This customer purchased two colors of color-coated aluminum coils: blue and gray. The thicknesses were 0.31mm, 0.37mm, and 0.47mm, and the width was 914mm.
Client Background
A medium-sized building materials processing and trading company in Cameroon primarily processes imported semi-finished raw materials (such as color-coated aluminum coil, galvanized steel coil, and PPGI coil) into building products such as roof tiles and wall panels. These products are supplied to local real estate and construction projects for use in residential exterior wall and roof renovations.


Communication Process
Initial Contact
The client proactively requested a quote through the website https://wanzhi-steel.com/. The request clearly specified three thicknesses and a “transparent blue backcoat.”
In-depth Communication
Our sales team responded within one hour of receiving the inquiry. Rather than providing a quote directly, we first conducted an in-depth video conference with the client to confirm the client’s application scenarios and further technical details.


Application Confirmation
The client confirmed that the material was primarily intended for roofing systems in high-end residential and commercial buildings.
Technical Details
We proactively inquired about and confirmed the base alloy type (ultimately AA3003 H24), the colors of the front coating (blue and gray), the coating system, and the packaging method.


Confirmation of Cooperation
The customer was quite satisfied with the price and professionalism our team provided and agreed to cooperate. Since this was their first collaboration, the customer indicated that the order volume was not large. If the product quality satisfies their expectations, they would continue to place orders and increase their purchases of other steel coil products.
