Customer Background
The customer is a Brazilian building materials manufacturer with its own processing lines, equipped with mature slitting and roll forming equipment. They primarily produce roofing panels, wall panels, and light steel structure accessories. This procurement was driven by increased demand in their local market, coupled with quality issues from their previous supplier, prompting a desire to switch suppliers.
Communication Process
The customer submitted their request through our website (https://wanzhi-steel.com/). Their requirements were clear: DX51D material with an AZ60 coating for Galvalume steel coils.
Through their requirements and discussions, we identified the customer as a professional manufacturer. Our specialized sales manager promptly provided technical specifications matching the DX51D+AZ60 material, emphasizing its excellent formability for subsequent shearing, stamping, and roll forming processes.
We proactively inquired about the client’s specific requirements or preferences regarding material mechanical properties (such as yield strength and elongation), while also confirming the surface treatment condition. Based on our experience, we recommended the most economical coil weight range (e.g., 5-7 tons/coil) to balance the convenience of uncoiling on their production line with logistics costs. The client accepted this suggestion.
After receiving our quotation, the customer expressed satisfaction with the pricing. However, as a new supplier, they retained some reservations. Consequently, they decided to place trial orders of one container each for two specifications. They intended to evaluate our products before committing to bulk orders.
