Various concrete structures required in the civil engineering field are pre-fabricated at the factory rather than on the site, and are provided to the site in the best condition according to the construction situation. Compared to the cast-in-place method, you can expect effects such as shortening the construction period, reducing the construction cost, and securing the quality of the structure.
The concrete segment for shield construction is producing high-quality products with high precision and quality, and we are recognized for its excellence by supplying it to construction sites in Seoul subway construction, railway facility construction, Korea Electric Power Corporation, and Tokyo Electric Power Corporation.
Concrete sleepers are manufactured by the pre-stress method. In accordance with the Railroad Safety Act set by the Ministry of Land, Infrastructure and Transport, we have obtained type approval and manufacturer approval to deliver uniform products to the site through thorough quality control and advanced technology in factories with automated facilities.
As a cast-in-place method, The Bi-Block sleeper used for the concrete track of the railway track is a continuous reinforced concrete structure that integrates the sleeper and the track concrete by binding the lattice girder and the track reinforcing bars of the Bi-Block sleeper, and has the advantages of excellent durability and simple installation.
The PST system is a supplementary system to ensure uniform quality of the concrete track that is being cast on site. It can shorten the construction period and reduce costs by assembling the manufactured panels on site and integrating them through the lower mortar filling.
