Building with Structural Cold Formed Steel (CFS)
What part of a project can you frame with CFS?
Everything. Yes, with Intellisteel you are able to design and build everything above the foundation, including roof trusses, floor joists, load bearing and non-load bearing walls.
Can Intellisteel can be brought in at any stage of any project?
Yes. Our system can improve everything from conceptual design to shop drawings, though we recommend Intellisteel be brought in early to work directly with the architect as Engineer of Record for best cost, schedule, material and weight reduction.
How do I get started with Intellisteel?
Step 1: Send Intellisteel a set of drawings/plans for any project in CAD or .dwg format, or Intellisteel consulting engineers can work directly with the architect.
Step 2: Intellisteel converts the project into CFS with its engineering software and provides a cost proposal.
Step 3: If accepted, that file is then sent to engineering for a final detailing and stamp.
Intellisteel’s consultant, engineering firm Martin and Martin, is licensed across the entire US, has 200 structural engineers on staff and has been engineering steel framing for more than 15 years.
How does using Intellisteel affect the project schedule?
With the speed of production and ease of assembly, the project schedule for framing is substantially reduced up to 50%. As a result of the process, other construction trade schedules are reduced since they are not required to punch holes, drill or cut anything on-site. Instead, they can work though Intellisteel’s pre-cut, pre punched, service holes.
Are there any limits to using CFS?
No. If it can be designed with CAD software, it can be built using Intellisteel. Since steel framing allows for larger spans in the design of the home, fewer interior load bearing walls are needed, making renovation very easy while allowing more flexibility in design.
Does your system meet US building codes?
Yes, all projects are designed to US building codes and current IBC standards.
Does your system account for local wind, snow and seismic loads?
Yes. All projects are designed to meet local wind, snow and seismic codes, even up to seismic 5. The engineering software accepts those inputs and converts the design to optimize the use of steel.
Are there fire and acoustical rated assemblies for your system?
How many floors can be produced with cold formed steel?
Economically, we suggest a maximum of about 10 floors, but from a design perspective the methodology can go much higher, though doing so may incorporate more steel. Contact your Intellisteel representative to discuss your specific project.
What materials can be used for cladding? is it different for CFS?
Anything. The same materials for cladding (interior and exterior) are used for timber, concrete and all other framing materials. In fact, a steel frame project will look exactly like any other project.
Does CFS hold up in different environmental conditions (humidity, heat, sea spray, etc.)?
All Intellisteel projects use galvanized steel coated material at varying degrees appropriate to the local environmental conditions. The non-combustible properties and strength of steel offer greater protection for homes, buildings or any project, and can eliminate high wind and lightning damage to your home. Galvanized steel will not crack, shrink, splinter, creep, split, warp, swell or rot, and it is impervious to termites and wood destroying insects.
Why would steel be better at limiting damage from lightning?
A steel frame actually allows more protection for the occupants of a home or building since it provides a direct electrical path to the ground. It also reduces the likelihood of explosions or secondary fire.
How does CFS hold up against earthquakes?
The use of positive connections and the inherent strength of steel provide the greatest protection against earthquake and hurricanes. The high ductility of light gauge steel make it the best construction material for earthquake resistant design.
Is Builders Risk insurance affected by using CFS?
Is steel recyclable?
Steel framing is the environmentally-friendly framing choice. When you compare that it takes 40-50 mature trees and only six scrapped cars to frame 2,000 square feet, you can quickly appreciate the value of steel today and the impact it could have on generations to come.
What is the environmental impact of steel?
The overall recycling rate of the steel industry is 66%, the highest of any industry in the world. Plus, steel framing scrap is a valuable commodity that will not end up in a landfill.
Can mold grow on steel framing?
No. Mold requires three things to grow: mold spores (which exist everywhere there is air), moisture, and organic material, which provides the food for mold. Steel does not contain any organic material, and therefore cannot support mold growth. However, if someone or something has left a residue of organic material on the steel framing, there is a chance that given the right conditions, mold could grow on the organic material, but it isn’t likely.
Won’t the steel frame rust?
No. The use of a zinc coating on the steel protects it from corrosion for the life of the structure.
