3. Manufacturing Process of screw jacks scaffolding: From Raw Steel to Precision Jack

Step-by-Step Workflow

Material Selection: High-tensile Q235/345 carbon steel, tested as per ISO 6892.
Forging/Die-Casting: Stem and nut shaped by CNC turning and hammer forging (see below arrow diagram).
Precision Machining: CNC threading, slotting, and dimensional controls with ±0.1mm tolerance (ISO 286-1 fit standards).
Surface Treatment: Hot-dip galvanization (80μm–120μm), or electrostatic powder coating, meeting ISO 1461.
Assembly: Stem, base plate, nut, and saddle coupling—each tested for load & runtime cycles.
Quality Inspectorate: Load test (EN 12811), corrosion fatigue (ISO 9227), and individual batch serial traceability.
Packing & Dispatch: Palletized as per customer specs; barcoded and certified.

Quality Standardization & Product Longevity

Each batch tested with >100,000 cycles mechanical fatigue (EN 12811-3) and subjected to salt spray (ISO 9227, ≥96h pass rate).
Traceability via barcode tracking, mill test certificates & heat numbers (ISO 9001).
Life expectancy typically 5–10 years, 15 years if hot-dip galvanized under ISO 1461.

Industry Insight: WRK Formwork has supplied over 3.8 million screw jacks scaffolding units worldwide, with a complaint rate <0.004% in 2022 (source: internal QA data, 2023).

4. Application Scenarios & Technical Advantages: Real Deployment of screw jacks scaffolding

Key Application Sectors:

Petrochemical & Energy: Turnarounds require rapid-shoring with anti-corrosive jack bases and forged couplers (safety margin >2.5x per ISO 12944).
