The Streimer fabriduct line was installed in mid-2001.

saves time.

Streimer maintains one of the few fabriduct lines in the Northwest that accommodates both five- to six-foot joint lengths. By running six-foot lengths rather than five-foot lengths, there are fewer joints to assemble, which saves substantial field labor. Running six-foot joints also enables Streimer to produce more pounds of duct material per hour and offer very competitive pricing. What's more, the Streimer fabriduct line automates several key processes, which saves time, further reducing costs.

Here's how a typical job goes through the Streimer fabriduct line:

Six coils of steel in varying gauges are prestaged and ready to roll. The machine operator retrieves the appropriate-sized coil for the job, the steel goes onto a loading table, and then it runs through the leveling rollers. If rectangular duct is produced, beads may be added, as well as tie-rod holes and notches for end connectors.
   Next, the shearer automatically cuts the duct material, based on coordinates pre-keyed into the machine's computer. Rectangular duct goes to a transfer table, where it is turned 90 degrees for long seam forming. Snap-lock or Pittsburgh seams are applied, followed by auto sealant.
   Once end-joint connectors are added, sound attenuation lining is applied, pins are welded automatically, and finally, the duct is braked into an "L" shape or a one-piece wrapper.

All duct work is
finished to SMACNA or job specific guidlines.
