1/2" OD Stainless Steel Pipe
- Bright Annealed Polished Sanitary Tubing ASTM A270
- Available in 316L Stainless Steel
- Stamped with Heat Lot Number
- Manufactured in accordance with 3A Standards for sanitary line process requirements
Tired of flimsy materials that rust or warp? Our 1/2-inch 316 stainless steel round tubing is here to upgrade your projects. Whether you’re fixing a boat railing, building custom furniture, or tackling backyard upgrades, this tube combines industrial strength with easy handling. Made from marine-grade 316 stainless steel, it laughs off saltwater, humidity, and harsh weather – perfect for coastal homes, RVs, or garage workshops.
Why You’ll Need It:
- Rust-Proof Superpower: Survives salty air, pool chemicals, and garden fertilizers.
- Easy to Customize: Cut, bend, or weld with basic tools (hacksaw, tube bender, MIG welder).
- Sleek & Professional: Polished or brushed finish – looks great on visible projects like bike racks or patio decor.
- No-Hassle Sizing: Pre-cut 1ft to 6ft lengths (or order bulk coils) – no need to wrestle with giant industrial pipes.
