A Milestone Honoring 75 Years of Engineering

Kayahan showcased its 75th Anniversary Technical Drawing Project—designed as a hydraulic cylinder–shaped timeline and illustrated using the company’s unique engineering language—during a symbolic signature ceremony held on the second day of the 10th Hydraulic and Pneumatic Congress (HPKON).
The large-scale technical drawing panel visually narrated Kayahan’s production history, engineering expertise, and core corporate values.

The ceremony began with the first signature by Founder Mehmet Kayhan, who laid the foundations of the company in 1950. Following him, Chairwoman of the Board Sevda Kayhan Yılmaz, board members, senior executives, and an employee representing the entire Kayahan team signed specific sections of the drawing, leaving a symbolic mark on Kayahan’s 75-year production journey.

This meaningful moment underscored the company’s three-generation engineering heritage and its unwavering commitment to sustainable production and technical discipline.
The symbolic signatures represented the collective contribution of everyone who has powered Kayahan since 1950, while also reflecting the company’s strong vision for the future.

Held just before the gala and met with strong interest from attendees, the ceremony became one of the most memorable highlights of Kayahan’s 75th anniversary celebrations.
