When we say “we’ve been installing piping forever,” we mean it. In fact, we installed our first pipe when we opened our doors in 1920. In the years since, we’ve developed one of the largest piping and fabrication shops in the Northwest.

These systems are almost limitless in their applications and possibilities. At their most basic, they help heat and cool the buildings we work and play in every day. At their most complex, they are the intricate nervous system that powers manufacturing, healthcare, and data centers.

Hydronic Systems
Hydronic systems heat or cool a building. While piping is still essentially the same as it was in the 1920s, the recent push towards sustainability has created a renewed interest in these systems for their efficiency and flexibility. The chilled water and heated water systems of yesterday are now being used in close conjunction with heat recovery systems, geothermal loops, phase-change materials, chilled beams—the list goes on and on. Even steam systems are making their way back into the mainstream these days.

Part of the challenge with hydronic systems is their higher cost. We work continuously to find ways to reduce cost, improve quality, and decrease waste with our heavy emphasis on fabrication.

This allows for:

  • Pre-fabricated mechanical rooms
  • Pre-manufactured hydronic coil assemblies
  • Equipment skid fabrication
  • Piping fabrication
  • Tank fabrication
