FAQ

 

1. What is a Scaffolding Swivel Coupler?
A Scaffolding Swivel Coupler (also called a Swivel Clamp or Right-Angle Coupler) is a key forged steel fitting used to connect two scaffold tubes (pipes) at any angle. Its unique pivoting design allows the two jaws to rotate independently, enabling secure, non-parallel connections essential for building rigid three-dimensional scaffolding structures.

2. What are the primary applications?
It is an indispensable component in tube-and-coupler scaffolding systems for:

Connecting Ledgers to Standards: Creating the primary horizontal to vertical joints.

Fixing Diagonal Braces: For lateral stability and wind bracing.

Formwork & Shoring Support: In concrete construction.

Creating Complex Angles: Where tubes meet at angles other than 90° or parallel.

Temporary Structures: For stages, event setups, and repair works.

3. What materials are your swivel couplers made from?
We manufacture them from premium materials for maximum safety and durability:

Body: Drop-Forged Carbon Steel (Grade Q235B or equivalent S235JR). The forging process provides superior grain structure and impact resistance.

Bolts, Nuts & Washers: Grade 8.8 High-Tensile Steel, hot-dip galvanized.

Standard Finish: Hot-Dip Galvanizing (HDG) to ISO 1461 / ASTM A153 for maximum corrosion resistance on construction sites.

4. How can I request a quotation or sample?
For a fast and accurate quote, please provide:

Product Name/Standard (e.g., Swivel Coupler for 48.3mm tube to BS EN 74-1).

Required Quantity.

Destination Country/Port.

Any special requirements (custom marking, packaging).

5. What scaffold tube sizes are they compatible with?
Our standard couplers are designed for the global industry standard tube:

Nominal Bore: 1-1/2 inch (1.5").

Outer Diameter (OD): 48.3mm.

Other Sizes: Available for 42mm OD, 60.3mm OD (2-inch), and other specifications upon request.

6. How is it installed and tightened correctly?
Proper installation is critical for structural integrity:

Place the two scaffold tubes into the jaws of the coupler.

Ensure the coupler sits squarely with no gaps at the heel (where the tube meets the coupler body).

Hand-tighten the single high-tensile bolt and nut.

Final tighten using a scaffolding spanner (wrench) to the recommended torque (~40-50 Nm). Overtightening can damage the coupler or tube.

7. What is the difference between a Swivel Coupler and a Double/Sleeve Coupler?
Swivel Coupler: Connects two tubes at any angle (one fixed, one adjustable via the swivel).

Double Coupler (Fixed Coupler): Connects two tubes in parallel, end-to-end.

Sleeve Coupler (Joint Pin): Connects two tubes end-to-end in a straight line.
These are complementary fittings used together in a complete system.

8. What is your MOQ (Minimum Order Quantity)?
Standard HDG Swivel Couplers: MOQ 1,000 pieces.

Custom Marking/OEM Orders: MOQ 5,000 pieces (negotiable based on design complexity).

Samples: Available for testing and approval.

9. What is your production lead time?
Samples: 7-10 working days.

Standard Orders (from stock/semi-finished): 15-20 working days.

Full Production/Custom Orders: 25-35 working days.

10. Can you provide other scaffolding fittings?
Yes, we are a full-range scaffolding manufacturer and can supply:

All types of couplers (Double, Sleeve, Putlog, Girder).

Scaffold Tubes (Standards, Ledgers)

Boards, Base Plates, and Adjustable Jacks

Complete system solutions and design support.

11. Do you offer customization or OEM services?
Absolutely. We are a leading OEM supplier to major brands and can provide:

Custom Drop Forging with your logo or part number stamped/forged into the body.

Special finishes (different galvanizing standards, color powder coating for site identification).

Private label packaging (boxes, bags, pallets).

12.  How are the couplers packaged for export?
We use robust, commercial-grade packaging:

Standard: Bundled in sets of 25 or 50, wrapped, and packed in strong cartons or wooden boxes.

Bulk/OEM: Master cartons or 1-ton sacks, palletized and shrink-wrapped for sea freight.

All packages are clearly labeled.
