How We Serve

Rail, transit, and fleet aftermarket fabrication

Transportation OEMs and aftermarket programs need a contract manufacturer who delivers consistent quality at production volume: sheet metal brackets that mount the same way every time, equipment enclosures that survive vibration and weather, and chassis components that arrive ready to install. SPM brings AWS D1.3 certified welding, in-house powder coating with weather-durable finishes, and IPC-A-610-trained electro-mechanical assembly to rail, transit, and fleet aftermarket work. For automotive OEM programs requiring IATF 16949 safety-critical certification, we partner-refer. For everything else — rail, transit equipment, fleet aftermarket — we deliver consistent, repeatable manufacturing at scale.

FAQ

Frequently asked

Does SPM hold IATF 16949 for automotive work?

No. SPM is ISO 9001 certified company-wide, but we do not currently hold IATF 16949 and do not manufacture safety-critical automotive components. Our transportation work focuses on rail, transit, and fleet aftermarket — sheet metal components, brackets, equipment enclosures, and chassis for non-DOT-safety-critical applications. For automotive OEM programs requiring IATF 16949, we can refer.

What does SPM build for transportation?

Sheet metal components and brackets for rail and transit equipment, fleet aftermarket fabrications and customization parts, and NEMA-rated equipment enclosures for transportation electrical and control systems. AWS D1.3 certified welding and weather-durable in-house powder coat.

Can SPM produce sheet metal for fleet aftermarket programs?

Yes. SPM serves fleet aftermarket programs with sheet metal components, brackets, and replacement parts manufacturing at production scale. Inventory consolidation through our value-added services helps customers manage seasonal demand swings common in aftermarket programs.

What finishes does SPM offer for transportation equipment?

Weather-durable powder coat with corrosion-resistant primers, custom colors per project specification, and masked-area support. Powder coat is applied in-house, rated for outdoor and harsh-environment transportation installs.
