AI Overview
JIS Type Pressed Fixed Couplers are Japanese Industrial Standard (JIS A 8951) compliant fasteners used to securely connect 48.6mm scaffolding tubes at 90-degree angles. Made from pressed steel (often Q235 or SPHC) with galvanized surfaces, these lightweight, cost-effective couplers provide high-strength rigid connections for structural, vertical, or ledger-to-standard applications. 
Key Features and Technical Specifications: 
  • Standards: Adhere to JIS A 8951 for quality, safety, and performance.
  • Material: High-grade pressed steel (Q235/SPHC) treated for corrosion resistance.
  • Dimensions: Designed for 48.6mm outer diameter pipes (standard Japanese scaffolding size).
  • Weight: Typically lightweight, ranging from approximately 0.56kg to 0.64kg per piece.
  • Application: Ideal for vertical and horizontal (90-degree) securement in tube-and-coupler scaffolding, ledger-to-standard connections, and bracing.
  • Types: Available as standard double fixed (right-angle) couplers for connecting two pipes. 
Advantages: 
  • Cost-Effective: Pressed steel construction makes them a cheaper alternative to drop-forged couplers.
  • High Rigidity: They prevent rotation, ensuring high stability under load.
  • Easy Installation: Lightweight, enabling efficient assembly and disassembly on-site. 
Commonly available from manufacturers like Rizhao Weiye Tools and similar, these are essential for building secure, durable temporary platforms.
