Custom parts when catalog hardware won't fit

Sheet-metal brackets

Custom mounting brackets fabricated to a project's specific attachment geometry when a standard catalog bracket doesn't fit the roof, rack or enclosure it needs to mount.

Cable assemblies

Custom-length cable and wire harness assemblies with the connectors and certifications a project's specific routing and equipment require.

Powder coating

Corrosion-resistant coating for steel and aluminum components in coastal or otherwise corrosive site conditions, applied to a project's actual hardware, not a generic finish.

Enclosures & NEMA boxes

Custom electrical enclosures built to the NEMA rating a site's environment demands, sized to the specific equipment going inside them.

Prototyping & short runs

Rapid prototyping and low-volume production runs for a design that needs field validation before committing to a full production order.

Skid-mounted systems

Pre-assembled, containerized equipment skids that arrive ready to set and connect, cutting field assembly time on a tight schedule.

Parts that fit and pass inspection

Get the part that actually fits

Custom fabrication solves the mounting, routing or enclosure problem a catalog part can't, instead of forcing a design change to fit off-the-shelf hardware.

Confirm the required documentation

Specify the drawings, materials, tolerances and documentation your project requires. Confirm certifications and inspection responsibilities with the fabricator.

FAQs

When does a solar project need custom fabrication instead of catalog components?

Custom fabrication makes sense when a catalog part does not fit the site, the geometry, or the load, common with odd bracket angles, non-standard enclosures, specific cable lengths, or skid-mounted assemblies. Rather than forcing a stock part or field-modifying it, a part built to spec fits correctly and keeps the install clean. Sunhub handles brackets, enclosures, cable assemblies, and skids when the catalog runs out.

Can fabricated parts be certified to the same standard as catalog equipment?

Yes. Custom parts can be built and certified to the same applicable standards as catalog equipment, whether that means UL-listed enclosures, code-compliant cable assemblies, or documented material specs. Certification is part of doing it right, not an afterthought. Confirm the specific listing your AHJ or IE requires and it can be built into the fabrication scope.

What's the typical lead time for a custom fabrication run?

Lead time depends on part complexity, material availability, finishing like powder coating, and run size, so a simple bracket turns faster than a skid-mounted assembly. Prototyping and short runs are handled differently from production quantities. Share the drawing or spec and the fabrication team can give you a firm lead time for that specific part.
