1.Corrosion of weather resistant steel solder joints: the oxidation speed of the solder joints should be the same as the main body of the weather resistant steel material, so attention should be paid to selecting special electrodes with similar chemical composition and strength and toughness to the weather resistant steel.
2.Corrosion of weathering materials in stagnant water environment: weather resistant steel is not rust-free. If there is water in the low recesses of the environment where weather resistant steel is located, it will cause the corrosion rate of weather resistant steel to become faster, so it is necessary to pay attention to it during construction. Drain the water well, and install the finished product made of weather-resistant materials in a place where no water will accumulate.
3.Construction temperature of weather resistant steel: The surface temperature of weather resistant steel material exceeds 45℃ and is lower than 0℃, and strong high temperature continuous exposure will affect the rusting effect of weathering material. Try to avoid construction under the above conditions.
