Premium Umbrella Roofing Nails China Factory and Wholesale Suppliers
Our premium Umbrella Roofing Nails are engineered for superior structural fastening in construction, sand casting, and furniture repairing. Crafted from high-grade low carbon steel wire (Q195, SAE1008, and Q215), these nails feature a specialized umbrella head design that provides maximum surface grip and prevents pull-through, ensuring a secure and permanent hold in various wooden and roofing applications.
Designed for durability and versatility, our roofing nails are available in both smooth and twisted shank options to enhance withdrawal resistance. With advanced surface treatments including electro-galvanization and hot-dip galvanizing, these fasteners are built to resist corrosion and rust, maintaining structural integrity even in challenging environmental conditions. Certified by ISO9001:2000, we guarantee industrial-grade precision and reliability for every batch.

Frequently Asked Questions
The umbrella head provides a wider surface area that prevents the nail from pulling through the roofing material, offering significantly more stability and weatherproofing compared to standard nail heads.
For high-humidity or coastal areas, we recommend hot-dip galvanized finishes as they provide a thicker zinc layer and superior corrosion resistance compared to electro-galvanizing.
Yes, we offer various packaging options including plastic inside with woven bags, carton boxes, or specific weight boxes (e.g., 7lbs8 carton) to suit your retail or wholesale needs.
Smooth shanks are easier to drive in, while twisted shanks create more friction within the wood, significantly increasing the nail's pull-out resistance and overall grip.
Our typical delivery time is between 10 to 15 days after the deposit payment is received, ensuring your project stays on schedule.
Absolutely. Our production process is ISO9001:2000 certified, ensuring that all material grades (Q195, SAE1008) and dimensions meet strict industrial specifications.
