Steel nails & Self-Tapping Screws

1. Steel Nails

Steel nails are common fasteners made of high-strength carbon steel, used for fixing wooden battens, roof shingles, and auxiliary structures on the roof.

Role in Solar Tile Installation

　　•Fix Preservative Wood Battens, counter battens, and roof sheathing firmly to the roof structure.

　　•Secure lightweight accessories and auxiliary supports for the solar tile system.

　　•Provide temporary or permanent fixing during roof construction.

Key Performance

　　•High hardness and strong penetrating force.

　　•Good shear resistance to resist wind load and tile displacement.

　　•Anti-corrosion surface treatment (galvanized) for outdoor weather resistance.

2. Self-Tapping Screws

Self-tapping screws are threaded fasteners that can form their own mating threads when driven into metal, plastic, or wood, without pre-tapped holes.

Role in Solar Tile Installation

　　•Secure solar tile mounting brackets, metal rails, and hooks to steel or aluminum structures.

　　•Fix flashing sheets, waterproof membranes, and metal accessories tightly.

　　•Ensure stable, long-term connection of the solar tile system under vibration and thermal expansion.

Key Performance

　　•High tensile and pull-out resistance.

　　•Self-drilling / self-tapping design for quick and easy installation.

　　•Galvanized or stainless steel finish for excellent anti-rust and anti-corrosion performance.

　　•Stable under outdoor weather, UV, and temperature changes.
