Hot Dipped Galvanized Roofing Coil Nails - 15° Collation, Corrosion-Resistant Fasteners for Asphalt, Metal & Wooden Roof Tiles

Product Overview

Hot Dipped Galvanized Roofing Coil Nails are premium-grade fasteners specially engineered for roof material installation, with full compatibility for asphalt tiles, metal tiles, and wooden tiles in both residential and commercial buildings. The hot dip galvanizing process immerses the nails in molten zinc, forming a thick, uniform protective layer that delivers exceptional antioxidant and corrosion-resistant performance—enabling long-term use in harsh weather conditions without rust or structural degradation.

Featuring sharp tips that penetrate roofing materials effortlessly and a 15° collation angle compatible with most mainstream coil nailers, these nails ensure secure, efficient installation that maintains roof stability and durability. Available in six lengths from 3/4” to 1-3/4”, with a fixed shank diameter of 0.120” (3.05mm), the product is packaged as 120 nails per coil and 60 coils per carton (7,200 nails total), meeting the high-volume demand of roofing projects.

Core Selling Points

• Heavy-Duty Hot Dip Galvanization: The thick zinc coating provides far superior corrosion resistance compared to electro galvanized nails, ideal for outdoor roofing applications exposed to rain, snow, UV rays, and coastal salt spray.
• Sharp Tip Design: Easily penetrates asphalt, metal, and wooden roof tiles without cracking or damaging the material, ensuring a tight and reliable connection.
• 15° Collation Compatibility: Matches standard 15° coil nailers, minimizing jams during high-volume installation and improving on-site work efficiency.
• 6 Length Options: Covers diverse roofing material thicknesses, from thin underlayment to thick wooden roof planks, with precise length matching for different construction needs.
• High-Volume Packaging: 7,200 nails per carton, suitable for large-scale residential and commercial roofing projects, reducing the frequency of coil replacement.

Installation Steps & Operational Recommendations

Standard Installation Process

1. Tool Preparation: Select a 15° coil roofing nailer; check the nailer’s magazine for cleanliness and ensure compatibility with the coil size.
2. Air Pressure Adjustment: Set the air pressure to 70-100 PSI—adjust according to roof material thickness: 70-80 PSI for asphalt/metal tiles, 90-100 PSI for thick wooden planks.
3. Coil Loading: Open the nailer magazine, insert the coil with the collation angle aligned to the guide, and lock the magazine to prevent coil displacement during operation.
4. Depth Calibration: Test fire a nail into a scrap piece of the target roof material. Adjust the depth control knob to ensure the nail head is flush with the material surface—avoid over-driving (which damages tiles) or under-driving (which reduces holding power).
5. Formal Construction: Position the nailer perpendicular to the roof surface, press the contact tip firmly, and pull the trigger to drive the nail. Maintain a 6-8 inch nail spacing for asphalt/metal tiles and 8-10 inch spacing for wooden roof planks.

Key Precautions

• Choose the appropriate nail length according to roof material thickness—ensure the nail penetrates the roof deck by at least 3/4 inch to guarantee structural stability.
• Do not use for non-roofing applications (e.g., heavy structural framing)—this product is optimized for roofing material fixation.
• Store unused coils in a dry, ventilated warehouse to avoid moisture accumulation on the zinc coating (though hot dip galvanization has strong corrosion resistance, damp storage may cause white rust on the surface).
• Wear safety goggles, non-slip work shoes, and gloves during roof installation to prevent falls and injury from flying debris.

FAQ (Frequently Asked Questions)

Q1: What is the difference between hot dipped galvanized and electro galvanized roofing nails?

A1: Hot dipped galvanized nails have a thick zinc coating (≥85μm) formed by immersion in molten zinc, providing long-term corrosion resistance for outdoor roofing. Electro galvanized nails have a thin coating (5-15μm) applied via electroplating, suitable only for indoor or dry outdoor applications.

Q2: Can these nails be used in coastal areas with high salt spray?

A2: Yes. The thick hot dip galvanized coating has excellent salt spray resistance, making it ideal for coastal roofing projects. For extremely harsh coastal environments, we recommend consulting our sales team for customized heavy-duty corrosion protection solutions.

Q3: What is the service life of these hot dipped galvanized roofing nails?

A3: In normal outdoor weather conditions, the service life can reach 15-20 years; in coastal or industrial polluted areas, the service life is about 10-15 years, far longer than electro galvanized nails.
