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.

Notes:

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.

FAQs

What size is the Unistrut p3300? ›

Features: Product dimensions are 1 5/8" wide x 7/8" tall x 12 ga.

How much weight will Unistrut hold? ›

Average Weight Limits for Unistrut

Meanwhile, in the P5500 series, maximum allowable load limits range from 330 pounds to 3,270 pounds. Overall, Unistrut systems can always manage loads of at least 40 pounds, and you can easily find Unistruts that hold upwards of 3,000 pounds.

What is the standard size of the Unistrut channel? ›

The standard lengths for nearly all Unistrut channels are 10 feet, or 20 feet (though a few are available in 16 foot lengths). So, bear in mind that channel will need to be transported on a box truck or flat bed, unless you have small quantities cut to length for UPS shipping.

What is the alternative to a strut channel? ›

Walraven RapidRail® is our unique light rail fixing system that we developed as a lightweight, easy to install alternative to traditional strut channel.

Is all Unistrut the same size? ›

The vast majority of Unistrut channel sections come in 10' and 20' lengths.

What grade steel is Unistrut? ›

Unistrut metal framing is available in several grades of stainless steel, including Type 304 (SS), Type 316 (ST), and Type 321. Stainless Steel channel load data is the same as the steel channel sections.

Why is Unistrut so expensive? ›

These increases are due to supply chain distruptions caused by the Covid-19 pandemic, which have further led to: Soaring Steel Prices. Material Shortages. Rising Fuel Prices.

What is the difference between 12 gauge and 14 gauge Unistrut? ›

12 gauge offers a 0.098" sheet thickness minimum, while the 14 gauge offers a 0.070" sheet thickness minimum. The 12 gauge sheets are 40% heavier than the 14 gauge sheets. 12 gauge sheets are designed for dynamic pressure, the 14 gauge sheets are designed for static pressure. 12 gauge systems have a lifetime warranty!

What is the difference between power strut and Unistrut? ›

As pointed out previously, the only difference between Unistrut and Power-Strut channels is in the shape of the inturned edge of the channel. There is no doubt that both perform the same function and in the same way, and equally efficiently.

How far apart should Unistrut be? ›

For EMT, the required support is within 3 feet of each termination, and a minimum of every 10 feet.

What is the difference between Unistrut and Superstrut? ›

However, the thickness of the steel used to manufacture the channels differs. Superstrut's 1-⅝” line of channels is available in both 12 and 14 gauge, while Unistrut's 1-⅝” channel series is available in a wider range of material thicknesses, including 12, 14, and 16 gauge.

How long can you get Unistrut? ›

Standard lengths are 10 feet (3.05m) and 20 feet (6.10m). Tolerances are +Vx" (3.2 mm) to +Vi" (12.7 mm) to allow for cutting. Special lengths are available for a small cutting charge with a tolerance of ±!/s" (3.2mm).

What is another name for Unistrut? ›

Channel Strut, which is commonly referred to by many different names including strut, Unistrut, channel and strut channel, are all referring to one of the most versatile fastening tools on the market.

Is it better to buy a complete strut assembly? ›

Convenience – With everything needed for the repair in a single component, a strut assembly means you don't have to source other parts. All New Components – With all new components, you don't have to worry about the coil spring or any other part wearing out before your new strut does.

Can Unistrut be used as a cable tray? ›

In summary, whether you're looking to improve safety, efficiency, or organization within your facility, Unistrut Cable Tray is a solution worth considering. Trust it to keep your cables organized, secure, and easily accessible.

How do you identify Unistrut? ›

Genuine fittings and specialty items like trolleys are stamped with the name “Unistrut” and the corresponding part number. The finish, shape, and dimensions of imitation parts often closely match Unistrut materials, but the lack of proper markings makes counterfeit parts easy to spot.

What is the thickness of Unistrut 41x41? ›

Unistrut 41mm x 41mm, 2.5mm Slotted Channel Sections. Available in 3m and 6m lengths of Pre-Galvanised Steel, Hot Dip Galvanised Steel or Stainless Steel. These standard duty channel sections have been designed to provide a versatile and economical solution to industrial framing and support problems.
