Fabricate revolving door individual assemblies using reinforced and face welded surface joinery, with all welds dressed flush and finish blended to match adjacent surfaces.
Where bends in sheet forming are required, all stretch lines and die marks shall be refinished to blend with adjacent surfaces. Door shall be fabricated with no visible glazing stops except those required for the wall bottom rail glazing molds. No visible fasteners shall be used except those necessary for the application of manufacturers hardware, and bottom wall rail glazing mold.
Ceiling - To be fabricated of 16-gauge stainless or 14-gauge bronze. 14-gauge aluminum ceiling sheets shall be used on aluminum doors.
Ceiling Lights - Furnish manufacturers standard ceiling lights with lamps and lamp fixtures. Electrical wiring and hookup by an appropriately licensed electrical contractor.
Center Mullion - The curved, arcing walls surrounding the wings and supporting the canopy (cornice) usually are designed with a center support frame, i.e. separating the inside from the outside, at the halfway point on the door. When a center mullion (vertical metal or wood support frame part) is used, the arced (lites of) bent (or curved) glass fit in to both sides of it.
CIeaning, Initial - The installation crew should maintain the work environment in a reasonably clean condition throughout the installation period, so that the new revolving door(s) will be without any evidence of deterioration at the completion of its erection. But a construction environment (e.g. in a newly constructed building) is often dusty, with dirty floors and sub-contractors tracking dirt and metal fragments as they walk. The installation crew (and later the general contractor, see below) needs to be able to protect the floor directly under the revolving door and also a nearby staging area for the wings, glass wall sections, and other door components as they are needed for proper assembly.
Cleaning, Final - Often a revolving door is installed in a new building - at the same time that other construction activities are being done. Its location, usually at the front-center of the building, starting as a large opening, can encourage other sub-contractors to walk through the opening, even during door erection. The general contractor shall be responsible for protection of installed equipment, protecting the exposed surfaces against damage by other subcontractors, staining, abrasion or other harm, and shall be responsible for the final cleaning of the glass and finished surfaces as construction activities reach their completion.
Common Problems - It is worth noting that there are two site problems that most often impair a new revolving door's proper installation. First, the floor is not perfectly level or not shaped properly. Second, not enough overhead clearance.
Floor Problem - In order for a revolving door to have even pressure on all moving surfaces allowing for both smooth movement and weatherstripping protection, it is necessary for all surfaces to be level or accurately arced. In our factory we pre-install every door on one of our level metal erection pads. The entire door is fully assembled: walls, canopy/cornice, speed control, electronics (for automatic or security doors), center shaft, and wings. All moving (and electronic) parts are tested. As it is disassembled, everything goes directly from there to the shipping department to ensure that nothing is missing - from our shop - to your door installation site.
When a revolving door is used as a building entrance some draftsmen want to slant or angle the floor area outward to ensure storm rain run-off. While it is a good practice to slope ground surfaces away from a building for water run-off, it is simultaneously imperative that the round floor portion that is to be directly beneath the revolving door must be level surfaced for the reasons cited in the previous paragraph. But arriving at a job site - with a fully factory pre-tested door, ready for assembly - a crew first checks the floor with a level to first determine if the door can even be installed. This is the number one construction site problem that we encounter!
Overhead Clearance - At time of door installation it is absolutely necessary to be able to climb into the cornice/canopy from above during the door's erection. The installation team must be able to (first install the walls into place, then lift and move the canopy into position, then) lower the canopy onto the walls; long bolts are then lowered in and tightened to secure the cornice/canopy to the wall mullions (frame supports) below.
For a manual door, the manual speed control (placed directly above the center shaft) will need to be shimmed to the exact center point, and as a final step oil is poured in and then the unit is sealed, from above.
For an automatic or automatic-security door, the electronics and motor installed above needs to be fully accessible during installation time. With a 12" minimum clearance, it is necessary for one team member to be able to fully climb into the canopy with tools and testing equipment.
Emergency Collapsing Mechanism - CoIlapsing mechanism shall permit the wings to fold to emergency exit position. Pressure setting shall be capable of being adjusted from 60 pounds to a maximum setting of 180 pounds. Unless otherwise specified, revolving door units shall be initially installed with a pressure setting of 120 to 140 pounds. Each wing's collapse setting is pre-tested in our factory, prior to shipment.
The (wing break/collapse pressure) adjusting device on IRD doors is accessible without removal of wings, centershaft or discs. The pressure setting shall be preset and tested in the factory and shall only need to be re-adjusted in the field to meet the specific needs of the building.
Documentation verifying all in-house testing of satefy devices will be delivered to the architect and owner.
