What Is Hollow Section Steel Tube: Core 2026 Definition

Hollow Section Steel Tube is a hollow closed-profile steel product with square, rectangular or round cross-sections for structural use. In practice, over 68% of modern low-rise and high-rise construction projects use hollow section steel tubes as core load-bearing components, per 2026 World Steel Association industry data. Unlike solid steel bars, its hollow design cuts unnecessary material waste while retaining excellent torsional and bending strength for long-term structural stability.

1. 30% higher torsional strength than same-weight solid steel bars
2. 15% lighter overall weight to reduce on-site installation labor cost
3. Lower outer surface area to cut anti-corrosion coating expenses by 22%

Step-by-Step Guide to Select Qualified Hollow Section Steel Tube

In practical procurement work, following the 3 core steps below can help you avoid 90% of common quality traps effectively:

1. Confirm project load-bearing requirement first, select matching wall thickness and yield strength grade to avoid over-spec or under-spec procurement
2. Verify third-party material test report from the manufacturer before shipment, check chemical composition and mechanical performance data
3. Conduct appearance inspection on received goods, reject products with uneven wall thickness, surface cracks or incomplete anti-corrosion coating

Q3: Can Hollow Section Steel Tube be used directly for coastal construction projects?

Plain carbon steel hollow section tubes are not suitable for coastal areas, you need to choose aluminum-zinc coated grades with 1000+ hour salt spray resistance to reach 30+ years service life.

Q4: What is the price range of Hollow Section Steel Tube in 2026?

2026 average wholesale price ranges from $580 to $920 per ton, depending on material grade, wall thickness, surface treatment and total order quantity.
