Installing cabinets on metal stud walls requires some special considerations compared to mounting them on wood stud walls. With proper planning and materials, you can securely install cabinets on metal studs for a functional and attractive result. This comprehensive guide covers everything you need to know for a successful metal stud cabinet installation.
Introduction
Metal studs offer several advantages over traditional wood studs, which is why they are commonly used in commercial and residential construction. Metal studs are lighter, stronger, non-combustible, and resistant to warping or rotting. However, their thin gauge and lack of solid anchoring surface present challenges when installing heavy cabinets or items.
With metal studs, you cannot simply screw cabinets into place like you would on thicker wooden studs. Proper anchoring points need to be created to securely support the weight. Various specialized fasteners, backing boards, toggles, and braces can be utilized depending on the specifics of your install.
By taking the time to properly plan the cabinet layout, gather the right materials, and follow installation best practices, you can end up with a metal stud cabinet mount that is actually stronger and more durable than a basic wood stud setup.
Benefits of Installing Cabinets on Metal Studs
While it may seem easier to utilize wood studs, there are several good reasons to stick with the existing metal stud framework:
- Strength – Properly installed metal stud cabinets can be stronger and more secure than wood stud versions. The metal itself does not compress or warp.
- Fire safety – Metal does not burn or enable flames to spread like wood studs. This added fire resistance is ideal for kitchens.
- Professional finish – Metal studs allow for a clean, uniform look, without irregular wood grains or knots showing through cabinetry.
- Versatility – Metal studs are ideal for safely supporting heavy upper cabinets loaded with dishes, appliances, etc.
- Durability – Metal studs will not rot, warp, or become compromised over time like wood can.
By utilizing the proper installation techniques, you can take full advantage of the benefits of metal studs when mounting cabinets securely.
Cabinet Installation Considerations
Installing cabinets on metal studs is definitely more involved than just screwing them into wood studs. Here are the main factors to consider:
Cabinets Will Not Anchor Directly to Studs
Do not attempt to secure cabinets directly against metal studs with screws or nails. The thin gauge of the metal will not hold anchor points securely. The studs may become warped or damaged as well.
Backing Boards Provide Solid Anchoring Surface
Typically, a backing board is attached across the metal studs first to create a solid surface to mount the cabinets against. Plywood and horizontal boards are commonly used.
Weight Load Must Be Properly Supported
Heavy upper cabinets will require additional supports like vertical bracing or metal brackets anchored into the studs via toggles.
Layout Should Align With Studs
Planning cabinet placement to align with the metal studs’ exact locations provides the most secure mounting points.
Specialty Fasteners Are Required
Self-tapping metal screws, bolts with toggles, and heavy duty metal cabinet hanging rail kits are needed to anchor into the metal studs or backing boards.
With smart planning and preparation, these factors are easily addressed!
Step-by-Step Guide to Installing Cabinets on Metal Studs
Here is a step-by-step walkthrough on how to properly hang and secure cabinets onto a metal stud framework:
Step 1 – Map Out the Studs
Use a stud finder to locate all the metal studs within the installation area. Mark their exact locations with tape or permanent marker.
Also indicate plumbing lines, electrical wiring, and any other potential obstructions. Knowing the exact stud positions will allow you to optimize the cabinet layout.
Tip: Double check measurements since stud finders can be inaccurate on metal.
Step 2 – Plan the Cabinet Layout
Using the marked stud locations, plan where you want to position each cabinet section. Mark these clearly as well.
Try to align at least 2 points of each cabinet over studs to provide the most secure attachment. Having cabintes between the studs is also okay if anchored properly.
For upper cabinets, make sure the unit aligns with a stud where you plan to attach hanging rails or other supports.
Step 3 – Install Backing Boards
Most often, plywood boards are screwed horizontally across the metal studs to create a solid mounting surface.
Cut boards to length and attach them by driving self-tapping screws at least every 12 inches into the studs. Stagger them to avoid tensions.
Make sure boards line up with your cabinet layout’s anchoring points. You can also use vertical boards for specialty installs.
Step 4 – Attach Cabinet Hanging Rails
Install any specialty hardware like hanging rails, brackets, or supports according to the manufacturer instructions. These provide attachment points for upper cabinets.
Rails mount to the backing boards or directly into studs. Use the proper type of lag screws or toggles to securely anchor the hardware through the thin metal.
Reinforce with extra screws, and make sure weight will be directly transferred to the studs.
Step 5 – Mount the Cabinets
You are finally ready to mount the cabinets onto the prepared metal stud framework.
For lower units, screw through the cabinet backer board directly into the plywood backing or studs it aligns with. Use 2-3 screws per attachment point.
For uppers, set units onto the hanging rails or supports first. Then drive screws through the top and sides at stud locations to fully secure.
Do not rely solely on hanging rails to support weight long term. The unit must fixed directly to studs as well for maximum security.
Step 6 – Install Shelves and Adjust Doors
Once cabinets are mounted, you can install any included shelving, adjust doors, attach knobs and handles, etc. according to the manufacturer’s instructions.
Double check that all units are solidly fastened and do not rock or shift when opening doors or accessing contents. Resecure any problem areas.
Then load everything up and enjoy your new metal stud mounted cabinets!
Tips for a Secure Installation
Here are some additional tips for achieving the most secure metal stud cabinet installation:
- When possible, stack upper cabinets directly over lowers to transfer weight directly to the floor.
- Use cabinet screws designed for metal that self-tap and drive in easily. Standard wood screws can snap.
- Look for stud conflicts before building cabinet boxes. Adjust heights or widths if needed.
- Shimming behind cabinets may help reduce vibration or noise from thin metal studs.
- Caulk well during and after install to prevent cabinet movement and provide a cleaner finish.
- Consider hiring a professional if you are uncomfortable with the specialized hardware or fasteners.
Common Questions
What type of screws should I use?
Self-tapping metal screws are ideal for attaching boards or hardware to metal studs. For mounting cabinets, coarse threaded lag screws give the best hold.
Do I need to add horizontal cross braces?
For extremely heavy upper cabinets, diagonal cross braces can help strengthen the metal stud framing. Consult a structural engineer for recommendations.
Can I hang a cabinet between two metal studs?
Yes, use toggle bolts secured in the wall cavity to anchor the cabinet at multiple points to the surrounding studs.
Should I glue cabinets as well?
Construction adhesive can provide an extra layer of security between cabinets and backing boards. Just avoid excess squeeze out.
How do I reduce cabinet vibration on metal studs?
Fully securing cabinets, using sound dampening backing board, adding insulation, and caulking well will minimize vibration noise.
Final Thoughts
The key to successfully installing cabinets on metal stud walls is having the right combination of specialty fasteners, adequate structural supports, and proper planning.
While the prep work is more intensive than a basic wood stud install, the end result can be even stronger and longer lasting if done correctly. Just take it slow, reinforce every connection point, and do not skip steps.
With the right techniques, you can take advantage of metal studs like commercial builders and gain durable, professional quality results. Just focus on fully supporting the cabinet weight across multiple studs and anchoring every attachment point securely.
