Application&Photos
Our PC strand is mainly used for the reinforcement of prestressed
concrete structures, such as large-span railway and road bridges,
major bridges, silos, buildings, dams, floor slabs, foundations,
large concrete vessels, atomic reactor buildings, stadiums, airport
hangers, pre-cast segments, crane beams, anchorages and
multi-storey industrial buildings etc.
Our PC strand is also used for the construction of highways, poles
and water towers in civil construction, and energy source sea
transportation, house buildings, water control projects, and rock
and earth anchoring components to increase the tensile force.
