Our GLL H-frame connection pin is specially designed for H-shaped scaffolding nodes. Its structure is optimized by engineering mechanics, made of high-strength alloy steel or stainless steel, and the surface is hot-dip galvanized or epoxy coated. It has the following technical advantages:
Self-locking wedge structure : The head of GLL pin adopts a two-way wedge design. After being inserted into the scaffolding rod, it is automatically locked by friction. No additional tools are required to achieve a stable connection, and the shear resistance is increased by 40%.
Modular size adaptation : Provide multiple diameter specifications from Φ12-Φ20mm, adapt to scaffolding pipes of different thicknesses (such as 48.3mm standard pipes), to ensure compatibility in multiple scenarios.
Anti-corrosion and durability：The thickness of the hot-dip galvanized layer is ≥80μm, and there is no rust in the salt spray test for more than 500 hours, which is suitable for coastal or high humidity environments.
Our GLL H-frame connection pins are manufactured using cutting-edge precision engineering technology to ensure that the geometric dimensions and connection performance of each pin strictly match the specification requirements of the scaffolding components to achieve a seamless fit. Its unique "H" shape design enables the connecting pin to provide higher stability and bearing capacity during the connection process, especially in complex construction site environments, and can cope with greater load requirements.
GLL H-frame connection pin is widely used in the following scenarios:
High-rise building facade construction: lightweight design (single piece weight ≤ 0.3kg) reduces manual handling intensity and improves high-altitude operation efficiency.
Bridges and industrial plants: load-bearing capacity increased by 25%, supporting the bracket connection of heavy-duty concrete pouring formwork.
Emergency repair and temporary support: fast disassembly and assembly function (single-person operation ≤ 15 seconds/node) all emergency response time.
GLL H-frame connection pin have passed the EN74-B scaffolding standard and BS1139-2:2001 certification, and comply with EU CE safety regulations. Its economic efficiency is reflected in:
Reusability: A single pin can withstand ≥1000 plug-in and pull-out cycles, and its life is 50% longer than that of traditional pins.
Cost savings: Modular design reduces accessory loss and reduces overall costs by about 30%.
Environmental value: The material recyclability rate is ≥85%, which is in line with the trend of green construction.
