PC Strand
Post-tensionde unbounded prestressed concrete bar is suitable for cast-in-place concrete of long-span and wide buildings, large load prefabricated beam and other construction. It has the characters of no need room for future expansion and grout-on, convenient use, material saved, bend easy.
