Unistrut P5501 1-5/8'' x 4-7/8'' Double Channel, 12 Gauge

Sku:

P5501

UOM: LGT

Product Details

Unistrut's P5501 (back-to-back solid) Channel is our 12 gauge channel that is commonly used for trapeze supports, siesmic bracing, ceiling grids, pipe, conduit, duct and cable tray supports, racks, and other general framing. For application examples, refer to our Application Showcase. Product dimensions are 1 5/8" wide x 4 7/8" tall x 12 ga. thick, solid. Punched holes are also available for ease of installation. The advantage of a back-to-back channel is the versatile connection points and superior load capabilities. Our P5001 is available in the following finishes: Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD) and Aluminum (EA).


Unistrut Buffalo is a division of Eberl Iron Works, Inc.

MATERIAL

Unistrut channels are accurately and carefully cold formed to size from low-carbon strip steel.

All spot-welded combination members, except P1001T, are welded 3" (76 mm) maximum on center.

STEEL: PLAIN

12 Ga. (2.7 mm), 14 Ga.(1.9 mm) and
16 Ga. (1.5 mm) ASTM A1011 SS GR 33

STEEL: PRE-GALVANIZED

12 Ga. (2.7 mm), 14 Ga. (1.9 mm) and
16 Ga. (1.5mm) ASTM A653 GR 33

For other materials, see Special Metals or Fiberglass sections.

FINISHES

All channels are available in:

  • Perma Green III (GR)
  • Pre-galvanized (PG), conforming to ASTM A653 G90
  • Hot-dipped galvanized (HG), conforming to ASTM A123
  • Plain (PL)
  • Unistrut Defender™ (DF), conforming to ASTM A1046

*** Perma Green finish is a commercial grade finish, and as such scuffs and scratch marks are to be expected. If a flawless finish is desired, it is recommended to apply a matching touch up paint ***

DIMENSIONS

Imperial dimensions are illustrated in inches. Metric dimensions are shown in millimeters and rounded to one decimal place.

STANDARD LENGTHS

Standard lengths are 10 feet (3.05m) and 20 feet (6.10m). Tolerances are ±1⁄8" (3 mm). Special lengths are available for a small cutting charge with a tolerance of ±1⁄8" (3 mm).

CURVED CHANNEL

LOAD DATA

All beam and column load data pertains to carbon steel and stainless steel channels. Load tables and charts are constructed to be in accordance with the SPECIFICATION FOR THE DESIGN OF COLD-FORMED STEEL STRUCTURAL MEMBERS 2007 EDITION published by the AMERICAN IRON AND STEEL INSTITUTE USING ASD METHOD. Loads are based on 33 ksi steel cold formed to 42 ksi.

Notes:
* Load limited by spot weld shear.
** KL⁄r > 200
NR = Not Recommended.
1. Beam loads are given in total uniform load (W Lbs) not uniform load (w lbs/ft or
w lbs/in).
2. Beam loads are based on a simple span and assumed to be adequately laterally
braced. Unbraced spans can reduce beam load carrying capacity. Refer to Page 62
for reduction factors for unbraced lengths.
3. For pierced channel, multiply beam loads by the following factor:
"KO" Series........95%    "T" Series...........85%
"HS" Series........90%    "SL" Series.........85%
"H3" Series.........90%   "DS" Series........70%
"WT" Series........85%
4. Deduct channel weight from the beam loads.
5. For concentrated midspan point loads, multiply beam loads by 50% and the
corresponding deflection by 80%. For other load conditions refer to page 18.
6. All beam loads are for bending about Axis 1-1.