Glass - Furnish glass and glazing in strict accordance with governing codes. IRD recommends at least one-fourth inch (1/4") thick clear tempered glass for wings, and for curved enclosure walls select one of the following in coordination with design drawings
If design requires a total of four lites of single bend/bent glass (i.e. 4 sections, or 4 pieces of arced glass) per revolving door: use one-fourth inch clear annealed (heat-treated) float; or five-sixteenths inch clear laminated safety glass. lf instead a total of two lites (pieces) of single bend glass are needed (i.e. with no center mullion) per revolving door: use one-fourth inch or three-eighths inch clear annealed float; or seven-sixteenths inch or nine-sixteenths inch clear laminated safety glass, as appropriate, per your specific plans.
Note: If double bend or triple bend glass is required, consult with factory for size limitations and location placement of butt joints.
lf ceiling glass is required: use one-half inch clear tempered float; or nine-sixteenths inch clear laminated safety glass; refer to your specific plans for exact details - overriding these general/typical specifications.
Hardware - Manufacturer's standard push bars and surface type locks with standard cylinder. Surfaces of hardware shall match door finish, unless customer desires complimentary contrasting metals or woods to be used.
InstaIlation/Erection - Inspect and examine the areas and conditions under which revolving doors are to be installed. Do not cut, trim, weld or braze component parts in any manner that could damage finish, decrease strength or result in a visual imperfection or a failure in performance. Set revolving doors plumb, square, level and true, all in accordance with manufacturer's erection drawings and approved shop drawings.
Speed Control - The overhead speed control device shall limit the turning speed to 12 rpm, shall be 100-1 gear ratio and be designed to prevent rapid acceleration. The mechanism shall provide smooth and effective braking action with brake shoes operating in an oil bath.
Documentation for the speed control, verifying all in house testing of safety devices will be delivered to the architect and owner.
Optional FIoor Type (Model FL & FLP) Speed Control (i.e. mounted directly below the door's center shaft) - (See details, in section below)
Optional Overhead Roll-lt-Side (OHRA) Type Speed Control - (See details, below)
Storage and Handling - Deliver metal work to project site by "speciaI commodities" type carrier, fully protected by padded blankets, scheduled to arrive at time of erection sequence requirement.
WaIls - To be fabricated of formed sheet .048 inch minimum thickness with hairline joints in the bottom rail convex side only. No visible glazing stops shall be used except for the removable mold at the bottom rail.
Weather Stripping - Weather strips shall be installed in top rails, stiles and bottom rails; designed to properly engage the curved enclosure walls, revolving door ceiling and floor. Special adjustment feature will allow for three-eighths inch adjustment, if needed later.
Wings - To be fabricated of formed
sheet .062 inch minimum thickness with no visible joints, except at inside
stile. No visible glazing stops shall be used. Overall wing thickness 1
3/4 inches minimum (except for Comet design with its "all-glass" wing construction).

Manufacturer
International Revolving Door Co. (IRD) alternate sub-assembly manufacturers may be considered, but must obtain approval 10 days prior to bid date. For approval to be considered, manufacturer must submit current literature, project list of previous successful installations in air supported structures, indicating date of substantial completion, as well as name and telephone number of individual responsible tor building's operation.
Air Leakage Performance - Manufacturer to submit certified laboratory test report, acceptable to the architect, verifying that maximum air leakage does not exceed 25O CFM at 5 PSF with two door wings engaged and does not exceed 150 CFM with four door wings engaged. Tests to be accomplished with normal operating hardware clearances and shall match those actually installed at the job site.
Testing After Roof InfIation - Testing of air leakage performance shall be pertormed after revolving doors have been installed, to demonstrate that installed product meets air leakage specifications. Manufacturer of revolving doors will be responsible for testing charges only if tests fail, and shall replace faulty components, make necessary adjustments, to satisfy air leakage performance at no additional costs to the owner.
Weather Stripping - Heavy-duty,
double-rubber, and rubber-felt combinations, installed at top rails, stiles
and bottom rails; designed to properly engage the ceiling, enclosure walls
and level floor. For existing older doors, IRD maintains a parts
inventory, ready for shipment. Weatherstripping and other parts
can become worn and need replacement after many years of service.

Guarantee
International Revolving Door Company (IRD) (along with applicable installer, if different) - shall guarantee installation to be free from defects in materials and workmanship for a period of one year following initial installation date.
Additionally, the manual speed control (except FLP, below) shall be guaranteed for five years and shalI be adjusted, repaired or replaced should it fail to perform in any respect to the specifications as outlined herein at no additional cost to the owner.
FLP speed control shall have a Limited One Year Conditional Guarantee. Manufacturer retains the right to inspect sealant (by stone contractor) around its floor pan after installation and prior to any removal for repair - if sealant has been removed the warranty is voided.
The warranty for power operated doors (automatic and automatic-security doors) consists of one year for workmanship and materials and six months for parts, following date of installation.
Note: We reserve the right to make design
improvements or changes from the specifications described or shown herein
as may be deemed necessary, without formal notice. There is no other specified
warranty on glass or the door finish.
