Sumitomo (SEI) Steel Wire Corp., a subsidiary of Sumitomo Electric Industries, Ltd., has delivered polyethylene-coated inner-filled-type epoxy-resin-coated prestressed steel strands (PE-coated ECF strands) to Hai Phong City, Vietnam for the construction of the access road and bridge to the Lach Huyen International Port including bridges.

The Government of Vietnam is currently pushing ahead with the Lach Huyen International Port construction project. The access road and bridges to the port are being built by a joint venture between Sumitomo Mitsui Construction Co., Ltd. and a local construction company. PE-coated ECF strands that Sumitomo (SEI) Steel Wire developed and manufactured had been chosen for use in the bridges, and approximately 1,200 tons of the strands were delivered to the construction site in December 2016. The Lach Huyen Bridge exceeds 5.4 km, becoming the longest offshore bridge in Vietnam. In Japan, PE-coated ECF strands have been used extensively mainly as outer cables for bridges; the construction of the Lach Huyen Bridge is the first overseas case in which they are used on a large scale.

The PE-coated ECF strand is characterized by high corrosion-resistance and robustness provided by a double coating composed of polyethylene (PE) and epoxy resins. Eliminating the need for connecting polyethylene tubes and pouring grout* on the site, the new products have significantly shortens construction time and labor costs. This bridge, furthermore, uses 19-wire 28.6 mm-diameter PC strands as transverse steel members.

The bridge is scheduled to be completed in May 2017 and expected to greatly contribute to the economic development of Vietnam as a major transport artery of physical distribution.
