Technical characteristics of the sectional overhead doors

Overhead sectional doors are produced following the international standards EN13241-1:2003 and certified in SP Technical Research Institute of Sweden. Doors are made of triple-layer sandwich panels. Gap between two galvanized steel sheets filled with freon free polyurethane foam, what gives very well thermal insulation. Total panel thickness is 40 mm. Sectional doors characterized by safety, durability, aesthetic and optimum heat insulation.

Safe construction

Sectional doors components suitable for long-term operation, even in heavy use. Steel profiles, which is coated with hot-galvanizing method, and which is installed inside of the building, providing safety of the construction. Stable hinges provide accurate and reliable connection of the door panels. Ball bearing rollers are strong and quietly, they move in the hardware profiles. Efficient operation of compensating spring shaft allows operating of any size doors. Springs are calculated for 15,000 to 50,000 operating cycles. Springs shock absorbers mounted in a guide at the end, probably absorb the gates opening. For special buildings, available hardware made of stainless steel.

Entrance door

In order to ensure maximum comfort and coordinated transport and pedestrian flow, entrance door can be mounted into the door, having a size of approximately 800 x 2000 mm (width x height). Entrance door comes with a lock, handles, 3 keys and door closer. For better design and safety can be choose ASSA-ABLOY lock and 27.5mm pass door bottom profile, name as a safe step pass door. For automatic doors higher safety level, pass door can be upgraded with magnetic pass door safety switch. It stop door mooving, when pass door is opened.

Windows

Windows is a clear value added to industrial doors. Such gates fits better into the architectural scene and provide optimal space lighting. You can choose double glazed industrial doors:

• rectangular windows 680*373mm, made of acrylic glass double packet;

• panoramic windows made of acrylic glass double packed and aluminum profile panels, which provides maximum lighting.

• stainless steel, round and rectangular windows, made of safety glass double packed, what provides very nice design.

Panel structure and color

40 mm thick "sandwich"-type panel provides excellent thermal insulation and safety. Especially for our thermo panels, exterior steel sheet is separated from the inside sheet, also in the joint places, which allows to avoid freezing. Complete and installed door thermal transmittance U-value = 0.8 W/m2K. For door color, you can choose one of the basic colors, or available painting in any color, according to RAL color catalogue.

 

THERMO PANELS

Thermo panels are produced for Nordic regions, with thermal bridge. For better panel strength added 1mm thick hardening rib. Panel surface are with stucco grain and lines design. Doors made of this panels are with very high thermal transmittance U-value = 0.8 W/m2K (see certification test report.

Door seals

Specially designed sectional door seals perfectly protect from space weather. 1. Top seal. Gate upper panel fitted rubber seal fill the gap between the top panel and the wall. 2. Bottom seal. The bottom panel of the door installed a flexible U-shaped rubber gasket, with additional lamellas, not only protect from frost and wind, but also compensate for small floor unevenness. 3. Intermediate seal. Protect panel of the joints from the cold. 4. Side seal. Double PVC gaskets long retain flexibility even during rapid temperature changes .
