At Zeman Manufacturing, we supply rugged, high-strength tubing for the heavy-equipment industry, where loaders, dozers, and mining rigs face extreme loads, vibration, and punishing terrain. From chassis rails to hydraulic lines, our tubes are engineered to resist fatigue and corrosion while meeting tight dimensional tolerances that speed assembly and boost machine reliability.
We custom-bend and laser-cut carbon steel, stainless steel, and other heavy-duty alloys, delivering uniform wall thickness, clean weld prep, and repeatable geometry for prototypes through full-volume production.
Structural Frames & Chassis Rails
Heavy-wall tubing forms loader arms, boom sections, and main frames, combining precise bends with high-strength materials for long service life under cyclical stress.
Roll Cages & Protective Guarding
Tubular ROPS cages, bumpers, and guard rails shield operators and critical components, with smooth joints and corrosion-resistant finishes that hold up in harsh environments.
Hydraulic & Fuel Line Tubes
Tight-tolerance tubes carry high-pressure fluids through steering, suspension, and lift systems, cut and formed for leak-free connections and compact routing.
Grab Handles, Ramps & Support Tubes
Ergonomic handles, step ramps, and stabilizer bars improve operator access and machine stability, fabricated for consistent fit and impact resistance.
Trailer & Suspension Components
Precision-formed side rails, seat frames, and suspension tubes integrate seamlessly into trailers and mobile work platforms, balancing strength with weight savings.
