Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Connection: British Type design with swivel mechanism enables angular adjustments, ensuring precise alignment and secure fastening of scaffolding pipes.
  • Structural Stability: Double coupler configuration reinforces scaffold integrity by connecting two pipes simultaneously, ideal for load-bearing applications in construction.

Key features

  • 1. Material Technology

    • With Q235 steel and galvanized surface treatment, you can achieve superior durability and corrosion resistance compared to standard steel couplers.*

  • 2. Interactive Design

    • With a 360° swivel design, you can easily adjust connections without repositioning scaffolding components, outperforming fixed couplers.*

  • 3. Performance Parameters

    • Certified to EN 12811-1 standards, you can handle heavy-duty construction loads with confidence, surpassing non-compliant alternatives.*

  • 4. Scenario Solutions

    • Designed for diverse construction scenarios, you can secure scaffolding in office buildings, courtyards, and industrial sites, unlike general-use couplers.*

  • 5. Certification Standards

    • With EN 12811-1, SASO, BS 1139, and EN 74 certifications, you can ensure compliance with global safety regulations, unlike uncertified products.*

Supplier's note

  1. Technical Breakthroughs:

    • Swivel Design: Enables 360° rotation (Pro model) for complex scaffold configurations.
    • Q235 Steel: 20% stronger than generic mild steel, meeting BS 1139 load standards.
    • Galvanization: Offers 3x longer lifespan in corrosive environments vs. uncoated couplers.

  2. Version Selection Guide:

    • Base Model: Ideal for standard residential or light commercial scaffolding (e.g., courtyard repairs).
    • Advanced Model: Suitable for mid-scale construction (e.g., office buildings) needing 180° adjustability and dual certifications.
    • Pro Model: Best for high-rise or industrial projects requiring 650 kg load capacity and full 360° rotation. With its triple-certified compliance, it ensures safety in extreme conditions like chemical plant piping.

*Pro model’s load capacity exceeds industry benchmarks by 25%.
