Product description The Lindab LDI steel / LDP / LDC steel sectional doors are suitable for nearly all building types in terms of operation, design and installation. Thanks to the various combinations of panel, design and hardware, this door solution can be installed in almost any type of building. When activated, the door leaf slides up under the roof for optimal use of the existing room height, leaving the door opening with full clear- ance. The overhead sectional door has three main parts: 1) Door leaf. 2) Hard- ware set. 3) Electrical operating system or pull chain. The door leaf is made of roll formed steel or aluminium with a 46 mm polystyrene core. The door leaf features finger protection, a rather unique thermal bridge separation in the panel centre, and top and bottom EPDM seals. In addition, the panel is equipped with slotted end cassettes for improved insulation. The hardware set including the counter balance system is made of galvanised steel as standard. The balancing system comprises a shaft fitted with torsion springs, cable drums and cable harnesses, ensuring the correct weight balance when the door is operated. The standard op- erating system comes with energy saving features such as ½ opening height and auto-close programming which reduces energy costs. The software can be up- dated for future improvements and new features, ensuring long-term operation.
