Packaging
Basic protection: Each bundle of steel is wrapped with a tarpaulin on the outside, and 2 to 3 packages of desiccant are placed inside. The outer layer is fully wrapped with heat-sealed waterproof fabric to prevent moisture.
Binding method: Use Φ12–16mm steel wire to reinforce the bundle, which is compatible with the lifting equipment at American ports. The weight of each bundle is controlled at 2–3 tons.
Identification labels: Attach bilingual English-Spanish labels, indicating the material, specification, HS code, batch number and inspection report number. Quality inspection documents are attached along with the goods.
Delivery and Transportation
Road transportation: For short-distance delivery or when the vehicle can directly reach the construction site, the goods are loaded with anti-slip fixing accessories.
Railway transportation: Suitable for long-distance and large-scale cargo transportation. Compared to road transportation, it can save transportation costs.
Sea transportation: Ordinary goods can take standard containers; for extra-long profiles, they can be transported using bulk or open-top containers.
Inland river barge transportation: Extra-large H-shaped steel can be transported in an unboxed manner on inland waterways.
Special transportation: H-shaped steel with dimensions and weight exceeding the conventional transportation limits is transported by multi-axle low flatbed trailers or combined trailers.
Shipping Plan for the American Market
ASTM H-shaped steel sold to the Americas is packed in batches, with steel straps for tightening and end protection reinforcement; rust prevention treatment can be done as needed to avoid rusting during sea transportation.
Q1: What standards do the wide-flange steel beams follow?
Answer: The W-shaped steel beams we produce will be generated in accordance with international standards, such as those conforming to ASTM A6/A6M and others.
Q2: What are the common specifications of W-shaped steel beams?
Answer: Among them, W12×26 and W14×34 are widely used in construction projects. In addition, there are also W8, W10, W12, W14, W16, W18, W21 series and other mainstream models.
Q3: Can the length be customized?
Answer: Yes. The regular lengths are 6 meters, 9 meters, and 12 meters. We support on-demand cutting to the required lengths.
Q4: Do you have any quality inspection certificates for your products?
Answer: Yes, we do. And we can accept third-party inspections.
