More about cold-formed steel structures

Galvanized steel is resistant to cracking, shrinking, splintering, creeping, splitting, warping, swelling, or rotting. It is also impervious to termites and other wood-destroying insects, ensuring long-lasting durability and reliability.

Opting for steel framing enhances your home’s safety and protection for your family. Steel’s robustness and non-combustible nature mitigate risks such as high wind, fire, and lightning damage, ensuring greater peace of mind for homeowners.

Steel framing emerges as the environmentally conscious option for residential framing. Considering that it takes only six scrapped cars, as opposed to 40-50 mature trees, to frame a 2000-square-foot home, the value of steel becomes evident today and for future generations.

With an overall recycling rate of 86%, the steel industry stands as the world’s highest recycling industry, presenting an environmentally responsible alternative for home framing. Steel framing scrap holds significant value as a commodity and should be diverted from landfills.

No, steel’s strength enables you to design homes with larger open spaces. With a steel frame, walls stay straight and true, allowing for finishing with any traditional materials.

Steel’s robust connections and inherent strength offer significant protection against earthquakes and hurricanes. A lighter structure with reinforced connections minimizes damage from seismic forces. Steel’s high ductility renders it the optimal construction material for earthquake-resistant designs.

Indeed, galvanized steel offers superior rust protection. Through sacrificial galvanic action, zinc can “heal” cuts, scratches, and abrasions in the steel. Given the rough treatment construction materials endure, including cutting, drilling, shearing, and fastening, the coating often gets scraped away. Galvanized coating outperforms enamel in effectively covering areas that are cut or scratched.

Indeed, a steel frame offers enhanced safety for occupants, providing a direct path to the ground in case of a lightning strike. This diminishes the risk of explosions or secondary fires.

No, the Healthy House Institute endorses steel framing for chemically sensitive and environmentally conscious homeowners who aim for excellent indoor air quality. Steel frames do not require termite treatment and are devoid of resin adhesives and chemicals typically found in other construction materials.

Technical & Structural

Engineers: Opting for cold-formed steel over traditional materials like wood provides engineers with unparalleled clean spans, allowing for larger rooms and open designs. Cold-formed steel panels also offer the advantage of being non-combustible, with a one-hour fire rating.


Contractors: Construction efficiency is significantly improved with cold-formed steel due to reduced on-site steel manipulation like drilling, cutting, or punching. Cold-formed columns and beams are easily movable and installable without heavy machinery. The minimal tool requirement streamlines the construction process. Moreover, the short training time for working with cold-formed steel facilitates quick adaptation, mitigating potential delays in foundation work. Additionally, the extensive pre-cut services minimize the need for complex follow-up trades.


Owners: Utilizing cold-formed steel enhances the marketability of projects by eliminating the need for numerous soffits, resulting in higher ceilings and more modern, spacious rooms attractive to potential tenants or buyers. Furthermore, cold-formed steel is more cost-effective than traditional steel or wood structures. The streamlined construction process reduces material usage and trade requirements, resulting in cost savings. The construction duration will be speeded, meaning you will have an early return on investment.

According to the IBC 2015 and earlier editions, Structural (Light Steel) Framing must adhere to coating standards outlined in AISI S220 and ASTM C955. ProSTUD (nonstructural) Framing must comply with coating requirements specified in AISI S220 and ASTM C645. These standards typically necessitate an ASTM A653-G40 coating or an alternative coating offering comparable corrosion resistance.

The American Iron and Steel Institute (AISI) issues the Specification for the Design of Cold-Formed Steel Structural Members, offering engineers and software developers a range of formulas to determine the load-bearing capacity of cold-formed steel framing components. Meanwhile, the American Society for Testing and Materials (ASTM) establishes the minimum and standardized material properties required for cold-formed steel framing. Additionally, ASTM furnishes fundamental guidelines or prerequisites for installing cold-formed steel framing elements.

The terms “33ksi” and “50ksi” denote the steel grade or yield strength, which measures material strength rather than stiffness or resistance to deflection. Typically, 50ksi material is preferred for high-load applications such as heavy floors, heavily loaded studs, and load-bearing headers. However, it is seldom necessary for curtain wall applications. In certain markets or specifications, 50ksi material may be mandated for material 16 gauge and thicker.

Given that steel studs or floor joists are integral components of wall or floor/ceiling systems, accredited testing agencies nationwide evaluate the fire resistance of actual wall and floor assemblies. These tests ensure that structural integrity is maintained even under fire conditions.

Lateral bracing is typically necessary in non-composite conditions, significantly above where the gypsum board ends or in walls where the gypsum board is applied to only one side.

Composite limiting height data is relevant for walls where the gypsum board covers both stud flanges for the entire wall height. Non-composite conditions are typical in all structures. When the gypsum board terminates at the ceiling level, but the stud extends to the deck, it constitutes a non-composite condition.

Curtain wall framing typically relies on attaching wall-facing materials to both sides of the studs for bracing. However, it’s essential to consider using these materials for bracing during construction. While sheathing is typically applied to the exterior of the studs, the inside flanges are often left unbraced until the interior is finished. Before interior board installation, high winds may cause stud damage due to the absence of interior bracing.


