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
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.
