What MTL Manufacturing & Equipment does

MTL Manufacturing & Equipment (legal entity: Metal Manufacturing Inc.) is a steel welding and fabrication company headquartered in Beloit, Wisconsin, operating from 185,000 square feet of manufacturing space across two facilities. The company fabricates steel components for two primary verticals — data centers and power generation — producing switchgear sub-bases, electrical enclosure assemblies, and UL-certified fuel tanks (including 5,000- and 6,000-gallon variants) holding UL142, ULC S601, and UL2085 certifications. Additional offerings include generator fuel train preparation, IT industry base sections, cooling towers (including for cryptocurrency mining applications), roof structures, and custom OEM fabrication services.

Production is supported by capital-intensive equipment including 10,000W Mazak and Bystronic fiber lasers (up to 7'x14' beds), CNC press brakes up to 330-ton 6-axis, 40 MIG welding stations rated to 450 amps, a 22'x70' blast booth with powder paint and bake oven, 80,000+ lb crane capacity over a 50'x350' span, and an in-house trucking fleet for oversized shipments. The company maintains in-house engineering and a Job Shop inventory/quoting system.

MTL operates a project-based B2B sales model with custom quote pricing ("Request a Quote" funnel), targeting enterprise customers in data center, power generation, automotive, IT, and crypto mining segments. On March 2, 2026, Power Solutions International (NASDAQ: PSIX) acquired 100% of MTL's outstanding stock to vertically integrate its fabrication capabilities into PSI's data center power systems supply chain, with MTL's management retained post-close.
