Sheet metal fabrication
The automated sheet metal shop connects CAD drawings with coil-line and plasma-cutting equipment to prepare ductwork and project-specific metal components.
- Project-specific ductwork
- Galvanized, aluminum, stainless steel and copper
- Roof curbs, pipe stands, plenums and fan housings
- Specialty and heavier-metal fabrication

How CAD information becomes project-specific ductwork and components.
CAD-connected shop production
Blume’s sheet metal shop uses an Iowa Precision coil line and plasma cutter. Downloadable information from the CAD department connects the coordinated drawings directly with fabrication equipment.
Prepare a clean product for the field
Ductwork is wiped down and covered at both ends before delivery. Shop preparation, prefabrication and storage are coordinated with the requirements of the installation team.
Fabricate for the project
Fabrication capabilities include galvanized steel, aluminum, stainless steel and copper. Alongside ductwork, the shop produces specialty items such as roof curbs, pipe stands, plenums and fan housings.
Specialty metalworking capability
Ironworking capabilities support components that require heavier steel and metals. Share the material, dimensional and project requirements with the team to establish the proposed fabrication scope.
