What size doors can MAXDoor provide?

We can provide any size door that you may require. MAXDoors are typically available in door widths from 8-ft wide to 80-ft wide. The wider the door the larger the horizontal beam. Horizontal beam size and spacing are determined by the required wind load. We can provide any door height you may need. When sizing a MAXDoor we refer to the Clear Door Opening size.

What Door speed is available?

Standard door speed is 10-12 inches per second. Model SD High Speed doors are available in speeds up to 60-inches per second, depending on door size. Model HD High Speed doors are available in speeds up to 36” per second depending on door size. All Doors including Model HD-XL are available as a custom High-Speed Door.

Can you provide 150-psf wind load?

Yes, all door sizes are available with High Wind Load or High Positive / Negative Pressure Resistance. We can offer high wind load for any size door opening because of the variety of horizontal beam sizes and the ability to change the horizontal beam spacing. We can offer higher wind loads if needed. Wind load is directly affected by the width of the door required and not necessarily the height.

How does the MAXDoor withstand high wind loads?

The dual layer fabric curtain has aluminum horizontal beams spaced at typically 36” centers. These horizontal beams transfer the wind load into the door guides and then into the building steel. MAXDoors are designed for a constant wind load and do not go by a 3 second wind burst typical of the local building codes.

How is the door lifted?

MAXDoors are raised and lowered via lifting belts that wrap around a belt drum in the head member. A gear motor turns the main shaft that is attached to the belt drums. For every lifting belt, there is a redundant lifting belt to back it up. The back-up redundant lifting belts are the same size and capacity of the lifting belts.

What happens if you have a tear in the fabric?

If the curtain is torn and needs to be patched you cover the torn area with PVC curtain material and secure the patch with adhesive or double sided tape.

Can the MAXDoor be cleaned?

  • The curtain can be power washed with a medium pressure washer.
  • Electrical devices should not be washed.

Can the door be made for explosion proof environments?

How does MAXDoor reduce operational and energy costs?

  • MAXDoor reduces operational costs by having a service life of 20-25 years. MAXDoors are designed for hundreds of thousands or millions of cycles with minimum maintenance costs. MAXDoors operate faster than rolling steel, sectional overhead, or other vertical lift doors. This faster operating speed helps minimize heating or cooling costs.
  • MAXDoors reduce energy costs by minimizing air entering the building when closed.   The fabric panel is one piece so there is no place for the wind to penetrate. Unlike a rolling steel door or sectional overhead door that has many joints or areas for the wind to enter. The MAXDoor curtain also overlaps the door guides by 2.5 inches. The weather seal keeps the wind out at the sides of the door. An optional brush and vinyl weather seal is available for extreme weather sealing.

How do Climate Controlled Buildings benefit by using MAXDoor?

MAXDoors reduce operating and energy costs on Climate controlled buildings by operating faster and by minimizing air infiltration when the door is closed. An insulated door panel is also available.

How does MAXDoor save on service calls?

  • MAXDoors require very little maintenance and when accidentally hit, they often pop out of the door guides without any damage to the door.
  • MAXDoor is the only door with this type of capability because of its durable parts and flexible design.

How is MAXDoor built?

MAXDoor is built with dual layer fabric panels that operate like a roman shade allowing the weight and wind load to transfer from the traveling door panel to the door guide at every horizontal beam.

Why is the MAXDoor the perfect replacement for a rolling steel door?

  • Typically fits in the same amount of side room as a rolling steel door.
  • Requires much less maintenance.
  • Costs less to purchase on large door openings.
  • Lasts longer as it is designed for many more cycles than a rolling steel door.
  • Provides a much better weather seal.
  • Opens and closes much faster than rolling steel doors.

How does the MAXDoor improve safety concerns?

  • Safety is everyone’s concern and MAXDoor does more than other door manufacturers to protect the employees, product, and equipment around the door opening.
  • We use multiple lifting belts to protect against dropping.
  • The door guides are free from any lifting belts or mechanical devices so it can break away during impact without damage.
  • We use a parallel shaft motor gearbox with brake.
  • Photo-eyes, reversing edges, sensors, are all available to provide additional protection.
  • Intelligent door control panels monitor the area on both sides of the door opening to control when a door can open or close.
  • Lifting belts stay attached to the bottom beam and swing with the door panel when there is a collision.
