Packing And Delivery

Our I-Beams are securely packaged and protected for the transport: steel strapped, supported by wooden blocks and equipped with protective end caps. Anti-rust is done for ocean or long haul shipping. We provide versatile shipping services such as port to port, truck transport and project logistics. You can expect to receive your I Beam from stock within 7-15 days, customized sizes are also welcomed. For the American market, a ASTM I-Beam is generally shipped by container with steel strapping, end protection and anti-rust coating for secure and clean delivery.
