Why Built-Up Steel Sections Dominate Modern Construction

Built-up sections in steel let you control dimensions like a master sculptor. Need a 20-meter clear span? Customize flange thickness. Battling seismic zones? Reinforce web plates. Unlike rigid steel hollow sections, built-up designs adapt to your exact stress calculations.

Steel Hollow Sections vs. Built-Up: Which Wins Your Wallet?

Our rectangular hollow section steel shines in modular projects—think 30% faster bolt-up times. But for mega-stadiums? Built-up sections cut welding hours by 40%. See how top contractors choose:

• ✅ Built-up: High-rise cores, bridge trusses
• ✅ Hollow sections: Roof lattices, conveyor frames

Your Project, Your Rules: Precision-Built Steel Solutions

We laser-cut your specs into reality. Last month, a Dubai client needed built-up sections in steel with 120mm flange widths for a wind farm. Our CNC plasma system delivered 0.2mm precision—3 days ahead of schedule.

Case Study: Airport Roof Revamp with 40% Cost Savings

Denver International replaced solid beams with our rectangular hollow section steel. Result? $2.1M saved through 28% lighter structures. The secret? Our proprietary anti-corrosion coating extends lifespan to 75+ years.

FAQS on built up section in steel

Q: What is a built-up section in steel?

A: A built-up section in steel is a structural component created by combining multiple steel plates or shapes (e.g., angles, channels) through welding or bolting. It is used when standard rolled sections cannot meet design requirements for strength, stiffness, or size.

Q: How does a built-up steel section differ from a steel hollow section?

A: Built-up sections are fabricated by assembling individual steel plates or profiles, offering customization, while steel hollow sections (e.g., RHS) are pre-formed into closed tubular shapes during manufacturing. Hollow sections excel in torsional resistance and aesthetics compared to built-up sections.

Q: When should I use a built-up steel section instead of a rectangular hollow section?

A: Built-up sections are preferred for heavy-load applications requiring unique geometries or enhanced load-bearing capacity. Rectangular hollow sections (RHS) are better for lightweight structures needing high torsional strength and a clean appearance.

Q: What are the advantages of steel hollow sections?

A: Steel hollow sections provide excellent strength-to-weight ratios, resistance to twisting, and streamlined aesthetics. They also simplify construction due to their uniformity and ease of welding or bolting.

Q: Are rectangular hollow section steel members suitable for seismic zones?

A: Yes, rectangular hollow sections (RHS) perform well in seismic regions due to their high torsional rigidity and energy absorption capabilities. Proper design and connections ensure compliance with seismic codes.
