Product Detail

The cross-section of a hot-rolled H-beam consists of a web and two flanges (the vertical center portion is the web, and the two horizontal portions are the flanges). The inner and outer surfaces of the flanges are parallel, and their curved sections connect with the web. This structure has the following advantages:

High bending strength: The larger section modulus allows traditional I-beams and channel steels to withstand greater loads for the same weight.

Good structural stability: The constant flange width provides excellent lateral stiffness, making it suitable for bidirectional loads.

High material strength: Reduces stress concentration within typical steel sections, thus saving 10% to 30% of steel usage.

Surface Finish

Ordinary Surface

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

Black Oil Surface

Main Application

Construction: Primary beams and columns for high-rise buildings, warehouses, industrial plants, commercial and residential buildings.

Bridges & Infrastructure: Supporting systems for highway bridges, railway bridges, and viaducts.

Industrial Support: Machinery and equipment bases, crane beams, and building frames.

Ships and Offshore Platforms: Ship deck framing and offshore platform construction (requiring corrosion protection).

General Structural Use: Shelf supports, shoring for construction, jigs and fixtures.

Advantages: Cost effective, good weldability, medium bearing strength, applicable to large structural work.

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

Basic Protection: Each bale is wrapped with tarpaulin, 2-3 desiccant packs are put in each bale, then bale is covered with heat sealed waterproof cloth.

Bundling: The strapping is 12-16mm Φ steel strap, 2-3 tons / bundle for lifting equipment in American port.

Conformance Labeling: Bilingual labels (English + Spanish) are applied with a clear indication of material, spec, HS code, batch and test report number.

For large size h-section steel cross-section height ≥ 800mm), the steel surface is coated with industrial anti-rust oil and dried, then packed with tarpaulin.

Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.

We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling.
