Tartan Bars - Unique Round Bar

Tartan Bars are produced by combining a preliminary forging process, which consolidates the center, with a planishing operation, which provides a smooth-rolled bar surface. At the heart of the operation is our custom-designed, computer-controlled GFM single-stand planishing mill. Through a series of reversing passes, the planishing mill rolls the bar to a smooth surface in less than 5 minutes.

While still hot, the bar moves down the GFM mill to the Braun abrasive saw station for trimming. A 16’ round can be cut in less than half a minute. To complete the process, the bar is end-stamped for traceability by an automated programmable marking system. The bar is then slowly rotated down an automatic uniform cooling bed to maintain straightness.

Since the bars can be produced so efficiently in the planishing mill, delivery times are reduced. Unlike traditional hot-rolled bars, which can only be manufactured in large runs, Tartan Bars can be purchased in quantities as small as the product of one ingot.

Tartan Bars versus rolled bars

• Rapid delivery—turnaround in 2-4 weeks (breakdowns even quicker)
• Custom sizes—6" to 16" in ferrous and non-ferrous grades
• High or low quantities—so you have better control over your inventory levels
• Competitive prices—due to the efficiency of our process
• Elimination of rejections—due to high-strength forged sound centers
• A perfect solution to meeting your breakdown or just-in-time customer requirements
• Improved straightness—1/8" in any 5` is standard; 1/16" in any 5` is available

Process highlights

As stated above, Tartan Bars^® are produced by combining a preliminary forging process, which consolidates the center, with a planishing operation, which provides a smooth-rolled bar surface. The rolling/planishing mill equipment used in the process includes:

• GFM horizontal rolling mill stand CCR 830 HP
• Braun hot abrasive cut-off saw
• Automated stamping system
• Cooling bed
