DX53D Z120 Hot Dipped Galvanized Steel Sheet Minimized Spangle

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 positioned for roofing sheet and formed panel applications where zinc coating mass, surface condition, and sheet rigidity all influence downstream performance.

The featured configuration on this page is DX53D Z120 with minimized spangle at 2.0mm thickness, 1000mm width, and 5800mm length. That combination is suitable for projects that need a coated sheet with practical corrosion protection and a more controlled visible surface than standard regular spangle material.

2.Technical Solution

This product uses a hot dip galvanized route with zinc coating from 40 g/m2 to 275 g/m2, with Z120 as the featured configuration on this page. In practical use, zinc coating mass is one of the main variables for corrosion performance because it determines how much sacrificial zinc is available before the steel substrate becomes exposed at the surface or cut edge.

The page also lists several spangle conditions including regular spangle, minimized spangle, big spangle, and zero spangle. Minimized spangle is generally selected when a more uniform surface is required for visible sheet applications or for more consistent downstream forming and finishing.

Surface treatment options include passivated chromated, oiled, and anti-finger acrylic coating. These treatments affect storage behavior, transport protection, and surface cleanliness during fabrication, especially when the sheet is used in roofing panels or exposed cladding parts.

4.Application

This material is suitable for roofing sheets, roof components, external wall sheets, garage doors, and window blind related panels in construction use.

It can also be used in household appliance parts, transportation related sheet parts, industrial control cabinets, refrigeration equipment housings, and furniture sheet components where metallic coating protection is required before fabrication or final assembly.

For roofing use, service behavior depends not only on the zinc coating mass but also on profile design, overlap detailing, drainage, and local exposure environment.

5.Processing

• The sheet can be processed by shearing, bending, profiling, and general sheet metal fabrication according to the final panel design.
• For roofing sheet conversion, the forming route should be matched to the 2.0mm gauge and the selected surface treatment. When visible surfaces are important, handling and storage should be controlled so that passivation layer or anti-finger surface is not damaged before installation.
• Cut edge protection and water drainage design should be checked during fabrication because outdoor durability in service is influenced by both the coating and the panel layout.

6.Advantages

• The featured Z120 coating provides a practical metallic protection level for roofing and formed sheet use.
• Minimized spangle gives a more controlled and more uniform galvanized surface appearance than standard coarse spangle finishes.
• The 2.0mm thickness provides higher rigidity than light gauge roofing sheet configurations.
• The 1000mm width and 5800mm length are practical for long panel layouts and fabrication planning.
• Multiple spangle types and surface treatments allow the product to be selected according to visible surface requirement, storage condition, and downstream processing route.

7.How to Choose

• Choose zinc coating level according to the actual service environment. For more demanding outdoor use, a higher coating mass within the listed 40-275 g/m2 range is generally more suitable than a lower level.
• Choose minimized spangle when a more uniform surface is needed for visible applications or when appearance consistency is more important.
• Choose passivated chromated surface for standard storage protection, oiled surface when temporary transport protection is needed, and anti-finger treatment when surface cleanliness and handling appearance are more important.
• Choose thickness according to panel rigidity, support spacing, and forming route. At 2.0mm, the sheet is more suitable for parts that need stronger stiffness than thin roofing gauges.
