Key Attributes
- Excellent corrosion resistance: The hot-dip galvanized coating is thick (30-50 micrometers) and metallurgically bonded to the steel. It can last more than 50 years in suburban areas and up to 20 years in urban or offshore environments.
- Durable and reliable: The coating has strong adhesion, can withstand bumps during transportation and installation, and is not easy to peel off.
- Comprehensive protection: The galvanizing process can cover hidden areas such as corners and recesses of angle steel, achieving all-round protection.
- Time and cost efficient: Compared with painting, the overall cost of galvanized anti-corrosion treatment is lower. It is formed in one go at the factory, eliminating the trouble of on-site painting.
Main Applications
Due to its excellent anti-corrosion and load-bearing properties, it is widely used for structural support in outdoor or humid environments:
- Electric power and communication engineering: Such as power transmission and transformation iron towers, communication towers, and substation supports (some projects have a corrosion rate of less than 0.5% at -40℃).
- Building steel structures: Factory frames, curtain wall keels, shelves, etc.
- Transportation facilities: Highway guardrails, bridge components, street lamp poles, etc.
- Shipbuilding and light industry: Marine components, mechanical equipment supports, etc.
