How to Install Corrugated Metal Under Kitchen Cabinets

Installing corrugated metal panels under your kitchen cabinets can add an attractive, durable, and easy-to-clean surface to your kitchen. With some simple tools and materials, you can complete this project in a weekend. Here is a step-by-step guide on how to install corrugated metal under kitchen cabinets.

Selecting the Right Metal Panels

When choosing metal panels, opt for galvanized steel or aluminum sheets with a corrugated surface. This ridged texture not only looks great but also provides strength and durability. Consider the following when selecting metal panels:

• Gauge – 26 to 29 gauge panels are ideal for this application. The lower the gauge number, the thicker and more durable the metal.
• Sheet Size – Measure under your cabinets and buy sheets at least 6 inches longer than needed to allow for trimming. Common sizes are 2×2 ft, 2×4 ft, 3×5 ft.
• Style – Ribbed, boxed, or V-shaped corrugations are common. Go with your preferred visual style.
• Finish – Raw metal or powder coated in various colors. Raw has an industrial vibe.
• Material – Galvanized steel is affordable but prone to rust over time. Aluminum is lightweight, won’t rust, but costs more.

Preparing the Area Under Cabinets

Before installing the metal panels, you need to prep the installation area:

• Remove any existing under cabinet materials like shelving, plastic laminate, or tile.
• Clean the bottom of the cabinets and the wall underneath so they are free of dirt and grease.
• Check for level – use shims if the underside of cabinets is not level. This provides a smooth surface for attaching panels.
• Fill any cracks or holes in the wall with spackle and sand smooth.

Cutting the Metal to Size

Measure the width under your cabinets and cut the corrugated sheets to length using tin snips. Leave at least 1 inch extra on each end for now. You’ll trim to exact size later.

Other cutting options:

• Aviation snips – best for cutting curves and notches
• Nibblers – small bites, good control for detailed cuts
• Electric shears – quick cutting but noisy

Wear gloves and safety glasses when cutting metal. Work slowly and carefully.

Installing the Panels

Follow these steps to install the corrugated metal sheets:

Attach Support Ledger Boards

Cut 1×2 inch wood boards to length so they fit between cabinet side walls. Use construction adhesive and screws to attach a ledger board against the wall, a few inches below the cabinet bottom. Install another along the front, below the cabinet face frame.

Add Filler Pieces

If there are gaps of more than 1/4 inch between boards or wall, cut and adhere wood shims or spacers to fill gaps. This provides a flush mounting surface.

Prime and Paint Boards

Sand any rough edges on the ledger boards. Wipe away dust. Apply 1-2 coats of primer and then paint the boards to match your cabinets or wall color.

Cut Panels to Exact Size

Measure between ledger boards and trim metal panels to fit, allowing a 1/8 inch gap on all sides. Double check fit before final cuts.

Drill Mounting Holes

Clamp panels over ledger boards. Drill clearance holes through the metal where it aligns with boards below. Remove panels.

Apply Adhesive to Boards

Run a zig-zag bead of construction adhesive along the top of both ledger boards.

Attach Panels with Screws

Carefully align pre-drilled panels and press into adhesive. Insert screws with washers through holes into boards below. Wipe away any excess adhesive squeeze-out.

Repeat Steps

Follow the same process to mount additional panels, trimming corrugations if needed for a tight fit. Rivet panel seams.

Finishing Touches

Once all panels are installed securely, complete the job with these steps:

• Use silicone sealant around all edges for waterproofing and to prevent rattling.
• Attach trim pieces (optional) where panels meet side walls for a finished look.
• Consider adding LED puck lights to the underside of cabinets to illuminate the metal panels.
• Keep panels clean by wiping down with a soft cloth and mild cleaner. Avoid abrasive scouring pads.

And that’s it! With handsome corrugated metal installed below, you can transform the look and functionality of your kitchen. This metal surface is easy to wipe down while adding visual interest and durability.

Frequently Asked Questions About Installing Corrugated Metal Under Kitchen Cabinets

What kind of metal works best for this?

Galvanized steel and aluminum are most commonly used. Opt for 26-29 gauge sheets for the right balance of durability and easy handling.

What tools do I need?

You’ll need tin snips, drill, screws, construction adhesive, silicone sealant, safety glasses and gloves, plus basic tools like a tape measure, level, clamps, etc.

Should I prime and paint the metal panels?

Priming and painting is optional but will provide extra protection from moisture and improve aesthetics. Use a high-quality primer suited for metal.

What’s the best way to cut the metal cleanly?

Aviation snips are ideal but you can also use tin snips, electric shears or a nibbler tool. Take it slow and steady.

How do I ensure the panels are mounted flush?

Using ledger boards provides a level surface. Shim any gaps between wall and boards before installing metal panels.

What type of screws should I use?

Self-tapping metal screws with washers are recommended to prevent sheets from buckling when tightened.

Should I seal the edges of the panels?

Yes, use a silicone sealant around all edges and between panels. This prevents rattling and moisture getting underneath.

Conclusion

Installing corrugated metal under your kitchen cabinets can give this space an instant facelift with an attractive, modern industrial vibe. While it may seem intimidating, this is a DIY-friendly project that you can tackle in a weekend with the right materials and preparation. The end result will not only look great but will also provide a durable and easy-to-clean surface that holds up to heavy use and messes in the kitchen. Just be sure to measure carefully, prime and paint boards, pre-drill metal, and properly seal edges. Get creative with metals in different colors or mixes of textures. With the right know-how, you can take your kitchen up a design notch with metal corrugated panels.
