Graphene, long-lasting protection, low cost, high performance

What you're seeing is not a sci-fi disaster movie, but the real fate of steel piles without protection! Deep in the vast ocean, steel piles without protection are suffering from the relentless corrosion of seawater, enduring the pain of corrosion every second and slowly heading toward decay.

But in the hands of engineers, a series of targeted protective solutions are quietly rewriting the fate of steel in the ocean!

In the mud zone, often covered by seabed mud, we apply two layers of graphene glass flake primer, with a total thickness of 800 microns. The perfect combination of graphene and glass flakes forms a dense protective layer for the steel piles, effectively blocking the penetration of corrosive substances in the mud, greatly slowing the corrosion process of the steel piles.

In the splash zone, where the steel piles are sometimes submerged in seawater and sometimes exposed to the air, we use two layers of graphene glass flake primer combined with fluorocarbon topcoat, with a total thickness of 1080 microns. The primer provides an excellent foundation for adhesion and shielding performance, while the fluorocarbon topcoat resists seawater erosion and ultraviolet rays, offering all-round protection for the steel piles.

For the atmospheric zone, where the steel piles are exposed to air for long periods, a protective system of 280 microns is created by graphene zinc powder primer, epoxy zinc-rich intermediate coat, and fluorocarbon topcoat. The graphene zinc powder primer provides cathodic protection to prevent rusting; the epoxy zinc-rich intermediate coat enhances adhesion between layers while also offering shielding; the fluorocarbon topcoat further improves the coating's weather resistance, ensuring the steel piles remain in good condition despite wind, sun, and rain.

These carefully designed coatings tightly adhere to the steel pile surface, fortifying the safety defense of the piles.
