Steel is a leading choice in constructing modern buildings, multiplexes, high rises, and many other structures. It’s favored by many thanks to its robust nature and durability.
However, steel at some point starts developing rust. And this is particularly true if preventive measures aren’t applied. For this reason, corrosion resistance has become a hot topic, and different types of rust inhibitors get injected into the market daily.
Steel corrosion- what is it all about?
Steel is one of the robust metals ever known in history. Surprisingly, it’s strength and reliable characteristics can’t save it from rust. Corrosion of steel is the reaction between the metal and the environment. This results in the deterioration of the metal, which compromises its quality over time.
How does it happen? Corrosion forms oxide, which is higher in volume compared to the original steel. Corrosion also results in peeling and causes voids on the surface of the metal. This then lowers the resistance of the steel, making it weaker and more vulnerable to rust.
How can you avoid corrosion?
With the many effects of corrosion, most governments are now stricter on the quality of steel. More and more companies are now embracing modern technology to manufacture top-quality steel to enhance its strength and resilience.
The best way to deal with corrosion in construction is through using Glass Fiber Reinforced Polymer. This is also referred to as fiberglass rebar and is an excellent alternative to steel. Fiberglass bar is corrosion-free, lightweight, and long-lasting. It’s also stronger than steel!
Corrosion inhibitors are also useful. They coat the metal base and provide a protective layer to hinder further corrosive reactions. There are various corrosion inhibitors available in the market. These are;
- Anodic inhibitors
These inhibitors form a protective oxide film on the metal’s surface. Examples are chromates, nitrates, tungstate, and molybdates, and all reduce corrosion on the said metal.
- Cathodic Inhibitor
Cathodic inhibitors decelerate the cathodic reaction to lessen the diffusion of reducing species on the metal’s surface. Examples are oxygen scavengers and cathodic poison.
- Mixed inhibitors
Mixed inhibitors form a film on the metal’s surface to reduce the cathodic and anodic reactions. Examples of commonly used mixed inhibitors are phoptes and silicates. They are commonly used as water softeners to curb the formation of rust water.
- Volatile corrosion inhibitors
These are transported through volatilization to the site of corrosion. This happens in a closed environment like in boilers, a compound such as morpholine is transported with steam to hinder corrosion in condensation tubing.
What should you consider when shopping for corrosion inhibitors?
How safe is the product? Is it environmentally friendly? Consider the safety of the products, and pick one that doesn’t harm human life in any way. The best rust inhibitor shouldn’t contain toxic elements that can sip into water bodies and harm humans and aquatic life.
A perfect example is Inhibispheres; they are a safer replacement to harmful chemicals and organic elements. They are environmentally friendly and excellent alternatives for corrosion elimination.
The coating should be compatible with the corroded steel to avoid further reactions. It should also be resistant to adverse weather conditions and should be non –reactive. With such features, you can be assured that no further deterioration and reactions will take place.
3. Frequency of application
For some rust inhibitors, you have to re-apply after a certain period to avoid a further reaction. This is usually one or two years. However, there are now more advanced coatings that you can apply once, and forget about corrosion on your metal. Such corrosion inhibitors are highly effective in rust prevention and elimination. They are a cost-effective way to dealing with corrosion.
The durability of the protective coating determines how long it can shield your metal from further corrosion. If it’s not durable enough, you’ll have to keep buying more to prevent further corrosion. A durable product will last long and is likely to offer the best protection to your steel.
5. Mode of application
Consider the mode of application and if you can do this with ease. For some products, you apply with a brush. For others, you use a gun to smear powder to your steel. If you’ll need to hire an expert to apply the coating, this then translates to additional costs, and you should budget for that. The best rust inhibitor is easy to apply and requires minimal skills.
6. Product cost
There are different types of rust coatings in the market. All have distinctive features and come at varying costs. You want to acquire high-quality products and at the best prices. Set a budget and acquire quality products that match your budget.
Moreover, search for exciting deals from different stores, and locate the best offers. The rule of thumb, don’t compromise on quality. You’d rather stretch your budget and get superior quality products.
How can you get cost-effective corrosive prevention coatings?
There are different types of corrosive prevention coatings in the market. To get the best deals, decide on where to shop. This can be a physical store near you or an online outlet. While you can get products at reasonable prices in land-based stores, you can still locate amazing offers online. Head to Google and search for shops offering discounts on your desired products.
Compare the offers and prices among different sites before making purchases. Also, consider the cost of delivery or shipping, and compare the rates between the different shops. What’s the essence of purchasing cheaper products and end up paying more due to delivery charges?
Moreover, take advantage of the sites offering the most exciting deals, and shop during the off-season. Most people rush to buy anti-corrosive coatings and paints during cold and rainy seasons when corrosion is likely to happen.
Acquire your product when fewer people are seeking such products and enjoy lower prices. If possible, shop in bulk and from one shop. You’re likely to get discounts when shopping for all your products at a go.
A quick wrap up
The list of factors to consider when shopping for corrosion inhibitors is endless. All in all, acquire quality products and shop from legitimate vendors. Also, search online for corrosion prevention tips to help maintain your steel products in excellent condition.
