Galvanized square tubing refers to square-shaped metal tubes that have been coated with a layer of zinc through a process called galvanization. Galvanization involves immersing the steel tubing in a bath of molten zinc, which creates a protective layer that helps prevent rust and corrosion.

The galvanization process provides several benefits to square tubing. The zinc coating acts as a barrier between the steel and the environment, protecting the underlying metal from exposure to moisture, oxygen, and other corrosive elements. This makes galvanized square tubing particularly suitable for outdoor or exposed applications where rust resistance is essential.

Galvanized square tubing is commonly used in various industries and applications, including construction, agricultural equipment, fencing, handrails, the framework for trailers, and general fabrication. The square shape of the tubing offers structural stability and allows for efficient connections and joins.
