Shaanxi Flourish Industrial Co., Ltd.'s Coupler-type Steel Pipe Scaffolding redefines "flexibility + safety + economy" for complex construction sites-equipped with triple-coupler system (fixed/swivel/butt) and anti-slip serrated design to solve the "angle limitation" of cup-lock scaffolding and "high cost" pain point of ringlock systems. Forged from Q235B/Q355B steel with 65μm hot-dip galvanizing, it achieves 40kN single-coupler load capacity and 25kN/m² frame bearing, adapting to 95% of irregular scenarios like bridges, tunnels, and renovation projects.
Core Advantages (Break Through Scenario Limitations)
1. Triple-Coupler Universal Connection System
Unlike cup-lock's fixed 4-way nodes and ringlock's 8-slot rosettes, our system integrates three core coupler types to cover all connection needs:
Fixed Coupler: 90° vertical connection for wall-column formwork, with serrated contact surface (friction coefficient ≥0.8) to prevent slipping.
Swivel Coupler: 360° rotatable (0-180° adjustable) for inclined beams, tunnel arches, and irregular facades-solves the "angle mismatch" problem of rigid systems .
Butt Coupler: Steel sleeve + double-bolt design for pipe extension (48.3mm/51mm OD compatible), with 20% higher tensile strength than welded joints.
All couplers feature "double-nut + spring washer" locking (torque ≥40N·m), passing 5000 assembly-disassembly tests without loosening.
2. Cost-Efficient Yet Durable Structure
Adopting 3.0mm thick Q235B steel pipes (30% lighter than 4.0mm standard) and drop-forged couplers (hardness ≥HB190), our system balances weight and durability. The 65μm hot-dip galvanizing (exceeds industry 60μm standard) achieves 1500h salt-spray resistance-suitable for coastal and rainy environments . With a total cost per m² of $8-15 (40% lower than ringlock), components can be reused 200+ times, cutting long-term investment by 35% for small contractors .
3. Rapid Deployment for Emergency Needs
No pre-assembled frames required-single worker can complete 6-8 coupler installations per minute (2x faster than cup-lock). The system supports "on-site customization": pipes can be cut to length (0.5m-6.0m) and couplers adjusted instantly, reducing setup time for emergency projects (e.g., temporary bridges, post-disaster repair) by 50% . Matching accessories (adjustable base jacks, wall connectors) further simplify on-site operations.
4. Multi-Standard Safety Compliance
Each batch passes triple inspections:
Load test: Single coupler bears 40kN (4 tons) without deformation .
Anti-slip test: 15kN lateral force resistance (no pipe displacement) .
Corrosion test: 1500h salt-spray exposure (no red rust) .

FAQ (Clarify Flexibility & Cost Value)
1. Why choose this over cup-lock for irregular sites?
Cup-lock's fixed 90° nodes can't adapt to curves or inclines-requiring expensive custom parts. Our swivel couplers adjust freely, cutting customization costs by 80%. For renovation/tunnel projects, coupler-type scaffolding saves 2-3 days of setup time .
2. Is it less safe than heavy-duty ringlock?
No-our 40kN single-coupler load exceeds ringlock's 35kN, and anti-slip serrations prevent accidents. While ringlock is for ultra-heavy loads, coupler-type meets 95% of project needs at 40% lower cost. It's certified by global standards (BS 1139, EN 74) for safety .
3. What's the MOQ and customization scope?
MOQ is 500 pieces (pipes/couplers mix) for small projects. Customization includes: pipe lengths (0.5m-6.0m), coupler types (British/German/Japanese standards ), and coating (hot-dip galvanizing/Dacromet for coastal areas ). We also offer rental services for temporary needs.
Choose Shaanxi Flourish's Coupler-type Steel Pipe Scaffolding-not rigid cup-lock, not overpriced ringlock-for flexible, safe, and cost-saving solutions in any irregular construction scenario!
