ABOUT

Founded in 1942, Guntert & Zimmerman (G&Z) has been designing and manufacturing specialized heavy construction machinery for the contracting industry since 1947. For decades, G&Z has earned a reputation for pioneering innovative equipment solutions that significantly increase contractor productivity while improving the quality of the finished product.

From the beginning, G&Z has been known for its distinctive innovations and pioneering spirit. The company continuously develops and refines new technologies to meet the evolving needs of its customers. G&Z’s mission is to design equipment that combines exceptional performance, ease of maintenance, and long service life, giving contractors years of productive and profitable use — and the ability to deliver the highest quality end product at the lowest possible cost. Close partnerships with end users and ongoing collaboration in the field are evident in every G&Z design. Whether your machine is brand new or has logged more than 10,000 hours, G&Z stands behind its equipment with guaranteed satisfaction and unmatched support.

Guntert & Zimmerman offers a full range of dependable concrete slipform paving equipment for the construction of roads, highways, and airfield pavements, making G&Z one of the most trusted and respected names in the industry. In addition, G&Z manufactures high-quality Eagle Wheel Trenchers, an excellent choice for high-production trenching applications such as foundations, utilities, oil & gas pipelines, irrigation, and fiber optic installations. G&Z is also the global leader in the design and manufacture of specialized canal trimming and lining equipment solutions for building canals ranging from small irrigation ditches to the world’s largest power channels.

We take great pride in the quality of our products and the expertise of our highly skilled, customer-focused engineering, manufacturing, service, and sales teams.  While the paving industry needs continue to evolve, one thing remains unchanged: G&Z’s commitment to providing equipment solutions that meet these needs and being a reliable partner that meets — and exceeds — customer expectations.
