Supplies and installs storage and covering systems for all kinds of liquids and solid substances around the world. The storage systems consist of tanks with covers made from prefabricated steel plates or precast concrete elements. The steel plates are supplied with a protective coating such as galvanising, enamel or epoxy coating, but also stainless steel. Covers are made from the same materials as the tanks or alternatively a PVC tensioned cover can be applied. The tanks and systems are designed and engineered in compliance with international standards. This takes into account the local climatic conditions such as temperature, wind and snow loads as well as earthquake zones. The tanks and covers are transported to the construction site in kit form and erected on site by a jacking system or by crane.
