Retractable, fixed or sliding Steel building systems are generally designed to be applied to cover spaces that need to be stored under cover but at the same time be uncovered for the passage of certain work activities or legal obligations.
One of the most frequent uses in industry is for the storage of material in tanks. The regulations governing the storage of waste impose the need for a roof that protects the stored material from the weather and prevents it from being dispersed both on the ground and in the air.
The use of a retractable canopy fulfils this regulation by allowing small or large areas to be covered and uncovered with speed by means of an installed electric motorisation.
