10-12 Heavy Gauge Steel Studs: Supporting Taller Multi-Story Buildings
When it comes to constructing taller multi-story buildings, 10-12 gauge studs can often be utilized on lower floors to optimize for material cost. While they present challenges both in handling and installation, their superior strength makes them high performers for particularly demanding projects. This article explores the notable characteristics, applications, and best practices for working with 10-12 gauge steel studs.
Reasons to Choose 10-12 Gauge Steel Studs
Metal Stud Gauge Colors and Thickness
| Gauge | Thickness (mils) | Color |
|---|---|---|
| 10 | 118 mils | Blue |
| 12 | 97 mils | Red |
| 14 | 68 mils | Orange |
| 16 | 54 mils | Green |
| 18 | 43 mils | Yellow |
| 20 | 33 mils | White |
| 20 non-structural | 27 mils | Pink |
| 25 non-structural | 25 mils | Black |
10-12 gauge steel studs are thicker and heavier than the more common 14-18 gauge alternatives. Their increased thickness allows for greater vertical load bearing capacities, leading them to be utilized as load-bearing studs for the lower floors of 5 to 10+ story buildings. The key performance metric engineers use is combined axial and lateral loads. Combined axial and lateral loads on a metal stud occur when it simultaneously experiences vertical compression (axial load) from elements above and horizontal forces (lateral load) like wind. This combined loading creates a realistic stress scenario, requiring engineers to consider both buckling under compression and deflection from lateral forces. The table below shows the combined axial and lateral load baring capacity on studs and how they increase when you increase the gauge.
As you can see a 18 gauge 800S162-43 can bare 1.51 Kips(1,510 lbs) in the axial directions before integrity is compromised and the stud gets in risk of failure. While the same profile 10 gauge stud(800S162-118) can hold more than 8 times is 18 gauge counterpart: 12.86 kips. And the 10 gauge stud is only about 3 times as thick as an 18 gauge stud, meaning it only uses 200% more material achieve 8 times the load baring capacity. This is key for supporting buildings reaching heights in the 7 to 10+ story range. providing greater structural integrity in regions prone to earthquakes or high winds. Other advantages include enhance performance with superior resistance to seismic base shear, lateral loading, uplift capacity.
Ideal use of 10 or 12 gauge studs in multi-floor buildings
When building multi-floor structures you can often minimize the total amount of steel in the building by using it 10-12 gauge studs on the lower floors. Engineers usually see a great return on their projects at around 5-10 floors when designing in LGS. An optimized example schedule for a 8 floor hotel might look like this:
| Floor | Stud / spaced at 24 O.C |
| 1st Floor | 600S200-97 |
| 2nd Floor | 600S162-97 |
| 3rd Floor | 600S162-97 |
| 4th Floor | 600S250-68 |
| 5th Floor | 600S162-68 |
| 6th Floor | 600S200-54 |
| 7th Floor | 600S162-54 |
| 8th Floor | 600S162-43 |
Challenges in Working with Heavier Gauge Studs
Manufacturing and Handling
Producing 10-12 requires specialized machinery and additional labor due to their thickness. On the manufacturing side, this typically means that these heavier gauge studs are produced on dedicated production lines. Making them difficult to find in rural areas are not frequently stocked by supply houses. Using them on a project requires planning well in advance.
On-site, their weight and rigidity can complicate handling, requiring careful planning, equipment allocation, and sufficient manpower.
Cutting Techniques
Cutting 10-12 gauge studs efficiently requires the right tools. Metal chop saws are ideal for high-volume cutting, delivering precise, straight cuts but generating noise, particulate, and fumes. Handheld metal circular saws and band saws offer flexibility for on-site custom cuts, including custom angles, which can be fine-tuned with an angle grinder. For precision tasks like curved cuts or tight radii, nibblers and double-cut shears excel, while single-cut shears are better for straight cuts or broad curves. Also note that nibblers in particular produce large quantities of sharp waste material on the ground. Make sure to purchase heavy duty models of these tools that are capable of handling thicker gauge material.
Joining Methods – Fasteners
It is difficult to drill into 10 and 12 gauge studs requiring pressure and time. Framers typically budget more time per floor on these builds. You must used specialized screws for fastening heavy gauge metal. With features such as fine threads for enhanced tensile strength & a hex head washer to allow for superior grip. This is a screw that works for metal up to 3/8″ thick.
Joining Methods – Welding
Welding is frequently specified for additional strength at key connections such as door jack studs, pony wall anchors, and many exterior framing joints. When feasible, proper edge preparation, such as grinding away the galvanized coating, is nice for consistent weld quality. Stick welding and flux core wire are both possible. Make sure to practice welding thinner materials as it is possible to burn through and create holes. Because 10 gauge (118 mils) studs are almost ⅛” thick it is much more manageable and forgiving when welding heavier gauge CFS framing as compared to standard gauge thicknesses. Make sure to follow all joining specifications in construction details that are prepared by your project’s structural engineer.
Applications and Benefits
The use of 10-12 gauge steel studs is ideal for projects requiring increased building heights, allowing for greater design flexibility and expanded usable space. They also can enhance structural performance, making them useful for buildings in seismic zones or those subject to high wind loads. Their long-term durability is a key consideration for commercial and institutional buildings with a long projected lifespan.
Final Thoughts
While 10-12 gauge steel studs demand more effort and technical expertise, their advantages in enabling taller, stronger, and more resilient structures are undeniable. For construction professionals looking to push the boundaries of design and performance, these studs can be a powerful tool for expanding your technical capabilities and repertoire.
