Import 60*40 Crane Rail Flat Bar — Buy in wholesale FOB from Supplier in China

The 60*40 Crane Rail Flat Bar from Glory Diamond Industry Limited is a hot-rolled stainless steel structural section measuring 60 millimetres in width and 40 millimetres in thickness, supplied in grade 304 (1.4301) austenitic stainless steel. This profile is engineered for crane rail support and heavy-load structural applications where corrosion resistance and dimensional stability under dynamic loading are critical. The supplier cites conformance to GB, AISI, ASTM, SAE, EN, BS, DIN, and JIS standards, with normalised, annealed, or quenched and tempered heat treatment options available.

Grade 304 stainless steel contains 18-20% chromium and 8-10.5% nickel by weight, providing excellent resistance to atmospheric corrosion and many industrial chemical environments, though it is susceptible to chloride-induced pitting in marine or de-icing salt exposure. The hot-rolled production process yields a mill-scale surface finish with dimensional tolerances per GB/T 702 or EN 10058 for flat bars, typically plus or minus 1mm on thickness and plus or minus 2mm on width for this size range. Normalising refines grain structure for improved toughness, annealing restores corrosion resistance after cold working, and quench-plus-temper treatments develop higher strength grades when specified. Standard straightness tolerance for hot-rolled flat bar is 0.4% of length, though this is not supplier-confirmed.

Primary buyers include port crane manufacturers, warehouse logistics system integrators, heavy equipment OEMs, and structural steel distributors serving industrial construction. The 60*40 section suits top-running and underhung crane rail installations where the flat bar distributes wheel loads to supporting girders. Glory Diamond Industry offers third-party inspection by SGS, BV, or other nominated agencies prior to shipment. Exact MOQ, lead time, and unit pricing are not stated in the listing and must be confirmed directly with the supplier.
