Product Usage

EN74 Galvanized Drop Forged and Pressed Scaffolding Double Swivel Couplers are essential components for connecting scaffolding tubes securely and flexibly. They allow for the construction of adaptable scaffolding setups in various projects, from high-rises to industrial plants and renovations. These couplers enable connections at different angles, which is vital for creating stable platforms around irregular buildings or sloping surfaces. They also facilitate quick assembly and disassembly for maintenance work, providing easy access to necessary areas.

Product Parameters

Parameter	Details
Material	Drop - forged models are mainly crafted from high - quality Q235 carbon steel, while pressed versions use a suitable alloy. This material provides excellent strength and durability, capable of withstanding heavy loads and harsh working conditions.
Dimensions - Tube Compatibility	They are designed to fit standard scaffolding tubes, typically with an outer diameter of around 48.3mm. However, they can also be customized to fit other common sizes in the market, such as 48mm or 51mm, ensuring broad compatibility across different scaffolding systems.
Weight	The weight of these double swivel couplers varies according to the manufacturing process and size. Drop - forged couplers usually weigh approximately 1.1 - 1.2 kg each, and pressed couplers are slightly lighter, around 0.9 - 1.0 kg. This weight balance makes them easy to handle during installation and transportation.
Surface Treatment	Both drop - forged and pressed couplers are given a galvanized finish. The galvanization process involves coating the coupler with a layer of zinc, which offers outstanding corrosion resistance. This ensures the couplers can be used in various environmental conditions, including humid construction sites or areas with chemical exposure.
Load - Bearing Capacity	They are designed to bear substantial loads. Generally, these double swivel couplers can withstand a vertical load of up to 25 - 30 kN and a horizontal load of 10 - 15 kN, depending on the specific model and manufacturing standards. This high load - bearing capacity makes them reliable for supporting the weight of workers, tools, and construction materials on scaffolding.
Angle Adjustability	As their name implies, double swivel couplers offer a high degree of angle adjustability. They can typically rotate up to 360 degrees at the swivel joints, allowing for the connection of tubes at any desired angle, which is vital for creating complex and adaptable scaffolding structures.

Product Advantages

Exceptional Strength and Stability:Thanks to the drop - forged or pressed manufacturing process and the use of high - quality Q235 carbon steel, these couplers exhibit remarkable strength. The forging process refines the metal's grain structure, enhancing its mechanical properties. This strength ensures that scaffolding structures remain stable even under heavy loads and adverse weather conditions. For instance, in high - wind regions or during the construction of tall buildings where the scaffolding is subject to significant lateral forces, these couplers can maintain the structure's integrity, reducing the risk of collapse and guaranteeing worker safety.

Superior Corrosion Resistance:The galvanized surface treatment is a significant advantage of these couplers. Zinc, as a sacrificial metal, safeguards the underlying steel from corrosion. This is especially important in construction environments where the couplers are frequently exposed to moisture, rain, and various chemicals. The corrosion - resistant property not only extends the couplers' lifespan but also cuts down on maintenance costs. Couplers with a galvanized finish can be used for many years without significant degradation, making them a cost - effective choice in the long term.
