Since 1981, AMSYSCO has supplied and engineered post‐tensioned concrete reinforcement for large general and concrete contractors. AMSYSCO is one of the largest suppliers of unbonded post‐tensioning of high‐rise towers in the United States.

Their core philosophy is satisfying their construction customers need for outstanding engineering services and product quality. Their manufacturing plant is certified by the Post‐Tensioning Institute in order to satisfy the specification by structural and architects.

AMSYSCO believes that developers and owners of high‐rise buildings will benefit from the use of unbonded posttensioned concrete. It can allow for thinner floors, reduced building weights, improved seismic behavior, better real estate operational metrics and lower HVAC/energy costs.
