S12 Pool steel is a ductile steel with a deformed (ribbed) profile that is specifically designed for concrete swimming pools. It is easy to bend on site, making it ideal for shaping the steel to suit the curved requirements of modern day pools. Pool steel controls cracking and ensures the strength of the pool structure, whilst providing maximum design flexibility. Stocked in 6m lengths. High-strength 250S Grade soft deformed reinforcing steel for concrete Not heat tempered to allow for easy bending on-site to design requirements
