Product Detail

Hot-rolled H-beam feature a cross-section composed of one web and two flanges. The vertical central section serves as the web, while the two horizontal segments are flanges. Flange inner and outer surfaces run parallel, with curved transitions linking the flanges to the web.

This design delivers distinct structural benefits:

Superior bending resistance: Thanks to a higher section modulus, H-beams bear heavier loads than conventional I-beams and channel steel at equivalent weight.

Reliable structural stability: Uniform flange width delivers strong lateral stiffness, performing well under two-way loading conditions.

Efficient material utilization: This profile minimizes internal stress concentration, cutting steel consumption by 10%–30%.

Surface Finish

Ordinary Surface

Galvanized Surface (hot-dip galvanizing thickness ≥ 85μm, service life up to 15-20 years),

Black Oil Surface

Main Application

Building Construction

Main beams and columns for high-rise structures, warehouses, manufacturing facilities, commercial and residential developments.

Bridge & Infrastructure Projects

Support frameworks for highway bridges, railway bridges and viaducts.

Industrial Structural Supports

Equipment foundations, crane girders and factory building frames.

Marine & Offshore Engineering

Deck framing for vessels and offshore platform structures; anti-corrosion surface treatment is required for such scenarios.

General Structural Applications

Rack supports, temporary construction shoring, custom jigs and mounting fixtures.

Core Benefits

Economical with reliable weld performance and moderate load-bearing capacity, well suited for large-scale structural engineering projects.

Royal Steel Group Advantage（Why Royal Group Stands Out for Americas Clients?）

1) Branch Office - Spanish-speaking support, customs clearance assistance, etc.

2) Over 5,000 tons of stock in stock, with a wide variety of sizes

3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging

Packing And Delivery

Standard Protection
Every bundle is wrapped with tarpaulin. 2 to 3 desiccant sachets are placed inside each package, followed by a heat-sealed waterproof outer cover.

Bundling Specifications
We use 12–16 mm diameter steel strapping. Each bundle weighs 2–3 tons, compatible with lifting equipment at US ports.

Marking & Labels
Dual-language labels (English / Spanish) are attached. Labels clearly mark material grade, dimensions, HS code, batch number and test report reference.

Oversized H-Beam Packing (Section height ≥ 800 mm)
Large H-section steel receives an industrial anti-rust oil coating and air-drying treatment. Products are then fully wrapped with tarpaulin.

We maintain long-term partnerships with major carriers including MSK, MSC and COSCO to deliver efficient, reliable logistics solutions tailored to satisfy your requirements.

All operations comply with the ISO 9001 quality management system. We enforce rigorous controls covering every step, from sourcing packing materials to scheduling transport vehicles. This ensures our H-beams arrive intact from our factory directly to your job site, laying a reliable groundwork for smooth project execution.
