In addition to producing routine dimensional tolerances of ±0.010" and standard finishes, we offer customization to meet the technical specs and aesthetic requirements of any job, as well as new or special applications:

• Centerless grinding to tighter tolerances — as low as ±0.002"
• Multiple finish options for plating mild steel
• Electropolishing to give stainless-steel tubes an extremely durable, high-quality finish
• Powdercoating in a wide range of colors to give your next product a more dramatic look
• Tumbled de-burring
• Grit blasting

• Straight Weld
• Spiral Weld
• Spiral Welded Louvered

Relating perforation patterns to open area hole size is usually determined by the minimum size of the particulate that is to be trapped. However, the pressure drop across the tube is a function of open area, which the process designer must determine for each individual application.
