The client for this collaboration is a professional steel trading company based in Australia that primarily addresses local demand for various structural steel products. The company typically handles a wide range of procurement items with strict requirements, placing particular emphasis on supplier responsiveness and delivery flexibility. Initially, the client contacted us through business channels, clearly stating their need for a batch of ANSI H-beams and providing detailed specifications and procurement intentions. Upon receiving the request, we immediately prepared a quotation and carefully cross-checked the relevant parameters of the ANSI H-beams to ensure the accuracy of the quote. Recognizing that the client was a trading company and might have other steel procurement needs, we did not limit our response to the specific product they inquired about. Instead, we proactively compiled our company’s complete product catalog and sent it to the client, casually asking if they required any other types of steel. Unexpectedly, this small gesture became the key factor in securing this partnership.
After receiving the quotation and product catalog, the client responded promptly. In addition to confirming the details of the American standard steel H beam quotation, they specifically mentioned that they had a small-volume procurement need for structural square tubes in the near future. Although the quantity was modest, they required that both material quality and standards meet specifications, and they explicitly stated that they could place an order immediately if the price was right. We immediately seized this opportunity and inquired in detail about the specific specifications and material requirements for the square tubes. The client informed us that they needed square tubes made of Q355B steel that comply with the GB/T 6728-2017 standard, to be used for local building structures.
- Material: Q355B low-alloy high-strength structural steel
- Standard: GB/T 6728-2017 (Cold-Formed Hollow Structural Sections)
- Application: Local building structures in Australia
- Trade Terms: EXW — client arranges own transportation
About Q355B Square Tubes & GB/T 6728-2017
Q355B square tubes are a common category of structural steel. As a low-alloy high-strength structural steel, they offer superior yield strength and tensile strength compared to ordinary carbon steel. They can withstand greater loads for the same cross-sectional dimensions and possess excellent low-temperature toughness, making them suitable for a variety of complex structural applications and fully meeting the client’s core structural requirements.
The GB/T 6728-2017 standard is China’s dedicated standard for cold-formed hollow structural sections. It imposes strict requirements on the dimensional accuracy, shape deviation, and mechanical properties of square tubes, ensuring product quality and meeting the client’s stringent quality standards.
Immediate Stock Availability & Competitive Pricing
After fully understanding the client’s requirements for the square tubes, we immediately checked our inventory and found that we had the exact specifications in stock, eliminating the need for additional production. Leveraging our stock advantage, we immediately provided a competitive quote and explained to the client that all in-stock products had undergone rigorous quality inspections, fully complying with the GB/T 6728-2017 standard and Q355B material specifications, and were ready for immediate pickup.
Order Confirmed & Smooth Pickup Arranged
The client was highly satisfied with both our stock availability and pricing. Without hesitation, they quickly confirmed the square tube order. When discussing the terms of cooperation, the client proposed using EXW trade terms, with them arranging their own transportation to pick up the goods.
This approach was very convenient for us to operate and best met the client’s flexible needs. We immediately agreed and provided the client with detailed information regarding our factory address and the pickup process. We prepared in advance by stocking, inventorying, and inspecting the goods to ensure a smooth pickup when the client arrived.
Key Takeaway from This Collaboration
This collaboration with the Australian trading company not only secured us an order but also highlighted the importance of proactive service and sufficient inventory. We will continue to maintain this proactive and meticulous approach, expand our spot inventory, and optimize our service processes. We will not only meet our clients’ explicit needs but also proactively identify potential opportunities for cooperation. At the same time, we will strictly control product quality to ensure that every batch meets relevant standards, using our professionalism and integrity to earn the recognition of more overseas clients.
