275G/M2 Regular Spangle 5800mm Galvanised Zinc Sheet Hot Dip Galvanized Sheet

Product Specification

275G/M2 Regular Spangle 5800mm Galvanised Zinc Sheet Hot Dip Galvanized Sheet

1.Product Overview

Hot dipped galvanized steel sheet is used where the steel substrate needs metallic zinc protection before fabrication or installation. This product range is suitable for container plate, building panels, formed sheet parts, and general industrial fabrication where coating mass, thickness range, and surface condition need to be controlled together.

The page is centered on a Z275 configuration with regular spangle appearance. The listed thickness range of 0.15–3.8mm and width range of 1000–1500mm make it suitable for both lighter sheet conversion and heavier fabricated parts. The maximum listed cut length is 5800mm.

2.Technical Solution

This product uses a hot dip galvanizing route in which the steel substrate is coated with zinc to form a sacrificial metallic barrier. In practical use, corrosion behavior depends on zinc coating mass, cut edge exposure, drainage detail, storage condition, and the actual service environment after installation.

The listed zinc coating range is Z40–Z275, with 275g/m2 as the featured upper level on this page. For container plate and other exposed sheet applications, a higher coating mass is generally selected when the environment is more demanding or when longer metallic protection is required before visible red rust develops at exposed areas.

The product also offers several spangle and surface condition options. Regular spangle is the featured appearance here. Chromated, oiled, non-oiled, and skin-pass routes affect storage stability, surface cleanliness, and downstream fabrication behavior, so they should be selected according to the actual processing route rather than appearance alone.

4.Application

This material is suitable for container plate and related fabricated sheet parts where a zinc-coated surface is required before assembly or further processing.

It can also be used for roof and roof components, outside wall panels of civilian and industrial buildings, garage doors, appliance housings, transportation related sheet parts, industrial control cabinets, refrigeration equipment housings, and furniture-related fabricated components.

For outdoor or semi-exposed use, final durability depends not only on coating mass but also on water drainage, overlap design, fastener sealing, and cut edge condition.

5.Processing

• The sheet can be processed by cutting, bending, profiling, punching, and general sheet metal fabrication.
• For container plate conversion, thickness and hardness should be selected together because they affect forming behavior and final shape stability. Soft or medium hardness is more practical for general forming routes, while higher hardness is more relevant when rigidity is the priority and forming severity is lower.
• For visible parts or extended storage, surface treatment should be matched to the handling route. Oiled surface is more suitable for temporary transport protection, while skin pass and non-oiled routes are more relevant where surface cleanliness and dimensional consistency matter.

6.Advantages

• The 0.15–3.8mm thickness range supports both light gauge processing and heavier fabricated sheet applications.
• The Z40–Z275 coating range allows the product to be selected by actual corrosion requirement instead of using one fixed coating level for all projects.
• Regular spangle gives a standard galvanized surface appearance suitable for general industrial and building use.
• The listed widths of 1000mm, 1220mm, 1250mm, and 1500mm are practical for mainstream sheet conversion and fabrication planning.
• Multiple hardness and surface treatment options make the sheet easier to match to different forming, storage, and installation routes.

7.How to Choose

• Choose zinc coating level according to the service environment. For more demanding outdoor or transport-related conditions, a higher coating mass within the listed range is generally more suitable than a lower one.
• Choose thickness according to rigidity and forming route. Thinner gauges are more suitable for easier forming, while thicker gauges are more suitable for stronger fabricated parts and higher stiffness demand.
• Choose regular spangle when a standard galvanized appearance is acceptable. Choose minimized or zero spangle when a more uniform surface is required.
• Choose chromated, oiled, or skin-pass condition according to storage duration, surface cleanliness requirement, and downstream fabrication route.

8.FAQ

Q1. What does Z275 mean for this galvanized steel sheet
Z275 means the zinc coating level is 275g/m2. On this page it is the upper listed coating level and is used where higher metallic protection is required.

Q2. What is the thickness range of this product
The listed thickness range is 0.15–3.8mm.

Q3. What widths are available
The listed widths are 1000mm, 1220mm, 1250mm, and 1500mm.

Q4. What spangle options are available
The listed options are regular spangle, minimized spangle, big spangle, and zero spangle.

Q5. Is this product only for container plate
No. Container plate is the featured application on this page, but the product can also be used for building components, appliance parts, transportation parts, industrial enclosures, and other galvanized fabricated sheet applications.
