The client is a Singapore-based refrigerator manufacturer with an established steel supplier. To optimize the company’s supply chain structure, they are evaluating and onboarding new suppliers through various channels.
In July of this year, the client found our website through Google search. After browsing this page (https://wzppgi.com/pre-coated-steel-coils-for-refrigerator/), they left an inquiry through the website. We responded promptly and had a brief communication with the client.
In their initial inquiry, the client provided preliminary specifications, specifying that the product would be used for manufacturing refrigerator exterior panels. Given the industry characteristics of pre-painted steel sheets for refrigerators—where most of the product is visible—there are strict requirements for surface quality, color consistency, coating adhesion, and processability. Our company’s business.
