50 Ksi Dx51d 20 Gauge Hot Dipped Galvanized Steel Sheet No Spangle

1.Product Overview

Hot dipped galvanized steel sheet is used where the steel substrate needs zinc protection before forming, fabrication, or installation. This product range is suitable for pipe making, industrial panels, and general building sheet applications where coating mass, thickness, and surface condition need to be matched to the actual processing route.

This page is centered on a featured 0.25mm G60 configuration with zero spangle positioning. Compared with regular visible spangle material, zero spangle is more suitable when a more uniform surface is required for forming, visible parts, or downstream finishing control.

2.Technical Solution

The product uses a hot dip galvanizing process in which zinc forms a metallic barrier over the steel substrate. In practical use, corrosion performance depends on zinc coating mass, cut-edge exposure, drainage condition, storage method, and the final service environment.

The detailed listing shows a zinc coating range of 30-275g/m2, with 60g/m2 as the featured coating on this page. Thickness range extends from 0.13mm to 5.0mm, while the popular processing range is 0.14-2.0mm. That means the product can be selected both for light gauge forming and for heavier fabricated parts.

Surface condition also affects fabrication behavior. Chromed, skin pass, oiled, slightly oiled, and dry options are listed, and these influence storage stability, surface cleanliness, and forming consistency before the sheet enters the final production route.

3.Specifications

4.Application

• This material is suitable for making pipes where a zinc-coated steel sheet is required before roll forming or fabrication.
• It can also be used for industrial panels, building sheets, roof and wall components, appliance housings, transportation related parts, industrial control cabinets, refrigeration equipment housings, and furniture related fabrication.
• For pipe and profile production, the final result depends on coating level, sheet thickness, bend severity, and the storage condition after forming.

5.Processing

• The sheet or coil can be processed by slitting, cut-to-length, bending, profiling, punching, and general sheet metal fabrication.
• For pipe making, thickness and surface condition should be selected together because they affect forming stability, weld area behavior, and handling condition during production.
• When visible surfaces matter, zero spangle and the selected surface treatment should be confirmed before production because they affect appearance consistency and post-forming surface control.

6.Advantages

• The 0.25mm featured thickness is suitable for light gauge pipe and sheet forming routes.
• The detailed thickness range of 0.13-5.0mm provides flexibility for both thinner forming gauges and thicker fabricated parts.
• The zinc coating range of 30-275g/m2 allows the product to be selected according to actual corrosion requirement instead of using one fixed coating level for all projects.
• Zero spangle offers a more uniform surface appearance than standard regular spangle material.
• Multiple surface conditions make the product easier to match to storage, handling, and downstream fabrication needs.

7.How to Choose

• Choose zinc coating level according to the service environment. Lower coating levels may be acceptable for lighter indoor or controlled conditions, while higher coating levels within the listed range are more suitable for more demanding exposure.
• Choose thickness according to the forming route. Thin gauges are more suitable for lighter pipe and panel conversion, while thicker gauges are more suitable for stronger fabricated parts and higher stiffness requirements.
• Choose zero spangle when surface uniformity is more important than conventional galvanized appearance.
• Choose chromed, skin pass, oiled, slightly oiled, or dry condition according to storage duration, surface cleanliness requirement, and downstream processing method.
