About Us

Modern Equipment and Technology

CNC Plasma Cutting

In 2018, we expanded our capabilities with a brand-new, 60,000-square-foot fabrication shop. It features excellent technology, including:

  • A 20-foot-long, coil-fed CNC plasma cutter.
  • A six-cradle coil line with lining capabilities.
  • A waterjet cutter for cutting HVAC duct liner.
  • A machine for forming spiral ducts.

The new facility has allowed us to automate fabrication and speed up production time. For example, the coil line is three times faster than standard ductwork production. We can also run the coil line and waterjet to produce ductwork and insulation simultaneously, dramatically speeding up the production process.

Our upgraded process allows us to produce custom HVAC products promptly. Whether you need fabricated custom duct, rectangular duct or spiral duct, we’ll maintain our renowned quality standards while efficiently completing your order.

Our swift HVAC duct fabrication ensures your business receives the piece it needs promptly, allowing you to leverage streamlined HVAC sheet metal fabrication near you.

Craig and his team always provide a high quality product at a fair price. Highly recommend if you are in need of the services they provide.
