Description
Galvanized Square & Rectangular Hollow Sections for Building Frames and Industrial Fabrication
Product Description

Galvanized Square Hollow Sections (SHS) and Rectangular Hollow Sections (RHS) are versatile structural steel products designed to deliver outstanding strength, corrosion resistance, and long-term reliability. Manufactured from premium carbon steel and coated with zinc through advanced galvanizing processes, these hollow sections are engineered for demanding indoor and outdoor applications.

Available in a broad range of dimensions and wall thicknesses, galvanized hollow sections combine excellent mechanical performance with superior weather resistance. Their clean appearance, easy fabrication, and low maintenance requirements make them one of the most popular steel products in modern construction and infrastructure projects.

Cause

Many structural projects operate in environments where steel is continuously exposed to rain, humidity, temperature fluctuations, industrial pollutants, and chemical contaminants.

Without adequate protection, ordinary carbon steel tubing can experience:

  • Rapid oxidation and rust formation
  • Reduced load-bearing performance
  • Surface deterioration and aesthetic damage
  • Frequent repair and repainting requirements
  • Increased lifetime operating costs

For engineers, contractors, and project owners, corrosion protection has become a critical factor when selecting structural steel materials.

Solution

Galvanized hollow sections offer a proven method of protecting steel against environmental degradation.

By applying a zinc coating to the surface of the steel tube, the material gains long-lasting resistance to corrosion while maintaining its structural integrity.

Key Advantages
  • Outstanding anti-corrosion performance
  • Excellent structural stability
  • Longer service life than untreated steel
  • Reduced maintenance expenses
  • Suitable for harsh outdoor environments
  • Strong resistance to moisture and oxidation
  • Cost-effective over the entire project lifecycle

This protective system enables steel structures to remain reliable even in coastal, industrial, and high-humidity environments.

FAQ
Q1: Why are galvanized hollow sections preferred over painted steel tubes?

Galvanized tubes provide integrated corrosion protection throughout the entire surface, while paint coatings can crack, peel, or require regular maintenance.

Q2: Are galvanized square tubes suitable for coastal projects?

Yes. Hot-dip galvanized square tubes perform exceptionally well in coastal and marine environments due to their thick zinc coating and sacrificial protection properties.

Q3: What is the difference between SHS and RHS?

SHS refers to Square Hollow Sections with equal side dimensions, while RHS refers to Rectangular Hollow Sections with unequal side dimensions.

Q4: Can galvanized rectangular tubes be fabricated after purchase?

Yes. They can be cut, drilled, bent, welded, and assembled according to project requirements.

Q5: What zinc coating thickness should I choose?

For indoor projects, lighter coatings may be sufficient. For outdoor, industrial, or marine environments, a zinc coating of 120–275 g/m² is generally recommended for enhanced durability.
