Black Steel Tubing - Powder Coated

Black Pre-Finished Steel Tubing

Matte Black Powder Coater & Cut to Size

This collection features pre-finished powder coated steel tubing, cut to your exact length and ready to use right out of the box. All tubing is cut and powder coated in house by Testrite, giving you the strength of steel with a durable, professional finish—without the delays and inconsistencies of outsourcing finishing.

We offer both round and square steel tubing, making this collection ideal for retail fixtures, displays, signage, frames, architectural elements, and fabricated components where appearance matters as much as performance.

This wholesale tubing is available direct from Testrite. Volume pricing is built right into our website, so the more you buy, the lower the price per tube.

What’s Included in This Collection

Round powder coated steel tubing in multiple diameters and wall thicknesses
Square powder coated steel tubing for frames, uprights, and structural layouts
Matte black powder coat as a standard stocked finish
Custom cut-to-length tubing, accurate to ±1/16"

All tubing is cut to size prior to powder coating, ensuring fully finished ends and a consistent appearance from end to end.

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
