JOIST & SOFFIT BEAMS SYSTEM

 The SPI Keystone Joist System combines the long-span benefits of prestressed concrete with the advantages of a monolithic poured-in-place deck. This composite system is economical, fast to install, and lightweight.

 What sets SPI joists apart from other prestressed or post-tensioned systems is their flexibility. Joist spacing can be adjusted to accommodate almost any loading condition, and joists can be placed side by side as double joists to support heavy concentrated or lineal loads.



Our soffit beams provide prestressed reinforcement in the tensile zone, effectively emulating cast-in-place continuous span beams while adding the strength and reliability of prestressing. They include positive reinforcing and stirrups, ensuring structural integrity and performance
