EN10147 SGCH Hot Dipped Galvanized Steel Strip 0.62mm × 130mm Z275 for Car Ceiling and Heat Shield Applications

１．Product Overview

EN10147 hot dipped galvanized steel strip is manufactured using SGCH high-strength steel substrate with a Z275 zinc coating. The combination of high coating weight and galvanized protection provides reliable corrosion resistance for automotive, appliance, construction, and industrial applications.

The 0.62mm × 130mm strip specification is suitable for automotive ceiling components, heat shields, structural profiles, appliance parts, and fabricated products requiring durability and long service life.

２．Technical Solution

The steel strip is continuously immersed in a molten zinc bath to create a metallurgically bonded galvanized coating. The zinc layer provides sacrificial protection against corrosion and extends service life in demanding environments.

The SGCH substrate offers higher strength characteristics, while the Z275 coating improves resistance to moisture, oxidation, and atmospheric corrosion. Surface treatments such as chromating, skin pass, passivation, and oiling can be supplied according to processing requirements.

３．Specifications

４．Application

This galvanized steel strip is widely used for automotive ceiling panels, heat shields, greenhouse pipes, gas pipes, heating pipes, roof panels, roof grilles, home appliance housings, kitchen equipment, refrigeration systems, structural profiles, storage equipment, and packaging materials.

The high zinc coating makes it suitable for applications requiring enhanced corrosion resistance.

５．Processing

The material can be processed by slitting, cutting, roll forming, bending, profiling, stamping, punching, welding, and deep drawing operations.

It can also be used as a base material for color coating, PPGI production, corrugated roofing sheets, and building exterior applications.

６．Advantages

• Z275 zinc coating provides enhanced corrosion protection for long-term service.
• SGCH substrate delivers higher strength for structural and automotive applications.
• Regular spangle finish provides a consistent galvanized appearance.
• Multiple surface treatment options support different fabrication requirements.
• Suitable for both industrial processing and construction applications.
• 508mm coil ID is compatible with common slitting and roll-forming equipment.

７．How to Choose

• Choose Z275 coating when long-term corrosion resistance is required.
• Select SGCH grade for applications requiring higher strength and wear resistance.
• Confirm strip width and thickness according to production equipment and component design.
• Use chromated or passivated surfaces when storage and transportation protection are important.
• Consider oiling treatment when additional temporary rust protection is needed.
