Know What a Door Lintel Is and The Role It Plays at the Overhead Door Opening

Knowing what a door lintel is and its function can be very useful when the need arises to install a new overhead industrial door on an existing facility. The primary purpose of a door lintel is to provide support for the wall above the door opening. The door lintel is a load-bearing beam that supports the opening in the framing where the door will be installed. The door lintel is a horizontal beam fitted across the top of the door opening to support the bricks or structure materials above the door.  Typically, lintels are made from steel or prestressed concrete. Steel lintels are normally used when the door openings are extensive and are a popular choice due to their strength, durability, and versatility. The lintel material used will depend on the structure of your building. Either side of your lintel must be supported sufficiently to ensure the above load is distributed evenly on both sides.  MAXDoor designs and builds custom under lintel (UL) vertical lift fabric doors up to 65 Feet wide.

MAXDoor Meets the Challenge for Corrosive-Resistant Mine Doors

Indeed, the mining industry can be extremely challenging with factors such as dirt, harsh weather conditions, and the presence of large trucks and land moving equipment.  In such environments, it is important to have durable and reliable doors to quickly close up the outside and inside conditions.  MAXDoor, a vertical fabric lift door, is designed to meet the challenges of corrosive environments.

The Challenge

MAXDoor was presented with a situation requiring the replacement of rolling steel doors at a mine site.  The steel doors were allowing air from toxic environments to leak in and around the doors causing corrosion.  The steel doors were also involved in numerous accidents involving large vehicles entering and existing the entrance to the mine. This resulted in significant down-time, high door repair bills and lower productivity.  The challenge was to design and manufacture vertical lift fabric doors that would alleviate the daily operational problems.

The Solution

To make sure the solution matches the challenge, MAXDoor always takes a personalized approach to the design and manufacture of custom Vertical Lift Fabric (VLF) doors. In this situation, a premium door is needed to handle the daily operations in mining wash bays, crusher buildings, pellet plants, and truck repair shops. MAXDoor offers the following features to ensure your mine and mining equipment is offered full protection from harsh temperatures and high winds:

  • Custom designed door sizes that are built-to-suit for just about any application
  • Minimum load on building structure – Self Supporting
  • High positive and negative wind resistance
  • Excellent environment separation
  • High speed operation
  • No springs or counterweights
  • Designed for heavy industrial environments

The Results

The fabric door is constructed with materials that can withstand harsh conditions and can effectively protect against dust, moisture, and other elements.  MAXDoor’s robust construction and advanced features make it suitable for use in mining facilities where durability and reliability are crucial.

  • MAXDoors simple design has horizontal traveling beams constructed to flex and give way when there is a collision. The mining industry uses large industrial equipment daily and having the right door in place will be beneficial when the door is hit. Real life collisions prove that the horizontal beams flex out of the door guides without damage and are easily put back into the door guides saving hours of downtime and repair costs.
  • Made in the USA, MAXDoor is 2-3 times faster than rolling steel or multiple leaf steel vertical lift doors and will substantially reduce annual operating and maintenance costs.
  • MAXDoors enhance safety and productivity at the mine site.
  • 20-25 Year service life

Go With A MAXDoor Solution For Your Cleanroom

Doors for cleanrooms are a crucial aspect to the design of specially built environments. A cleanroom is a “room within” with an engineered space that maintains a very low concentration of air borne particulates.  These rooms are constructed and operated in a manner to control the introduction, generation, and retention of particles inside the room. These rooms are well controlled for containment and actively cleaned to provide the cleanest area possible.  Securing the right curtain/door in this situation is critical to the overall operation of a cleanroom.

The Best Industrial Doors for Cleanrooms

MAXDoor offers a wide range of reliable curtains and doors for cleanroom spaces.

  • The one-piece curtain minimizes air infiltration when the door is closed.
  • The curtain overlaps the door guide by approximately 2” on each side of the door resulting in dual side seals.
  • The dual layer fabric also minimizes air infiltration.
  • There are no door hinge points to allow air infiltration.
  • There are no sections of joints in the panel – the door is a solid seal.
  • If a cleanroom is under positive pressure, the air pressure creates a tighter seal at the door guides.
  • Alternate fabric choices are available for various types of special environments.

MAXDoor – The Choice for a Composting Facility

The Challenge

A new state-of-the-art composting facility being built in the Midwest required tough industrial doors to be installed on the building to allow the facility to operate year-round in an indoor controlled environment.  A variety of organic materials such as yard clippings, food waste and sludge would be delivered to this high volume composting facility.  The doors for this facility need to be the toughest to meet the climate-controlled conditions inside the facility.  The doors need to be designed for high-cycle operations and must operate at a high speed to accommodate the numerous truck deliveries on a daily basis.  When collisions occur, the doors must be easy to fix to ensure continued daily operation.

The Solution

MAXDoor – the toughest vertical lift fabric door was selected.  MAXDoors tolerate corrosive environments and seal tight when closed limiting the amount of hot or cold air, pollens, and debris from entering the building.  Steel side frames ensure that MAXDoors maintain their strength during numerous cycling operations.  If a collision occurs, the horizontal beams are designed to flex and give way. Beams are quickly put back in place resulting in minimal downtime and no maintenance expense.  Multiple lifting belts are used providing additional safety and a slim chance of a door drop.

The Results

  • Minimize overuse of cooling and HVAC systems for indoor climate-controlled facilities
  • A door that will stand up to high-cycle daily operations
  • MAXDoors seal tight allowing for better air circulation with less toxins
  • Costly repairs and door downtime is drastically improved
  • Service life of a MAXDoor is 20-25+ Years even in a toxic and corrosive environment
  • Improved safety due to multiple lifting belts
  • Rectangular tube horizontal beams resist high wind
