Tianjin Brisk Steel is one of the manufacturers of Hot Finished structural hollow sections (HFCHS) in China. Our products are mainly exported to the Middle East, Southeast Asia, Europe, New Zealand, and other regions.If you would like to learn more about our products, feel free to contact us and send your purchase list.
Products Description
HFCHS is widely available in common grades including S235JRH, S275J0H, S275J2H, S355J0H, S355J2H and S355NH. It supports heavy-wall and large-size specifications that cannot be fully covered by cold-formed products, making it the preferred solution for heavy-load and structurally critical applications.
Typical applications
Include building structural columns, steel trusses, bridge structures, stadium frameworks, offshore auxiliary structures, mechanical equipment frames and anti-seismic construction projects. Due to its reliable performance in low-temperature and high-stress working conditions, HFCHS is highly recognised in European, Middle Eastern, Southeast Asian and global engineering markets.
Key advantages
• Low residual stress for stable structural performance
• Excellent low-temperature toughness for harsh environments
• Uniform section property and reliable weldability
• Full EN 10210 standard compliance with complete inspection certificates
• Custom sizes and steel grades available for engineering projects

Frequently Asked Questions (FAQ)
Q: Can you supply heavy-wall and large-size HFCHS sections?
A: Absolutely. One of the biggest advantages of hot finished hollow sections is the capability for heavy-wall and large-diameter/size production, which cannot be achieved by conventional cold-formed hollow sections. We support customized large-size and thick-wall specifications for heavy structural engineering.
Q: Is HFCHS suitable for outdoor, offshore and low-temperature environments?
A: Yes. Thanks to high-temperature heat treatment, HFCHS has stable mechanical properties, excellent weldability and superior low-temperature toughness. It is widely used for outdoor steel structures, stadium frameworks, bridge components, offshore auxiliary structures and construction projects in cold regions with strict anti-seismic and durability requirements.
Q: Can we get customized sizes and lengths for HFCHS?
A: Yes. We offer customized processing services including custom cutting lengths, special dimension tolerance control, surface treatment and tailored grade solutions to fit different architectural and structural engineering needs.
Q: Are your HFCHS products fully certified for European construction project
A: Yes. All our HFCHS strictly comply with EN 10210-1 and EN 10210-2 standards. We can provide complete official documents including factory test certificates (3.1 / 3.2), dimension inspection reports, chemical composition and mechanical property test reports, meeting EU construction market entry requirements.
