Frequently Asked Questions

What is a Fire Trol Column?

A Fire Trol Column is a prefabricated, fire rated structural steel column designed to provide passive fire protection while maintaining an aesthetically pleasing finish.  Unlike field applied fireproofing systems, Fire Trol Columns are manufactured in a controlled facility and arrive on-site ready for installation.


What is the difference between intumescent paint/coatings and Fire Trol Columns?

Intumescent coatings are field applied that expand when exposed to high temperatures, insulating the steel during a fire.  They preserve the original shape of the structural member, but require careful surface preparation, controlled environmental conditions during application, inspections and ongoing maintenance.   Fire Trol Columns are factory-manufactured fire rated assemblies that arrive at the jobsite with the fire protection already incorporated.  Because the fire protection is completed in a controlled environment, these columns can help improve quality consistency, reduce field labor and minimize weather related installation delays.


How do you fire rate exposed structural steel?

Exposed structural steel can be fire-rated using several passive fire protection systems approved by building codes and tested assemblies including: Fire Trol Columns, Intumescent coatings, spray applied fire proofing, dry wall and concrete encasements.


What is the most cost effective way to fire rate exposed steel?

There is no single solution that is the most cost effective for every project.  You should consider the following while you evaluate your options: the desired appearance of your fire rated steel, the projects schedule, labor availability & maintenance expectations.


Can Fire Trol Columns qualify as AESS?

Yes.  Fire Trol Columns are designed to provide a finished architectural appearance suitable for projects where exposed structural steel is a key design feature.


How do Fire Trol Columns compare to concrete encasement?

Both systems provide passive fire protection, but they differ significantly in appearance, construction and installation.  Concrete encasements are poured onsite, increase the overall size of the column considerably, add weight and don’t tend to be aesthetically pleasing.  Fire Trol columns are fabricated off site, are slim in appearance, reduce field applied fireproofing and simplify coordination during construction.


How do architects specify Fire Trol Columns?

Architects typically specify Fire Trol Columns by identifying the required fire resistance rating, structural requirements (along with the structural engineer), finish, dimensions and applicable performance criteria within the project specifications and drawings. 


Why should architects choose the prefabricated Fire Trol column over field applied fireproofing?

Prefabricated systems arrive at the jobsite with the fire protection already incorporated into the assembly.  This can help reduce field applied fireproofing, improve quality control through factory manufacturing, minimize weather related installation delays, decrease waste and simplify coordination between trades.   Field applied systems, including spray applied coatings and intumescent coatings are installed after the steel is erected and may require additional inspections, environmental controls and extra coordination during construction.


When should Fire Trol Columns be considered during the design process?

The earlier the better.  Early coordination allows the architect, structural engineer and steel fabricator to integrate the required fire rating, structural design, connection details and architectural finish into a single coordinated solution.  This approach can reduce redesigns, minimize field modifications and improve constructability during installation.  Engaging the Fire Trol team during schematic design or design development can help identify the most efficient solution before construction documents are finalized.


What types of projects are best suited for Fire Trol Columns?

Typical applications include: airports, healthcare facilities, K-12 & Higher Education facilities, government buildings, courthouses, museums, prisons, corporate offices, mixed use facilities, convention centers ~ any place where your structural steel is architecturally exposed and requires a fire rating.


Are prefabricated fire rated columns UL certified?

Yes.  Manufacturers such as Fire Trol produce UL-certified assemblies that meet required fire-resistance ratings.


Can the columns remain exposed?

Yes.  The finished steel shell is intended to provide an architectural appearance suitable for exposed conditions.


Do they reduce field applied fireproofing?

Yes.  Because the fire protection is incorporated into the assembly, significantly less field-applied fireproofing is required.


Is there any field applied fireproofing required?

Yes – only the connection and the structural column at the connection site will receive field applied fireproofing.   The structural steel fabricator will apply this when they fire rate their decking, joists, etc.


What structural shapes are available?

Fire Trol offers Wide Flange, HSS and Pipe sections.


Can a 2-hour rated column be upgraded later, after the column has been erected?

No, changing the required rating after fabrication will require a new column.  Early coordination is very important.


Who determines the required fire rating?

The building code and project design team determine the required fire-resistance rating based on occupancy, construction type and location of the building.


Can the same structural steel column be used for 2-, 3-, or 4-hour ratings?

