SMACNA Duct Manufacturing

We're Established

In 1997 we started as a small 2 man shop in Norco, CA. Today we employ many experienced sheet metal workers that are producing several million pounds of ductwork each year.

Outstanding Reputation

Although our business has grown significantly, we are still small enough to give the contractor personalized service and pride ourselves in customer retention.

Streamlined Ordering

If you have an approved set of shop drawings we can give you a complete price for the job straight away. We number every fitting on prints and put them on verified detail sheets. When it’s time to order, simply refer to the sheet, that’s it
