Client Profile

This Saudi enterprise is a roller shutter door manufacturer. Its core business covers the production of various roller shutter doors, which require large volumes of hot-dip galvanized steel coils as raw materials. The coils are processed into door panels via profiling, bending and punching procedures.

The client runs an independent spraying workshop and also manufactures color-coated roller shutter doors to meet diverse demands from end customers.

 

Reasons for Switching Suppliers

The customer’s previous supplier had persistent drawbacks as below:

1. Delayed deliveries: Unstable lead times disrupted the client’s production schedule

2. Uncompetitive pricing: No favorable long-term cooperation discounts

Confirmed Project Solution

Roller shutter production involves repeated bending processes, so the raw material must feature excellent formability. Given Saudi Arabia’s high-temperature outdoor exposure environment, we guaranteed our coils would not suffer zinc peeling, oxidation, white rust or corrosion. We therefore selected DX51D+Z hot-dip galvanized steel coils compliant with both Chinese national standards and European standards.

Production Process of This Order

1. Raw Material & Process Selection

We use high-quality cold-rolled substrate. DX51D is the most commonly used substrate for galvanized coils, perfectly suited for the post-processing of roller shutters, allowing customers to easily cut it into galvanized sheets, generate profiled sheets, and then roll-coate or punch them. The entire production process uses standard hot-dip galvanizing technology.

2. Quality Inspection

We precisely control zinc coating weight, coil width and coil weight. Every finished coil undergoes full inspection for thickness tolerance and surface condition. Our QC department conducts professional tests on bending performance, impact resistance and salt spray tolerance of galvanized coils. Strict controls eliminate missed galvanization and ensure solid, uniform zinc coating.

 

3. Packaging

Each coil is wrapped with protective film, reinforced with steel strapping and lined with waterproof kraft paper for moisture resistance. All goods were loaded into two 40HQ containers and shipped to Saudi Arabia.
