Aluminum Electrical Enclosure

Aluminum electrical enclosures are our most common configuration for building a NEMA cabinet. Aluminum NEMA enclosures offer a unique mix of strength, low weight, and corrosion resistance.

When these features are combined with aluminum’s low cost, it becomes an obvious option for a wide range of applications.

Aluminum electrical enclosures house PLCs, terminals, drives, and instrumentation wherever weight, corrosion resistance, and heat dissipation matter at the same time — indoor control cabinets, outdoor utility equipment, telecom sites, and marine-adjacent installations. Aluminum offers one of the best strength-to-weight ratios of any enclosure metal, and its thermal conductivity helps enclosed electronics shed heat without extra ventilation.

As a manufacturer, we build aluminum enclosures to order rather than only from a fixed catalog. ElectricalCabinet has built electrical enclosures since 2010, delivering more than 4,000 projects for industrial clients. Our fabrication covers CNC punching, bending, and welding, with custom cutouts, sizes, and surface finishes built to your drawings. Send us your layout and we will confirm material grade, thickness, and finish options for your environment.

Advantages of Aluminum Electrical Enclosures

Aluminum is a commonly chosen material for electrical enclosures. It possesses numerous distinctive characteristics that render it exceptionally suitable for safeguarding electrical equipment. At ElectricalCabinet, we have a deep understanding of the technical aspects involved in electrical components. That's why we prioritize using high-quality aluminum for our enclosures. This choice of material brings a range of benefits to your business:

  • Powerful: Aluminum is known for its durability and ability to withstand impact, mechanical breakage, and fractures. In addition, our robust enclosures are engineered to withstand stress and prevent cracking.
  • Resistant to corrosion: Aluminum exhibits exceptional resistance to corrosion, resulting in a prolonged lifespan for the enclosure. Given the various environmental factors such as saltwater, weather hazards, and UV rays, aluminum proves to be more durable and resistant compared to other metals.
  • Efficient and compact:Aluminum is known for its lightweight nature and impressive strength-to-weight ratio.
  • Efficient at transferring heat: Aluminum boasts exceptional heat dissipation, allowing for precise temperature control. It can transfer heat away from electronic components and effectively deflect sunlight.
  • Designed to withstand high temperatures: Aluminum maintains its properties even in extreme temperatures, enabling it to retain its strength in challenging environments.
  • Electronic safeguard:Aluminum possesses inherent properties that contribute to the optimal functioning of electronic devices. It possesses an impressive conductivity-to-weight ratio and is capable of providing protection against RFI and EMI. It has the ability to reflect radio and radar wavelengths as well.
  • One shape: Aluminum exhibits exceptional resistance to distortion, swelling, and deforming, even in the most challenging environmental conditions.
  • Safe for use: Aluminum is a reliable metal that can be installed in any location due to its odorless, non-magnetic, non-flammable, and chemical-free properties.
  • Fireproof shield: Aluminum has inherent fire-resistant properties that provide a level of protection against open flames and the heat they generate.

Custom Aluminum Enclosures

Aluminum alloys have excellent strength and endurance, making them ideal for electrical enclosures that must function well in severe, high heat, and high wear conditions. Aluminum NEMA enclosures are very lightweight, have excellent corrosion resistance, and dissipate heat efficiently. Choose the following choices and extras for your custom-fabricated aluminum cabinets:

  • A number of treatments are available, including wet and powder coat painting, as well as anodizing.
  • Secure and tamper-resistant hardware is available for your aluminum enclosure.
  • There are several installation/mounting choices, including free-standing, pad mounted, wall mounted, pole mounted, and walk-in.

Frequently Asked Questions

Can I order a single custom aluminum enclosure?

Yes. We accept one-off custom builds as well as volume orders. Share your drawings or a sketch with dimensions, and our engineers will confirm feasibility, material grade, and quotation.

Aluminum or stainless steel — which should I choose?

Aluminum wins on weight, cost, and heat dissipation; stainless steel wins in wash-down, food, and high-corrosion environments. If your site sees salt spray or daily hosing, stainless is usually the safer choice; for general industrial and outdoor use, aluminum is often more economical.

What surface finishes are available for aluminum enclosures?

Brushed and anodized finishes for a natural metal look, or powder coating in standard RAL colors for additional corrosion protection and brand matching. Finish is specified together with material grade at quotation.

How does EMC shielding work with aluminum enclosures?

Aluminum provides inherent shielding for electromagnetic interference when doors, seams, and cable entries are properly bonded. For sensitive electronics we review seam design and gland placement with you during engineering.
