Unlike generic props that suffer from thread damage and rust, Hyson props are manufactured in our Nantong facility using Cold Rolled Thread technology. This process retains the steel's structural integrity, ensuring smooth adjustment even after years of rough handling—a critical feature for equipment rental companies. Backed by our experience supplying CCCC infrastructure projects, every prop undergoes rigorous load testing to ensure safety factors meet international standards (EN 1065 / BS 4074).

Product Features
- Rolled Threads for Longevity: We use thread rolling machines rather than cutting lathes. This means no material is removed, resulting in a stronger thread that resists jamming by concrete slurry—extending the prop's service life by 30%.
- Safety Hand Clearance: Designed with a 100mm safety zone at the top of the thread to prevent the inner tube from crushing the operator’s hands during collapse/release.
- Self-Cleaning Collar: The specialized cast steel nut features a self-cleaning groove that pushes dirt and dried concrete out of the threads during adjustment.
- Heavy-Duty Corrosion Protection: For rental fleets, we recommend our Hot-Dipped Galvanized (HDG) option (min. 60μm zinc), which offers superior rust resistance compared to painted props, ensuring a higher resale value.
- Robust G-Pin Connection: High-tensile steel G-pins ensure a secure lock under heavy loads, preventing accidental slippage.
Application Scenarios
- Slab Formwork Support: Acting as the primary vertical support for timber beams (H20) or steel formwork in floor casting.
- Re-shoring (Back-propping): Supporting cured concrete slabs to distribute loads when pouring upper floors, essential for multi-story speed construction.
- Renovation & Demolition: Providing temporary structural support for walls, lintels, and beams during repair works.
- Trench Shoring: Used horizontally as adjustable struts to support trench walls (with appropriate adaptors).
