However, the demand for larger sized doors is constantly increasing from customers such as shipyards, power plants, small airports and the agricultural sector.
There are three main challenges for larger sized doors:
Wind load resistance; their weight; and the counterbalance system to make the doors work. In many instances larger sized doors are installed in exposed locations such as on the coast or in other open spaces where the winds blow with greater force.
Increasing the size of the door increases the combined weight of the panels. For example a 15m X 6 m door can weigh up to 1000kgs and as a result, a powerful counterbalance system and motor is necessary to handle such a huge machine.
Newly designed lightweight sections, aluminum reinforcement profiles and powerful operators allow much wider and higher doors to be manufactured. Ryterna’s engineers have developed several different counterbalance systems capable of operating these larger sized doors and at the present time it is possible to produce doors up to 15 metres wide and up to 15 metres in height.
The main advantages of Ryterna’s larger sized sectional doors are long service life; low maintenance costs; high thermal resistance; the ability to withstand the effects of the environment; competitive pricing; and short production lead times.
All Ryterna larger sized sectional doors are bespoke, so they are made to the individual customer’s order. Installation services are available if required.
