SI Mechanical, LLC moved its fabrication to its new 24,000 SF facility in 2020. Since that time, we have added more automation and more equipment to improve quality and production. The facility was constructed with sheetmetal and piping production in mind. Our facility has the ability to store large amounts of raw materials to maintain high production levels as well as staging for constructed materials while waiting to load and ship. Our ductwork and products are hand-built to the highest standards and we always follow SMACNA standards in our duct construction.
SI Mechanical LLC sells fabrication to the public. We can make small orders in a few days or we can bid your plan and spec projects. SI Mechanical, LLC will package and ship the pieces you want, when you want them. We build sheetmetal specialties and air duct accessories in house.
