Pre Galvanized Steel Strut Washers
What are pre galvanized steel strut washers? Pre galvanized steel strut washers are square washers made to fit metal strut channel, with a pre-galvanized zinc coating for corrosion resistance. They seat between the channel lips to spread load and hold bolts or threaded rod in place, matching the finish of standard strut and fittings.

Why pre galvanized for strut washers?
Pre-galvanized steel is zinc-coated before forming, giving a clean, uniform, corrosion-resistant finish that matches the pre-galvanized strut channel and fittings used across electrical, plumbing, and mechanical support systems. The washer is squared to seat between the channel lips so it registers against the strut and does not spin or pull through, spreading the clamping load of a bolt or threaded rod along the channel. This suits the indoor and covered conditions where most strut systems are installed. For heavy outdoor or wet exposure, a hot dipped galvanized or stainless option offers more corrosion resistance.
Why choose pre galvanized steel strut washers
- Fits strut channel: squared to seat between the channel lips.
- Matching finish: pre-galvanized to match strut and fittings.
- Corrosion resistant: zinc coating for indoor and covered use.
- Spreads load: distributes clamping force along the strut.
Common applications for pre galvanized strut washers
- Unistrut and strut channel assemblies
- Electrical and cable support systems
- Plumbing and mechanical pipe supports
- Threaded rod and bolt connections in channel
