Hollaender Specs for Infill Panels
1.1
INFILL FOR RAILINGS
A.
Typical structural load requirement for IBC – withstand 50 lb. horizontal load on
an area equal to 1 sq ft.
B.
Perforated Metal Panel:
1.
Perforated Steel Sheet: of gage necessary to withstand loads indicated,
minimum 14 gauge.
2.
Pattern: 1/2" dia. holes spaced at 11/16" o.c.
3.
Frame: U-channel, corners welded and ground smooth. Where water
intrusion is likely, provide appropriate drain holes, minimum 3, in bottom
channel for evacuation of water.
4.
Entire panel to be treated with 4 step electro coat process, including pretreatment, electro-coat bath, post rinse, and bake oven, for corrosion
protection. Panel then to be powder coated with Rohm and Haas #239430
Silver Stardust powder coat, or color choice of architect.
5.
Panels to be attached to railing using Hollaender #145 panel retainers,
with appropriate slot width for panel thickness, and set screw for final
tightening. Panel retainer to be constructed of 6063 – T6 aluminum alloy.
C.
Wire Mesh Panel:
1.
2.
3.
4.
Wire Mesh infill panel: .120 wire diameter.
Pattern: 2 “ square.
Frame: U-channel, corners welded and ground smooth. Where water
intrusion is likely, provide appropriate drain holes, minimum 3, in bottom
channel for evacuation of water.

Other infill panels available as standard:
1. Square perforated panel, ¾ in. square, 1 in centers straight (shown below), 14 ga.
2. Other patterns of perforated metal and wire mesh are available, typically at some extra
cost that will vary depending on style desired.
Electrocoat System as practiced by our Automotive industry certified vendor





Pretreatment
o Cleans metal and prepares it for coating
Electrocoat Bath
o Water soluble liquid coating – see above diagram for components
o Contains de-ionized water, pigment, resin, solvent
Post Rinse
o 2-3 counterflowing rinses to remove excess paint solids, etc
Bake over
o 20 minutes at 325 deg F
Advantages of electrocoat process
o Allows coverage of all surfaces, especially edges of panels and interior cavities of
panels that may be missed by standard powder coating processes
o Formulated to provide superior corrosion resistance
