Galvanized Steel I Steel Product Introduction
Galvanized I-beam refers to a profile that is galvanized on the surface of ordinary I-beam. The galvanized layer can effectively prevent the I-beam from rusting, extend its service life, and has good corrosion resistance, especially suitable for humid and corrosive environments.

Galvanized Steel I Steel is widely used in
- Outdoor building steel structure frame
- Power transmission tower and substation structure
- Highway guardrail support system
- Port terminal facilities
- Agricultural greenhouse frame
- Industrial equipment support platform
Galvanized I-beams are better than ordinary I-beams in several aspects
More corrosion resistant:
The main function of the galvanized layer is to protect the steel. Zinc has a higher corrosion resistance than iron and steel. Therefore, the galvanized layer can corrode before the steel itself, thereby protecting the steel from corrosion. Even if the galvanized layer is damaged, the sacrificial anode effect of zinc can continue to protect the steel.
Longer service life:
Since galvanized I-beams have better corrosion resistance, they have a longer service life in corrosive environments such as moisture, acid and alkali, which can reduce the cost of repair and replacement.
Lower maintenance cost:
Since the galvanized layer has a good protective effect, the later maintenance of galvanized I-beams is relatively simple, which can save maintenance costs.
Aesthetics:
The galvanized layer is usually silvery white and has a certain aesthetics, which can meet some occasions that require appearance.
