DETAILS
Product Details
Unistrut's P3300T channel is commonly used for trapeze supports, seismic 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 7/8" tall x 12 ga. thick. Slots are sized for a 1/2" threaded rod or fastener. This slotted option is popular because it's adjustable, yet has modest load capacity loss versus the solid version. It has 85% of the capacity of the solid version of the profile. Our P3300T is available in Pre-Galvanized (PG), Unistrut Defender (DF), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), ZInc Dichromate (ZD), Stainless Steel (SS or ST) and Aluminum (EA).
Unistrut Buffalo is a division of Eberl Iron Works, Inc.

Material/Finish
MATERIAL
Unistrut channels are accurately and carefully cold formedto 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 orFiberglass sections.
FINISHES
All channels are available in:
- Perma Green III (GR)
- Pre-galvanized (PG), conforming to ASTM A653 G90
- Hot-dipped galvanized (HG), conforming toASTM A123
- Plain (PL)
- Unistrut Defender™ (DF), conforming toASTM 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. Metricdimensions are shown inmillimeters and rounded to onedecimal place.
STANDARD LENGTHS
Standard lengths are 10 feet (3.05m) and 20 feet (6.10m).Tolerances are ±1⁄8" (3 mm). Special lengths are availablefor a small cutting charge with a tolerance of ±1⁄8" (3 mm).

LOAD DATA
All beam and column load data pertains to carbon steeland stainless steel channels. Load tables and charts areconstructed to be in accordance with the SPECIFICATIONFOR THE DESIGN OF COLD-FORMED STEEL STRUCTURALMEMBERS 2007 EDITION published by the AMERICAN IRONAND STEEL INSTITUTE USING ASD METHOD. Loads arebased on 33 ksi steel cold formed to 42 ksi.

Notes:
* Load limited by spot weld shear.

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.
