Safety, Quality & Standards

Every Ringlock component undergoes full structural verification and raw material inspection before entering production line cutting and welding cycles.
[Raw Material Testing] ---> [Automated Robotic Welding] ---> [NDT & Rosette Shear Test] ---> [Hot-Dip Galvanizing] ---> [Batch Inspection]

Mill Certification & Traceability

Raw steel tubes are delivered with EN 10204 Type 3.1 material certificates confirming yield strength (>= 355 MPa), tensile strength (470 to 630 MPa), and elongation (>= 22%). Heat numbers and factory batch codes are stamped onto major structural components for complete traceability.

Welding Rigidity & Nondestructive Testing (NDT)
Process: Automated robotic MIG welding (GMAW) on all rosette-to-tube and ledger-head connections.
Inspection: Visual inspection per AWS D1.1/EN ISO 5817 Level C. Random 5% destructive shear testing on rosettes to verify weld shear resistance against slip under vertical loads.

Load Capacity Testing
Node connections undergo destructive shear and bending moment tests per EN 12811-3 and AS/NZS 1576. Verticals are tested in axial compression rigs to establish buckling curves across variable lift heights (1.0 m, 1.5 m, 2.0 m).

Structural Compliance
Europe & UK: Fully compliant with BS EN 12810-1/2 and BS EN 12811-1/2/3.
North America: Meets ANSI/SSFI SC100-5/05 and OSHA 1926 Subpart L load and safety parameters.
Australasia: Conforms to AS/NZS 1576.1/3 requirements.

Customization & System Compatibility

Inter-Fleet Compatibility
Our Ringlock system dimensions adhere strictly to the original Layher Allround geometry standard. Rosette spacing, wedge head angles, and spigot tolerances match standard market profiles, allowing seamless intermixing with existing rental fleets or jobsite inventories without axial mismatch or wedging jams.

FAQ

Q: Are your Ringlock components fully compatible with Layher Allround systems?

A: Yes. Our components are manufactured strictly to standard Layher Allround geometry specifications. Rosette dimensions, wedge head angles, and spigot tolerances match existing equipment, allowing complete intermixing with major rental fleets without binding or slop.

Q: How do you prevent corrosion on the inside of the scaffold tubes?

A: For all hot-dip galvanized products, components are submerged in acid pickling tanks and flux solutions before being dipped in molten zinc (450 degrees C). Vent holes drilled into vertical standards and ledger ends allow molten zinc to coat internal wall surfaces completely, ensuring internal and external rust protection (>= 85 µm thickness).

Q: What mill certificates and test reports do you provide with bulk shipments?

A: Every shipment includes EN 10204 Type 3.1 Material Test Reports (MTR) detailing chemical analysis and mechanical tensile/yield test results for each batch of raw steel. Third-party structural load test reports (SGS or TUV) per EN 12810/12811 can be supplied upon contract confirmation.

Q: What is the allowable leg load for your S355 steel Ringlock verticals?

A: When braced at 1.5 m vertical lift intervals using standard ledgers, an S355 grade vertical standard (48.3 mm OD x 4.0 mm wall) supports a safe working load (SWL) of approximately 50 to 60 kN per leg (using a safety factor of 2:1). Exact safe working loads depend on base jack extension lengths and diagonal bracing patterns.

Q: Can we request custom bay lengths or non-standard rosette spacing?

A: Yes. We manufacture custom bay sizes (e.g., 0.73 m, 1.09 m, 1.57 m, 2.07 m, 2.57 m, 3.07 m) and alternative rosette spacings (375 mm or 450 mm) to match specific formwork, shoring, or industrial plant engineering drawings.

Q: What is your standard lead time and container packing density for a 40ft container?

A: Standard lead time is 25 to 35 days for a 100-ton order. Vertical standards and ledgers are stacked in custom steel stillage pallets designed for 20ft or 40ft high-cube containers. Depending on local road weight restrictions, a 20ft container holds approximately 22 to 26 metric tons.
