A joint pin is a fundamental component in scaffolding and construction. It is a cylindrical metal piece designed to connect two scaffolding pipes or tubes end-to-end, creating longer lengths. Joint pins secure the tubes in position and prevent movement, maintaining the structural integrity of the scaffold. They are crucial for assembling scaffolding structures of different heights and configurations. By securely fastening the tubes, joint pins ensure stability, safety, and load-bearing capacity. They play a pivotal role in constructing temporary platforms, support structures, and access systems, making them indispensable tools in the field of construction and maintenance.
