Production CNC Machining and Custom Sheet Metal Fabrication in Northern California

Sel-Tech is a full service Production CNC Machining facility located in Chico, CA about 70 miles north of Sacramento in northern California.  We are also experts in custom fabrication of precision sheet metal and metal welding fabrication.  We are an FAA approved repair station for Airstair systems under aircraft quality specifications. The staff at Sel-Tech is well versed in the documentation requirements set forth by the MIL-I-45208a quality system. We are also able to turn-around precision prototype parts in a very expedient manner and at great pricing, to California, Oregon, Nevada or anywhere in the United States.

Sel-Tech is located in a 25,000 sq ft hanger located at the Chico Municipal Airport. This is our second move to a larger facility in the last 3 years, and we will be posting photos of our new facilities soon.

The business park is located within a Foreign Trade Zone, which saves on duties for manufactured products exported out of the country.

We have extensive selection of equipment for precision machining and custom sheet metal fabrication in our CNC machine shop.
