Frequently Asked Questions
(FAQ’s)

No. Structural light steel framing members are coated with enhanced zinc and aluminum coating. Which protects the steel from corrosion.

Yes. Pictures can be hung from the drywell and heavier objects can be hung with self-tapping screws directly to the steel stud. Fasteners are available at any hardware store.

No. Waves pass through the space between the studs, as with conventionally built homes.

No. A steel framed building or home is 100% compatible with all standard building finishes. We will finish your home with exact interior and exterior finishes you would use for a traditionally constructed home/building.

Yes. Steel provides a safe path for lightning to travel directly to the ground with less resistance that can cause damage or a fire. Therefore, steel offers more protection than a conventional building.

Cold formed Steel shapes can be used for roof systems, floor systems, wall systems, roof panels, decks, or entire buildings. They can also be used as individual framing members such as studs, joists, headers and truss members. Cold formed steel members can also serve as both primary structures and secondary structures. An example of the Cold Formed Steel used as primary structure is the LSF Studio webbed trusses. Steel studs can also act as secondary structures by providing lateral support to exterior wall finish since they rely on the primary structure for support.

There are many differences between cold framed steel and hot rolled steel:

  • Cold-formed steel (CFS) is typically limited to light thickness (up to 3.00 mm) while hot rolled steel can be manufactured to any desired thickness.
  • CFS shapes are different than hot rolled shapes and endless geometrical shapes can be produces.
  • CFS is manufactured at room temperature while hot rolled steel is made at elevated temperatures.
  • CFS lightweight makes it easier and more economical to mass-produce, transport and install.

Several 8 storey building has been constructed in the USA and Europe using cold formed steel framing. The first 8 story building in the USA built with steel framing was completed in 1999 in Seattle, Washington (a high seismic area). Mid-rise building (5 or 6 levels) in cold formed steel are also very common and many have been built around the world in the past 20 years or so. From an engineering point of view, there is no limit on the number of storey’s that can be built with cold-formed steel framing.

One of the biggest advantages of cold-formed steel is its high strength to weight ratio. This allows manufacturers and framers to fabricate long trusses with clear spans up to 26 meters. Steel trusses can be easily designed with clear spans up to 14 meters. Beyond that, a thicker material or boxed profile would be required along with specially designed connections. (Note: In many areas, there are transportation limitations when truss span exceeds 15 meters). For long trusses, intermediate bearing supports can also be used to reduce the size and thickness of the truss members.

Cold-formed steel is much lighter than concrete. It weights approximately 5 psf (0.24kPa) while concrete ranges from 30 to 70 psf (1.45 to 3.35 kPa). In most cases, using cold formed steel means that amount of concrete used in the foundations can be reduced. Your structure or foundation engineer should be made aware of loads acting on the concrete so that the foundations can be designed accordingly.

The future of construction lies in sustainable materials, that are delivered using fast modern methods. Cold Formed Steel can result in faster build times, lower costs, versatile design solutions and a durable, practical solution to premium buildings.

The Design-Led process reduces costs, including engineering, skilled labour and increases productivity efficiencies giving an overall greater return on investment.

Using the LGSF Design and Engineering software and Equipment there, are significant speed advantages which often result in the delivery of the overall project being cheaper. These costs vary from region to region and also based on the cost of various cladding materials, insulation materials and finishing materials.

When cladding and lining CFS walls it is important to follow the supplier’s installation guidelines and the recommended fastener spacings. MDF also recommends the use of a suitable adhesive between the lining sheet and the steel stud. The adhesive is applied in a coin size daub between the fasteners. This has many benefits to the structure and helps prevent any noise created when tapping the lining sheet. On any wall where either a glass wool or rockwool insulation is installed it is important that the whole cavity is filled, always specify a product that is the same thickness as the frame width. Our Field Construction Experts can guide you on this.

MDF recommends high quality steel from trusted steel mills globally. All steel products conform to internationally approved standards and specifications that ensure quality constructions.

No. Because of steel’s strength you can design your home with larger open spaces. With a steel frame, the walls will remain straight and true and can be finished with any materials that are traditionally used.

Design requirements are different depending on building type and geographic location. Talk to one of our experts to find out the production speed and costs for your building.

Yes - buildings up to 10 storey’s can be built faster and more efficiently than using traditional structural steel or concrete.

Galvanized Cold Formed Steel will not crack, shrink, splinter, creep, split, warp, swell or rot. Steel is impervious to termites and wood destroying insects.

Steel’s strength and non-combustible properties offer greater protection for your home and family. Choosing steel-framing can eliminate high wind, fire, and lightning damage to your home.

Steel framing is your environmentally friendly residential framing choice. In comparison it takes 40-50 mature trees versus six recycled cars to frame a 200 square meter home. You can quickly appreciate the value of steel today and the impact on generations to come.

The overall recycling rate of the steel industry is 86%, the highest of any industry in the world. This offers an environmentally sound alternative for framing. Recycled framing is a valuable commodity that typically does not end up in a landfill.

Steel framed walls are unaffected by temperature or humidity changes, more of the heating and air-conditioning cost remain inside the house, saving money spent on utility bills.

Positive connections and the strength of steel provide great protection against earthquake and hurricanes. A lighter structure with stronger connections results in less damage from seismic force. Steel’s high ductility makes it the best construction material for earthquake resistant design.

Yes, galvanized steel provides better rust protection. The reason is that zinc, through its sacrificial galvanic action, can “heal” cuts, scratches and abrasions in the steel. With the rough handling that construction products receive, as well as the cutting, drilling, shearing and fastening of members, the coating gets cut and scraped away. The galvanized coating works better than the enamel at covering areas that are cut or scratched.

No. Steel framing is recommended by the Healthy House Institute for chemically sensitive and environmentally conscious homeowners who seek good indoor air quality. Steel frames do not need to be treated for termites and are free of resin adhesives and chemicals normally present in other construction materials.

No. A steel frame home will look exactly like any other home. The same exterior finishes can be applied to a steel frame as those applied in standard construction.

Yes. Since steel framing enables 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.

No. The use of zinc coating on the steel framing protects the steel from corrosion for the life of the structure. Also the Steel is completely covered with insulation and cladding materials.

Yes. A steel frame actually allows more protection for the occupants since it provides a direct path to the ground in the event of a lightning strike. This reduces the likelihood of explosions or secondary fire. More safer than Conventional structures.
