Service Doors

Rolling service doors are made up of multiple “slats” to form a curtain that rolls up around a barrel. Sometimes called steel rollup doors or rolling steel doors. These doors are mainly used on warehouse docks to secure a loading dock opening. The advantage of using a slatted door over a sheet door is that they are much stronger and more durable. In the case that a forklift should hit this type of door the damaged slat can be replaced instead of the whole door. Click here for more info about our service doors.

Standards:

  • 6″ minimum diameter structural steel pipe barrel
  • Oil tempered torsion springs on continuous cold-rolled steel shaft
  • Steel plate brackets attach to wall angles
  • Interior or exterior, face of wall or between jamb mount
  • Prime-painted galvanized steel hood
  • Chain operation with cast iron gears
  •  Interlocking prime-painted galvanized steel slats
  • Formed steel channel or structural steel angle guides and continuous wall angle mounting
  • Extruded aluminum or double steel angle foot piece with astragal

Options:

  • Climate-Guard Weather Stripping: Climate control is provided by the combination of a flat slat curtain, hood-baffle, guide weather stripping and astragal.
  • Thermal-Guard Insulation: An effective thermal barrier is created by the combination of 22 gage (min.) steel flat-faced slats, 3/4″ polyurethane foam, and 24 gage steel back slats.
  •  Increased Windload Capacity: Curtain designs to withstand windloads exceeding 20psf.
  • High Cycle Construction: Designs to provide up to 150,000 operating cycles for high use areas.
  • Perforated Slats: 3/64″ diameter holes on 5/64″ staggered centers in type 25 slats provide 30% open area for ventilation and visibility through the curtain.
  • Intermediate Grill: Partial grille curtain connecting type 30 slats above and below for ventilation and visibility.
  • Sloped or Stepped Foot piece: For uneven sill conditions.
  • Cylinder Locks: On foot piece or guide for extra security.
  • Pass Door: 3′-0″x6′-8″ hollow metal door in a steel frame for access through the curtain when closed; Frame is hinged to guide and swings clear to allow use of entire door opening when curtain is raised; handicap option, custom sizes, windows and special hardware available.
  • Galvanized Finish: On foot piece, guides, brackets and barrel.
  • Powdercoat Finish: On curtain, foot piece and guides.

Aluminum Options:

Offers a compact design and attractive appearance. Anodized extruded aluminum components combine lightweight with a smooth and bright finish and excellent corrosion resistance for a variety of applications. Counter door construction can be modified to provide for anodized aluminum service doors up to 12′ wide, 10′ high and 100 square feet.

  • Slat Type: Interlocking type 15 flat slats are extruded from 6063 alloy aluminum
  • Barrel: Steel pipe houses spring assembly and supports curtain with maximum deflection of .03 inch per foot of width
  • Springs: Torsion springs on continuous cold-rolled steel shaft
  • Brackets: Steel plate brackets attach to guides to support curtain and barrel
  • Guides: Extruded aluminum guides are bolted to aluminum wall angles and fitted with nylon pile wear strips
  • Foot Piece: Extruded aluminum tubular foot piece with astragal
  • Hood: Formed from aluminum sheet and reinforced with top and bottom flanges to limit deflection
  • Locking Mechanism: Slide bolt locks and optional cylinder lock
    Aluminum slats, foot piece, guides and hood are clear anodized. Steel brackets receive one coat of rust inhibiting grey primer. Dark bronze and other color anodized finishes are optional.
  • Operation: Push-up is standard and awning crank on larger sizes is standard (awning crank should be considered when doors are to be operated over a deep counter over 7′ high). Optional chain hoist or motor operator is available.

Steel and Stainless Steel:

Strength and durability of a rolling service door with compact design and clean appearance. Although primarily used as a closure on counter openings, it may also be used on openings providing walk-thru or drive-thru access. Counter door construction can be modified to provide for stainless steel service doors up to 16′ wide, 10′ high and 144 square feet.

  • Slat Type:  Interlocking type 18 flat galvanized steel or stainless steel slat options
  • Barrel: Steel pipe houses spring assembly and supports curtain with maximum deflection of .03 inch per foot of width
  • Springs:  Torsion springs on continuous cold-rolled steel shaft
  • Brackets: Steel plate brackets attach to guides to support curtain and barrel
  • Guides: Box shape guides formed from steel or stainless steel
  • Foot Piece:  Single angle or tubular foot piece with astragal
  • Hood:  24 gage galvanized or stainless steel hood reinforced with top and bottom flanges to limit deflection
  • Locking Mechanism: Slide bolt locks on single angle foot piece and cylinder lock on optional tubular foot piece
  • Finish: Galvanized steel slats and hoods are pre-finished with a baked on grey polyester primer before forming. Steel foot piece, guides and brackets receive one coat of rust inhibiting grey primer. Exposed stainless steel provided with #4 finish.
  • Operation: Push-up to 14′ wide and awning crank on larger sizes is standard (awning crank should be considered when doors are to be operated over a deep counter over 7′ high). Optional chain hoist or motor operator is available.

Specifications:

  • Mounting: Face of wall or between jamb
  • Operation: Push-up to 8′ wide and high and chain hoist on larger sizes is standard; awning crank, crank box or motor operation is optional
  • Automatic Closing: Thermally activated by 165 degrees fusible links, with the closing speed regulated by a governor device operative only during automatic closing
  • Curtain: Interlocking slats are roll formed from galvanized steel coil. Gage of slats is as required by the listing. Endlocks are riveted to slats to maintain curtain alignment. Bottom of curtain is reinforced by a double steel angle foot piece.
  • Guides: Steel channels or structural steel angles from curtain guides are bolted to structural steel wall angles. Sizes of guides are as required by the listing.
  • Brackets: Steel plate brackets are bolted to wall angles to support curtain and barrel and provide mounting for hood.
  • Hood: Formed from minimum 24 gage galvanized steel sheet, reinforced with top and bottom flanges to limit deflection. A thermally released integral flame baffle is provided when required by the listing.
  • Locking: Chain lock with chain operation and slide bolt locks with push-up or crank operation.
  • Finish: Slats and hoods are pre-finished with a baked on grey polyester primer before forming. Foot piece, guides and brackets receive one coat of rust inhibiting black primer.
