4-Hole Strut Tee Plate
Build strong, clean T-connections between intersecting sections of strut channel. This flat four-hole tee plate bridges the joint with three mounting points across the main channel and a fourth mounting point on the adjoining channel.
Its versatile flat design makes it useful for equipment frames, solar supports, shelving, utility structures and other strut assemblies built indoors or outdoors. The Hot Dip Galvanized finish adds durable corrosion protection wherever the finished structure is installed.
Why You’ll Love It
- Clean T-connections — joins intersecting strut channels in the same plane
- Four-point attachment — helps keep the joint secure, square and properly aligned
- Indoor or outdoor versatility — ideal for workshops, equipment rooms and exposed structures
- Long-lasting finish — Hot Dip Galvanized for dependable corrosion protection
Hot Dip Galvanized hardware is not limited to outdoor projects. Its heavy, bonded zinc coating provides excellent durability in workshops, equipment rooms, utility spaces and other indoor installations where condensation, humidity or long service life may be a consideration.
For outdoor structures, the same coating offers dependable protection against rain and changing weather. It is a versatile upgrade that helps keep your strut assembly looking and performing its best—indoors or out.
A Better Way to Build T-Junctions
The tee plate lies flat across the face of the strut assembly. Three holes run across the horizontal section, while the fourth mounting hole secures the intersecting channel below it.
This creates a straightforward connection for frames and supports where one section of channel terminates against another. The broad top section helps maintain alignment across the joint, while the centre stem ties the intersecting channel into the assembly.
Durability for Any Installation
During hot dip galvanizing, the steel plate is immersed in molten zinc. The zinc reacts with the steel to form multiple bonded alloy layers beneath a protective outer zinc coating.
This heavier coating provides greater long-term corrosion protection than basic zinc plating. It is a valuable feature for exposed outdoor structures, but it also makes this plate an excellent choice for durable indoor assemblies that you want to build once and rely on for years.

Frequently Asked
What type of connection is this tee plate designed for?
It is designed to connect strut channels that meet in a T-shaped arrangement on the same plane. Three mounting holes run across the main channel, while the fourth hole secures the intersecting channel through the plate’s centre stem.
Can I use this tee plate indoors?
Absolutely. Hot Dip Galvanized fittings are an excellent choice for workshops, equipment rooms, warehouses, utility spaces and other indoor installations. The durable finish is especially useful in areas that may experience humidity, condensation or occasional moisture.
The additional corrosion protection also makes it a great option for indoor structures where long service life and minimal maintenance are priorities.
Is it suitable for outdoor installations?
Yes. The Hot Dip Galvanized finish provides durable protection against rain, condensation and changing weather, making this plate well suited to solar racking, outdoor equipment frames and other exposed structures.
For the best complete assembly, use channel, strut nuts, bolts and adjoining fittings with finishes selected for the same environment.
How does Hot Dip Galvanized differ from Zinc Plated?
Both finishes use zinc to help protect steel from corrosion. Zinc Plated hardware receives a relatively thin, smooth coating and is a practical option for dry, protected installations.
Hot Dip Galvanized steel is immersed in molten zinc, creating a much heavier coating with bonded zinc-alloy layers. It provides greater long-term corrosion protection while remaining equally suitable for indoor use.
Why can the galvanized surface look slightly uneven?
Hot Dip Galvanized hardware may have a duller, more textured or less uniform appearance than smooth Zinc Plated hardware. These natural variations result from the heavier galvanizing process and do not indicate a defect.
The protective coating—not a perfectly uniform cosmetic surface—is what gives the fitting its excellent durability and corrosion resistance.
Is this a bent or formed bracket?
No. This is a flat T-shaped plate designed to mount across the face of channel sections meeting in the same plane. If your channel sections meet on different planes, a formed angle or another style of fitting may be more appropriate.
Should I use all four mounting holes?
Yes. The plate is designed to be secured at all four mounting points. Using every hole provides the intended alignment and support across the completed T-connection.
