FAQs
Q: How do you package and protect 57 kg rails for export?
A:Packaging options include anti-corrosion oil, plastic wrapping, timber cradles and steel strapping within wooden crates or bundled for container/break-bulk shipment. We recommend packaging matched to transit mode and destination climate—this is defined in the T/C.
Q: What are typical hardness ranges for R260 rails?
A: Hardness targets depend on mill practice and any heat treatment. As a guideline, normalized rails may have lower hardness than quenched & tempered rails. Always accept hardness ranges specified in the T/C and verified on the MTC.
