When you’re putting up a pole barn that’s built to last, every little piece counts—right down to the screws. At DIY Pole Barns, we don’t skimp on the details, because we know that long-term quality depends on what goes into the build, not just what shows on the outside.
That’s why we stick with ST Fasteners’ ZXL screws for all our metal roofing, siding, and trim. These aren’t your run-of-the-mill hardware store screws. They’re tough, dependable, and made to handle years of weather without letting you down.
Sure, they cost a bit more than standard screws, but with UV-resistant washers, rust-fighting materials, and a 40-year warranty, ZXL screws are a smart investment. They’re just one more way we help make sure your barn is ready for the long haul.
Why Fasteners Matter—Not Just for Roofing, But for Siding and Trim Too
Fasteners might be small, but they play a huge role in keeping your metal siding, roofing panels, and trim pieces securely attached and protected from the elements.
Standard screws may be commonly used for metal buildings, but they’re often made from inferior materials that corrode, leak, or degrade over time. While they may be designed for metal roofing, siding, and trim, they simply aren’t built to last.
At DIY Pole Barns, we take a different approach—because DIY Pole Barns are designed for doers. People who build it once, build it right, and expect every component to hold up over time. That’s why we use ZXL screws: they’re engineered to outperform the rest and keep your structure solid for decades.
What Makes ZXL Screws Ideal for Roofing, Siding, and Trim?
ZXL screws are purpose-built for metal-to-wood fastening—perfect for metal roofs, siding panels, and trim details. Here’s why they’re the better choice:
1. 40-Year Manufacturer Warranty
ZXL screws are backed by a 40-year warranty against corrosion and washer failure, aligning with our metal roofing and siding panel warranties. That’s real peace of mind.
2. Superior Corrosion Resistance
The screw heads are made from a ZAMAC zinc-aluminum alloy, which resists rust even if the powder coating gets scratched during installation.
3. UV-Protected EPDM Washers
Each ZXL screw includes a premium EPDM rubber washer that’s UV-resistant and encapsulated to prevent drying, cracking, or shrinking—ensuring a tight, watertight seal that lasts.
4. Built Specifically for Roofing, Siding, and Trim
ZXL screws are engineered to secure your metal roofing panels, siding sheets, and trim pieces—the most exposed parts of your pole barn—against rain, wind, and heat for decades.
5. DIY-Friendly Installation
With self-drilling Micro-bit tips, ZXL screws go in fast and true, without slipping. They’re ideal for first-time builders and seasoned pros alike.
Why ZXL Screws Fit DIY Pole Barns’ Long-Term Vision
At DIY Pole Barns, we back our kits with a Limited Lifetime Warranty because we believe in building it right the first time. ZXL screws help us stand behind that promise.
Warranty Alignment
With ZXL’s 40-year warranty matching our metal panel warranties, you won’t have to worry about fasteners failing before the rest of your barn.
No Rust Streaks
Failing screws can cause ugly rust streaks down your siding and trim. ZXL’s corrosion resistance eliminates this risk—keeping your barn looking as good as it performs.
Long-Term Weather Protection
Between corrosion-resistant alloy heads and UV-stable washers, ZXL screws help your building hold up through storms, snow, sun, and more.
Why Standard Screws Don’t Cut It—Even If They’re Designed for Metal Buildings
Standard screws are often designed for metal roofing, siding, and trim, but design alone isn’t enough. Most are made from cheaper materials like painted or galvanized steel that degrade quickly in real-world conditions.
Where They Fall Short:
- Inferior Materials: Painted or galvanized screws rust when coatings wear off.
- No Warranty: Most standard fasteners come with no warranty at all.
- Low-Quality Washers: Washers dry out, crack, or shrink due to UV exposure, leading to leaks.
- Mismatched Lifespan: They often fail long before your panels do, forcing you into premature repairs.
That’s why we exclusively use ZXL screws—because DIY Pole Barns are designed for doers who don’t have time to fix fasteners that should’ve lasted.
