1. Corrugated Roofing Screws

Designed specifically for the most common roofing profile, these screws are engineered to attach corrugated roofing panels securely to both wooden and metal substrates. They feature optimized thread designs that prevent panel movement while ensuring a tight grip that withstands wind uplift.

2. Roofing Screws with Washers (EPDM)

Waterproofing is critical. Our screws come equipped with high-quality, integrated EPDM washers. When tightened, the washer compresses to form a durable, watertight seal around the puncture point. This design is essential for metal roofing applications, preventing leaks and protecting the structure from moisture damage over time.

3. Self-Tapping Roofing Screws (Sharp Point)

Speed matters on the job site. Our self-tapping roofing screws feature a needle-sharp point designed for rapid penetration. They are ideal for fastening roofing panels to wooden structures (like trusses and battens). The sharp point pierces the metal and wood effortlessly, ensuring a quick, easy, and stable installation without the need for pre-drilling.

4. Roofing Screws with Painted Heads

Aesthetics are just as important as performance. We provide roofing screws with painted heads to perfectly match the color of your roofing materials. Using durable, UV-resistant powder coatings, we ensure the screw heads blend in for a seamless, professional finish while adding an extra layer of protection against the elements.

5. Roofing Screws with Stainless Steel Caps

For harsh environments where corrosion is a major threat, we offer screws utilizing stainless steel caps. These capped heads provide superior durability and rust resistance compared to standard carbon steel, making them the ideal choice for coastal areas or industrial zones where longevity is paramount.

As a versatile roofing screw manufacturer, our products are the backbone of various construction sectors:

  • Metal Roofing (Residential & Commercial): Securely fastening corrugated sheets, standing seam panels, and metal tiles to steel or wood frames.
  • Pre-Engineered Steel Buildings (PEB): Critical for assembling industrial warehouses, factories, and aircraft hangars where structural strength is paramount.
  • Solar Mounting Systems: High-strength, corrosion-resistant stainless screws used to attach solar racking and PV panels to metal roofs.
  • Agricultural Structures: Ideal for barns, sheds, and poultry houses that require fasteners capable of withstanding ammonia and high moisture.
  • Wall Cladding & Facades: used for fixing insulated sandwich panels and exterior siding to building structures.

Q: What is the difference between a roofing screw and a standard wood screw? 
A: A roofing screw is engineered specifically for weather resistance. Unlike a standard screw, a roofing screw includes a bonded EPDM washer that creates a waterproof seal under the head. They also feature specialized coatings (like Ruspert or Galvanization) to resist rust from rain and sun exposure, whereas standard wood screws may corrode quickly outdoors.

Q: Do I need to pre-drill holes when using Fong Prean roofing screws? 
A: Generally, no. Our self-drilling (Tek) roofing screws are designed with a drill-bit tip that bores its own hole through metal sheets and purlins during installation. This saves significant time. For wood structures, our sharp-point screws pierce the wood easily without a pilot hole, provided the wood is not exceptionally hard.

Q: Can I get roofing screws painted to match my roof color? 
A: Yes! As a customer-centric roofing screw manufacturer, we offer powder-coated heads in a wide spectrum of RAL colors (Red, Green, Blue, Black, etc.). These painted heads blend seamlessly with your roof panels for an aesthetic finish and provide an extra layer of corrosion protection.

Q: Which material should I choose: Carbon Steel or Stainless Steel? 
A: For standard inland environments, coated Carbon Steel is a cost-effective and strong choice. However, for coastal areas (within 5km of the ocean) or highly corrosive industrial zones, we recommend Stainless Steel or Bi-Metal screws. Bi-metal screws offer the best of both worlds: a stainless steel body for rust resistance and a hardened carbon steel tip for drilling capability.
