High-Performance Hollow Sections for Structural, Industrial and Infrastructure Applications

Galvanized Square Tubes and Rectangular Steel Tubes are cold-formed hollow structural sections designed for projects that demand durability, precision, and corrosion resistance. Manufactured from premium-grade carbon steel and finished with a protective zinc coating, these products offer dependable performance in both structural and non-structural applications.​
Available in a wide selection of dimensions and wall thicknesses, galvanized hollow sections combine lightweight construction with high mechanical strength, making them a preferred solution for architects, engineers, contractors, and equipment manufacturers.​
Whether used in steel buildings, renewable energy systems, transportation facilities, or agricultural projects, galvanized tubing provides a balance of structural efficiency and long-term value.

Unlike ordinary steel tubing, galvanized hollow sections are engineered to perform in environments where corrosion resistance is essential.​

Precision Manufacturing

Each tube is produced using roll-forming and high-frequency welding technology to achieve accurate dimensions, straightness, and consistent wall thickness.​

Superior Surface Protection

The zinc coating forms a continuous protective layer that minimizes oxidation and improves resistance to weathering.​

Reliable Structural Performance

Square and rectangular profiles provide excellent rigidity while maintaining a favorable strength-to-weight ratio, allowing designers to reduce structural weight without sacrificing performance.​

Fabrication Friendly

The material is suitable for cutting, drilling, punching, bending, and welding, making it easy to integrate into customized fabrication projects.​

Extended Service Life

The zinc coating significantly slows the corrosion process, allowing structures to remain in service for many years with minimal maintenance.

Lower Maintenance Costs

Unlike painted steel, galvanized tubing requires less frequent surface treatment, reducing maintenance expenses over the lifetime of the project.

Improved Structural Efficiency

Hollow sections provide high bending resistance while reducing overall structural weight, helping optimize material usage.

Sustainable Construction Material

Galvanized steel is fully recyclable and supports environmentally responsible construction practices.

Galvanized square and rectangular tubes are suitable for a wide variety of engineering applications.

The durability of galvanized tubing is achieved through two complementary protection mechanisms.

Zinc Barrier Layer

The galvanized coating prevents direct contact between the steel surface and corrosive elements such as water and oxygen.

Self-Sacrificing Protection

If scratches occur during installation or service, the surrounding zinc continues protecting the exposed steel by corroding before the steel substrate.

This electrochemical process greatly improves the service life of galvanized hollow sections.

When selecting galvanized square or rectangular tubing, consider the following technical factors:

Structural Requirements

Determine the required section size and wall thickness according to design loads.

Exposure Environment

For coastal or chemically aggressive environments, select hot-dip galvanized tubing with higher zinc coating weights.

Fabrication Requirements

Confirm whether the project requires laser cutting, punching, bending, welding, or other secondary processing.

Applicable Standards

Choose products manufactured according to ASTM A500, EN 10219, JIS G3466, or customer-specified standards.

Every production batch undergoes strict quality inspections to ensure consistent performance.

Inspection items include:

• Dimensional accuracy
• Wall thickness tolerance
• Zinc coating quality
• Surface appearance
• Weld integrity
• Mechanical properties

This quality management process ensures every tube meets international engineering requirements.
