An inquiry was received from a customer in Singapore looking for high-standard steel pipes. After initial pricing comparisons, the customer originally noted our quote was higher than alternative suppliers, but chose to proceed with a trial order of 10 containers. Impressed by the material quality, they have since established a long-term partnership, ordering monthly shipments from our facility.
