Symons Sym-Ply is a modular, high-strength concrete forming system used to hold freshly poured concrete in place until it cures and hardens into vertical structures. Manufactured by Dayton Superior, it is primarily used in commercial and industrial construction to form walls, foundations, columns, and elevator cores.

Core Applications

• Vertical Concrete Structures: Ideal for shaping high-pressure concrete pours for mid-rise and high-rise foundations, shear walls, and stair cores.
• Rapid Column Formwork: Configured easily to mold square or rectangular structural support columns.
• Gang Forming: Assembled into large, pre-framed sections ("gangs") on the ground and lifted by crane to rapidly pour massive sections of concrete at once.

Key System Characteristics

• High Pressure Capacity: Engineered with ultra-strong 80 ksi steel frames to safely handle up to 1,500 pounds per square foot (psf) of concrete pour pressure.
• Fast Clamp Connection: Utilizes lightweight "Sym-Clamps" instead of older, time-consuming nut-and-bolt systems to connect adjacent panels together quickly.
• Steel-Ply Compatibility: Integrates seamlessly with standard Symons Steel-Ply systems without requiring custom adapters or transitional filler hardware.
• Built-in Safety Features: Equipped with integrated tie-off bars to satisfy OSHA fall protection safety guidelines for construction crews working at heights.
