Cast Iron Coupler

Cast Iron Couplers are commonly used connecting components in building scaffolding systems,made of gray cast iron or ductile iron as raw materials,made through the casting process,mainly used to connect scaffolding steel pipes(vertical bars,crossbars,inclined rods)at a specific angle to build a temporary support frame.Compared with forged fasteners,their manufacturing cost is lower,and they are widely used in light load scenarios such as small and medium-sized buildings,interior decoration,and temporary scaffolding,making them a choice that takes into account both economy and basic connection needs.In terms of manufacturing,Cast Iron Couplers are made by using the sand casting process,in which molten cast iron liquid is poured into a mold and shaped,and then deburred and surface treated.Although the casting process is prone to a small number of internal shrinkage holes,defects can be controlled by optimizing the mold design to meet the needs of light-load scenarios.The surface is mostly painted or simply anti-rust,and the service life is about 3-5 years,which is suitable for short-term projects with limited budgets.In terms of performance,Cast Iron Couplers have a tensile bearing capacity of about 8-12kN,which can meet the needs of daily light loads,but the impact resistance is weaker than that of forged fasteners,and they are not suitable for heavy loads or super high-rise buildings.Its structure is simple,easy to install,and can be reused after disassembly and inspection without cracks.When using,it is necessary to follow the"Steel Pipe Scaffolding Fasteners"(GB 15831-2016)and avoid using it for scaffolding or heavy equipment support scenarios above 50 meters.Regularly check for cracks and bolt slips,and store them against moisture and rust to ensure safe use.
