Galvanized Vs Galvalume

Galvanized Vs Galvalume

Corrosion Resistance

The corrosion of galvanized steel is 6 to 8 times that of galvanized steel, especially in the environment of acid rain, it can guarantee no rust for 20 years.

1. Edge-cutting protection: Aluminized zinc plate has a good protective effect on cutting edges. The life of standard weight of aluminum-zinc plate is 3-4 times that of galvanized plate.
2. Atmospheric corrosion resistance: In the harsh marine environment, rural and industrial environment, the corrosion resistance of galvanized steel is better than that of galvanized steel.
3. Adaptability to humidity: The Cleveland condensation experiment shows that the humidity and corrosion resistance of galvanized steel sheet is 5-6 times stronger than that of galvanized steel sheet.
4. Water resistance: The aluminum-zinc plate has excellent water resistance and is more corrosion-resistant than ordinary galvanized plates.Heat-resistance
5. Heat resistance: The heat resistance of galvanized steel is far better than that of galvanized steel.The galvanized steel sheet can withstand the high temperature of 67 7 ℃, and often works at 3 15 ℃ without discoloration, and its heat resistance is better than that of the galvanized steel sheet.

Formability

The galvanized sheet has the characteristics of being very easy to be fixed and rotated, and does not require more complicated forming equipment.

Heat Reflectivity

The heat reflectivity of the galvanized steel sheet is almost twice that of the galvanized steel sheet. Therefore, it can also achieve energy-saving effects as a roof and panel when it is not painted.

Solderability

Compared with galvanized steel, galvanized steel is less fume and safer than galvanized steel, and it is not easy to produce pores. It can be compared with aluminum plate in terms of welding speed.

Paintability

Due to the excellent adhesion between the zinc layer of the galvanized steel sheet and the unpainted, it can be painted without pretreatment and weathering when used as a signboard or for general purposes: while galvanized steel needs weathering and pretreatment. deal with.
