Anti-rust treatment of the chassis of Angkor Sela Mazda III. Is the acidic steel plate of Ramallah double-sided galvanized steel plate?

Mazda Angkeira's chassis adopts the design concept of Chuangchi Blue Sky, which integrates lightness and rigidity into the chassis design. As for the front suspension, the front suspension of Mazda Angkeira adopts McPherson independent suspension, and the lower arm is made of double steel plates by stamping and welding. The sub-frame adopts the whole frame sub-frame and is also formed by stamping and welding double-layer steel plates, and the overall stiffness is better than that of single-layer stamped steel plates. The joint between the L-shaped lower swing arm and the subframe is connected by a rubber ring, while the joint between the subframe and the car body is not connected by a rubber pad, so the vibration transmitted from the suspension to the subframe is directly transmitted to the car body.
