The LECHNER GROUP's story is one of highs and lows, determination and female power, hard work and family.

And it starts in the middle of the German Empire, a time shaped by a sense of change, reform and entrepreneurial spirit. The wonder of electrification was making everyday life easier. The expanding railway network and the first cars opened up a whole new level of mobility. And almost everyone was dreaming of a better life. Including in the quiet region of Uehlfeld in Middle Franconia. Georg Heinritz, the great-grandfather of company director Bernd Lechner, established his first construction business here in 1904.

  • 1923

    His son Friedrich Heinritz joins the company in 1923, and the company name is changed to Georg und Friedrich Heinritz OHG.
    Over the next few years, the business expands to include the production of concrete products. Back then, concrete was still mixed by hand (using a shovel). There were no concrete mixers. The main items produced are concrete pipes, slag bricks and coloured cement flagstones pressed with patterns. These cement flagstones are popular as floors in kitchens and hallways. You can still find these floors in old farmhouses in Seebachgrund and Steigerwald today.
    The concrete products are already being supplied further afield to the neighbouring districts of Höchstadt-Erlangen-Scheinfeld.

  • 1935

    As sales of concrete pipes continue to increase, the decision is made in 1935 to make a big investment – and purchase an electric concrete pipe stamping machine, "Triumph 1".
    By 1939, there are 15 employees working at the concrete plant, with the same number of employees in the construction business.
    When the war breaks out, the company shuts down because the company director is called up for military service. Once the war ends and he returns from captivity as a prisoner of war, the company reopens.

    years in

    Georg Heinritz's company worked in construction for almost 20 years, as is evident from the quotation for the construction of a residential building at Steigerwaldstraße Nr. 14 from 1935. This residential building is still standing in its original form today.

  • 1945

    Until the currency reform, the building materials trade and the production of concrete goods is only possible under difficult conditions, in exchange for ration coupons or as a barter transaction.

    After the war, the company founder, Georg Heinritz, dies in 1948 at the age of 71 years.

    One year later, the company director Friedrich Heinritz falls ill and undergoes surgery. He dies as a result of this operation on 20 April 1949 at just 46 years old.
    His wife Margarete and daughter Erna, who is 15 at the time, successfully continue the building material business and concrete plant in the face of strong competition.

  • 1954

    The company gains fresh ideas and momentum in 1954 with the new addition of Hans Lechner and his marriage to Erna Heinritz.

    The family overcomes some challenging times with hard work, dedication and teamwork. Mrs Erna Lechner works hard to build up the office and accounting department.

    In 1954, there are five employees.

  • 1957

    In 1957, the number of employees grows to over 40 and the company name is changed to Heinritz & Lechner KG, Betonwerk-Baustoffe.

    The adjacent picture shows that it wasn't all about work. The first company outing was to Karlstadt/Main with a tour of the cement plant, followed by a boat trip from Veitshöchheim to Würzburg, city tour and dinner.

  • 1964

    Construction of a new, fully automated concrete mixing plant as a low silo series plant with belt feeders on the land of the "Pfarrgarten-Derrer" and start of the manufacture of ready-mix concrete.

  • 1981

    By 1981, the number of employees has grown to over 180 as a result of the company's biggest investment to date: The acquisition of the entire company premises of neighbouring company Heinz Graf, with all its halls, buildings, machines and vehicles, through a bankruptcy sale. The company builds large halls – some spanning over 1600 m² – and plants for the manufacture of large prefabricated components and ready-mix concrete in multiple locations.

  • 1982

    Son Bernd Lechner joins the company. After completing his studies at the University of Applied Sciences for Construction in Nuremberg, he successfully qualifies as a civil engineer.

    In October 1982, he joins the company to support and relieve some of the burden on his father.

    Production expands to include prestressed concrete.

    A 10.0 m self-supporting fully assembled ceiling with approval is developed.
    The production of prefabricated ceilings becomes a fully automated operation.

    New jobs are created.
