ISD01 industrial sectional doors are engineered for industrial buildings, warehouses, production workshops, transport terminals and other industrial facilities that require higher performance than standard garage sectional doors. These sectional doors combine durable construction with reliable operation to meet the stricter operational and thermal demands of industrial use.

Thermal Efficiency

The door features a continuous sealing system that improves thermal efficiency and helps maintain required internal temperatures in climate-controlled and production environments. Insulated panels reduce heat transfer and contribute to energy savings. Sealing around the perimeter and between panels limits air infiltration and prevents dust and moisture ingress.

Operation and Automation

The door leaf is counterbalanced with a torsion spring mechanism to ensure smooth, balanced movement and reduce strain on the drive unit. This balanced design supports frequent cycles typical for logistics and transport terminals. The ISD01 is compatible with a range of drive units and automation systems, allowing integration with remote control, access management and safety interlocks.

Construction and Durability

Construction uses heavy-duty panels and reinforced guides to withstand industrial wear. Hardware components are selected for durability and corrosion resistance. Design prioritizes easy maintenance and fast replacement of wear parts to minimize downtime. Optional features include vision panels for natural light, pedestrian pass doors, and additional insulation or anti-condensation solutions.

Applications

Typical applications include warehouse loading bays, production halls, service areas and logistics terminals where thermal performance, operational reliability and safety are essential. For exact technical specifications, available sizes, insulation values and conformity certificates contact DoorHan or your local DoorHan dealer.

Door leaf weight, kg/m²	13,5	depends on type and size of door panels

Door leaf should smoothly slide vertically along the tracks, and be properly balanced, i. e. counterbalancing mechanism should compensate leaf weight.

For opening the door in manual operation use only the door handle.

Do not lift too much force when opening/closing the door. Prevent any sharp movements of the door.

Keep people and animals clear of opening while door is operated.

Never stay within or cross an opening with a moving door leaf as it may cause serious injury or death.

Don’t strike the door leaf or obstruct its movement.

Keep the door opening clear of any objects and litter as it may unbalance and jam the door leaf.

Keep tracks and rollers clean, as dirt may prevent the door from smooth movement and cause overloading and damage of the door operator (if used).

Additional Information print

Sandwich panels should be stored in producer’s packaging on a flat horizontal surface in warehouses or under a canopy for a period not exceeding 6 months from the production date. Provide proper protection from water, snow, dirt, and direct sunlight.

Warranty print

DoorHan warrants to the original purchaser of the product that the sandwich panels and steel profiles of the track system will be free from corrosion for a period of ten years.

New Products

Lightweight cylindrical shaft for outside mount on a 60 × 40 mm tube is an affordable device for sectional doors of up to 4 750 × 3 500 mm.

Lightweight brackets system make installation of outside cylindrical shaft (bottom mount, 100 × 100 mm tube) easier, whilst being very strong and durable. Vertical angles used to mount this system made it possible to reduce the requirements for side room clearance. As there is no need to use additional fixtures when preparing the opening the weight of the system was reduced and installation time minimised.

Special support bracket enables installation of any DoorHan shaft opener on a shaft below outside mounting system on a 100 × 100 mm tube.

All drums have special cable holes which make installation easier and provide proper fixation of the cable.

New rollers have sealed bearings to prevent dust penetration and increase service life.
