Why are corrosion protection coatings important for infrastructure? Well, to answer this question, we first need to understand the threat of corrosion, what corrosion protection coatings are, and how, once applied, they improve the quality of infrastructures…
Fortunately for you, this blog will do exactly that!
Across many sectors, corrosion is one of the most persistent and costly threats. It can require constant maintenance to keep it in check and seriously impact the longevity of the infrastructure.
Whether it's the surrounding atmosphere, proximity to salt water, or frequent exposure to high temperatures and humidity, corrosion can lead to operational stresses and material degradation if left unmanaged. Hence, when it comes to the integrity of infrastructures, corrosion protection coatings are essential.
Once applied to a surface material, corrosion protection coatings increase overall structural resilience. Here at Alphatek, these types of coatings, along with thermal and fluoropolymer spraying, are our speciality. Our solutions are designed to extend component life and enhance their surface properties – so they can do what you need them to do, for longer.
Without further ado, here's why investing in corrosion protection coatings is important for infrastructure.
Economic Impact Of Corrosion
Did you know that, according to the Nace International Institute, corrosion costs the global economy $2.5 trillion each year? And it is projected that climate change will increase the deterioration of infrastructure.
When it comes to infrastructure, organisations must manage corrosion closely to prevent structural or functional failure. Unmanaged corrosion can lead to
- Safety hazards
- Service interruptions
- Maintenance expenses
- Asset depreciation
When it comes to the cost of corrosion, we're not just talking about the weakening of materials – corrosion undermines reliability, safety, and performance. Solutions to combat this, such as protective coatings, are an indispensable part of infrastructure management.
What Are Corrosion Protection Coatings?
Corrosion protection coatings are a composite of molten materials that, when sprayed onto a surface, isolate the underlying material from corrosive materials. This protective barrier then acts as a seal, preventing corrosion from damaging the quality or integrity of sprayed parts.
There are different types of corrosion protection coatings that react differently to corrosive elements to offer this level of protection:
- Barrier Coatings: Form a physical barrier that blocks contact with corrosive elements.
- Inhibitive Coatings: These coatings act as inhibitors, preventing the process of corrosion from happening altogether.
- Sacrificial Coatings: The surface of this coating will corrode in place of the substrate.
Infrastructure Applications
When we discuss thermal spraying in the infrastructure sector, there are various applications wherein additional corrosion protection is needed. Some of the wide uses of corrosion protection coatings in infrastructure are:
1. Transportation
Steel bridges, railway systems, and highway supports are constantly exposed to weather, pollution, and de-icing salts. Coatings protect structural steel from rust and reduce maintenance needs.
2. Water And Wastewater
Pipes, valves, and tanks used in water treatment and distribution face constant moisture exposure. Coatings provide essential waterproofing and chemical resistance.
3. Energy And Power
Power stations, offshore platforms, and transmission towers operate in some of the harshest environments. Advanced coatings help protect against both corrosion and thermal degradation.
4. Marine And Coastal Infrastructure
Seawalls, docks, and piers are under constant assault from saltwater and marine organisms. Fluoropolymer and metal spray coatings offer long-lasting protection.
5. Urban Structures
Street lighting poles, signage frames, and urban furniture benefit from aesthetically pleasing and durable coatings that withstand weathering and pollution.
Future-Proofing Infrastructure
With global infrastructure expected to expand rapidly over the next few decades, the need for durable, sustainable solutions has never been greater. By investing in corrosion protection coatings, asset owners and operators can:
- Prolong the life of critical infrastructure
- Reduce maintenance costs and disruptions
- Enhance safety and reliability
- Improve long-term return on investment
Importance Of Corrosion Protection Coatings For Infrastructure
