Roller gate construction
There are roller shutters made of aluminum profiles or lamellas, as they are also called. To make the strength stronger, the lamellae can be made of extruded aluminum or galvanized steel. Inside each such lamella there are 2-3 bridges, which give the profile excellent anti-burglar properties. To impart heat-insulating properties and additional strength to the roller gates, their slats can be filled with polyurethane foam filler.
Advantages and disadvantages of roller shutters
The mechanism of operation of the rolling gates is the winding of the lamellas that move along the guides to the shaft above the gates. With this opening, there is free passage to the site or entry to the garage. Rolling gates save a lot of space both in front of the gates and inside the garage, which is sometimes very important for a dense building site.
