In the global scaffolding and formwork engineering field, the reliability of the connection system directly determines the safety and stability of the overall structure. Today, we proudly introduce to the industry a series of high-performance pipe connection solutions—covering JIS Pressed Coupler, Famous Putlog Coupler, the widely adaptable China Gravlock Coupler, and the fully customizable Custom Gravlock Coupler. This product line not only represents a high level of professionalism in connection technology but also demonstrates comprehensive service capabilities, from standard compliance to flexible adaptation.
Standards Lead, Quality Foremost Our JIS Pressed Coupler strictly adheres to the Japanese Industrial Standard JIS A 8951-1995, and the raw materials comply with JIS G3101 SS330 material specifications. Each batch of products is based on a high-quality control philosophy, passing testing by the internationally authoritative SGS organization, and providing excellent test data reports to ensure that it fully meets high-standard engineering requirements in terms of strength, durability, and safety. This series of couplers can be used with steel pipes to build complete scaffolding systems. Its accessory system is comprehensive, including fixing couplers, swivel couplers, sleeve connectors, internal pins, beam clamps, and base plates, providing users with systematic assembly possibilities.
Diverse Adaptability, Flexible Customization
In addition to standard JIS couplers, we also supply the widely recognized Putlog Coupler, suitable for various lateral support scenarios; we also offer our self-produced China Gravlock Coupler, which excels in cost-effectiveness and practicality. For customers with special design or engineering matching needs, we provide in-depth customization services for Custom Gravlock Couplers, where structure, dimensions, and load-bearing specifications can all be produced according to drawings, truly realizing "what you need, we can manufacture."
Extended Process and Service
All coupler surfaces are available with electroplating (silver-white) or hot-dip galvanizing (yellow), ensuring both corrosion resistance and visual identity. Packaging also supports personalized arrangements, typically using a combination of cardboard boxes and wooden pallets, and can be designed according to customer requirements. We also offer corporate logo embossing services to help customers strengthen their brand identity.
