GCC USP
Key Advantage
Our commitment to excellence ensures that every hollow section we deliver combines superior metallurgical properties with precision fabrication to optimize your project's safety and efficiency.
- Extended Service Life: The hot-dipped galvanized finish creates a robust metallurgical bond that acts as a sacrificial anode. This ensures the steel remains protected from rust and oxidation for decades, even in coastal or high-humidity regions.
- High-Strength Steel Grades:We utilize premium materials ranging from Q195B to Q355B (S355JR). Our high-strength options allow for significant weight reduction in structures without compromising safety or load-bearing capacity.
- Ready-to-Assemble Customization:We streamline your construction timeline by providing in-house cutting, bending, and punching. Our sections arrive at your site pre-fabricated to your exact specifications, eliminating the need for on-site modifications.
- Uniform Precision:Our manufacturing process ensures consistent wall thickness and sharp, accurate corners for both square and rectangular profiles. This precision is vital for seamless welding and perfect alignment in modular frameworks.

FAQ's
Here are the answers to your questions
Are your galvanized hollow sections available in both square and rectangular shapes?
Yes. We supply a full range of sizes for both Square Hollow Sections (SHS) and Rectangular Hollow Sections (RHS). Both profiles share the same high-quality material grades and galvanization standards.
Can these sections be welded after galvanization?
While they can be welded, it is important to follow proper safety protocols and touch up the weld area with cold-galvanizing spray to maintain corrosion resistance. We also offer pre-welding fabrication before the galvanizing process for maximum protection.
What is the benefit of ASTM A500 Grade B for these sections?
ASTM A500 Grade B is a widely recognized standard that specifies higher minimum yield and tensile strengths, ensuring the pipe can handle the stresses of structural building applications.
How do you ensure the zinc coating is consistent?
We use a high-standard hot-dipped process that ensures the interior and exterior of the hollow section are fully coated, preventing “hidden” internal rust.
Can you provide custom punched holes for bolting?
Absolutely. Our precision punching and drilling services allow us to deliver sections with exact hole patterns, making them “ready-to-bolt” upon arrival at your project site.
