FAQ

Frequently Asked Questions

What types of industrial ductwork do you fabricate?

We fabricate all types of industrial ductwork including process ducts, exhaust ducts, ventilation systems, high-temperature ducts, and corrosion-resistant ducts. We work with rectangular, round, and custom configurations including transitions, elbows, and specialty fittings.

Can you repair existing ductwork on-site?

Yes, many ductwork repairs can be performed on-site including patching, section replacement, reinforcement, and support repairs. Our mobile crews are equipped for field repairs during shutdowns or emergency situations.

What materials do you use for duct fabrication?

We fabricate ductwork from carbon steel, stainless steel (304, 316, etc.), and specialty alloys depending on application requirements. Material selection considers operating temperature, chemical exposure, abrasion, and structural requirements.

Do you provide stack inspection services?

Yes, we provide stack inspection services including visual inspection, thickness testing, and structural assessment. Inspection reports identify areas of concern and provide recommendations for repairs or replacement.

How do you handle large ductwork installations?

Large ductwork installations are carefully planned with modular fabrication, proper rigging, and coordination with plant operations. We work with plant personnel to schedule lifts and connections to minimize disruption.

Can you fabricate replacement sections to match existing ductwork?

Yes, we can measure and fabricate replacement sections to match your existing ductwork. This includes matching dimensions, material, and connection details for seamless integration with your current system.
