Heavy-duty structural shoring system engineered with 60.5mm vertical standards and 8-hole ringlock rosette joints. Designed for massive concrete slab pours, bridge girders, and high-load civil engineering projects up to 270 kN/m².
The SY-1 Series System Shoring utilizes 60.5mm outer diameter steel pipe (wall thickness 2.6t~3.2t) paired with 8-direction rosette connection rings.
Integrated with heavy-duty U-Head Jacks and Base Jacks, SY-1 guarantees vertical alignment and prevents lateral buckling during massive concrete pour operations.
