4-Hole Strut Tee Plate

Choose Electro-Galvanized / Zinc Plated for excellent everyday corrosion protection, a smooth appearance and strong overall value. It is suitable for indoor construction as well as many sheltered or moderate-exposure outdoor projects.

Choose Hot Dip Galvanized when you want the highest level of protection for continuously exposed structures, frequent moisture or demanding industrial environments. Its substantially heavier zinc coating generally provides a longer service life under harsh conditions.

Both versions use zinc to protect the underlying steel and both perform the same mechanical function. HDG is the heavy-duty upgrade; EG/ZP is not limited to indoor use.

Electro-Galvanizing or zinc plating uses an electrical process to apply a controlled layer of zinc to the steel. It produces a smooth, bright and relatively uniform surface with excellent general-purpose corrosion resistance.

Hot Dip Galvanizing immerses the steel in molten zinc. This creates bonded zinc-alloy layers and a much heavier outer coating, providing additional protection for demanding outdoor and industrial applications.

The finishing process affects coating thickness, appearance and long-term corrosion protection. It does not change the plate’s dimensions, fit or intended mechanical function.

Yes. Zinc Plated fittings provide excellent general-purpose corrosion resistance and can be used for many outdoor projects, particularly in sheltered locations or environments without constant moisture and harsh exposure.

For structures that will remain fully exposed to rain, coastal air, frequent condensation or other demanding conditions, Hot Dip Galvanized offers a heavier coating and additional long-term protection.

No. Hot Dip Galvanized fittings can also be used indoors, especially in humid workshops, utility rooms or areas affected by condensation. Its main advantage is the heavier zinc coating rather than a restriction to any particular location.

For normal dry or protected installations, the Zinc Plated version already provides excellent corrosion resistance. HDG is the better choice when maximum coating durability and long-term protection are the priorities.
