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
Comprehensive Protection & Packaging: Each bundle of I-beams is carefully wrapped in tarpaulin, with 2–3 desiccant packs included per bundle, and secured under a heat-sealed, rainproof covering to prevent moisture damage.
Secure Bundling: Bundles are strapped with 12–16 mm Φ steel bands, designed to handle lifting equipment at American ports, supporting 2–3 tons per bundle safely.
Clear Compliance Labeling: Bilingual (English & Spanish) labels are attached to every bundle, providing essential information such as material grade, specifications, HS code, batch number, and test report reference.
Special Handling for Oversized Sections: For I-beams with a cross-sectional height of ≥ 800 mm, the steel surface is coated with industrial-grade anti-rust oil, allowed to dry, and then wrapped in tarpaulin for extra protection.
Efficient Logistics Network: We maintain strong partnerships with leading shipping lines, including MSK, MSC, and COSCO, ensuring reliable and timely transportation.
Quality Assurance: Our operations strictly follow ISO 9001 quality management standards. From packaging material selection to transport allocation, every step is closely monitored to ensure that I-beams arrive in perfect condition, providing a solid foundation for smooth and efficient project execution.
