Frequently Asked Questions
What applications is alloy chain suitable for?
Alloy chain is commonly used on board ships for rigging, cargo lashing, towing, lifting, and securing deck equipment. Its high strength-to-weight ratio makes it ideal for heavy lifting and mooring operations where reliability is critical.
What is the working load limit (WLL) and how is it determined?
The WLL of alloy chain varies with chain diameter and grade. For example, a 10 mm Grade 80 chain typically has a WLL of 2.5 tonnes, while a 32 mm Grade 100 chain can support up to 25 tonnes. Always refer to the provided load charts and certifications for the exact WLL of a specific chain size.
Is alloy chain resistant to corrosion in marine environments?
Yes, this alloy chain is designed for marine use. It is either black-painted or hot-dip galvanized to protect against saltwater corrosion. Regular maintenance, including freshwater rinsing and periodic lubrication, will further extend its service life.
What standards does the chain comply with?
The chain is manufactured to meet international standards such as EN 818 and DIN 5688, ensuring consistent quality, safety, and performance. Each batch is tested and provided with a manufacturer's certificate upon request.
