Q1: What materials are used for Multi-Eye Plates?
A: Our Multi-Eye Plates are typically manufactured from high-strength structural steel (e.g., ASTM A36, Q345B, DH36) for optimal tensile strength. For corrosive environments, stainless steel (SS316L) or hot-dip galvanized carbon steel options are available .
Q2: Are Multi-Eye Plates certified for marine applications?
A: Yes. Our plates are compliant with international standards such as DNVGL-OS-E301 (offshore mooring) and can be certified by classification societies like ABS, Lloyd's Register, BV, or CCS upon request .
Q3: What is the working load limit (WLL) of your Multi-Eye Plates?
A: WLL ranges from 50 kN to 5,000 kN depending on plate thickness (10mm-100mm) and hole configuration. For example, a 50mm-thick plate with 4 eyes may have a WLL of 1,200 kN when tested to 2x proof load .
Q4: How are Multi-Eye Plates protected against corrosion?
A: Standard protection includes hot-dip galvanization (ISO 1461) for saltwater resistance, or epoxy paint for industrial environments. Custom coatings (e.g., polyurethane, zinc-rich primer) are available for extreme conditions .
Q5: Can Multi-Eye Plates be customized for specific hole patterns?
A: Yes. We offer fully customizable designs, including hole spacing, diameter, and plate dimensions. CAD drawings and FEA analysis can be provided to validate load distribution for unique applications .
Q6: What inspection reports are included with Multi-Eye Plates?
A: Each plate is supplied with a Material Test Certificate (MTC) and non-destructive testing (NDT) reports (e.g., ultrasonic testing, magnetic particle inspection) as standard. Impact testing and hardness testing can be added per project requirements .
Q7: How should Multi-Eye Plates be installed?
A: Ensure proper alignment of holes with connecting hardware (e.g., shackles, pins). Torque fasteners to specified values and use anti-seize compounds to prevent galling. Avoid overloading beyond the certified WLL .
Q8: What maintenance is required for Multi-Eye Plates?
A: Regularly inspect for cracks, deformation, or coating damage. Reapply protective coatings if galvanization is compromised. For high-load applications, annual NDT is recommended to verify structural integrity .
Q9: Are Multi-Eye Plates suitable for dynamic loading scenarios?
A: Yes. Our plates are engineered with radiused corners and stress-relieved edges to minimize fatigue failure in cyclic loading conditions, such as offshore mooring or heavy machinery suspension .
Q10: What is the typical lead time for Multi-Eye Plate orders?
A: Standard lead time is 20-30 days for non-custom orders. Custom designs may require an additional 5-7 days for engineering approval. Rush production options are available for urgent projects .
