What is a Sectional Door and What are its Advantages?

Industrial sectional doors are one of the most commonly used enclosure solutions in industrial and logistics environments. Their vertical opening system, which moves upward toward the ceiling, allows for optimal use of available space, both inside and outside, making them a highly efficient and functional option.

These doors are designed to deliver high performance in terms of insulation, safety, and ease of use. At Inkema, we offer versatile models that adapt to the specific needs of each facility and/or loading dock.

How is a sectional door constructed?

Unlike a conventional door, a sectional door is made up of several horizontal panels joined together, which slide vertically along side tracks until they are positioned parallel to the ceiling. This allows the entire opening to be completely cleared.

The main components of an Inkema sectional door are:

• Panels: Made of double lacquered galvanized steel sheet and filled with rigid polyurethane foam injected at high temperature, providing excellent thermal and acoustic insulation.
• Tracks: 2 mm thick galvanized steel profiles that ensure precise and secure sliding. They are available in various configurations depending on the type of lintel: vertical, standard, high, or low.
• Counterbalance system: Equipped with torsion springs designed to guarantee a minimum lifespan of 15,000 opening and closing cycles.
• Fittings and fasteners: Galvanized or zinc-coated, offering high resistance to corrosion and wear.

What are the advantages of a sectional door?

Inkema industrial sectional doors stand out for their versatility, safety, and energy efficiency.

Below are their main advantages:

✔️ Space-saving design
Their vertical opening allows maximum use of the interior space without interfering with transit areas or loading operations.

✔️ High thermal and acoustic insulation
Thanks to their polyurethane-filled panels, they provide excellent insulation, ideal for facilities that require specific thermal conditions.

✔️ Flexibility in sizes and finishes
They are custom-made, from small doors to models up to 8x8 meters. Available in a variety of paint and lacquer finishes to match each company's corporate design.

✔️ Customization options

• Glazed windows to make use of natural light.
• Integrated pedestrian door, with or without bottom frame.
• Automatic motorization compatible with multiple control systems.
• Special 80 mm thick panels for advanced thermal requirements.
• Peepholes, manual handles, external locks, and more.

✔️ Easy maintenance
In case of damage, individual panels can be replaced without needing to change the entire door.

Types of Inkema Sectional Doors

At Inkema, we offer several versions of sectional doors, tailored to different industrial and logistics needs. Each type is designed for a specific use, optimizing both functionality and operational performance.

Standard Sectional Door

The most common option for warehouse enclosures. It offers thermal insulation, durability, and can be easily automated. It is the ideal solution for general use in warehouses, factories, and logistics centers.

Guaranteed Safety and Efficiency

Inkema sectional doors are not only designed to ensure smooth and long-lasting operation, but also to guarantee the safety of people, vehicles, and goods that interact with them daily.

✔️ Integrated safety systems
All our doors can include multiple safety features that comply with current European regulations. The most notable include:

• Cable and spring break safety devices: Prevent the door from falling abruptly in the event of mechanical failure, protecting both personnel and nearby assets.
• Photocells and infrared safety barriers: Detect the presence of people or objects in the door’s path, automatically stopping closure to prevent accidents.
• Automatic reverse system: In motorized doors, if an obstacle is detected during closure, the door reverses its movement to avoid damage.
• Emergency brake: Some models include emergency brakes that activate in case of electrical or mechanical failure.

✔️ High energy efficiency
Another major advantage of Inkema sectional doors is their ability to contribute to energy savings in the facilities where they are installed. This is achieved through:

• Thermally insulated panels: The high-density polyurethane foam core (CFC-free) helps maintain a constant temperature inside the building, reducing heat or cold loss.
• Superior sealing: Precisely designed joints and perimeter seals prevent the entry of air, water, or dust, improving the efficiency of climate control systems.
• Fast and precise operation: Doors can be motorized with rapid opening and closing systems, minimizing the time the door remains open and thus reducing energy losses.
• Optional thicker panels (80 mm): Especially recommended for cold storage rooms or facilities with special thermal requirements.

✔️ Durability and low maintenance
The robust design and high-quality materials used in our sectional doors result in very low maintenance requirements. This means fewer technical stoppages, increased operational time, and a lower total cost of ownership over time.

Thanks to the modular panel system, in the event of accidental damage, only the affected section needs to be replaced, simplifying and reducing repair costs.

Frequently Asked Questions About Sectional Doors

• Do they require maintenance?
  Yes, but it's minimal. It's recommended to periodically inspect the springs, tracks, and hardware.
• Can they be automated?
  Yes, they can be motorized and controlled via remotes, sensors, or automated systems.
• Can they include a pedestrian door?
  Yes, either integrated or independent, to allow passage without opening the entire door.
• Do they provide thermal insulation?
  Yes. Their polyurethane core offers excellent thermal insulation.
• Can they be customized?
  Yes. You can choose colors, finishes, windows, and special panel options.
