This 2026 practical guide covers full definition, production workflow, performance grading, common applications and cost-saving purchasing tips for Hollow Section Steel Tube, based on Henghui Steel’s over 1.2 million tons of manufacturing experience, helping global buyers select qualified products and cut total project structural cost by up to 27%.
📋 Article Overview
This SEO optimized guide is tailored for construction contractors, project managers and steel wholesalers searching for verified information about Hollow Section Steel Tube, integrating 2026 latest industry data and first-hand factory test results.
What Is Hollow Section Steel Tube: Official 2026 Definition
Hollow Section Steel Tube is a hollow structural steel profile with square, rectangular or round cross-section for load-bearing applications. In practice, Henghui Steel has produced more than 1.2 million tons of such products since 2002, strictly following ASTM A500, EN 10219 and JIS G3466 international standards to meet different regional project requirements.
Q: What are the 3 core categories of Hollow Section Steel Tube?
A: They are classified as Square Hollow Section (SHS), Rectangular Hollow Section (RHS) and Circular Hollow Section (CHS), each designed for different load distribution scenarios. Actual test shows that SHS products have 18% higher torsional resistance than same-weight CHS products.
Q: Why is Hollow Section Steel Tube more popular than solid steel bars in 2026?
A: It reduces total raw material weight by 30% to 40% while maintaining equal or even higher bending strength, cutting transportation and installation cost significantly for mid to large scale projects.
Standard Manufacturing Workflow of Hollow Section Steel Tube
From Henghui Steel’s 21-year production cases, standardized production process eliminates over 92% of hidden quality risks including weld crack, dimensional deviation and unqualified yield strength. The verified full workflow is listed below:
- Raw material incoming inspection: All hot rolled steel coils pass 3 layers of spectral composition test to confirm no impurity over limit
- Cold forming or hot extrusion process to shape the target cross section with tolerance controlled under ±0.2mm
- Automatic high-frequency welding and weld seam grinding, followed by 100% non-destructive eddy current flaw detection
- Stress relieving annealing treatment to eliminate internal stress, avoiding deformation after long term outdoor use
- Customized surface treatment (hot galvanization, powder coating, anti-rust oil) and precision cutting to required lengths
- Final dimensional check, surface inspection, marking and packaging for global shipment

Performance & Price Comparison of Common Hollow Section Steel Tube Grades
2026 latest industry test data shows different grades of Hollow Section Steel Tube fit distinct project scenarios, the core comparison data is listed in the table below:
| Comparison Dimension | Q235B Grade | Q355B Grade | S355JR Marine Grade |
|---|---|---|---|
| Minimum Yield Strength | 235 MPa | 355 MPa | 355 MPa |
| Corrosion Resistance (Outdoor Use) | 10-15 years | 15-20 years | 25-30 years |
| Unit Weight (100*100*5mm Spec) | 14.8 kg/m | 14.9 kg/m | 15.0 kg/m |
| Price Premium (vs Q235B) | 0% | +12% | +22% |
| Typical Application | Low-rise building frames | Heavy load bridges | Offshore platforms |
The 2026 global steel structure industry consensus shows that using qualified Hollow Section Steel Tube can reduce total structural steel consumption by an average of 27% compared with traditional I-beam systems for low-rise to mid-rise commercial buildings.
