Garage doors are an essential component in building construction. That is why there are many different garage door models on the market. However, sectional garage doors are one of the most sophisticated and practical solutions and can be used for prefabricated garages, single garages, double garages or underground garages. Sectional garage doors offer significant advantages over conventional flip-up doors, such as the lack of a swivel range when opening and closing. This means, for example, that the space in front of the garage can be fully used to park a second car. In addition, a garage located close to the sidewalk or street does not affect the flow of traffic and passers-by. An important advantage of our modern garage doors is the maximum space saving in the garage itself, since the width and height of the passage can be almost fully utilized, so owners of wider and taller cars particularly benefit from having a garage door made by Grandsea installed.
