1250mm Hot Dipped Galvanized Steel Sheet DX51D Zinc Sheet Metal

1250mm Hot Dipped Galvanized Steel Sheet DX51D Zinc Sheet Metal

1.Product Overview

Hot dipped galvanized steel sheet is used where the steel substrate needs metallic zinc protection before fabrication or installation. This product is suitable for container parts, building components, roofing related fabrication, and general industrial sheet processing where thickness range, zinc coating, and surface condition need to be selected together.

This page is centered on DX51D galvanized sheet with a featured width of 1250mm. The listed thickness range of 0.15-3.8mm and zinc coating range of 40-275g/m2 make it suitable for both light gauge sheet conversion and heavier fabricated parts.

2.Technical Solution

The product uses a hot dip galvanizing process in which the steel sheet is coated with zinc to create a barrier layer between the steel and the service environment. In practical use, corrosion performance depends on zinc coating mass, cut edge exposure, drainage condition, storage method, and whether the sheet is used indoors or outdoors.

The page also lists multiple spangle options including regular, minimized, big, and zero spangle. Spangle selection mainly affects surface appearance and downstream finishing consistency. Surface treatment options such as passivated, oiled, and anti-finger acrylic coating help adapt the sheet to different storage, transport, and fabrication conditions.

For fabrication routes such as bending, profiling, and container component processing, thickness and coating mass should be selected together. Thin gauges are more suitable for easier forming, while thicker gauges provide more rigidity for structural or semi-structural parts.

3.Specifications

4.Application

• This material is suitable for container plate related fabrication, roof components, wall components, garage doors, and general building sheet parts.
• It can also be used for industrial enclosures, appliance housings, formed sheet parts, and other galvanized steel components where metallic coating protection is required before final assembly or painting.
• For outdoor applications, final durability depends not only on zinc coating mass but also on profile design, overlap detailing, drainage, and actual exposure conditions at the installation site.

5.Processing

• The sheet can be used for cutting, bending, profiling, punching, and general sheet metal fabrication.
• For visible parts, spangle type and secondary surface treatment should be selected before production because they affect final appearance and handling behavior.
• For coil to sheet conversion or container part processing, the forming route should be checked against sheet thickness and required rigidity. For outdoor service, storage and installation details should be controlled so that water is not trapped at overlaps, joints, or cut edges.

6.Advantages

• The 0.15-3.8mm range covers both light gauge sheet processing and heavier fabricated components.
• The 40-275g/m2 zinc coating range allows the product to be selected according to actual corrosion requirement instead of using one fixed coating level for all projects.
• The 1250mm featured width is practical for mainstream sheet conversion and fabrication planning.
• Multiple spangle options allow the sheet to be matched to visible surface requirements and downstream finishing needs.
• Passivated, oiled, and anti-finger surface conditions give more flexibility for storage, handling, and fabrication routes.

7.How to Choose

• Choose zinc coating level according to the actual service environment. For lighter indoor or protected use, a lower coating level may be acceptable. For exterior or more demanding use, a higher coating level within the listed range is generally more suitable.
• Choose minimized or zero spangle when surface uniformity is more important. Choose regular or big spangle when standard galvanized appearance is acceptable or intentionally specified.
• Choose passivated surface for standard storage protection, oiled surface for temporary transport protection, and anti-finger treatment when cleaner visible surface handling is required.
• Choose thickness according to rigidity and forming route. Thin gauges are more suitable for lighter formed parts and easier processing. Thicker gauges are more suitable for stronger structural parts and higher stiffness requirements.
