Hot Dip Galvanized Adjustable Screw Jack U Head Prop For Ringlock Formwork

Featuring a high-quality Q235 structural steel body with hot-dip galvanized surface treatment, this adjustable scaffold base jack delivers excellent corrosion resistance and long service life. The full-length trapezoidal threaded rod and heavy-duty cast steel wing nut provide smooth height adjustment and stable load support under heavy concrete formwork pressure. Precision-machined threads and reinforced 4-hole base plates ensure reliable performance through multiple construction cycles.

Designed with Flat Base Jack and U-Head Jack options, the system meets different construction support requirements. The square 4-anchor-hole base plate provides secure fixing on concrete floors and steel platforms, while the U-head channel cradle offers stable beam support without additional adapters. Standard threaded rod lengths range from 400mm to 800mm, with customized diameters available for Ringlock, Cuplock, and frame scaffolding systems.

Produced under an ISO 9001 certified quality management system, every unit receives strict inspection before shipment. Thread fitting tests, nut rotation checks, and base plate welding inspections are performed to guarantee smooth operation under load, prevent thread stripping, and ensure compliance with EN12810 international safety standards. Complete batch traceability provides consistent quality control from raw materials to finished products.

Supported by more than 5,000 units of ready stock, we provide efficient supply solutions for global construction projects. Standard products can be delivered within 15–20 working days, with professional export packaging, custom labeling, mixed-container loading, and FOB/CIF shipping services available for worldwide customers.

Suitable for Ringlock scaffolding leveling, concrete slab formwork support, and structural load transfer applications, this adjustable base jack is widely used in high-rise buildings, bridge construction, industrial facilities, and tunnel projects. It provides precise vertical adjustment, strong stability, and dependable performance for demanding construction environments.