Steel strapping can be installed horizontally on the interior flanges, with a maximum spacing of six (6) feet in the center, in conjunction with the sheathing. This arrangement effectively braces and protects the stud framing during construction. Alternatively, if mechanical bracing is needed, it can take the form of steel strapping run horizontally on both sides of the studs and attached to each flange. Alternatively, the cold-rolled channel can be run horizontally through the stud punchouts and connected to each stud web. The maximum spacing for mechanical bracing of curtain wall framing is also six (6) feet in the center.

The lateral bracing of the top flange of floor joists is achieved by applying floor sheathing securely to the joists. The structural adequacy of the floor’s diaphragm effect must be assessed to ensure effective lateral bracing of the top flange. Additionally, joist bridging should commence and conclude with two (2) spaces of solid bridging. A repetitive pattern can be employed between these start and end points, consisting of five (5) spaces of strapping on the laterally unbraced flange followed by one space of solid bridging. The placement of joist bridging is as follows:


  • ⦿ For spans less than 14 feet, one row at the midpoint is required
  • ⦿ Two rows at third points are necessary for spans between 14 and 20 feet.
  • ⦿ For spans exceeding 20 feet, one row should be installed every 6 feet.

The national model building codes, such as the IBC and IRC, stipulate minimum required floor live loads (in pounds per square foot, PSF). For instance, residential applications typically require a 40 PSF floor live load, while offices necessitate a 50 PSF floor live load, and light storage areas mandate a 125 PSF floor live load.

In most cases, the top track lacks sufficient bending strength to support offset joists. However, suppose the joists must be offset from the load-bearing studs below. A structurally sound distribution member should be installed between the joists above and the load-bearing studs below. It is recommended to have the project engineer specify the distribution member system.

The criteria for designing the foundation of light gauge steel structures from a structural standpoint typically include considerations such as:


  • ⦿ Load Distribution: Ensuring the foundation is designed to evenly distribute the loads from the light gauge steel structure to prevent uneven settling and maintain stability.
  • ⦿ Soil Analysis: Conduct a thorough analysis of the soil conditions at the construction site to determine the appropriate type of foundation and account for factors such as soil-bearing capacity.
  • ⦿ Structural Compatibility: Ensuring that the foundation design is structurally compatible with light gauge steel structures’ specific characteristics and requirements.
  • ⦿ Building Codes and Standards: Adhering to relevant building codes and standards to meet safety and regulatory requirements, ensuring the foundation design complies with industry guidelines.
  • ⦿ Environmental Factors: Considering ecological conditions, such as seismic activity or high wind loads, and incorporating appropriate measures to enhance the foundation’s resilience.
  • ⦿ Material Selection: Choosing suitable construction materials for the foundation that align with the properties of light gauge steel structures and provide the necessary strength and durability.
  • ⦿ Foundation Type: Determining the most appropriate type of foundation, which may include options such as slab-on-grade, pier and beam, or strip foundations based on the specific needs of the light gauge steel structure.
  • ⦿ Expansion and Contraction: To prevent structural issues over time, it is important to account for potential expansion and contraction of materials due to temperature variations.
  • ⦿ Construction Methods: Selecting construction methods that align with the characteristics of light gauge steel, ensuring efficient and effective foundation installation.
  • ⦿ Professional Engineering Input: Involving structural engineers with expertise in light gauge steel construction to assess, design, and oversee the foundation, providing specialized insight for optimal performance.

Addressing these criteria can tailor the foundation design to meet the structural requirements of light gauge steel structures, ensuring stability, durability, and compliance with industry standards.

Designing a foundation for Light Gauge Steel Framing (LGSF) structures is crucial for several reasons. Firstly, it ensures the proper distribution of loads, preventing uneven settling and potential structural issues. Additionally, a well-designed foundation provides stability and support, enhancing the overall structural integrity of the LGSF building. Moreover, considering the lightweight nature of LGSF, a tailored foundation design accounts for specific load-bearing requirements and helps optimize the building’s performance, durability, and resistance to external forces such as wind and seismic activities. Overall, a meticulously designed foundation is essential for the safe and long-term functionality of LGSF structures.

ANS: Light gauge steel is significantly lighter than concrete, weighing around 5 psf (35 kPa) compared to the 30 to 70 psf (207 to 482 kPa) weight range of concrete. This allows for a potential reduction in the concrete required for foundations. It is crucial to inform your structural or foundation engineer about the specific loads on the concrete to ensure appropriate foundation design.

ANS: The type of footing or foundation commonly employed worldwide for light gauge steel frame structures is often shallow as the overall weight is significantly lower, eliminating the need for deep footings. Shallow foundations, such as slab-on-grade or strip foundations, are typically favored for LGSF structures due to their lightweight nature. These foundations distribute the loads evenly and provide stability without requiring extensive excavation or deep footings. Additionally, variations in local building codes, soil conditions, and specific project requirements may influence the choice of foundation type. Still, shallow foundations remain prevalent in constructing global light gauge steel frame structures.


Alternatively, consideration can be given to pre-cast footings based on budget and requirements.

ANS: Various methods exist for anchoring walls, and the choice depends on design and seismic loads. Anchor bolts and powder-actuated fasteners (PAFs) are the most prevalent. Design equations for anchor bolts are outlined in light gauge specifications and codes.

ANS: Steel frames offer an exclusive blend of strength and lightness, distinguishing them from traditional materials such as wood or concrete. The reduced weight imposes less stress on the foundation, minimizing the risk of cracks or settling over time. Despite its lighter characteristics, steel retains remarkable strength.
