Grade 50 SGC490 SGCC SGCD Hot Dipped Galvanized Steel Strip Z60-Z275 for Pipe and Construction Applications

Grade 50 SGC490 SGCC SGCD Hot Dipped Galvanized Steel Strip Z60-Z275 for Pipe and Construction Applications

１．Product Overview

Grade 50 SGC490 SGCC SGCD Hot Dipped Galvanized Steel Strip is produced through a continuous hot-dip galvanizing process that applies a protective zinc coating to carbon steel substrates. The product combines corrosion resistance, formability, and processing flexibility, making it suitable for welded pipes, construction components, appliance parts, packaging materials, and automotive applications.

The available zinc coating range from Z60 to Z275 provides different levels of corrosion protection depending on service conditions and project requirements.

２．Technical Solution

The steel strip is continuously immersed in molten zinc to create a metallurgically bonded coating layer on both sides of the steel substrate. This process provides consistent coating thickness and long-term protection against atmospheric corrosion.

Regular spangle and big spangle finishes are available to satisfy both functional and appearance requirements. Additional surface treatments such as oiling and anti-finger coating can improve storage performance and processing characteristics.

３．Specifications

４．Application

The galvanized steel strip is widely used for greenhouse pipes, gas pipes, heating pipes, roof panels, roof grilles, appliance housings, kitchen equipment, corrosion-resistant automotive components, food storage systems, refrigeration equipment, packaging materials, and transportation containers.

Its corrosion-resistant zinc coating makes it suitable for both indoor and outdoor industrial environments.

５．Processing

The material can be supplied in coil, slit coil, or cut-length form according to customer requirements.

It supports slitting, cutting, roll forming, bending, welding, stamping, profiling, and fabrication processes.

Additional oiling and anti-finger surface treatments can be selected based on storage and processing requirements.
