Full Introduction to Structural Steel Pipe

Structural steel pipes are specialized steel components engineered for load-bearing structural applications, highlighted by stable bearing capacity, wide environmental adaptability and extended service life.

Hebei Hengtong Pipe Fitting Group is an original professional manufacturer of structural steel pipes. We carry out full-process quality control in strict compliance with international manufacturing standards to ensure every batch meets regional engineering acceptance criteria worldwide. Supported by consistent stable quality, our structural steel pipes are exported to numerous countries and regions, earning long-term trust from overseas engineering purchasers.

To accommodate diversified engineering environments and complex global climate conditions, we have established a complete material selection system. Every steel grade undergoes strict chemical composition inspection and mechanical performance testing to meet international specifications, and full material certification documents are delivered together with shipments to facilitate seamless one-stop customs clearance.

Ordinary carbon structural steel (Q235B)

With moderate carbon content, it boasts great plasticity, toughness and weldability, featuring a minimum yield strength of 235MPa and tensile strength between 400–550MPa. Cost-efficient and versatile, it is widely used in civil buildings, industrial workshops, construction scaffolding and warehouse storage racks.

Low-alloy high-strength structural steel

Compared with Q235B, manganese, vanadium and other alloy elements are added. It achieves yield strength above 355MPa and tensile strength of 510–600MPa, with significantly improved anti-corrosion and anti-fatigue performance, making it the top choice for large infrastructure projects.

Alloy structural steel (42CrMo, 15CrMoG)

Customized for extreme working scenarios, it reaches yield strength ≥690MPa and tensile strength ≥1080MPa. It possesses outstanding hardness, wear resistance and high-temperature stability, maintaining intact structural performance under high pressure, high heat and corrosive surroundings. Main applications include petrochemical pipe supports, wind turbine tower frames, deep-sea engineering structures and other high-standard special fields.

Reliable load capacity, convenient field assembly and long-term durability are the core design advantages of our structural steel pipes, detailed as below:

Premium raw materials paired with precision welding enable the pipes to withstand heavy static and impact loads without deformation or cracking, satisfying load-bearing demands of large key engineering projects.

Optimized material formulas and mature welding techniques ensure high weld joint strength, removing the need for complex secondary processing and allowing direct on-site assembly.

Custom anti-corrosion surface treatments are available for long-term stable operation in humid, high-temperature and corrosive outdoor surroundings, greatly reducing later maintenance costs.

Pipe outer diameters, wall thicknesses and lengths can be customized per project drawings to cut material waste and control overall procurement budgets.
