Product Description

  Hexagonal head self-drilling screws with coating are based on ordinary hexagonal head self-drilling screws, with an added special coating (such as zinc-aluminum coating, Dacromet coating, hot-dip galvanizing, or electro-galvanizing) to enhance corrosion resistance, weather resistance, and service life. Their applications are more extensive,especially suitable for outdoor, humid, and highly corrosive environments.

1. Steel Structure Engineering

• Suitable for securing steel structure workshops, bridges, and steel purlins.
• With excellent corrosion resistance, it is ideal for steel structure installations in coastal and high-humidity areas.

2. Roofing and Wall Panel Installation

• Used for installing metal roofing and wall panels, such as color steel tiles, sandwich panels, and corrugated sheets.
• When paired with EPDM rubber washers, it prevents water penetration and enhances waterproof performance.

3. Solar Photovoltaic (PV) Mounting Systems

• Solar panel brackets are typically installed outdoors, exposed to wind and rain for extended periods.
• Coated self-drilling screws effectively prevent rust and extend the service life of photovoltaic systems.

Advantages of Hexagonal Head Coated Self-Drilling Screws
Superior Corrosion Resistance - Designed for harsh environments, offering excellent salt spray resistance (up to 500-1000 hours or more).
Outstanding Weather Resistance - Withstands high temperatures, humidity, and acid rain, making it ideal for long-term outdoor applications.
High-Strength Self-Drilling Capability - Efficiently drills through metal, wood, and other materials without the need for pre-drilling.
Quick and Easy Installation - Reduces construction steps, enhances installation speed, and improves overall work efficiency.
