The Hidden Costs of Off-the-Shelf Sheet Metal Enclosures

When it’s time to build enclosures, is your team’s go-to process opening a catalog and ordering an off-the-shelf option?

For prototyping, that makes perfect sense. But when volume kicks in, that same decision could be costing you more than you realize.

Nu-Way Industries is a custom sheet metal enclosure fabrication partner that helps OEMs move from high-priced catalog boxes into value-driven custom enclosures. With precision sheet metal forming, electromechanical assembly, and in-house powder coating under one roof, Nu-Way delivers custom sheet metal enclosures that arrive ready to load, eliminating the modifications, wasted material, and hidden costs that come with catalog enclosures at scale.

Catalog Boxes Have Their Place

When you’re instructed to “hurry up and make a prototype,” that’s what you do. And there’s typically no faster or more cost-effective way of doing so than purchasing a few simple off-the-shelf catalog boxes. At this stage, it can be difficult to justify the cost of custom sheet metal box in small quantities. But once the design is finalized and volume ramps up, those off-the-shelf options suddenly get expensive. Even with a volume discount, those catalog sheet metal enclosures are often far more expensive than a custom-fabricated solution.

It’s not just the cost of the box itself that drives expense, but also the time required to get it ready for use. Before catalog enclosures can be loaded, someone must spend time drilling holes, adding lances, installing studs, and making whatever other adjustments are needed to prepare it for assembly. That labor adds up, but because it’s happening on the production floor rather than in the purchasing process, it’s easy to overlook.

Unless buyers are given this context and visibility into potential savings, they’ll often continue sourcing what they always have. That’s why production teams must communicate what’s actually involved: “We do a lot of work to this catalog box before we can even load it.” When buyers understand the full picture, they can start asking the right questions and exploring sheet metal fabrication services that eliminate that hidden labor.

The True Cost of “Close Enough”

When selecting sheet metal enclosures from a catalog, you’re limited to what’s available. One option is too short, another is too shallow, and you end up with an oversized enclosure simply because it’s the closest available fit. Add to that all the labor involved in modifying each box before it’s ready for assembly, and the true cost of “close enough” comes into focus.

Wasted Material

A larger box means more material, and more material means higher per-unit costs. A custom fabricator looks at what’s actually going inside the enclosure and right-sizes it accordingly. In some cases, that means questioning design choices that were only made because of catalog limitations. Does the enclosure really need a double door, or would a single door with one hinge and one lock do the job for less?

Wasted Space

Oversized enclosures take up more room on the production floor, in storage, and at the final installation site. In industries where space is already at a premium, that footprint matters.

Shipping and Logistics

Larger boxes mean fewer units per pallet, which means more pallets, more shipments, and higher transportation costs. Reducing the enclosure size to fit actual needs creates a domino effect that goes well beyond the unit price.

Backplanes and Internal Components

Many catalog enclosures can be ordered with or without backplanes, but those backplanes typically arrive as blank pieces of sheet metal with no features. OEMs are then left to remove and modify them to accommodate mounting points, wiring, and internal components.

With custom fabrication, those features are built into the sheet metal backplane from the start, ensuring proper fit and alignment.

Door Modifications

Doors on catalog enclosures often require additional customization. Cutouts for windows, switches, indicator lights, or HMI panels are rarely included, forcing teams to modify doors after purchase.

A custom fabricator can incorporate these features directly into the door design, improving consistency and ensuring everything is positioned exactly where it needs to be.

What Custom Fabrication Delivers

When you work with a custom fabricator, the enclosure arrives ready to load. Every hole, lance, stud, and fastener is already in place, eliminating the modification work that eats up time on your production floor.

But the benefits go beyond labor savings. A custom fabricator asks questions that a catalog never will: What’s your end use? Do you really need all this space? Would a single door work instead of a double? These conversations lead to right-sized enclosures that reduce material costs and simplify the final product.

Working with a partner like Nu-Way Industries means accessing multiple capabilities under one roof:

• – Precision sheet metal fabrication services
• – In-house powder coating, including custom colors to match your brand
• – Electromechanical assembly and integration

That means fewer vendor handoffs, faster turnaround, and a finished sheet metal enclosure that’s ready to go the moment it arrives. When you hit that tipping point where modifying off-the-shelf units just isn’t worth it anymore, Nu-Way is ready to help. We’ll look at what’s going in the box, ask the right questions, and build a solution that fits.
