ENGINEERING & DESIGN SERVICES
Steel stacks are among some of the tallest and most unique wind sensitive structures on Earth. They must be designed to survive maximum hurricane wind loads, severe dynamic vibration modes, and wind turbulence created by the wake from adjacent structures. Survival in active seismic regions and exposure to extreme ambient conditions are also critical parameters which must be evaluated in our external loading design analysis.
Having developed the most advanced analytical modeling capability for stack design in the industry, our engineers are committed to achieving ideal design solutions for all of your stack & chimney projects.

Regular inspections of power plant equipment play an important role in identifying potential maintenance and repair issues, and are key to performing repairs in a cost effective and timely manner. Inspections and maintenance are critical to the equipment as well as the safety of your plant personnel, as neglect may lead to severe deterioration and equipment failure.
Our experienced team of engineers and skilled construction experts have developed detailed inspection and maintenance programs for all types of stacks and chimneys. We’re able to evaluate the current condition of the structure to determine if the life of the stack can be extended, modified and utilized for another purpose, or if it needs to be demolished.
In addition to traditional stack inspection methods, we offer state of the art inspection techniques and services.
This method allows internal inspections to be completed while a unit is online, or when conditions are too hazardous or dangerous for personnel. The system is comprised of digital cameras which are enclosed and protected inside a thermally balanced housing which can take still photographs and HD quality video.
Thermal imaging works by detecting the heat signature being radiated by objects, and requires absolutely zero light. Since thermal imagers only look at heat, they are totally unaffected by light sources. Thermography is beneficial by reducing unscheduled outages, detecting problem areas more quickly without interrupting service, and allowing facilities to assess priorities for corrective action. This system also keeps the user out of danger, especially with live components that cannot be touched. Thermography does not intrude upon or affect the structure.
What We Inspect:
- Steel Stacks
- Concrete Chimneys
- Cooling Towers
- Solar Towers
- Other Associated Equipment
Turnkey steel stack fabrication
As the world’s largest full-service supplier of steel stacks, we offer complete turnkey services including custom steel stack fabrication services. We apply the industry’s most stringent quality control measures to ensure we deliver a consistent, quality product to our clients.
From regional fabrication facilities used throughout North America, to international facilities including Steelcon’s own workshops in Esbjerg, Denmark, and Kosice, Slovakia, we accept only the highest caliber of quality fabrication.
- Steel Stacks

Steelcon Fabrication Facilities
Steelcon’s workshops are equipped with state of the art equipment and are capable of producing industrial steel chimneys, steel liners, ductwork, and other related products for delivery worldwide. In total, Steelcon has 10,700m2 of production space and the capacity to operate 320,000 manhours per year.
- EN ISO 9001: Quality management
- EN 13084-7: CE marking of flue gas cores in the chimney
- EN 1090-1: CE marking of the hood on the chimney
- EN ISO 3834-2: Quality of welds in Esbjerg and Kosice, SK, respectively
- EN1090-2: Welding certificate
- DIN 18800-7 Class E Bescheinigung i or Esbjerg
Design & fabrication of liners and ductwork
Design & fabrication
Varying flue gas environments require the proper selection of materials to ensure the longevity of the entire stack structure. Your stack liner needs to protect your chimney or stack from high temperatures to maintain the integrity and lengthen the lifetime of the structure. We design, fabricate and erect new liners in addition to installing liner replacements.
Types of Liner Systems
We have designed and built hundreds of liner systems using various materials of construction including:
- Carbon Steel
- Stainless Steel
- C-276 Nickel Alloy
- Acid Block
- Borosilicate Glass Block
- Fiberglass Reinforced Plastic (FRP)
REPAIR, MAINTENANCE & RETROFIT SERVICES
Dominion E&C is the leader in the repair, maintenance and retrofit of deteriorated and damaged stacks and chimneys. We have developed a detailed program for classifying and categorizing maintenance and repairs. This program is individually applied to specific structures and tailored to each client by using a set of criteria developed by our team. This method allows us to provide our clients with efficient, cost-effective solutions that are well planned and properly executed. Life-cycle planning and cost/benefit analysis are factors we consider prior to recommending any repair or developing a maintenance program.
Our experienced crews, using highly specialized equipment, repair chimneys and linings of all materials including but not limited to steel, brick, concrete, and FRP.
Repair & Maintenance Services include:
- Temporary Stacks & Bypass Systems
- Linings & Internal Coatings
- Lightning Protection Systems (LPS)
- Electrical Systems
- Ductwork Construction & Repair
- Emissions Monitoring (Test Ports & Monorails)
- Access Systems (Platforms & Ladders)
- High Pressure Washdowns
