Unistrut Brackets 45 Degree - Uses, Benefits and Load Capacity

Introduction to Unistrut Brackets 45 Degree

Unistrut is a popular brand of metal framing system used in various construction and industrial applications. It consists of channels, brackets, fittings and accessories that can be assembled into structural supports. One of the commonly used unistrut brackets is the 45 degree bracket, which enables assembling framing at a 45 degree angle.

What are Unistrut 45 Degree Brackets?

Unistrut 45 degree brackets, also known as angle brackets, are designed to connect unistrut channels perpendicularly at a 45 degree angle. They are U-shaped brackets that fit into the unistrut channel openings and get secured with bolts and spring nuts.

These brackets make it easy to create 45 degree angles with the unistrut framing system. They are available in various sizes to fit standard 1-5/8” and 1-7/8” unistrut channels. The brackets are made from steel and have a galvanized finish or a more corrosion resistant HDG coating.

Common Uses of 45 Degree Unistrut Brackets

Here are some of the common uses of 45 degree unistrut brackets:

• Assembling racking and shelving at a 45 degree angle
• Building equipment supports and machine guards
• Constructing safety railings and barriers
• Installing conveyor belt supports
• Mounting electrical cable trays
• Supporting mechanical pipes and conduits
• Creating bracing and framing for HVAC ductwork
• Building industrial workstations and furniture

The 45 degree brackets enable convenient angled assemblies for various industrial, construction and commercial applications. They can support lighter duty storage racks and shelving as well as heavy duty conveyors, walkways, railings and equipment supports.

Benefits of Using 45 Degree Unistrut Brackets

Here are some of the benefits of using 45 degree unistrut brackets:

• Versatility - They can be used to connect unistrut channels at 45 degrees for diverse constructions and mounts.
• Easy installation - Just slide the brackets into the channel and tighten with bolts and spring nuts.
• Strong support - Sturdy steel construction provides rigid 45 degree connections.
• Corrosion resistance - Galvanized and HDG finishes prevent rusting.
• Cost-effective - More affordable than custom fabricated brackets.
• Time saving - Eliminates the need to cut channels or weld custom angles.

With pre-formed 45 degree angles, the brackets save time and cost compared to fabricating on site braces and supports. They deliver reliable strength for industrial structures and equipment mounts.

Load Capacities

The load capacities of 45 degree unistrut brackets depends on the size of the channel and bracket. Typical load ratings are:

• 450 lbs for 1-5/8” unistrut channel
• 750 lbs for 1-7/8” unistrut channel

Heavier duty brackets designed for 2-3/8” and 3-1/2” unistrut channels can support over 2000 lbs. The load ratings are based on vertical loads, assuming the unistrut channels are supported horizontally.

For angled loads, the allowable load capacity reduces significantly. The ratings are also based on using properly torqued grade 5 or grade 8 bolts and spring nuts.

Sizing and Compatibility

The 45 degree unistrut brackets must be sized to fit the specific channel. Common sizes include:

• 1-5/8” x 1-5/8” x 12 gauge - fits 1-5/8” unistrut P1000 channel
• 1-7/8” x 1-7/8” x 12 gauge - fits 1-7/8” unistrut P1001 channel

Make sure to use the properly sized brackets that align with the channel openings. The brackets slot into the channel recesses and get bolted into place using unistrut spring nuts.

Installation Tips

Follow these tips for proper installation:

• Use 45 degree brackets on both channels being joined for stability.
• Slip the brackets fully into the channel ends before tightening.
• Tighten the bolts to recommended torque levels.
• Use washers under the bolt head and spring nut.
• Add cross bracing if needed for extra support.

Proper alignment, fitment and torque levels will ensure the sturdy construction of 45 degree unistrut assemblies and optimized load capacity.

Conclusion

Unistrut 45 degree brackets provide an easy and cost-effective method to connect structural framing at a 45 degree angle. Their pre-formed shape eliminates complex field fabrication. With proper sizing, fitting and torque levels, the brackets deliver robust and reliable 45 degree joints for industrial and construction applications.

They can support conveyors, work platforms, equipment mounts, railings and more at optimal 45 degree orientations. Overall, the 45 degree unistrut brackets enhance the versatility, speed and strength of unistrut framing installations.

FAQs

What are the common uses of 45 degree unistrut brackets?

45 degree unistrut brackets are commonly used for assembling racking, conveyors, railings, cable trays, ductwork, machine guards and other industrial structures at a 45 degree orientation.

What is the load capacity of 45 degree unistrut brackets?

The load capacity depends on the bracket and channel size. A 1-5/8" bracket has a 450 lb vertical load rating, while a 1-7/8" bracket can support up to 750 lbs vertically.

How do you install 45 degree unistrut brackets?

To install, fully insert the 45 degree brackets into the open ends of the unistrut channels being joined, then attach using bolts and spring nuts tightened to the recommended torque.

What size 45 degree bracket do I need?

Size the 45 degree bracket to match the specific unistrut channel size being used - either 1-5/8" or 1-7/8" channels. Brackets are available for other larger sizes too.

Can I use 45 degree brackets for angled load support?

Yes, but the allowable load capacity is significantly lower for angled vs. vertical loads. Cross bracing should be added for stability under angled loads.
