Baosteel hot-dip galvanized products

The thickness of hot-dip galvanized products ranges from 0.3 to 3.0mm, and the width is from 800 to 1800mm. The types of coatings include pure zinc coating and alloyed coating, and they can be supplied in equal thickness and differential thickness forms. The surface structures of regular products are smooth zinc flower, small zinc flower, zero zinc flower, and zinc-iron alloy. The surface treatment methods include oil coating, chromic acid passivation, chromic acid passivation plus oil coating, environmental-friendly passivation, environmental-friendly passivation plus oil coating, and environmental-friendly anti-fingerprint.
Baosteel’s hot-dip galvanized products are widely used in industries such as automobiles, home appliances, construction, and mechanical manufacturing.