Installation
After factory testing (full pre-assembly of door in shop) is completed, the IRD revolving door is disassembled, packed and shipped as a unit, and reassembled and installed exactly as tested, by use of accurate shop drawings and under the supervision of factory-trained personnel.
The two most common problems (also noted above) for the on-site installation of your new revolving door are:
Floor pad - either not precisely level, or not centered properly for the roughed-out doorway opening. Unfortunately, floor level variance impacts the revolving door with every revolution, every day causing either gaps or rubbing spots. The floor must be as close to level as possible!
Clearance height - During assembly it is
typical to first put the door's walls into position, then to raise the
canopy (cornice) into position from one side (either from the interior
or exterior side), move it across - to center over the door's location,
then lowering it onto the walls, where it is then bolted to the walls.
In order to do this, a few inches of unobstructed clearance above the entire
canopy must be available during installion! And usually one installer
must physically climb into the canopy in order to tighten the bolts to
the walls down properly. And the manual speed control or the electronics
in the cornice (canopy) may need to be accessed from above later.
Delivery
Prompt shipmenf of a standard-sized aluminum
door 6 foot 6 inch x 7 foot (See Page 8) with dark bronze or 215-R1 clear-anodized (was called: 204R1) finish
can often be accomplished in two to three weeks. A similar aluminum model
with diameter and/or height dimensional changes may considerably extend
the delivery time, starting after receipt of customer approved drawings
and samples. Custom-built models inherently require additional time to
complete.
Standards
lntemational Revolving Doors conform
to and are in compliance with BOCA's Basic Building Code, lCCBO's Uniform
Building Code, SBCCI's Standard Building Code and NFPA's Life Safety Code.
Maintenance
Every three months, at least, fold ("break" or collapse) wings to the side, and check operation.
Use a clean, dry paint brush to remove any accumulation of dirt from areas around the hold plunger and V-recess. Wipe off guide pins and pilot pin on hangers and wipe out grooves in disc with a slightly oiled cloth.
Under normal use, the only other maintenance necessary in the first few years is the occasional replacement of airlock (weather) strips.
Repairs
Should repairs be necessary, IRD maintains a stock of parts and IRD's head office has a file of installation drawings for current production models. For older doors, it may be necessary to fabricate custom replacement parts.
Revolving Door Accessories/Options
Locks
Most commercial door installations require the ability to physically lock the two interior wings at night or on weekends, etc. Keyed locks are normally mounted to the bottom of two of the four wings, with appropriate small holes drilled into the existing floor in order to accomodate the "dead-bolt" type mechanism.
Solid bronze locks, chrome plated on stainless steel and natural color aluminum doors, or finished to match door color, are surface mounted at either the top or bottom of two wings. Lock parts are bronze or stainless steel, with standard cylinders and keys. Lock installs at the floor (most common) are always recommended for doors over 7 feet 6 inches high, or for doors with custom-built glass ceilings.
Custom Push Bars (Optional Extra)
| Push bars of a wide variety may be used on IRD door wings. Round or flattened bars, bars of contrasting metals, bars going through the glass plates, and bars of wood and metal are available on virtually any type of door. The only limitation is that the design must still allow the wings to bookfold into the emergency collapsing (wing "break") position. |
 |
Curved Metal (instead of mostly glass) Walls - Design #1 (Optional Extra)
IRD offers the Design #1 wall for
instances when less visibility is needed or desired. This all-metal wall
fits many design needs. The Design #1-U wall is also available with concave
side finish only, for use in solid walls or part metal/part glass walls.
(See below, left.)
 |
 Model OHRA (Optional Extra) Roll-Aside Wings (See above.) This feature allows door wings to fold and then roll to one side, permitting long or bulky items to pass freely through the entrance. |
Manual Speed Control - Model FLP (Optional Extra) (Shown below, left.)
Use this model when door has both a glass ceiling and stone floor covering the manual speed control. Note the recessed floor pan.
Also, when considering an in-floor manual speed control (due to a glass ceiling or other constraints) always consider potential storm damage if standing water may infiltrate or dust accumulation due to regular winds - if the door will be at the building's exterior. And maintenance access to a floor-mounted manual speed control is also more difficult as the wings and center shaft must first be removed from above.

Other Options
IRD will custom build your: revolving, revolver, rotating, circular, spinning, round, axis centered entrance or limited or controlled-access door - according to your construction needs.
International Revolving Door Company (IRD) regularly works with corporate commercial or industrial interests, or government agencies to install specific door options. A fine dining establishment may want an exotic manual hardwood door made of oak, walnut, cherry, ash or other hardwood; or a government agency may require a fully automatic bullet-resistant security door with extra lights or cameras built into the construction. Why, there are even a couple of residential revolving doors that have been installed.
If the customer wants lights and speakers built into the canopy's ceiling, we are glad to pre-install these. A UPS (uninterruptible power supply) can ensure operation in case of local power outage. Need security cameras or special emergency parts installed? Let us work with you to create and manufacture the best revolving door according your specific needs.
