Zinc Coating Jis G3302 Hot Dipped Galvanized Steel Sheet Flat Galvanized Sheet Metal

Zinc Coating Jis G3302 Hot Dipped Galvanized Steel Sheet Flat Galvanized Sheet Metal

1.Product Overview

Hot dipped galvanized steel sheet is used where the steel substrate needs zinc protection before forming, installation, or further fabrication. This product range is suitable for pipe making, building components, and general industrial sheet processing where coating level, surface condition, and dimensional stability need to be considered together.

The listed range covers 0.15–3.8mm thickness and widths from 1000mm to 1500mm. That makes it suitable for both lighter formed sheet parts and thicker fabricated components. JIS G3302 positioning also makes it relevant for buyers who need a commonly specified galvanized sheet route for construction and industrial use.

2.Technical Solution

This product uses a hot dip galvanizing process, where the steel sheet is coated with zinc to create a protective metallic barrier between the steel substrate and the service environment. In practical use, corrosion behavior depends on zinc coating mass, cut-edge exposure, storage condition, drainage detail, and the actual operating environment after installation.

The page lists zinc coating at 40–275g/m2 in the main product section, together with multiple spangle options and several surface treatment routes. Surface treatment is not only a storage feature. Chromated, oiled, and anti-finger options affect short-term handling, surface cleanliness, and fabrication condition before the product goes into final use.

4.Application

This material is suitable for pipe making, roof and roof components, outside wall components, garage doors, and window blind related sheet parts.

It can also be used in household appliance housings, transportation related parts, industrial control cabinets, refrigeration equipment housings, vending machine panels, and furniture related fabrication where zinc-coated steel is required before final assembly.

For pipe production, the final forming route, bend severity, and storage condition should be checked together with coating level and thickness.

5.Processing

• The sheet can be processed by cutting, slitting, bending, profiling, punching, and general sheet metal fabrication.
• For pipe making, thickness and hardness should be selected together because they influence forming behavior and final shape stability. For visible parts, spangle type and surface treatment should be selected in advance because they affect final appearance and handling marks.
• When the product is used outdoors, storage and installation should avoid trapped water at overlaps, joints, or cut edges.

6.Advantages

• The 0.15–3.8mm thickness range supports both lighter sheet conversion and heavier fabricated parts.
• The 1000mm to 1500mm width range fits common flat sheet processing and industrial fabrication routes.
• Multiple spangle options allow the surface to be matched to visible-face requirements and downstream finishing needs.
• Chromated, oiled, and anti-finger options give more flexibility for storage, transport, and fabrication handling.
• The listed hardness range makes the product more adaptable to different forming routes instead of one fixed temper condition.

7.How to Choose

• Choose zinc coating level according to the actual service environment. Lower coating levels may be acceptable for lighter indoor or controlled conditions, while higher coating levels are generally more suitable for more demanding exposure.
• Choose zero or minimized spangle when surface uniformity is more important. Choose regular or big spangle when conventional galvanized appearance is acceptable or preferred.
• Choose chromated 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. Thinner gauges are more suitable for easier forming, while thicker gauges are more suitable for stronger fabricated parts.
