Features Of Galvanised Steel Square Tube
  • Zinc Coating: The galvanization process involves coating the steel with a layer of zinc, which provides excellent protection against rust and corrosion.
  • Durability: This coating ensures the tube remains rust-free even when exposed to moisture, chemicals, and other harsh environmental conditions.
  • Structural Integrity: Galvanized steel square tubes maintain the inherent strength of steel, making them suitable for heavy-duty applications.
  • Long Lifespan: The combination of steel’s strength and the zinc coating’s protective qualities results in a long-lasting product.
  • Wide Range of Sizes: Available in various sizes, wall thicknesses, and lengths to suit different applications.
  • Customizable: Can be customized to meet specific project requirements, including cut-to-length services and tailored dimensions.
  • Weldability: Galvanized steel square tubes can be easily welded, cut, and shaped, allowing for flexible fabrication options.
  • Workability: They are easy to work with using standard tools and techniques, facilitating various construction and manufacturing processes.
  • Durable Coating: The zinc coating requires minimal maintenance, reducing the need for frequent repairs or replacements.
  • Cost-Effective: The reduced maintenance needs translate to lower long-term costs, making it a cost-effective choice for many applications.
Applications Of Galvanised Steel Square Tube

Due to its strength, durability, and corrosion resistance, galvanized steel square tubes mainly used for construction and building infrastructure, fencing and handrails, outdoor furniture, automotive applications, utility and support structures, water and gas transportation, ect.
