TECHNICAL PROPERTIES
Main Body
Doors are made of two fabrics folding in opposite directions. Fabric sections are fastened to horizontal beams (extruded aluminum T 6063-T6 series). Minimum door thickness is 380 mm that is our special properties. Intermediate beams are retractable by means of an electric motor. The beams have tires for easy operations in windy conditions. The intermediate beams when retracted don’t impede the clear opening dimensions
Bottom Beam
Bottom beam is designed according to wind resistance, dimension of the doors and, load of the intermediate steel beams during door operations. Bottom beam also supply full closing and sealing in heavy wind conditions.
Side guides
Shipyarddoor Flexible Giant® The vertical guides shall be an integral part of the door, made of extruded aluminum with a suitable depth and width dependent on the size of the intermediate beams. The guides shall be designed to provide weather-sealing on the inside and the outside faces. The guides shall be designed to provide sufficient strength to transfer the wind load and safety arrestor forces from the door beams, at maximum wind load, to the jamb steel support system. The guides shall be easily replaceable in case of damage. The installer shall furnish jamb structural steel fasteners of size and type required for attachment of the guide rails as shown on the approved shop drawings.
Cable System
Shipyarddoors are operated with steel cable, maximum of two cable each door that running inside of the door guides. Similarly, the quantity of sheaves used to guide the belts/cables shall be minimized to reduce maintenances’ requirements and spare parts inventories. Belts/cables shall be installed free of any kinks and the system design and sheave diameter shall be such to prevent the occurrence of any kinks or abnormal stress in the operating belts/cables. Where belts/cables pass through openings in the building structure the openings shall be constructed so as to prevent abrasion, wear, or damage to the belts/cables. Sheave units shall be installed in accessible locations which allow inspection and preventive maintenance. Sheaves shall not be located in enclosed locations which are not readily accessible for visual inspection.
Fabric
Specially chosen fabric is suitable for long life. It has very high resistance against to UV damage. We choose especially extreme strong fabric. We also have Arctic Fabric for extreme climatic conditions-secure and sound resistance fabric is available as a options.

Fire Resistance
Fire resistance of the fabric is suitable for any fire safety regulations. Relative Standard is DIN 4102-B1. These materials are difficult to ignite. They include materials such as wood treated with a fire retardant and rigid foam plastics. A fire must extinguish itself when the source of the fire is removed.
Sealing
The bottom beam is furnished with cellular rubber seal(U-Shaped). The side guides on frame structures or mullions have either cellular rubber seals or integral brush seals depending on door type. Specially chosen rubber has high resistance against to outdoor conditions extreme cold and hot weather.
Insulation Data
Standard Shipyarddoor Flexible Giant Fold-Up Hangar Doors have excellent insulations because of its extreme width and sealing properties. Thermal insulations’ value U<0.9 W/m².K Isolated fabric are also available Sound attenuation 12 dB A.
Wind Resistance
Shipyarddoor ® Hangar Doors are designed as a unitary system to withstand wind load specified. Fiber stresses due to combined dead load and wind load will not exceed factors for the material being used and type of loading sustained, operationally 140 km/h also at closed positions can be stand up to 180 km/h. Special conditions can be manufactured up to 230 km/h hurricane standard.
Structural Loading
Shipyarddoor® Hangar Doors are designed withstand dead load, seismic forces and design loads due to pressure and suction of wind calculated in accordance to environmental and building ambient.
Driving Unit and limit switches
The lifting motors are normally located above the door opening. All Shipyarddoor hangar door systems are equipped double motor to supply balanced rising also even 1 motor damaged other can be operated the system. The limit switches are also located above the door opening. Shipyarddoor switch system no way to miss or damage all switch have both of side with safety switch. The door stops on the limit switch when the door is completely opened or completely closed. Should the doors by-pass these limit switches there are also safety limit switches for both directions. In direction upwards the limit switches are located above the door at each end of the door and the topmost moving horizontal door beam will activate them. In direction downwards the limit switches are located above the door opening on the slack strap/rope switches.
Speed
Hangar Doors is operated as a standard 20 cm /s opening and closing speed also it is can be increased up to 40 cm/s.
Safety
All doors is manufactured CE Standard Applicable Directives 89/106/EC-99/93/E Applicable Standards:- EN 13241-1:2003+A1:2011-EN 12978:2008 and Load Arrestors, wind lock, thermic resistance, buzzer and warning light is served as a standard .
