Cup-lock Scaffolding System

Shaanxi Flourish Industrial Co., Ltd.'s Cup-lock Scaffolding System is the "vertical efficiency + cost-saving" benchmark for general construction-engineered with patented cup-blade locking technology to solve the "bolt complexity" of tube-and-coupler systems and the "high cost" pain point of ringlock scaffolding. Crafted from 3.2mm high-yield Q355 steel (20% lighter than standard tubes), it delivers 2-second node locking, 30kN/m² load capacity, and 40% faster assembly than traditional scaffolding. Certified by EN 12811 and TS EN 74-3, it's the cost-effective choice for global building, tower, and maintenance projects.

1. 3-Step Cup-Blade Quick Locking

 Unlike ringlock's 8-slot rosette (requires precise angle alignment) and tube-and-coupler's bolt tightening, our system uses dual-cup (top/bottom) + forged blade design . The locking process takes only 3 steps: insert ledger blade into bottom cup → slide top cup down → tighten with 1 hammer strike. Each node locks in 2 seconds, enabling 3 workers to erect 90m²/day-40% faster than tube-and-coupler and 15% more cost-efficient than ringlock (no complex rosette machining) . No nuts/bolts mean 90% fewer loose parts, eliminating assembly errors.

2. Lightweight High-Load Structure

 Made of 3.2mm high-yield Q355 steel (vs. ringlock's 3.2mm Q355 but with simpler node design), our system is 20% lighter than 4mm standard scaffolding tubes while maintaining 30kN/m² vertical load capacity-ideal for 6-20 story building facades and tower maintenance. The forged ledger blades (hardness ≥HB180) and pressed bottom cups (1.5mm thick steel) withstand 120% overload tests without deformation. For heavy-duty shoring, we offer 4.0mm thick standards that reach 45kN/m² load capacity .

3. 4-Core Components for Low Maintenance

 Unlike ringlock's 6+ component types, our system has only 4 core parts: standards, ledgers, transoms, base jacks . Standards feature cups welded every 500mm (adjustable height in 0.5m increments); ledgers come in 0.6-3.0m lengths (customizable for bay widths); omega transoms (1.3m) with inverted "T" sections support scaffolding boards without weather penetration . Fewer components reduce storage costs by 25% and simplify inventory management-critical for small-to-medium contractors.

4. 85μm Hot-Dip Galvanized Durability

We exceed industry 60μm standards with 85μm hot-dip galvanizing (TS EN ISO 1461 compliant) , achieving 1800h salt-spray resistance (vs. ringlock's 2000h but at 30% lower cost). The coating adheres tightly to cup joints (robot-welded for smooth surfaces), preventing corrosion in rainy or industrial environments. Components are reusable 250+ times (ringlock averages 200 times), cutting replacement costs by 40% over 5 years .

5. Versatile Vertical-Scene Adaptability

While ringlock excels at irregular curves, our system dominates vertical/regular structures: building facades (adjustable bay widths 0.6-3.0m), communication towers (lightweight for high-altitude transport), and maintenance platforms (quick assembly minimizes downtime). It also supports circular birdcages and stair towers via custom transoms-covering 90% of general construction needs at 20% lower cost than ringlock.

1. Standards (Vertical Posts)

Sizes: 0.5m-3.0m length, 48.3mm OD, 3.2mm/4.0mm thickness .

Feature: Dual cups (top: malleable casting; bottom: pressed steel) welded at 500mm intervals; spigot joints for height extension.

Role: Main load-bearing component, supports 4-way ledger connections per node.

2. Ledgers (Horizontal Beams)

Sizes: 0.6m-3.0m length, 48.3mm OD, 3.0mm thickness .

Feature: Forged steel blades (100mm length) at ends-resist bending and fit tightly into cups.

Role: Connect standards to form horizontal frames, 0.6-3.0m bay width adjustable.

3. Transoms (Platform Supports)Types:

Omega Transom (1.3m): Inverted "T" section, supports 5 scaffolding boards, weatherproof .

Intermediate Transom (0.9m-2.5m): Jaw sections hold boards, prevent mid-span bending.

Feature: Fabricated ends with locking devices to avoid dislocation.

4. Accessories

Base Jack: Adjustable 0-300mm, TS EN 74-3 certified for ground leveling .

Scaffold Plank: 2.4m length, anti-slip galvanized steel (matches omega transoms).

Toeboard: 200mm height, fits ledger tops for fall protection.

1. Installation Steps

a. Level ground → Place base jacks (adjust height to ±2mm) .

b. Insert 1.5m standards into base jacks; align bottom cups.

c. Insert ledger blades into bottom cups; slide top cups down and tighten with hammer.

d. Install transoms between ledgers; lay scaffolding planks (overlap ≥150mm).

e. Add guardrails (height ≥1.05m) and toeboards .

2. Maintenance & Inspection

Daily: Check top cups (ensure tight fit; re-tighten if loose).

Weekly: Inspect ledger blades for bending (replace if deformed).

Monthly: Clean galvanized surfaces (remove concrete residue); touch up scratches with anti-rust paint.

Annual: Test load capacity (use 120% rated weight) for reused components

1. Why choose cup-lock over ringlock for vertical projects?

Ringlock's 8-way angles are unnecessary for straight buildings-adding 30% to cost. Cup-lock's 4-way connection is sufficient for vertical structures, with faster locking and lower maintenance . For 6-20 story buildings, cup-lock cuts total cost by 15-25%.

2. Is it less durable than ringlock?

No-our 85μm galvanizing (1800h salt-spray) meets most project needs, while ringlock's 2000h resistance comes at a premium. Cup-lock's simpler node design reduces weld failure risk (only 2 cups vs. 8-slot rosettes), with 250+ reuses (50 more than ringlock) .

3. What's the minimum order quantity?

100 pieces (for small maintenance projects) with full customization: standard lengths (0.5m-3.0m), ledger sizes (0.6m-3.0m), and optional epoxy coating for coastal areas . We also offer compatible parts for existing cup-lock systems (K Lok, K Stage) .
