul and clean that rusty piece of metal, consider if your efforts match what you expect to get back in increased value at the scrap recycling yard.
The guaranteed way to get the best price on ferrous scrap metals is to prevent rust formation in the first place. Keeping metal in a low humidity environment and using protective paints or coatings will help ensure that your metal stays clear of rust.
