AREMA Joint Bar

Description


We strictly control quality from raw material, production equipment and methods, mechanical property, inspection and packaging.
We provide complete QCS reports and third party inspection reports.

The advantages at a glance:
 Strict production management and quality control—CDR products quality is 15% higher than AREMA standard.
 Accurate lead time, monthly update of production schedule
 In time delivery, weekly update of shipment status
