Stronger Steel.
Triple Protection.
Built to Outlast.
From galvanized steel bollards to telescoping square tubing for signs and traffic control, our triple-layer coated products are DOT-approved and trusted nationwide.
Whether you need bollard tubing for parking lot protection or signpost tubing for public works projects, we deliver unbeatable quality that performs in the toughest environments.
Trust the Tubing Experts
Sonco’s steel tubing is engineered with three layers of corrosion resistance:
- Hot-dip galvanization (ASTM A-653 G-90)
- Conversion coating for added durability
- Clear organic topcoat to resist rust, weather, and wear
Combined with high-strength steel (Grade 50), our tubing provides exceptional load-bearing performance, whether it’s installed as a security bollard or a roadside signpost.
