In industries like construction, furniture, and pallet manufacturing, the durability of coil nails directly impacts the quality of construction and product lifespan. While many focus on nail diameter, nail spacing, and nail head, have you considered the coating thickness? It is the key factor in determining the rust resistance of coil nails!
How much difference does coating thickness make in rust resistance?
Electro Galvanized – Regular thickness: 3-5μm, suitable for indoor construction, but with limited rust resistance. Mechanical Galvanized – Thickness: 30-50μm, more corrosion-resistant than regular electroplating, can withstand 150-200 hours of salt spray testing, ideal for humid environments.
Hot-Dip Galvanized – Thickness: Over 50μm, suitable for outdoor and highly humid environments, such as bridges and wood structures, can withstand 300 hours of salt spray testing.
Stainless Steel (304/316 Stainless Steel) – No coating required, naturally rust-resistant. 316 stainless steel can withstand corrosion in marine environments but is more expensive.
Why is coating thickness so important?
Coating too thin → Nails may rust within a few months in humid environments, compromising structural safety.
Uneven coating → Some areas are more prone to rust, leading to decreased holding power, impacting construction quality.
Suitable coating thickness for the environment → Significantly extends the nail's service life and reduces maintenance costs!
