1. Brief Introduction of Adjustable Steel Shoring System

Engineered for safety and longevity, JINGFANG® Adjustable Steel Props are built from 100% new steel — welded first, then galvanized, ensuring 360°galvanizing coverage on every seam, inside and out. 

We apply alkaline galvanization with a ≥70% pure galvanizing content, NSS salt spray tested over 72 hours — far exceeding the acidic galvanization plating that tarnishes within months. 

Our painting process applies the acrylic enamel finish which guarantees years of colorfast protection. 

Every base plate is full penetration welded with a visible weld bead as proof of complete fusion. The Four-Way Fork Head uses a non-parallel welding technique with a reinforced weld cap to enhance tear resistance at the joint. 

Material integrity is non-negotiable: wall thickness ±0.1mm, weight ±0.5%.  Every component, down to the tripod hinge dimensions, is built to standard without skimping. 

The entire system is fully tested to EN 1065:1998 across multiple heights, including maximum extension. No pre-galvanized tube. No shortcuts. No compromise.

1). Support Head

Connects the support prop to the formwork or beam above and safely transfers the load downward. Common types include U-Head and 4-Way Fork Head.

2. Top plate:

Located at the top of the inner tube, receiving the screw jack of the U-Head or 4-Way Fork Head. A built-in pin hole locks the screw jack in place, ensuring a secure, non-slip connection. It serves as the critical load-transfer point from the head to the inner tube.
