I-beams, as a crucial steel material for building and industrial structures, require careful packaging and transportation to ensure product quality and safety. Proper packaging and transportation not only prevent surface damage but also improve logistics efficiency and reduce transportation risks.
I. Packaging Methods
Strapping Packaging:
Use steel straps or nylon straps to bundle the I-beams according to specifications and lengths for easy loading, unloading, and handling.
Wooden Pallets/Dummy Boards:
Place wooden pallets or dummies under the bundled I-beams to prevent direct contact with the ground, thus preventing scratches or moisture corrosion.
Protective Measures:
Add corner protectors or plastic protective sleeves to vulnerable areas (such as edges and end faces);
Use waterproof film or plastic film to cover the steel to prevent rain and moisture from causing rust.
II. Transportation Methods
Land Transportation:
Suitable for short-distance or domestic transportation, generally using flatbed trucks or low-sided vehicles.
Ensure secure bundling to prevent slipping or tipping during transportation.
Rail Transport:
Suitable for long-distance, large-volume transport; strong load-bearing capacity and high transport stability.
Must be loaded according to rail transport specifications, securely fixed, and equipped with protective dunnage.
Sea Transport:
Used for export or cross-border transport; can be transported via container or bulk carriers.
H-beams typically need to be bundled, covered with waterproof tarpaulins, and secured inside the ship's hold to prevent displacement.
III. Precautions
Avoid impacts or friction during loading and unloading to prevent damage to the steel surface;
For long-distance transport, regularly inspect the bundling straps and securing devices to ensure transport safety;
For H-beams transported in special environments (such as coastal areas or humid regions), strengthen rust prevention measures.
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 H-beams from the factory all the way to the project site, helping you build on a solid foundation for a trouble free project!
Q: What standards do your H beam steel comply with for Central American markets?
A: Our products meet ASTM A36, A572 Grade 50 standards, which are widely accepted in Central America. We can also provide products compliant with local standards such as Mexico's NOM.
Q: How long is the delivery time to Panama?
