Perfect quality

Our products are created using a highly meticulous production process. We pay much attention to preparatory research, product development, quality monitoring and distribution. You can therefore rely completely on the quality of our products – and on our excellent levels of service, both before and after delivery.

Sophisticated materials

TBS SOEST makes products from various materials: cast iron and concrete in combination with cast iron, HDPE (high-density polyethylene, HDPE) and stainless steel. This means you can always count on having the most sophisticated material combination for every product – high quality, long-lasting products that have the best characteristics, for the best price.

Cast iron is strong and reliable

It is suitable for products that have to bear heavy loads. As the production of cast iron Moulds is expensive, it is particularly appropriate for large production volumes. Stainless steel has the reliability of cast iron, but is lighter and easy to assemble.


HDPE is light in weight and easy to process and to maintain. We use it for products with a regularly changing design. As it is resistant to aggressive substances, we also use it extensively with water and water level regulation products. We often use a combination of HDPE and stainless steel: strong, light in weight and easy to process.
