Galvalume Steel Coil S250GD
Contrast
| Performance Dimensions | Galvalume Steel Coil S250gd | Ordinary Hot-dip Galvanized Coil (GI) | Advantages |
|---|---|---|---|
| Corrosion resistance | Super strong (2-6 times GI, depending on the environment) | Good | Longer life and extremely low maintenance cost |
| Heat and oxidation resistance | Excellent (up to 315°C for long-term use) | Poor (the coating oxidizes and falls off rapidly at about 200°C) | Suitable for high temperature areas (such as chimneys, ovens) |
| Surface appearance | Unique bright silver-white fish scale pattern/finished surface, more modern | Zinc flower/finished surface | Aesthetics improved, some applications do not require additional painting |
Application
Galvalume steel coil S250gd is mainly used in the construction and home appliance fields. Their characteristics include high corrosion resistance, lightweight advantages and good processing performance.
Building: The surface of the S250GD galvalume sheet is covered with an aluminum-zinc alloy coating, which has better corrosion resistance than ordinary galvanized steel plates. It is suitable for exposed building structures such as roofs and exterior walls, and can extend the service life.
Home appliances: This material is often used in the manufacture of housings for home appliances such as refrigerators and washing machines because of its lightweight (low density) and good formability, taking into account both structural strength and corrosion resistance requirements.
Automobile: S250GD galvalume sheet meets the standards for automotive steel. Its mechanical properties of yield strength ≥250MPa and tensile strength ≥330MPa can meet the load-bearing requirements of body structural parts.
Surface treatment
Conventional surface (C): zinc flower/small zinc flower, standard choice, good economy.
Smooth surface (S): high flatness, no zinc flower, more uniform appearance, conducive to subsequent painting or direct exposure.
Chromic acid passivation (C): Enhance short-term anti-white rust ability, suitable for long transportation and storage period or humid environment.
Chromium-free passivation (E): Environmentally friendly anti-rust treatment, meet the requirements of environmental regulations such as RoHS.
Oil coating (O): Provide additional anti-rust protection during transportation.

Q.
Compared with stainless steel, what is the advantage of galvanized coil S250GD?
A.The core advantage is cost. While meeting the anti-corrosion requirements of many applications, the price of galvanized steel coil S250GD is much lower than that of stainless steel (such as 304). At the same time, it maintains the good strength and processability of steel, making it a very cost-effective choice.
