How to Make Metal Cabinets

Making metal cabinets can seem daunting, but with the right tools and techniques, anyone can build beautiful and functional metal cabinets for their home. In this comprehensive guide, we will walk you through the entire process from start to finish.

Selecting Materials

The first step is choosing the right metal for your cabinets. Here are some of the most common options:

• Steel – An affordable and strong option perfect for utility cabinets. Gauge ratings typically range from 20 (thinnest) to 14 (thickest). Go with a thicker gauge for durability.
• Stainless steel – More expensive but offers a modern, sleek look. Often used for kitchens and bathrooms. Opt for 304 or 316 grade for the best corrosion resistance.
• Aluminum – Lightweight and resistant to rust. Easy to work with and available in various finishes. Drawbacks are lower strength and easier denting.
• Galvanized steel – Steel coated with zinc for extra corrosion resistance. Ideal for outdoor use.

Once you’ve chosen your metal, make sure to purchase the accompanying hardware and supplies: hinges, handles, screws, rivets, clamps, etc.

Design and Measurements

Before building, you’ll need to decide on the size and design of your metal cabinets. Take measurements of the space where they will be installed. Sketch plans indicating interior shelf spacing, drawers, and other details.

Optimize storage space by including adjustable shelves, specialized racks, and custom dimensions tailored to what you intend to store inside the cabinets. Carefully measure and cut all pieces to size.

Cutting and Drilling

Use a circular saw with a metal cutting blade to cut your steel or aluminum to size. Make straight cuts using a guide. For stainless steel, a plasma cutter is preferred for smoother edges.

Drill holes where you will attach hinges, handles, and shelves. Clamp pieces securely before drilling to prevent shifting. Use a center punch on the drilling spot to keep the bit from wandering. Lubricate drill bits to limit overheating.

Assembly and Welding

There are a few options for assembling your metal cabinet boxes. Riveting or screwing together is quick and simple. For the strongest bond, welding is ideal.

Position pieces correctly before welding permanent joints. Tack weld first to double check alignment. Use an appropriate welding method for your metal thickness and type. Practicing first on scrap material can help perfect your technique.

Adding Doors, Drawers, and Shelves

Attach any doors and drawers to your cabinet boxes using the proper hinges. Install drawer slides if adding drawers.

Insert shelving at your pre-measured spots, securing with shelf pins or clips. Ensure shelves are level and sturdy enough for intended use.

Add handles and pulls to drawers and doors for easy access. Includelocks where needed for safety or security.

Finishing Touches

Once constructed, finish your cabinets with these final steps:

• Sand to smooth sharp edges and improve paint/finish adhesion
• Clean metal properly before finishing
• Apply primer then topcoat with spray paint or powder coating
• Add leveling feet for uneven floors
• Seal any raw metal edges with paint to prevent corrosion
• Install with proper anchors for weight and wall type

With precision craftsmanship and attention to detail, you can build custom metal cabinets of exceptional quality to beautifully organize and store for years to come.

Frequently Asked Questions About Making Metal Cabinets

How do I make metal cabinets strong and durable?

• Use thick sheet metal with a low gauge rating
• Weld joints instead of screwing or riveting
• Apply rust-resistant primer and paint or powder coat
• Install sturdy adjustable shelving that can handle weight
• Choose high-quality hardware made for metal

What tools do I need to work with metal?

• Protective gear like gloves and eye protection
• Circular saw with metal cutting blades
• Drill with metal drill bits
• Welder (MIG, TIG, Arc, etc)
• Grinder to smooth cut edges
• Sandpaper to prep for finishing

How much does it cost to build metal cabinets?

• The material cost depends on the type of metal used. Steel is the most affordable while stainless is premium.
• Factors like custom sizes, amount of welding, and finishing choices also add cost.
• For basic steel cabinets, materials may run $50 – $150. More elaborate cabinets could cost up to $500.

What thickness of steel should I use?

• Light duty options like a jewelry cabinet could use 22 gauge steel.
• For standard kitchen cabinets, 20 gauge offers durability without excessive weight.
• Thicker 16 or 18 gauge steel adds strength for heavy items, at the expense of weight.

How do I cut steel sheets for cabinets?

Use a circular saw with a metal cutting blade, lubricating the blade to limit friction and overheating. Make straight cuts by securing a guide. A plasma cutter also works for stainless steel. Angle grinder for small cuts.

What are some cabinet design tips?

• Maximize storage with interior racks, adjustable shelving, and custom inserted drawers
• Include ventilation holes if containing electronics
• Use quality hinges, slides, and handles to ensure smooth operation
• Add lockable cabinets for chemicals, tools, or other dangerous items
• Match handles and finishes for a cohesive look

How do I attach hinges to metal cabinets?

• Use hinges made specifically for metal, like self-closing or five-knuckle hinges
• Position hinge placements precisely on the cabinet door and box
• Drill pilot holes then fasten hinges with machine screws or welds
• Test door swing and alignment before permanent attachment

Building your own metal cabinets allows full customization for your unique storage needs while also saving money. With the right preparations and techniques, DIY metal cabinets can be a fulfilling, budget-friendly project for your home.

Conclusion

Constructing custom metal cabinets may seem like an advanced skill, but with the fundamentals covered in this guide, anyone can achieve professional-level results. Careful planning, precision cuts, sturdy welding, and proper finishing are the keys to success. The end reward is beautiful hand-crafted storage that will last for years or decades. Whether for the garage, kitchen, or other uses, quality metal cabinets built yourself add personalized function exactly where you need it in your home.
