Prestressed steel strands are core load-bearing components in bridges, high-rises, and large-span structures, and their corrosion resistance directly determines the service life and safety of the entire project. As a professional source manufacturer, we offer a full range of high-performance corrosion-resistant coating solutions for PC steel strands, tailored to different working environments:
1. Galvanized Coating
Adopt hot-dip galvanizing or electro-galvanizing process, forming a dense zinc layer on the PC steel strand surface. It has excellent barrier protection and sacrificial anode anti-corrosion effect, suitable for general atmospheric, soil, and mild corrosive environments. Our PC galvanized steel strands comply with GB/T 5224 and ASTM A416 standards, with zinc layer thickness controllable according to customer requirements, ensuring uniform coating and no peeling.
2. Epoxy Resin Coating
The PC steel strand surface is coated with high-quality epoxy resin through electrostatic spraying and high-temperature curing, featuring strong chemical resistance, acid and alkali resistance, and salt spray resistance. It is ideal for harsh corrosive scenarios such as coastal areas, industrial zones with acid rain, and sewage treatment structures. The coating has high adhesion, smooth surface, and will not affect the tensioning and anchoring performance of PC steel strands.
3. Zinc-Aluminum Alloy Coating
A new generation of high-efficiency anti-corrosion coating, composed of zinc-aluminum alloy with special additives. It integrates the advantages of galvanizing and aluminum plating, with corrosion resistance 3-5 times that of traditional hot-dip galvanizing. It is suitable for long-term outdoor projects in extreme environments such as marine climate, high humidity, and high salinity, effectively extending the service life of PC steel strands to over 50 years.
4. Duplex Coating System (Galvanizing + Epoxy Resin)
For ultra-harsh corrosive conditions, we provide a composite coating solution: first apply a galvanized layer for sacrificial protection, then cover with an epoxy resin layer for double barrier defense. This system maximizes anti-corrosion performance, perfectly matching the service life requirements of key projects such as cross-sea bridges and nuclear power plants.
Our corrosion-resistant coated PC steel strands are all tested by third-party authorities for salt spray resistance, adhesion, and mechanical properties before leaving the factory. Combined with our matching anti-corrosion anchorages and professional construction guidance, we can provide one-stop anti-corrosion solution for your prestressed projects.
