Sectional Overhead Doors

The DNA Products Sectional Overhead Doors are ideal for use in factories, warehouses and other industrial applications. When space is restricted or there is no room for a Roller Shutter these vertically opening doors are a great solution to your needs. This type of door also offers extra insulation and soundproofing to any opening. Weather seals ensure that all doors are long lasting when used outdoors.

If you are looking for insulation and durability,

look no further.

Sectional Overhead Doors

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 tongue 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.

This is also pre-drilled.

Door Head Gear

Sectional doors are counterbalanced to ensure the smooth running of doors. Using minimal effort. All counterbalance spring calculations are designed to get the maximum life out of the door springs we manufacture (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.

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 Indupart’s 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 an optional anti lift bracket.
