The firm grando was founded in 1924 by Hubert Granderath as a joinery business. In 1954 his son Robert Granderath took over the firm and, in 1963, developed the first fully-automatic rigid-slatted swimming pool cover. With this innovation,  the foundations were laid for an expanding and successful company. Since then, grando has grown to become one of the world's leading manufacturers of pool covers.

Today, grando guarantees swimming pool owners in more than 54 countries around the world unlimited swimming pool enjoyment – made in Germany.

Despite its international activities, grando has remained a transparent, clearly structured enterprise. Flexible enough to respond quickly to new demands and personal enough to offer customers exactly what they expect: new ideas, reliable service and individual advice.
