• Square powder coated steel tubing for frames, uprights, and structural layouts

Built for Real-World Use

Raw steel tubing often requires additional steps—painting, coating, or plating—before it’s usable in visible applications. Our powder coated steel tubing eliminates that friction:

• Scratch- and chip-resistant finish
• Consistent color and sheen across runs
• Improved corrosion resistance versus raw steel
• Clean, professional appearance for customer-facing environments
