What is the width range for DX51D+Z100 steel strip?
Standard widths typically range from 100-1500mm, with the choice of width determined by the specific application and processing requirements. For example, narrow strips of 100-300mm are often used for rolling shutters, while wide strips of 800-1500mm are often used for roofing panels and appliance casings. During production, wide strips can be cut to specific customer widths using a slitting process to meet individual processing requirements. The edge flatness of the cut strip must meet relevant standards to avoid burrs that could affect subsequent processing quality.
What is the zinc coating thickness for DX51D+Z100 steel strip?
Based on the conversion relationship between zinc coating weight and thickness (zinc density is approximately 7.14g/cm³), Z100 (100g/m² on both sides combined) corresponds to a zinc coating thickness of approximately 7 microns per side and a total zinc coating thickness of approximately 14 microns on both sides. In actual production, the zinc coating thickness will vary slightly from the standard minimum to ensure corrosion resistance requirements are met while also avoiding increased costs or coating peeling during processing due to excessively thick zinc coatings.
What is the coil weight of the DX51D+Z100 steel strip? The typical coil weight is 3-5 tons. The coil weight is designed primarily for transportation convenience and processing efficiency. A coil weight of 3-5 tons avoids the difficulties of loading and unloading due to excessive coil weight during transportation, while also reducing frequent coil changes during processing and improving production efficiency. For small processing companies or customers with special transportation needs, the manufacturer can customize smaller coil weights of 1-3 tons. For some large projects, larger coil weights of 5 tons or more can also be customized based on production line capacity.
What is the inner diameter of the DX51D+Z100 steel strip? The industry-standard inner diameter specifications are 508mm or 610mm. These dimensions are compatible with mainstream steel strip uncoiling equipment, ensuring stable steel strip rotation during processing and preventing coil jamming or deviation. The inner diameter tolerance is strictly controlled, generally not exceeding ±2mm. Furthermore, the inner ring steel strip must be wound smoothly, without loose coils or collapsed coils, to ensure smooth subsequent processing.
What are the surface finishes of DX51D+Z100 steel strip?
Mainly classified into three types: smooth, no spangle, rough, no spangle, and rough with spangle. The smooth, no spangle surface undergoes a smoothing process, resulting in high flatness and uniform gloss, making it suitable for subsequent surface finishing processes such as spraying and printing. It is widely used in applications requiring high aesthetics, such as home appliance housings and architectural decorative materials. The rough, no spangle surface retains the natural finish of galvanizing, resulting in relatively low flatness but lower production costs. It is suitable for structural parts requiring less demanding appearance. The rough, with spangle surface creates a natural spangle pattern, creating a unique aesthetic. Steel strip with this surface finish is chosen for some building exterior decoration and handicraft production.
