1. Phosphated drywall screws are the most basic product line, and galvanized drywall screws are a supplement. The scope of application and purchase price of the two are basically the same. The slight difference is that black phosphating has a certain degree of lubricity, and the attack speed is slightly better (the speed of tapping to the specified thickness of the steel plate is the quality assessment index); while the galvanizing is slightly better in anti-rust effect, and the natural color of the product is lighter. , It is not easy to fade after painting.
