Ornamental Tubing(ASTM A554)

United Industries has produced stainless steel tubing to ASTM A554 specifications for over 80 years.

Our ornamental products are produced for a wide range of applications including tubing for mirror bracket arms, boat rails and ladders, washroom grab bars, swimming pool rails, medical equipment, automotive step bars and grille guards, among many others. All 300 series austenitic tubing is produced in the surface finish and packaging requirements specified by our customers.

Manufacturing

United Industries uses only raw material from approved steel suppliers for all of our ornamental ASTM A554 tubing, with specific Rockwell and surface finish requirements. Tube production is completed entirely in line, beginning with high quality roll form tooling that minimizes marking, laser welding, ID and OD weld bead conditioning, final sizing, cut to length, deburring, specified polishing, surface finish protection and packaging for shipment. This in line process keeps work-in-process problems to a minimum and reduces material handling.

Polishing

United Industries offers a wide variety of mechanical surface finishes, ranging from the 180 grit satin often used for washroom grab bars to the super-buff finish preferred for automotive accessory tubing. We also offer the highest quality as-welded surface for our customers who mechanically polish the tubing themselves or who have it electropolished. Our in-house sample electropolish testing tank ensures that you receive the surface condition required for these applications.

Quality/Testing

Our tube mill operators complete all required ASTM and customer specifications testing, based on fabrication and surface finish requirements. Mechanical tests are performed at regular intervals, and all tubing is 100% in line eddy current tested. If the tubing is to be mandrel bent, ID tolerances are critical. Therefore, plug gauges are utilized to ensure adequate clearance and customer-required dimensions are met. Mechanical polishing compounds and equipment are continually monitored using polished tube samples.

Product Delivery

A wide range of transportation options are available for fast deliveries across North America. United Industries’ JIT manufacturing capabilities allow us to accommodate fast order turnaround to meet customer requirements.
