Alfons Greten Betonwerk GmbH & Co. KG
GRETEN MEANS RELIABILITY - OVER 50 YEARS OF RELIABLE SERVICE. Greten has been a partner in the agricultural market for over 50 years. In 1954, Alfons Greten Sr. founded the company, which then flourished into a renowned medium-size business with the help of his wife Anna Greten. At first, Greten only manufactured concrete windows. However, it did not take long for slat panels for pigs and cattle to be added to the range of products. Today, Greten is one of the leading producers of concrete slat panels, without which efficient livestock management would not be possible. Greten now increasingly exports its concrete products to EU member states and other European regions. Greten markets its plastic products, such as hollow chamber slabs, profiled boards, partition walls, barriers, and wall systems for stables and storage depots, in the entire world.
Greten has been producing concrete goods, precast concrete units, and plastic profiles for the agricultural market for over 50 years.
Take advantage of our experience and competence in your construction project. On these pages, we have compiled information about our entire range of products.
Greten markets its plastic products, such as hollow chamber slabs, profiled boards, partition walls, barriers, and wall systems for stables and storage depots, in the entire world. In 1994, Alfons Greten Sr. died. The company has since been in the hands of Anna Greten and Alfons Greten Jr. as well as his wife Anette. Agricultural customers can rely on the company. Greten develops concepts for stable construction and the company's management personally vouches for the quality of the products. Fluctuation is low amongst the approximately 150 employees, which allows valuable experience to be retained.
FLEXIBILITY DUE TO IN-HOUSE PLANT ENGINEERING
Growing customer demands and increasingly changing national and international regulations for livestock management require the utmost flexibility. Factory-owned plant engineering and mold construction allow us to put new products on the market on short notice. The steel reinforcements required according to statical calculations are manufactured on-site with the help of state-of-the art machinery. Computer-based machines for wire leveling, cutting, and welding give Greten flexibility in cases when customers modify their requests.
CONCRETE - IT'S ALL ABOUT HOW IT'S MADE!
The slat panels are manufactured in high-performance production facilities. High-frequency vibrating tables compact the concrete at just the right level. Competent employees produce the desired tread area on the slat panels by abrading and grinding. In modern pallet rotation systems, the freshly stripped products 'rest' for 48 hours, and the components are then put together into packets. The packets are then placed in spray-irrigation systems for a finishing treatment, in which they are kept moist for three days. Factory-owned vehicles or select shipping companies then transport the concrete components directly to the customer's construction site.
Only products which are livestock-friendly and species-appropriate ensure agricultural success. The better the animals feel in their stables, the higher their productive efficiency will be. Farmers calculate with optimal stable equipment at economical prices. Greten uses state-of-the-art machinery and facilities in order to guarantee cost-effective manufacturing. Well-trained long-term employees ensure that the slat panels remain a consistently good quality.
The slat panels are manufactured according to strict production criteria. The concrete quality of all slat panels is at least C 35/45. The factory-owned test centers for reinforcements and concretes constantly check the quality and perform further developments. In addition, Greten is being monitored by the following institutions: Güteschutz Beton- und Fertigteile Nord e.V. (quality assurance of concrete and precast components), Baustoffüberwachungs- und Zertifizierungsverband Nord e.V. (materials monitoring and certification), and Materialprüfungsamt Nordrheim-Westfalen (materials testing).
MODERN CUSTOMIZED STABLE EQUIPMENT
Greten manufactured the first concrete stable equipment in the 1980s. These pen partition grids formed the basis for the development of a variety of systems. The combination of different materials makes even narrow structures possible. Stable equipment made of plastic is gaining increasing importance as well. Greten began manufacturing plastic multifunctional windows for agricultural purposes in the early 1970s. Over the years, concrete windows were superseded by plastic windows.
When the demand for modern stable equipment grew, Greten developed hollow chamber board profiles made of plastic specifically for the construction of pen partitions. The window PVC makes them durable, while the smooth profile surfaces are easy to clean with only small amounts of water, which is beneficial for the hygiene of the system.
STABLE CONSTRUCTION CONCEPTS FOR THE FUTURE
In the year 2000, Greten erected a 50,000 m² high-performance ready-mix concrete plant. Shortly afterwards, a production facility for large-sized precast concrete parts was added. This addition allows Greten to offer its customers a range of trendsetting stable construction concepts and to improve its services.
Farmers bring in completed architect's plans for new stables. Greten builds full prefabricated manure pits. The base layer of the future stable is then segmented according to the plans and with the help of computer-based programs.
Once the plans have been approved, all components can be prefabricated in the concrete plant regardless of the weather. Our personnel then quickly assembles the components on the construction site. First, all exterior walls are set up. The gaskets are already incorporated into the walls. Our mixing vehicles take the ready-mix concrete to the construction site. Then the bottom plate is poured in a conventional manner (without sheeting). After the bottom plate has hardened, the interior walls are put up. The prefabricated components allow for a level of accuracy which cannot be achieved with conventional building techniques. All cut-outs, openings, and connections are already incorporated in the prefabricated parts.
REGIONAL AND INTERNATIONAL PRESENCE AT TRADE FAIRS
Greten is seeking the contact with its customers on many levels. Therefore, the company regularly exhibits at the 'Eurotier' in Hannover/Germany, a trade fair with global impact. At the same time, Greten gets involved at regional fairs and supports builders' merchants in their in-house exhibitions, for example by providing exhibits.
As mentioned before, Greten offers its expertise to various agricultural organizations and fosters contacts in political circles. During a visit at the facility in Essen, Germany, Greten corporate management made Hans-Heinrich Ehlen, the Minister for Agriculture in Lower Saxony, aware of the issues involved in intensive livestock husbandry.
