basic information
**What is Prestressed Concrete (PC)?** Prestressed concrete (PC) is concrete that has been pre-compressed using the tensioning force of PC steel materials, overcoming the weakness of reinforced concrete in terms of tensile strength. Due to its ability to suppress cracking and its excellent recovery properties, it enables long spans for structural members and enhances the durability of buildings. Additionally, prestressed reinforced concrete (PRC), which uses mild prestressing and reinforcement within the members, possesses performance characteristics that are intermediate between reinforced concrete and PC. *For more details, please refer to the PDF document or feel free to contact us.*