Yes. In many cases, the same WF, HSS or Pipe structural steel shape can be incorporated into different UL-certified fire-rated assemblies.  The required fire rating is achieved by the tested assembly design, not simply by the steel shape itself.


Why is it important to determine the required fire-rating early in the design process?

Selecting the correct fire-resistance rating during schematic design helps avoid redesigns, specification changes and coordination issues later in the project.  Early coordination also improves constructability and helps keep projects on schedule.


Do higher fire ratings always require larger columns?

Not necessarily.  The required fire rating is based on the tested UL assembly rather than the size of the structural steel alone.  Prefabricated fire-rated columns are engineered to provide the required fire resistance while maintaining a clean architectural appearance.


How are Fire-Trol® Columns tested for fire resistance?

Fire-Trol® Columns are manufactured to meet applicable fire-resistance requirements using tested and code-compliant assemblies. Fire ratings are established through recognized testing standards and are listed through UL (Underwriters Laboratories).


What fire-resistance ratings are available for Fire-Trol® Columns?

Fire-Trol® Columns are available with 2-hour, 3-hour, and 4-hour fire-resistance ratings to meet the requirements of a wide range of commercial, institutional, and public projects.

The required rating is determined by the building's occupancy, construction type, structural design, and applicable building codes. Fire-Trol manufactures each column assembly to match the project's required fire rating while maintaining an architecturally finished appearance.

Whether protecting columns in hospitals, schools, airports, government facilities, or office buildings, Fire-Trol provides fire-rated assemblies that combine passive fire protection with exposed structural steel aesthetics.


Can Fire-Trol® Columns be used in Type I and Type II construction?

Yes. Fire-Trol® Columns are commonly specified for projects utilizing Type I and Type II construction, where structural steel often requires passive fire protection to comply with the International Building Code (IBC).

Because every project has unique structural and code requirements, architects and engineers should verify the required fire-resistance rating and applicable UL assembly during design.

Fire-Trol works with the design team, structural engineer, and steel fabricator to ensure the selected assembly meets the project's fire protection requirements while supporting the desired architectural appearance.


How much larger is a Fire-Trol® Column than the structural steel it protects?

The finished dimensions of a Fire-Trol® Column depend on several factors, including the size and shape of the structural steel, the required fire-resistance rating, and the selected assembly.

Unlike field-applied fireproofing, which can create inconsistent thicknesses and irregular surfaces, Fire-Trol Columns are manufactured with a finished steel shell that provides consistent dimensions and a clean architectural appearance.

Because every project is unique, Fire-Trol can provide preliminary dimensions during the design phase, allowing architects and engineers to coordinate floor plans, curtain walls, ceiling details, and clearances before construction begins.


What finishes are available for Fire-Trol® Columns?

Fire-Trol® Columns are designed to complement modern architectural projects while providing durable passive fire protection.

Columns are typically supplied with a factory-applied primer, allowing them to be finish painted to match the project's architectural color palette. Depending on project requirements, additional finish options may also be available.

Because the exterior is fabricated from steel, the finished appearance offers clean lines and consistent surfaces that integrate well with architecturally exposed structural steel applications.  Carbon steel is the most popular steel used for the shell, but stainless is a gorgeous option for the right application.

Project-specific finish requirements should be discussed during the design phase to ensure compatibility with the desired aesthetic and performance expectations.


Can Fire-Trol® Columns be customized to match architectural designs?

Yes. Fire-Trol® Columns can be customized to support a variety of architectural and structural requirements.
Customizations may include different column shapes, dimensions, connection accommodations, and finish requirements to coordinate with the project's design intent. Whether the project calls for wide flange, HSS, or pipe columns, Fire-Trol works closely with the design team to develop a coordinated solution.
Early collaboration helps ensure the fire-rated assembly integrates seamlessly with surrounding architectural features while maintaining the required fire-resistance rating.

How are Fire-Trol® Columns installed on the jobsite?

Fire-Trol® Columns are delivered to the jobsite as prefabricated assemblies, reducing the need for field-applied fireproofing after steel erection.

Installation is coordinated with the structural steel erection sequence and project schedule. Because the fire protection has already been incorporated into the assembly during manufacturing, contractors can avoid many of the environmental and scheduling challenges associated with field-applied fireproofing systems.

This prefabricated approach can improve construction efficiency, reduce coordination between trades, and provide a consistent finished appearance throughout the project.
