Entrance doors shall be as detailed and manufactured by REBCO, Incorporated, Paterson, NJ.
MATERIALS – Sections shall be extruded 6063-T5 aluminum alloy and temper suitable for special anodic finishing. Major tubular portions of door stiles and rails shall be a nominal .125" thickness and glazing molding shall be .050" in thickness. Material dimensions are subject to normal aluminum extrusion tolerances.
WORKMANSHIP – Entrance units shall be completely factory assembled and include doors, frames, sidelights, transoms and hardware as required. Corners of doors shall be accurately joined and fitted with a flush hairline joint. Doors shall be of triple reinforced construction having reinforced anchor blocks, coin punched, interlocked into the top and bottom rails, bolted to the stiles and secured in place with dome lock washers, then welded at the top and underside of each corner. The weld shall thoroughly penetrate the material and produce a complete fusion of metal between stiles and rails. All welding shall be on unexposed surfaces to prevent pitting, discoloration, weld halo or other surface imperfections. No mechanical joints will be permitted. Glazing of doors shall be of E.P.D.M. or of vinyl type gasket. No screws shall be needed to secure glazing stops in place. Standard stops are available for 1/4", 5/8" and 1" glazing. Special taller stops for 1" glazing are also available. All cutouts, recesses, mortising or milling operations required for hardware shall be accurately made and reinforced with backing plates as required to insure adequate strength of the connection.
Lock stiles for single doors shall be beveled type. Lock stiles for pairs of doors shall be two-piece with adjustable nosing and rubber grommets for ease of adjustment. Meeting stiles at pairs of doors shall each have adjustable two piece nosing and stile, one of which shall have two continuous weather piles for maximum weathering between doors.
Doors (without intermediate rails) shall be equipped with top rail adjustment screws for minor field adjustments after installation. All fasteners for push and pull hardware shall be stainless steel. Butt hinges shall be full mortise, non-ferrous ball bearing hinges.
PERFORMANCE REQUIREMENTS – Entrance units shall meet the following performance criteria: (Testing procedures and certified test results available on request).
Air Infiltration: For single acting offset pivot or butt hung entrances in the closed and locked position, the test specimen shall be tested in accordance with ASTM E 283 at a pressure differential of 6.24 psf for single doors and 1.57 psf for pairs of doors. A single 3'0" x 7'0" entrance door and frame shall not exceed 0.05 cfm per linear foot of perimeter crack. A pair of 6'0" x 7'0" entrance doors and frame shall not exceed 1.0 cfm per linear foot of perimeter crack. (Blade gasket strip in an aluminum extrusion applied to the exterior surface of the bottom rail with exposed fasteners necessary to meet the specified performance test results.)
Structural: Corner strength shall be tested according to REBCO's dual moment load test procedure and certified by an independent testing laboratory to ensure weld compliance and corner integrity.
Structural Uniform Load Test: Single doors: 90 psf
Pair of doors: 60 psf
Forced Entry Resistance:
300 lbs. inward and outward without failure.
FINISH – All exposed surfaces including the edges of stiles shall be finished. Standard available finishes are as follows: Clear anodized, Dark bronze hardcoat and White electrostatically applied polyester paint. Other custom finishes are available.
HARDWARE – Hardware for aluminum entrance doors shall be furnished and/or installed by the door manufacturer and shall include the following items: Push-Pull Hardware, Maximum Security Deadlock with Cylinders, Flush Bolts (pairs of doors only), Center Pivots, Offset Pivots, Butt Hinges, Continuous Hinges, Thresholds, and, as specified, Concealed Overhead Closer, Floor Closer or Overhead Surface Closer.
SUPER STRENGTH SERIES "N" - Narrow Stile Door – Standard door thickness of 1-3/4" with 2" vertical stiles, 2-3/4" top horizontal rail and 3-7/16" bottom horizontal rail. A 6-13/16" or 10" bottom horizontal rail, as well as other available horizontal rails may be substituted for extra strength and design flexibility.
SUPER STRENGTH SERIES "M" - Medium Stile Door – Standard door thickness of 1-3/4" with 3-1/2" vertical stiles, 3-7/16" top horizontal rail and 6-13/16" bottom horizontal rail. A 10" bottom horizontal rail, as well as other available horizontal rails may be substituted for extra strength and design flexibility.
SUPER STRENGTH SERIES "W" - Wide Stile Door – Standard door thickness of 1-3/4" with 5" vertical stiles, 5" top horizontal rail and 6-13/16" bottom horizontal rail. A 10" bottom horizontal rail, as well as other available horizontal rails may be substituted for extra strength and design flexibility.
MID-RAILS – Extruded aluminum mid-rails of 3/8", 2", 3", 4-1/2", 5-3/4", 7-9/16", and 10" are available to add greater strength and durability, conceal an exit device from view or divide the glazing area of the door.
ALUMINUM PANEL INSERTS – Double face, textured-finish aluminum panel inserts for use below extruded aluminum mid-rails are available in 1/4", 1" and 1-1/2" thickness to effectively meet the demands of high traffic areas.
TRUE DIVIDED LITES – Vertical and horizontal 3/8" solid intermediate rails, welded in place to form various grid patterns are available and provide the strength and flexibility not available from surface applied or internal muntins.
A full line of custom, Designer Series entrance doors is also available.
