The main things to consider when planning doors for fabric structures:
• The first thing to consider when picking the type of doors for fabric structures is the size of the opening you need with ample clearance on either side for the equipment that will enter the building. Make sure you allow for any loads that may be carried and the likelihood that your equipment may be upgraded to a larger size in the future.
• The height you need. Consider increasing the height if using cranes to bring items into the structure or the height of tipping trucks.
• The number of times you are going to use the door. Do you need a fast operation to control air pollution or will it remain open for the day.
• Do you need the door to seal the structure against pests or gas/dust escape or just for security?
A self supporting hydraulic roller door that doesn’t stress your structure. The door attaches to its own framing and can open and close in 24 – 40 seconds, gliding along a slide column.
The door has an automatic locking mechanism at the top and bottom of the door frame. Externally there is a three cord truss in the centre of the door, supporting the frame from the mid point. The door lifts up and 50% slides back into the building. This reduces the amount of steel in the door compared to full height top hinged doors. They are ideal for aircraft hangars.
The doors for fabric structures which are popular are the bi-fold doors. They have two or more panels, reducing wind exposure, and an overhead track with the leading edge being attached with a heavy duty roller.
There are no tracks on the ground leaving clear access. The benefit of these doors is that they are easy to open one side or both for equipment or personnel access. Mainly used for smaller doors up to 5-10 m wide.
High Speed doors:
High speed doors for fabric structures are an option for high traffic areas where the door must be open and closed many times during the day.
If dust or other environmental contaminants must be enclosed within the building, the high speed doors will normally fulfil your compliance obligations either as a single door or as a dual door system with an air lock.
Depending on your location, doors will normally come with a twelve month service contract to ensure your door meets your expectations.
Single or double doors hinged on one side. With the single door you have a large area of wind exposure which is a safety issue with larger doors.
The big surface are of larger doors can be caught by gusts of wind and be uncontrollable and be a safety hazard.
These doors for fabric structures are mainly used for smaller doors up to 5 m wide. If you have a situation, such as long term storage, where the doors will be opened occasionally these doors could suit you.
Designed so as the end of the shelter can be opened to almost 100%. Made from shade cloth or PVC . They will have a vertical pipe in the end of the fabric which fits on a spigot at the top and a ratchet mechanism on the bottom, which allows the door to be tensioned horizontaly. This is similar to a truck side tarp system.
Height of the door is limited to about 5 metres as it then becomes hard to locate the top spigot easily with the tension pipe. There is a large area exposed to the wind and you have to be careful when opening and closing that a flapping door cannot damage to people or property.
Roman Blind Type:
Roman Blind type doors for fabric structures are suitable for full width hangar doors which are not used on a regular bases. The do take time to lift and secure but they are a cheap option for weekend flyers.
Anchors are required to secure the door along the base. They have “D’s” about 300-500 mm apart on the inside with a rope running from a PVC pipe in the bottom pocket to a pulley mounted on the frame.
They are strong with horizontal belly and bottom webbing two ton ratchet straps to ensure they are supported.
Horizontal lift doors
The horizontal lift fabric doors for fabric structures suit wide entrances with lower levels of traffic movement.
They have vertical door track on either side facing inwards with tensioned cables on rollers between the tracks at regular intervals held in pockets in the fabric. The door can be fitted with either electronic or manual lift mechanisms.
Personnel Access Doors:
Personal access doors for fabric buildings can be made of steel or wood.
Personnel access doors (PA) can be provided as steel doors or as wooden doors. The client can retrofit fit their own PA doors at a later date if required by purchasing a door and frame.
The door fame is installed, supported by the existing wall posts and the fabric is secured to the outside with aluminium battens.
Full height Shade cloth doors or fabric doors:
The full height doors for fabric structures are normally used in sanding or painting areas where the materials are delivered with a yard crane. The doors are split to the apex and can be pulled back to the sides of the building, enabling bulky items to enter.
A high quality shade cloth or PVC material can be used for the cladding, depending on the application. A ladder or scissor lift is need to reach the upper mid securing points to ensure the door is fully tensioned.
They are a low capital cost option for full end profile entry.
Double folding panels:
These are inexpensive doors which can be used as a screen to stop people entering the building, or see what is inside, plus they reduce wind.
They are hinged from the outside with a jockey wheel on the ground supporting the end of the first frame. This first panel which has the second panel hinged to it. The ground needs to be firm and level where the jockey wheel tracks.
These can be 2-2.4m high using standard heavy duty shade cloth as a covering secured with battens.
