Square Galvanized Steel Tube

Square Galvanized Steel Tube is a steel tube that has been treated with a special coating process to prevent corrosion and extend its service life. The coating is usually made of zinc and applied through a process called hot-dip galvanizing. These tubes are often used in plumbing, building, and structural applications. The most common shapes we produce are galvanized round tubes and galvanized square tubes, in addition to galvanized rectangular steel tubes and oval galvanized tubes, as well as other irregular shapes to meet your project requirements.

• Protecting against corrosion and rust
• Increasing structural life
• Overall enhanced reliability
• Affordable protection
• Easy to inspect
• Reduces repairs
• Strong and durable
• Easier to maintain than standard painted pipes
• Protected by advanced ASTM standards

Square Galvanized Steel Tube can be cut, machined, or welded using methods commonly used for regular steel pipe. The sawn ends of our pre-cut lengths are not galvanized and should be treated with a cold galvanizing compound to maintain protection once the project is complete. Any drilled or welded areas should also be treated. The ends of the tubes in sizes 8" to 12" can be treated with a 3/4" hole in the dipping process. All sizes are before the galvanizing process. All sizes are plain end and unthreaded.

• Galvanized Coating Protection: Square Galvanized Steel Tubes undergo hot-dip galvanizing or electro-galvanizing processes to form a dense zinc layer on the steel tube surface, effectively isolating oxygen and moisture, preventing rust, and extending service life.
• Harsh Environment Adaptability: Suitable for high humidity, coastal areas, or industrial pollution environments, offering greater resistance to chemical corrosion than ordinary carbon steel tubes.
• Structural Stability: The square cross-section design provides higher bending and torsional strength, making it suitable for load-bearing structures (such as building frames and shelving).
• Weight Advantage: Compared to solid steel, the hollow structure reduces weight, facilitating transportation and installation while lowering overall costs.
