umbrella roofing nails
Crafted from high-quality Q195/Q235 carbon steel, these twisted shank umbrella roofing nails with washers are engineered for reliable roofing fastening, featuring hot-dip or electro-galvanized coating for exceptional corrosion resistance and long-term durability in outdoor and harsh weather conditions. The unique twisted shank design combines the driving ease of a nail with the strong holding force of a wood screw, creating enhanced grip in substrates to prevent loosening from wind, vibration, or temperature fluctuations . The umbrella-shaped head distributes pressure evenly, avoiding tearing of roofing materials, while the integrated washer (often rubber or metal) forms a tight watertight seal, effectively preventing water leakage and protecting the underlying structure .

The umbrella-shaped head is a standout feature, providing a larger bearing surface that distributes pressure evenly. This design effectively prevents cracking of roofing materials around the nail, ensuring the integrity of the roof structure. Additionally, the head adds a subtle decorative touch, enhancing the overall appearance of the roof.
For applications requiring extra stability, the twisted shank option offers superior holding power. It locks tightly into the material, preventing slipping and falling off even in high winds or vibrations, which is crucial for maintaining the roof's stability over time.
Thanks to the electro-galvanized surface treatment, these nails exhibit excellent resistance to rust and corrosion. This makes them suitable for both indoor and outdoor roofing projects, as they can withstand exposure to rain, humidity, and other harsh environmental factors, extending the lifespan of the roof.
Each nail comes equipped with a rubber or plastic washer that creates a tight seal between the nail head and the roofing material. This effectively prevents water leaks, protecting the underlying structure from water damage and mold growth.
These nails are highly versatile and can be used with various roofing materials, including asbestos tiles, plastic tiles, and metal sheets. Their design ensures a secure fit without damaging the fragile surfaces of these materials.
Beyond roofing, they are ideal for connecting wood components in roof framing and construction. The strong grip of the nails ensures that wooden structures remain firmly fastened, even under heavy loads.
Whether it's a residential roof, commercial building roof, or industrial facility roof, these nails perform reliably. They are suitable for both new roof installations and roof repair and maintenance work.
The electro-galvanized coating provides a long service life, typically lasting 10-15 years in normal weather conditions. In harsh coastal or industrial environments, their lifespan may be slightly reduced but still outperforms non-galvanized alternatives.
Yes, they are specifically designed for outdoor use. The galvanized coating and leak-proof washer make them highly resistant to rain, snow, and other outdoor elements.
