Produced from high-strength alloy steel with strict chemical composition control (C: 0.25–0.35%, Mn: 0.60–1.00%, Si: 0.20–0.60%, Cr/Ni/Mo as specified), our container twistlock cones withstand heavy mechanical stress under rigorous operational conditions. Each unit adheres to strict dimensional, hardness, and mechanical performance standards. We provide material certificates (MTC), dimensional inspection reports, and mechanical test reports upon request.
Features, Advantages & Benefits
Our Investment Casting Container Twistlock Cones feature an integrated one-piece structure formed through investment casting, eliminating weak points from splicing or welding. Surfaces receive precision machining and optional anti-rust, anti-corrosion treatments for marine environment resilience.
Advantages include high tensile strength, strong impact resistance, wear-resistant properties, and extended service life. Every piece undergoes strict quality inspection before release.
Benefits for operators: reduced risk of container fixing failure, lower maintenance and replacement costs, improved safety during port stacking and vessel shipping, plus consistent performance in harsh marine and coastal conditions.
Applications
These twistlock cones are widely used across shipping container securing, container yard stacking, port terminal logistics, truck container locking systems, and intermodal transportation. Additional applications include logistics equipment manufacturing, container engineering project customization, marine transportation accessories, and related container hardware assemblies.
