Can Metal Studs Hold Kitchen Cabinets?
Kitchen cabinets are an essential part of any kitchen. They provide storage space for dishes, food items, and cookware. Many homeowners opt for metal studs when constructing or remodeling their kitchens, which raises the question – can metal studs properly support kitchen cabinets? The short answer is yes, metal studs can be used to install kitchen cabinets securely. However, there are some important factors to consider.
Overview of Metal Studs
Metal studs are thin vertical framing members made of galvanized steel. They are an alternative to traditional wood studs used for framing interior walls and ceilings. Metal studs are lightweight, fire-resistant, do not warp or rot, and resist termites.
Some key advantages of metal studs:
- High strength-to-weight ratio – they can span longer distances than wood studs.
- Dimensional stability – they maintain their shape over time.
- Faster/easier to install – no need to cut or fit pieces together.
- Resist mold, mildew, and pests.
- Allow flexibility in design – can be curved or bent.
- Do not burn or fuel fires.
Using Metal Studs for Kitchen Cabinets
Metal studs are commonly used to frame kitchen walls, including walls intended for cabinet installation. However, there are some important considerations when using metal instead of wood:
Gauge
The gauge or thickness of the metal studs is important. 25-gauge studs do not provide adequate strength for cabinets. 20-gauge is better, but 18 or 16-gauge is ideal for robust cabinet support.
Spacing
Metal studs are often spaced wider apart than wood studs – up to 24 inches. For cabinets, it’s recommended to space metal studs 16 inches on center.
Backing
Since metal studs are hollow, they need additional backing at points of attachment. Horizontal bracing, blocking, or plywood sheets should be screwed between the studs where cabinets will be mounted.
Load Capacity
The lighter weight of metal studs allows them to span longer horizontal distances than wood before needing support. However, metal does not have as much vertical load capacity. Kitchen cabinets place a lot of downward weight that needs to transfer safely to the floor. Proper reinforcement is required.
Secure Attachment
Self-tapping screws are commonly used to attach cabinets to metal studs. Screws should be at least 1 inch long to fully penetrate the stud. Using washers provides extra holding strength. Attach screws to every stud, not just every other one.
Reinforcing Metal Studs for Cabinets
Here are some best practices for reinforcing metal studs for kitchen cabinet installation:
- Run horizontal bracing or blocking between all the studs where upper and lower cabinets will mount. These act as load-bearing “shelves”.
- Use thick plywood backing – at least 3/4 inch – screwed into place over sections of studs. This reinforces the area.
- Add wooden cross-supports between studs behind sink bases and other heavy cabinets for additional strength.
- Use toggle bolts anchored into the wall rather than just drywall screws when possible.
- Increase stud gauge thickness to 16 or even 14 gauge for heavy cabinets like floor-to-ceiling pantries.
- Reduce stud spacing to 12 or 14 inches on center rather than 16 inches.
- Install metal studs vertically rather than horizontally for maximum load capacity.
- Use L-brackets and metal corner studs to provide sturdy cabinet corners.
Installing Cabinets on Metal Studs
When ready to mount cabinets on metal studs:
- Locate studs using a stud finder suitable for metal. Mark locations.
- Drill pilot holes in the studs at cabinet locations to avoid screw slipping.
- Use self-tapping screws at least 1 inch long. Washers provide extra support.
- Secure every cabinet to every stud, not just every other stud.
- Level and shim cabinets to ensure they are plumb and stable.
- Use filler strips/spacers if a cabinet falls between studs. Secure to nearest studs.
- For wall cabinets, install extra metal studs or a mounting strip at desired height.
The Bottom Line
Metal studs are a suitable choice for kitchen cabinet framing and installation. However, proper planning and reinforcement is imperative to provide sturdy, long-lasting support under the considerable weight of kitchen cabinetry. Following the recommendations above for adequate gauge, stud spacing, backing, hardware, and mounting techniques will allow metal studs to reliably hold kitchen cabinets for years to come. With attention to detail, metal studs can be a high-performing building material for your kitchen project.
Frequently Asked Questions
Can you hang heavy cabinets on metal studs?
Yes, you can hang heavy cabinets like floor-to-ceiling pantries or large sink bases on metal studs, provided you take some extra steps to reinforce the studs. Use thicker gauge studs, add bracing and backing, reduce the spacing between studs, and be sure to attach into the studs securely.
How much weight can metal studs hold vertically?
An 18 gauge metal stud can hold up to about 265 pounds per linear foot vertically. A 16 gauge stud can handle around 375 pounds per linear foot. Sturdy reinforcement and careful installation allows metal studs to support the downward weight of cabinets loaded with dishes, equipment, and food.
Do metal studs need wood backing for cabinets?
It is highly recommended to install wood backing like plywood and horizontal bracing between any metal studs where cabinets will be mounted. The wood helps transfer the load and provides extra strength for secure cabinet attachment.
Should metal studs for cabinets be horizontal or vertical?
Vertical. Metal studs are stronger and more stable in the vertical orientation rather than horizontal. Vertical metal studs are the proper way to frame walls for securely mounting kitchen cabinets or other heavy fixtures.
Can drywall screws attach cabinets to metal studs?
Drywall screws alone do not provide enough holding strength for the weight of cabinets on metal studs. Use self-tapping metal screws that fully penetrate the studs. Add washers for extra support. Make sure to screw cabinets into every stud, not just alternating ones.
Conclusion
Installing kitchen cabinets on metal studs is certainly achievable with proper planning, materials, and installation techniques. Thicker gauge studs, adequate spacing, wood backing, strong hardware, and securing into every stud creates a framed wall that can reliably support the weight and use of kitchen cabinetry. Metal studs allow for faster, lighter construction and help resist damage from moisture and pests when done correctly. By following the recommendations in this article, metal studs can confidently be used to hold kitchen cabinets for the long term.
