About

About Lang Specialty Trailers Located in Latrobe, Pennsylvania, Lang Specialty Trailers (LST) designs and manufactures premium portable facilities–including restroom, shower, laundry, bunk-house, and combo trailers—specifically for rental operators. Why Lang Specialty Trailers Stands Out: Operator-focused build: The company is run by former trailer-rental professionals, giving them insight into real-world challenges operators face—durability, ease of setup, maintenance, and long-term value. Versatile product lines: LST offers a range of series to match different needs and budgets. For example: Pro Series: high-end features like composite walls/floors, self-leveling stairs, spray-bar clean-out, heavy duty tank surrounds. Eco Series: streamlined, more affordable options with simplified plumbing and fewer bells and whistles—but still built to LST’s standards. Luxury & ADA Series: designed for special-events, upscale environments, or permanent/semi-permanent installations; features include decorative finishes, full-length doors, ramps for accessibility. Wide application span: Our trailers serve many industries—weddings and special events, construction and industrial sites, film production, disaster-relief and non-profit facilities. Ease of maintenance & parts access: Our trailers are designed for rugged rental use, with components that are easy to service and for which parts are broadly available. What to Expect: From first contact, you can expect a business that understands both the rental business model and the equipment side of the industry. Our facility in Latrobe is staffed by manufacturing professionals who integrate operator-feedback into the design and build of each trailer. Why Choose Lang?: If you’re launching or expanding a trailer rental business (restroom, shower, laundry or bunk-house units), Lang Specialty Trailers offers a partner approach: equipment built for the demands of the rental environment, backed by a company whose roots are in that very business.
