Prestressed concrete uses much less materials than reinforced concrete: savings can reach 40% of the overall mass Longer spans, thinner and lighter parts allow a reduction in number of piles, height of buildings, consumption of energy in freight and handling, therefore CO2 emissions.
Low relaxation ensures that no noticeable loss of tension will occur in time, therefore a long lasting compressive force on concrete.
Deviated tension is current in post-tensioned structures, stay-cables and even some prefabrication methods. By strict adherence to manufacturing processes and routine destructive tests, our products exceed standard requirements.
Stress corrosion and hydrogen embrittlement are known to be a threat for high-tensile structural steels, especially in environments containing chlorides.
We manufacture PC strand wire in a 3 or 7-strand configuration in both stress relieved and low relaxation grades. Diameters range from 3/8" (9.53 mm) to .600" (15.24 mm).
Prestressing wire and strands are used in bridges, cryogenic storage, industrial, commercial and residential buildings where safety is critical.
