SGCC DX51D And Q195 0.15mm Thin Galvanized Steel 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 building panels, roofing components, outer wall sheets, appliance housings, and general sheet metal fabrication where corrosion resistance, thickness, and surface condition need to be selected together.

The listed range covers 0.15–3.8mm thickness and widths from 1000mm to 1500mm. That makes it suitable for both thin gauge processing and heavier fabricated parts. The product is positioned around SGCC and DX51D grade routes commonly used for galvanized sheet applications.

2.Technical Solution

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

The listed zinc coating range is Z40–Z275. Lower coating levels are generally used for lighter or more controlled service conditions, while higher coating levels are more suitable for more demanding environments. The page also lists regular, minimized, big, and zero spangle options, together with chromated, oiled, and skin pass related surface conditions, which affect appearance, storage stability, and downstream handling.

3.Specifications

4.Application

This material is suitable for roof and roof components, outside walls of civilian and industrial buildings, garage doors, and window blinds.

It can also be used in household appliance housings, transportation related sheet parts, industrial control cabinets, refrigeration equipment housings, vending machine panels, and furniture related fabrication where galvanized surface protection is required before final assembly.

For building use, final durability depends not only on zinc coating mass but also on profile design, overlap condition, drainage, and actual exposure environment.

5.Processing

• The sheet can be used for cutting, bending, profiling, punching, and general sheet metal fabrication.
• For thin gauge applications such as 0.15mm material, forming route, support spacing, and handling condition should be checked together because very light gauges respond more strongly to bending radius, transport handling, and installation flatness.
• For visible applications, spangle type and surface treatment should be selected before production because they affect final appearance and short-term storage behavior.

6.Advantages

• The 0.15–3.8mm thickness range supports both thin sheet conversion and heavier fabricated sheet applications.
• The Z40–Z275 coating range allows the material to be selected according to actual corrosion requirement instead of using one fixed coating level for all projects.
• Multiple spangle options allow the sheet to be matched to different visible surface requirements.
• Chromated, oiled, and skin pass related surface conditions give more flexibility for storage, transport, and fabrication routes.
• The listed standard widths are practical for mainstream building and industrial sheet processing.

7.How to Choose

• Choose zinc coating level according to the service environment. For protected indoor or lighter conditions, lower coating levels may be acceptable. For outdoor or more demanding use, higher coating levels within the listed range are generally more suitable.
• Choose thickness according to rigidity and forming route. Thin gauges are more suitable for lightweight formed parts. Thicker gauges are more suitable for stronger fabricated components and higher stiffness requirements.
• Choose minimized or zero spangle when surface uniformity is more important. Choose regular or big spangle when conventional galvanized appearance is acceptable.
• Choose chromated, oiled, or skin pass condition according to storage duration, handling requirement, and downstream processing route.
