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. This guarantees the I-beams from the factory all the way to the project site, helping you build on a solid foundation for a trouble free project!
