Sectional Doors

Sectional Doors are sometimes referred to as up and over doors and are extremely popular as the door slides up under the roof when in the open position, maximising the space around the door opening.  Strong, secure and thermally very efficient, sectional doors make an ideal door solution for most industrial and commercial buildings. Constructed using multiple panel sections built to withstand heavy usage.  When closed each panel seals for maximum insulation and security. Windows can be installed in single or multiple panels. Available in all sizes with either manual or electric operation and you can choose from a massive collection of plastisol colour coatings, powder coatings and factory finish. Damaged doors can be easily repaired using replacement panels. We can supply, maintain and repair Sectional Doors.

Information

PANELS:

Kingspan 610mm x 40mm thick composite panels manufactured using 0.5mm thick hot dipped zinc coated (to BS EN 10147) steel internal and external facing sheets, each with a class 1 surface spread of flame when tested to BS 476: Part 7:1971. These sheets are bonded together using IPU foam, which has a density of 40ks/m3. The panel itself gives a “U” value 0.51 W/m2 K, meaning that typical 5,000 x 5,000 wide door has a “U” value of 0.9 W/m2 K and has formed tounge and grooved hinged joint, incorporating a neoprene seal running the full length of the panel to give excellent weather resistance. 80mm panel also available has a typical “U” value of 0.24 W/m2 K, meaning that a typical 5,000 x 5,000 wide door has a “U” value of 0.54 W/m2 K. The acoustic value of the door panel has a single weighted sound reduction of [RW] of 25db. Standard stucco finish is embossed primer coated to both faces.

DOOR HEAD GEAR:

Sectional doors are counterbalanced to ensure the smooth running of doors. Using minimal effort. All counterbalance spring calculations carried out are designed to get the maximum life out of the door springs (most typical loading docks are calculated to a minimum of 20,000 cycles). The springs are high tensile helical wound steel. Shot blasted for improved performance. The springs are mounted on a steel shaft supported by bearing brackets incorporating sealed bearing rollers, to ensure free running of the shaft. Also mounted on the spring shaft are the cable drums. These carry the aircraft quality cables, which have 7:1 safety factor. These are looped and swaged using a hydraulic press to ensure the cables do not get detached from the cable drums or the brackets which connect the cables to the bottom of the door panels. Spring break devices and cable breaks are fitted to doors as standard to comply with CE markings. 

PANEL OPTIONS:

Kingspan Plastisol XL200 or polyester coating to the external face an extensive range of colours. Internal RAL 9010. Factory paint finish to either internal or external face to any BS or RAL colour.

PANEL HARDWARE:

The roller carriers are adjustable and along with the intermediate panel hinges, are hot dipped galvanized steel. The rollers which run in the side track are sealed for life, self-lubricating bearings c/w a nylon tyre to give smooth and quiet operation and sealed directly to the seal connected to the side fixing angle. This is also pre drilled. 

GUIDE TRACKS:

The door tracks are galvanized steel ‘J’ type (designed to give free and easy running for bearing rollers). These are mounted on a galvanized steel jamb angle for fixing purposes via a unique stud welding system which ensures the most effective seal to the building as the tracks need no adjustment on site. Cable break devices are fitted to all doors to comply with CE markings, we also offer a optional anti lift bracket.

GUIDE TRACK Options:

Guide tracks are individually manufactured to suit site conditions, taking into consideration door size, headroom and roof pitch.

SEALS:

All sectional doors are fully perimeter sealed, as well as the intermediate panel seals, to provide the most effective weather seal to your door. All fixing faces, floors and lintels must be flush and square.

OTHER OPTIONS:

We offer a range of optional extras, including but not limited to double-glazed windows, integral personnel doors in main door and door safety furniture. 

INSTALLATION:

Normally includes two skilled erectors and site drilling.  An adjacent power supply is required for hand tools.  We do not include any builders work, unloading and placing near opening unless requested.  We assume structure to receive the door to be firmly and suitably constructed.
We are available to undertake regular maintenance and repairs.

MAINTENANCE:

Sectional Doors should be regularly maintained and the maintenance period should be determined according to operating frequency and local conditions to which the door is exposed.  In the absence of information to the contrary, we will assume that site locations are subject to normal climatic and environmental conditions when providing quotations.
