Sinsun stainless steel coil nails, also known as steel wire coil nails, collated steel nails, or stainless steel coiled fasteners, are made from either 304 or 316 grade stainless steel. Your environment will determine which grade you choose. For most outdoor uses, 304 is great. 316 has molybdenum, making it more resistant to corrosion in saltwater. Both are solid stainless steel throughout, not just on the outside.
Another thing we've worked on is coil collation. If you've ever used cheap coil nails, you know how frustrating it is when the nails move in the coil, the wire tie breaks, and you have to clear a jam instead of driving nails. Sinsun coils are wound evenly, with even spacing and strong wire ties that can handle being moved around on the job site. They pass through your coil nailer smoothly, shot after shot, coil after coil.
We manufacture stainless steel coil nails in all the usual sizes and lengths, from 1-1/4 inch siding nails to 3-1/4 inch framing nails. Ring shank choices for the most effective holding power. Smooth Shank for everyday use. We also check every batch for hardness consistency and accuracy in size. You know what you're getting when you load a Sinsun coil.

Grades of Material:
304 Stainless Steel: Resistant to corrosion in most outdoor settings, including exposure to fresh water and general atmospheric corrosion.
316 Stainless Steel: Molybdenum makes it less likely to rust. It is recommended for places with saltwater, buildings near the coast within 1–2 miles of the ocean, and places where chemicals are present.
Choices for Shank:
Smooth Shank: Ideal for most uses, holds things well enough to be useful.
Ring Shank: Up to 40% more resistant to pulling out, perfect for siding and areas with vibration.
Details of the Collation:
Wire Coil: This is the standard for coil nailers and comes in 15° and 16° wire coil shapes.
Coil Diameter: Sizes that work with all major coil nailer brands.
Coil Count: The number of nails in each coil depends on the length and diameter of the nails.
Primary Uses for Stainless Steel Coil Nails
Stainless Steel Coil Nails for Coastal Construction
Stainless steel is not an option if you build near salt water. It is a must. Over time, the salt spray that blows inland for miles will ruin galvanized coatings, leaving you with rust stains and broken fasteners. Sinsun stainless steel coil nails, especially grade 316, can be exposed to saltwater for unlimited time. On the other hand, the construction next to them with galvanized fasteners shows rust within a few years. Stainless steel is the most effective insurance for beach houses, coastal decks, and marina buildings.
Stainless Steel Coil Nails for Fiber Cement Siding
Fiber cement siding is heavy, rough, and difficult to work with. It also gets thicker and smaller when the temperature changes, which loosens the nails. The most appropriate answer is Sinsun stainless steel coil nails with ring shanks. Stainless steel doesn't react with some siding materials and galvanized coatings, so it won't break down. The ring shank gives you the grip you need to stay still. And because they're all wire coils, installation is quick our team can sheath a whole house in a day without having to reload constantly. Professionals use stainless ring-shanked nails for fiber cement.
Stainless Steel Coil Nails for Marine and Dock Building
Building docks, piers, and boardwalks is challenging because they are always wet, salty, and subject to foot traffic. Regular fasteners break easily. This is exactly what Sinsun 316 stainless steel coil nails are made for. The molybdenum-enhanced grade is the most resistant to corrosion, and the coil collation makes it easy to build decking and framing quickly. It is only Sinsun stainless steel that is the right choice for commercial marinas, where failure means expensive repairs and liability. I've spoken with marine contractors in Scandinavia who refuse anything else.
Stainless Steel Coil Nails for Agricultural and Food Processing
Many people don't think about using this for agricultural buildings and food processing plants. In these places, moisture, cleaning chemicals, and humidity ruin regular fasteners. Stainless steel makes it impossible for food handling areas to rust. Stainless nails keep fasteners from breaking in livestock barns where animal waste makes ammonia that eats away at metal. This can cause structure problems. Sinsun stainless coil nails are used in dairies, processing plants, and agricultural buildings all over Europe and Asia. This is because they don't rust, stain, or break.
Real Customer Feedback
“
"Ten years in a beach house in Queensland - no rust in sight." "Not a single spot of rust." Ten years ago, we built a house on the beach in Queensland. We used Sinsun 316 stainless steel coil nails for every aspect, including framing, decking, and siding. Last month, I inspected it. There was no rust, no stain, and no popping heads. The place looks just like it did when we finished it. "The owner requested stainless steel, and Sinsun delivered."
“
"Our fibre cement crew switched to Sinsun stainless and never looked back." In the UK, we installed fibre cement siding on high-end homes. We had previously used galvanized materials for years, but sometimes it rusted. We then switched to Sinsun's stainless steel ring shank and coil nails. There is no rust on the ring shank, and even in bad weather, it stays tight. We experienced no jams or downtime when we fed coils through our guns. "Every penny is worth it."
“
Fasteners last only in dairy barns. "Sinsun stainless steel fasteners endure." Ammonia from animal waste corrodes regular nails. Every few years, we had to replace the siding. Five years ago, I started using Sinsun stainless steel coil nails. There is no rust, the siding remains tight, and there are no problems. The farmer is happy, and we're not coming back for callbacks.
“
We specified Sinsun 316 for a marina renovation. "Five years later, it's perfect." Theperfect." The deck of the marina in the south of France needed to be completely replaced. 316 stainless steel was required for everything. The Sinsun coil nails drove very well, and the crew liked how easily they fed. Five years later, with many tourists and constant salt exposure, every nail is still flawless. We will specify Sinsun again."
Frequently Asked Question
Q What is the difference between coil nails made of 304 and 316 stainless steel?
A: 304 is suitable for outdoor uses. 316 has molybdenum, which makes it more resistant to corrosion in saltwater. For buildings on the coast within a mile of the ocean, use 316.
Q Do stainless steel coil nails stick to magnets?
A: Most of them are magnetic because they were work-hardened during production. This doesn't change how well it works or resists rust.
Q Are stainless steel coil nails okay with pressure-treated wood?
A:Yes, stainless steel is the most suitable choice for treated lumber. Over time, modern pressure treatments eat away at galvanized coatings, but not stainless steel.
Q What size stainless steel coil nail should I use for fiber cement siding?
A: For fiber cement, a ring shank with 14 or 15 gauge is normal. The ring shank gives heavy siding materials the grip they require.
Q Do I need special tools to use stainless steel coil nails?
A: No, they work with regular coil nailers. Because the material is stiffer, you might need to apply more air pressure than carbon steel nails.
Q How long should a stainless steel nail be for decking?
A: For 5/4 decking (1 inch thick), 2-1/2 inch nails are long enough to go through. Go to 3 inches for thicker decking.
Q Do Sinsun stainless coil nails work with most major nailers?
A: Yes, our coils meet industry standards and work with all major coil nailers. Always check the fit by testing a sample.
Q How much holding power does an alloy ring shank have than a smooth one?
A: The ring shank is about 40% more difficult to pull out than a smooth shank of the same diameter.
Q Can you use stainless steel coil nails inside?
A: Yes, they are. They are too much for most indoor uses, but they work well in places with moisture, like pools, spas, and commercial kitchens.
Q What kind of packaging do stainless steel nails come in?
A: They come in plastic-wrapped coils and are packed in boxes by weight or count. For bigger projects, we can get bulk pallet quantities.
The Sinsun Promise: You Can Trust Stainless

The 304 and 316 materials used to make Sinsun stainless steel coil nails are certified.
The wire is always formed the same way, the heat treatment is just right, and the
collation is consistently reliable. They feed smoothly, drive straight, and last forever
in the most difficult conditions.
