Company history

After his return from war, Johann Henkenjohann (1922-2010) joins the wood business, representing the third generation. He starts to produce Chippendale furniture feet. A few years later, he produces the first wooden roller shutters. As the quality of wood declines after some time, Johann Henkenjohann decides to manufacture roller shutters from plastic.

New aluminium profiles for doors and windows create an additional production focus.

heroal further expands production capacities with the construction of Plant II in Hövelhof, and puts the first powder coating facility into operation.

The heroal product range is expanded with the development of the first insect screen with a tensioning frame.

heroal starts the production of sliding and lifting-sliding systems.

For the first time, heroal also produces aluminium profiles for curtain walls.

The innovative hwr powder coating is set up in Plant II in Hövelhof. Thanks to the highly weather-resistant (hwr) coating, the surfaces of aluminium systems for windows, doors, curtain walls and lifting-sliding doors are extremely durable.

heroal extends its portfolio with canopy systems for the creation of patio canopies and carports (cold roof).

Dr Vera Schöne, daughter of Gerda and Johann Henkenjohann, joins the company as the fourth generation. During her time as Managing Director, she drives internationalisation and further expands heroal’s product range.

The opening of the heroal logistics centre in Hövelhof, equipped with state-of-the-art technology and fully automatic storage systems with high racks, guarantees heroal customers short response and delivery times during the order process. At the 40,000 m² logistics centre, all heroal products are stored centrally, picked, and delivered to customers with the company’s own fleet of trucks – an important element for the company’s service ethos and growth strategy in Germany and Europe.

heroal opens an additional branch in France (Mommenheim). In the same year, the innovative quality line in Plant II is put into operation.

Dr Vera Schöne withdraws from active business and transfers the management to her son Dr Max Schöne, representing the fifth generation with an involvement in the company.

heroal OR extends the range of canopy systems with a modern system in a timeless design. The patio canopy stands out for its cubic design and numerous accessory options, such as sun protection systems or sliding glass walls.

heroal's service portfolio is expanded to include offers in the areas of training, marketing, calculation, ordering, production planning and optimisation.

2024 is a very special year for the family-owned company heroal, as it celebrates its 150th anniversary. The company, which is now managed by the fifth generation of the family, Dr. Max Schöne and Co-Managing Director Dr. Ramon Knollmann, has around 900 employees, is one of the international market leaders for aluminium system solutions and heroal is involved in the construction of sustainable, high-quality residential and commercial buildings worldwide.
