At Zeman Manufacturing, we supply precision tubing for the transportation sector—where safety, reliability, and passenger experience all depend on performance you can trust. From seating systems to onboard plumbing, our components support the structural and functional integrity of buses, trains, and commercial vehicles.
We work with stainless steel, aluminum, and other durable materials to produce tubing that resists corrosion, meets weight requirements, and stands up to daily use in high-vibration, high-traffic environments.
Seat Frames
We fabricate strong, lightweight seat-frame tubing with smooth bends and tight tolerances to meet ergonomic and structural standards. Our components support welded or modular assemblies, delivering consistent performance across production volumes.
Grab Bars & Handles
Precision-formed tubing for passenger grab bars and handles combines strength, comfort, and clean finishes. Dimensional control ensures safe, secure handholds in high-touch areas.
Handrails
Custom-bent handrails provide dependable support on steps, ramps, and vestibules. We deliver polished surfaces and accurate geometry for easy installation and long-term durability.
Support Tubes
Structural support tubes reinforce seat assemblies, luggage racks, and interior partitions. Controlled wall thickness and precise end forming keep weight down while maintaining strength.
Air & Water Line Tubes
From brake air lines to climate-control and water-service lines, our tubing handles fluid transfer in demanding transit environments. Tight-radius bending and custom end forming enable efficient installation and leak-free operation.
Public and commercial transport systems rely on components that can perform consistently over years of use and miles of vibration. At Zeman, we build that reliability into every part. With in-house tooling, ISO-certified quality, and a deep understanding of complex fabrication challenges, we help transportation OEMs and suppliers develop tubing solutions that are safe, efficient, and built to last.
