Explore Our Section Steel Series

Section steel is the fundamental building block of the construction and engineering industries. Manufactured through high-temperature hot rolling, these profiled steel members offer exceptional load-bearing capacity, bending resistance, and structural stability.

At Luyuan Steel, we provide a complete suite of structural steel products to support your projects from the foundation up. Our portfolio includes heavy-duty H-beams for primary frameworks, versatile L and C beams for secondary supports, interlocking sheet piles for earth retention, and seismic-grade deformed rebar for concrete reinforcement. All materials are rigorously tested to meet international building codes.

Why Source Structural Steel from Luyuan?

High-Strength & Seismic Grades

Safety is non-negotiable in construction. We supply high-yield structural steel (like S355JR and Q345B) and seismic-grade deformed rebar (HRB400E/HRB500E) designed to absorb massive energy and prevent sudden structural failure during earthquakes.
Massive Production Capacity

Large infrastructure projects require reliable, bulk material delivery. With our robust supply chain and extensive inventory of H-beams and rebar, we guarantee stable, on-time shipments to keep your construction schedule on track, regardless of project scale.
Hot-Dip Galvanizing Services

For structural steel exposed to the elements or harsh industrial environments, we offer premium hot-dip galvanizing services. This thick zinc coating provides decades of maintenance-free corrosion protection for your beams and angles.
Precision Cut-to-Length

Minimize on-site labor and material waste. We provide precision sawing and cutting services for all our section steel products, delivering beams and rebar in the exact lengths required by your engineering blueprints.
Full Certification & Traceability

Every piece of structural steel we export is fully traceable. We provide comprehensive Mill Test Certificates (MTC) detailing chemical composition and mechanical yield strengths, ensuring compliance with local building authorities and engineering standards.

Custom Processing for Structural Steel

We deliver section steel ready for immediate erection and assembly. Our processing center offers:

Cutting & Sawing	Precision cutting of H-beams and channels to specific lengths with exact tolerances
Drilling & Punching	Pre-drilling bolt holes in beam flanges and webs according to CAD drawings
Welding & Fabrication	Welding base plates, stiffeners, or cleats to structural columns
Surface Protection	Shot blasting (SA 2.5) and applying anti-rust primer or hot-dip galvanizing
Rebar Processing	Bending, cutting, and threading of steel rebar for immediate concrete placement

Send us your structural drawings, and our engineering team will provide a fully fabricated solution.

Applications of Section Steel

Frequently Asked Questions

What is the difference between H Beam and I Beam?

While both are structural beams, an H Beam has wider flanges that are parallel (not tapered), making its cross-section look like the letter “H”. This design gives H Beams a significantly higher strength-to-weight ratio and better resistance to twisting, making them the standard choice for heavy load-bearing columns and long spans.
What does the "E" mean in HRB400E rebar?

The “E” stands for Earthquake (Seismic) resistance. HRB400E rebar is manufactured with specific chemical and mechanical properties that give it higher ductility. This allows the concrete structure to flex and absorb energy during an earthquake without the steel snapping suddenly.
Do you provide anti-rust treatments for structural steel?

Yes. Standard section steel is supplied “black” (bare metal). For corrosion protection, we offer shot blasting followed by shop primer painting, or Hot-Dip Galvanizing, which provides the ultimate long-term protection for outdoor or marine environments.
