Hot-Dip Galvanized Square Pipe: The surface is treated with a hot-dip plated or galvanized layer. This process significantly increases corrosion resistance and prolongs the service life of the steel pipes. These tubes are widely utilized beyond standard fluid pipelines for gas, water, and oil; they are critical in the oil industry, offshore oil wells, bridge piling, and mine tunnel support frames.
The galvanized square tube features an alloy layer produced by the reaction of molten metal with the iron matrix, ensuring a strong bond between the substrate and the plating. It offers advantages such as a uniform coating, strong adhesion, and long-term durability compared to traditional non-galvanized pipes.
