Full Protection: the I-beams are wrapped with tarpaulin and 2–3 packets of desiccant; the heat-sealing, water proof tarpaulin sheets block the rain from invading in the I-beams.
Bundling security: each bundle is wrapped with 12 - 16 mm steel straps; suitable for 2-3 tons and has us compatible lifting equipment.
Transparent labelling: Bilingual labels (in English and Spanish) with grade, specifications, HS code, batch # and a reference to the test.
Protection High Profile: I beams ≥800 mm were coated with an alignment oil once and covered with a tarpaulin two times.
Delivery
Dependable Shipping: Best carriers' Cooperation( MSK, MSC, COSCO ect) to ensure Safe sailing.
Quality Control: ISO 9001 system; The beams are dust-tight, and you can be confident they will arrive intact which means you will have a trouble free project.
