Regular Spangle Hot Dipped Galvanized Steel Sheet 0.12mm - 4.0mm

1.Product Overview

Hot dipped galvanized steel sheet is used where the steel substrate needs a metallic zinc coating for corrosion protection before fabrication or installation. This product range is suitable for construction panels, roofing components, structural parts, machinery housings, and electrical applications where thickness range, coating mass, and surface appearance need to be matched to the service environment.

The page covers 0.12mm to 4.0mm thickness, 600mm to 1500mm width, and 1000mm to 5800mm length. That range makes it suitable for both light gauge sheet processing and heavier fabricated parts. The zinc coating range of 40–275g/m2 is the main technical variable for corrosion protection, while spangle selection affects surface appearance and downstream paint or visible-face requirements.

2.Technical Solution

This product uses a hot dip galvanizing process, where the steel sheet is coated with zinc to form a barrier layer between the steel substrate and the external environment. In actual use, corrosion performance depends on the zinc coating mass, cut edge exposure, storage condition, drainage design, and whether the sheet is used indoors or outdoors.

The listed coating range is 40–275g/m2. Lower coating mass is more suitable for lighter indoor or controlled environments, while higher coating mass is more suitable for exterior and more demanding service conditions. Thickness also affects application boundary. Thin gauges are more suitable for forming and panel work, while thicker gauges are more suitable for structural fabrication and higher rigidity requirements.

Spangle options include regular, zero, and big. Regular spangle is commonly selected when a conventional galvanized appearance is acceptable. Zero spangle is generally more suitable where surface uniformity is more important. Big spangle is mainly an appearance selection rather than a load or corrosion variable.

3.Specifications

4.Application

• This material is suitable for construction, automobile, machinery, and electrical applications.
• In building use, it can be used for roofing sheets, wall cladding, light structural parts, duct and enclosure fabrication, and general galvanized sheet components.
• In industrial use, it can be used for formed sheet parts, housings, guards, and fabricated components where metallic coating protection is required before painting or direct use.

5.Processing

• The sheet can be supplied in cut length or coil form depending on the fabrication route.
• It is suitable for cutting, bending, roll forming, profiling, punching, and general sheet metal fabrication. For visible surface applications, spangle type should be selected before production because it affects final appearance. For fabricated parts with exposed edges, handling, storage, and installation details should be controlled because corrosion behavior at cut edges is influenced by service condition rather than coating mass alone.
• For heavier gauges closer to 4.0mm, forming equipment capacity and bend radius should be checked before production planning.

6.Advantages

• The 0.12mm–4.0mm range gives wider processing flexibility than products limited to light gauge sheet only.
• The 40–275g/m2 zinc coating range allows the material to be selected by actual corrosion requirement instead of using one fixed coating level for all projects.
• The 600mm–1500mm width range fits common panel, strip, and fabrication routes.
• Regular, zero, and big spangle options allow the surface to be matched to visible-face and downstream finishing requirements.
• Coil ID of 508mm or 610mm and coil weight of 3–8 tons fit standard coil handling and slitting routes in many fabrication lines.

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 use or more demanding environments, a higher coating level within the listed range is more suitable.
• Choose thickness according to rigidity and forming route. Thin gauges are more suitable for roll forming and light panels. Thicker gauges are more suitable for parts that need more stiffness or structural support.
• Choose regular spangle when a standard galvanized appearance is acceptable. Choose zero spangle when a more uniform visible surface is required. Choose big spangle only when that appearance is intentionally specified.
• Choose width and length according to final blank layout, transport condition, and fabrication equipment.
