High Building Structure Pipe

High Building Structure Pipe

Brief Version

High Building Structure Pipe is JCOE LSAW load-bearing steel pipe manufactured by Hebei Hengtong Pipe Fitting Group, specially designed for high-rise building frame, shear wall and tube structural systems. It meets strict standards for high strength, seismic & wind resistance and lightweight design, serving as core support columns and beams for tall buildings.

We supply complete customizable specifications from OD 457mm to 1422mm, WT 8mm–500mm, with multiple steel grades including Q235, Q345 and high-strength alloy steel complying with API 5L, ASTM A252 and EN standards. Our fully automatic submerged arc welding process guarantees high weld quality and stable mechanical performance, supporting large-scale construction, bridge piling and municipal engineering projects with balanced safety and construction efficiency.

Detailed Version

Product Overview

High Building Structure Pipe is dedicated tubular material for high-rise building construction. Four mainstream high-rise structural systems adopt our pipe products: frame structure, shear wall structure, frame-shear wall structure and tube structure.

As core load-bearing components, high-rise structural pipes possess ultra-high standards on strength, structural stability, wind resistance, earthquake resistance and lightweight performance. They are widely applied as frame columns, shear wall supports and other key bearing parts, simultaneously satisfying load-bearing safety and fast on-site construction efficiency.

Produced via mature JCOE LSAW submerged arc welding technology by Hebei Hengtong Pipe Fitting Group, this product also fits steel structure workshops, bridge foundation piling, municipal infrastructure, long-distance water & gas transmission and urban construction projects.

Material Classification & Application Scenarios

Non-alloy structural steel

Minimum yield strength ≥235MPa, outstanding ductility, easy welding and cost advantage. Suitable for supporting components of low-rise and common high-rise buildings.

Fine-grain structural steel

Minimum yield strength ≥355MPa, balanced strength and low-temperature toughness, impact energy ≥34J at -20℃/-40℃. Ideal for frame beams and columns of mid-rise and high-rise buildings.

High-strength structural steel

Minimum yield strength ≥420/460MPa, superior tensile strength and anti-fatigue performance, designed for core load-bearing structures of skyscrapers over 100 meters high.

Stainless steel pipe

Excellent corrosion resistance, yield strength ≥205MPa, available grades 304 / 316L. Mainly used for special coastal high-rise projects under heavy salt spray environment.

All high-rise structural pipes pass strict standard inspections, as their performance directly relates to property and personal safety of building occupants. Qualified pipes maintain long-term stable bearing performance under wind load, seismic impact and long-term static pressure.
