Panel 40 mm

The AMTR T40 is a universal steel sectional door engineered for industrial and commercial buildings where energy efficiency and robust performance are key. Featuring 40 mm thick sandwich panels with a thermal break, the T40 provides improved insulation compared to standard S40 panel designs, reducing heat loss and contributing to lower operational energy costs. Designed for flexibility, safety, and long-term reliability, the T40 is ideal for environments that require durable, well-insulated door systems without the need for finger protection.

Key Features

Advanced Insulated Panel Design:

40 mm thick, double-walled steel panels with integrated thermal break, filled with CFC-free, fire-retardant polyurethane foam for superior thermal performance.

Improved Energy Efficiency:

The thermal break significantly reduces heat transfer between the inner and outer steel skins, resulting in better climate control and potential energy savings in temperature-sensitive environments.

Surface Finish:

Stucco-textured panels with horizontal lining.

  • Interior: Standard in RAL 9002

  • Exterior: Available in 10 standard RAL colours, including RAL 9016, 9006, 9007, 9005, 6007, 5010, 3000, and others.

Customization Options:
  • Vision panels or glazed sections

  • Integrated pass doors

  • Manual or electric operation

  • Multiple lifting configurations

Durability:

Constructed with 0.5 mm galvanized steel sheets on both sides, ensuring resistance to wear, weather, and impact.

Aesthetic flexibility – panel surface finish options:

The T40 panels are available in two distinct surface finishes to match the architectural character of the building:

  • Stucco with horizontal ribs (standard) – A textured, embossed finish with classic horizontal lines that provides a durable, scratch-resistant surface and industrial look.

  • Microline 16 mm (optional) – A sleek and modern linear design with fine 16 mm micro-profiling that enhances visual appeal, especially for contemporary façades.


Guide Systems (Lifting Options)

  • Standard lift

  • High lift

  • Vertical lift

  • Low headroom (rear or front mounted spring system)

  • Inclined tracks and custom configurations available


All track systems are engineered for smooth and quiet operation, with long-life torsion springs and optional corrosion-resistant components.

Applications

The AMTR T40 is ideally suited for a wide range of industrial applications, including:

  • Warehouses and logistics centers

  • Production and assembly halls

  • Agricultural and storage buildings

  • Workshops and service bays

Its improved thermal barrier makes it especially effective in environments where maintaining interior temperatures is critical — from food storage to heated production areas.
