Condition & Edge Quality
- Surface Condition: Brand new, clean raw steel. The cold-rolling process guarantees a smooth finish completely free from heavy mill scale, meaning you spend less time grinding down to clean metal and more time under the hood. A light film of rust-preventative oil may be present to keep the surfaces pristine during shipping.
- Edge Quality: Every coupon is mechanically squared and sheer-cut. Because they are never plasma or laser cut, they carry zero thermal dross, slag, or heat-affected edges. They are clean and ready to butt up, lap, or corner-weld straight out of the box.
Ideal Applications & Uses
Our 18-gauge steel coupons offer stable heat dissipation and are perfect for dialing in machines or running practice beads. They are highly sought after for:
- Welding Practice & Education: Excellent for student training, vocational schools, and DIY garage hobbyists practicing MIG, TIG, Stick, or Gas welding.
- Machine Calibration: Perfect for testing settings, wire speed, gas flow, and heat penetration before working on expensive structural car panels or finished projects.
- Small Fabrications: Can also be utilized as backing plates, custom reinforcement tabs, small mounting gussets, and shim stock.
Shipping & Packaging
The 12-pack of coupons is securely bundled and shipped flat inside a heavy-duty, moisture-resistant protective bubble poly mailer to ensure safe, dry, and dent-free transit to your shop. This listing features free shipping with a reliable 2 to 4 business day domestic delivery window.
