HK Balkonbau GmbH – Your Partner.

We are a company that started with its craftsmanship through:

solid growth
innovative product development
committed employees
market-oriented applications
years of experience

…and has grown to an industrial company that produces quality products for optimal use for our customers.

1983

The company HK BALKONBAU GmbH originated from the company Stahlbau Kreyenberg that has been operating through the founder Hermann Kreyenberg since 1983 in heavy steel construction. Within the frame of the steel construction work, also balconies were built out of steel.

1990

The development of steel/ reinforced concrete balcony systems led to more possibilities of application and higher demand so that in 1990 the independent company HK BALKONBAU GmbH was founded.

The steel component, which previously had been produced in a time-consuming steel frame, trapezoidal plate and epoxy screed, has been replaced by a prefabricated reinforced concrete slab.

This is manufactured in quality-monitored prefabrication plants and is combined with steel supports which use the high load-bearing strength of the steel.

1992

In 1992, a larger production facility was built as the company premises on Hafenstaße burst at the seams and could no longer cope with two expanding companies- Stahlbau Kreyenberg and HK BALKONBAU GmbH. With the purchase of the new production facility „Am Alten Viehhof“ a more rational serial production was started which enabled us to produce up to 4,500 balconies per year.

The production and also the assembly of such quantities can only be achieved with adequate equipment and well-trained personnel.

A computer-controlled saw/drilling line for steel enables several processing steps of the square tube supports in one operation.

2000

In 2000 the aluminium balcony was added to the product range. In order to offer competitive balconies from the outset, a new production hall of 1,000 m2 was built with an investment of €1 Mio. and equipped with state-of-the-art CNC technology and workstations.

The investment was designed for an annual capacity of 2,000 finished aluminium balconies in one-shift operation.

2019 - New Management.

In 2019, Inga Kreyenberg took over the company from her father. She grew into the company at an early age; her first point of contact was through conversations at the kitchen table, and later she worked in the company as a secretary and in the back office of the site management during her studies. Today, the geography and history teacher is responsible for finance, sales and human resources. The academic career changer can contribute her professional experience and expertise at various levels.

Marco Dobes, a qualified industrial engineer in metal construction technology, is also part of the new management team. His responsibilities include technical consulting, production and project management. As is so often the case in traditional family businesses, the management duo makes important decisions jointly.

In addition, the company's founder, as a shareholder, is still on hand to advise them for a good while.
