Maximize durability with our tough Sherardised Nails. Unlike standard galvanising, the zinc coating is thermally diffused into the steel, creating a hard finish that won't chip or flake under hammer blows. Ideal for external cladding, fencing, and glazing beads, these nails offer exceptional corrosion resistance in harsh environments. Their textured matt grey surface also provides an excellent base for painting. Shop for long-lasting exterior protection.
