Product Q&A

Q:Why choose a twisted shank over a smooth shank for roofing nails?

The twisted (spiral) shank offers significantly higher holding power. As it is driven into the wood, it rotates like a screw, creating a mechanical lock that prevents the nail from backing out due to wood shrinkage or wind vibration.

Q:What is the benefit of the umbrella head design?

The umbrella head is oversized to cover the hole created during installation. This acts as a primary seal against water, preventing leaks and protecting the roofing material from tearing at the pressure points.

Q:Is the galvanization durable enough for coastal areas?

For standard use, our Electro-Galvanized nails offer great value. However, for coastal or highly humid C4/C5 environments, we recommend our Hot-Dip Galvanized (HDG) version, which provides a much thicker zinc layer for long-term corrosion resistance.

Q:Can these nails be used with aluminum roofing sheets?

Yes, but we recommend using them with a compatible rubber washer if direct galvanic contact is a concern. Our nails are primarily engineered for carbon steel and zinc-coated roofing systems.

Q:What sizes are most common for export?

The most popular export sizes are 2.5' (65mm) and 3' (75mm) in 9BWG or 10BWG thickness. We can customize the length and diameter based on your local market standards.
