In the entire system of socket-type disc-lock scaffolding, the Ringlock Wedge Pin is the core load-bearing component that determines the overall stability of the scaffolding and avoids the risk of collapse during high-altitude construction. All the interlocking and locking of the uprights, horizontal bars, diagonal braces, and connecting plates relies entirely on the pin. This small component directly affects the construction safety of the entire high-formwork and bridge support frame. Hebei Hongxiang's Ringlock Wedge Pins are manufactured strictly in accordance with the JGJ/T231 national standard, strengthening the safety baseline for construction sites from four dimensions: mechanical load-bearing capacity, self-locking structure, corrosion resistance and durability, and fatigue resistance. This completely solves the high-frequency safety hazards of traditional fasteners and simple pins, such as loosening and falling off, insufficient load-bearing capacity, and corrosion and breakage.
In terms of mechanical performance, our Ringlock Wedge Pins are made of high-toughness special steel through integral forging, eliminating the shortcomings of ordinary stamped thin materials that are easily bent. After professional mechanical testing at the factory, the pull-out force after hammering and self-locking is consistently no less than 3kN, fully meeting the mandatory requirements of the national standard. During load transfer at the construction site, the lateral tension and vertical pressure generated by the horizontal and diagonal members are all borne by the pins. Even in scenarios involving large spans, high formwork, and heavy-load bridge construction, the pins will not bend, slip, or break. Compared to ordinary thin-material pins on the market, Hongxiang pins have a thickened cross-section, improving shear resistance by over 40%. Even if the frame is subjected to sudden impact loads, the locking structure at the nodes remains intact, preventing frame instability and collapse due to connector failure.
The self-locking wedge structure is the core safety design of this product. The pins feature a bidirectional wedge slope optimization, allowing workers to automatically lock them in place with a small hammer, eliminating the need for additional bolts or clips. During erection, even if the worker's hammering force is insufficient or the pins are not fully tightened, the wedge structure itself provides anti-slip restraint, preventing them from slipping out of the connecting plate holes and avoiding the dual risks of falling small parts causing injury and node detachment. The diagonal locking pins for the diagonal braces are designed with a distinct forward and reverse structure, allowing only unidirectional matching with the large hole in the disc. This prevents incorrect or incomplete installation by workers, which could cause imbalances in the frame's geometry. The horizontal bar straight locking pins are compatible with the small hole in the disc, ensuring a seamless fit between the pin and the connector. The tighter the engagement, the greater the load, creating a self-adaptive, self-locking mechanical structure that will not loosen under long-term vibration or wind loads.
The entire set of pins undergoes a hot-dip galvanizing process, significantly extending its safe service life. The entire set of pins is fully hot-dip galvanized, achieving a zinc layer thickness of 70μm. The coating is uniform on both the inner and outer surfaces, with no missed areas or peeling. Compared to spray-painted or cold-galvanized parts, this product has double the neutral salt spray resistance time. It is resistant to rust and corrosion expansion that can cause jamming under harsh conditions such as high salinity in coastal areas, humidity in the south, high moisture in tunnels, and snowmelt corrosion in winter. In long-term rental and turnover scenarios, repeated disassembly, stacking, and exposure to sun and rain will not cause rust peeling or steel embrittlement. Rust will not cause the pin cross-section to thin or reduce load-bearing capacity, ensuring a stable safety factor for multiple rounds of use.
Fully automated precision machining ensures interchangeable and consistent parts. Hongxiang's workshop is equipped with CNC stamping and grinding lines. The length, width, wedge angle, and thickness tolerances of the Ringlock Wedge Pin are controlled within a very small range. Each batch of parts has a uniform size standard and is completely compatible with our 60-series and 48-series disc buckle uprights, horizontal bars, and diagonal bars, eliminating matching jams and excessive gaps.
Off-brand pins on the market often have dimensional deviations, making parts from the same batch incompatible. Large gaps during installation lead to easy loosening under stress. Our factory's more than 20 standardized processes eliminate human error, allowing each pin to be freely matched across batches and specifications. The joints fit tightly, the load is evenly distributed, and there is no risk of localized stress concentration.
