New Surface Treatment Boosts Durability and Appearance for Various Ground Piles and Connectors
In modern foundation construction, ground piles—including ground screws, driven piles, U-type anchors, flange bases, and other customised ground fixing solutions—are becoming increasingly popular due to their quick installation, re-usability, and minimal environmental impact. Compared to traditional concrete foundations, ground piles can be installed directly into the soil without excavation, greatly improving efficiency. They are widely used for solar mounting systems, fences, timber decks, tents, garden structures, and various landscaping projects.
In practice, different environments place high demands on the corrosion resistance of ground piles and their adjustable connectors. Hot-dip galvanising remains a common choice, but for certain adjustable components—such as nuts, brackets, and connecting parts—hot-dip galvanising can reduce the smoothness of threads or adjustable sections, making installation or future adjustments more difficult.
To address this issue, penetration galvanising has become an excellent alternative. Unlike standard hot-dip galvanising, this advanced surface treatment provides strong corrosion resistance—salt spray tests can reach 400 hours or more—while ensuring smooth, precise adjustability. In addition, this coating gives the surface a brighter and cleaner finish, offering a more refined appearance with better cost efficiency compared to traditional methods. This makes it ideal for parts that need to be adjusted or disassembled multiple times during use.
In a recent European project, all adjustable connectors for a batch of custom ground piles were treated with penetration galvanising. The salt spray test exceeded 400 hours, and on-site feedback confirmed that the adjustable nuts and fittings operated smoothly without any jamming or thread damage. The client praised not only the corrosion resistance but also the improved surface appearance and the cost-effective performance.
