Combined sound barrier of two materials, galvanized sheet and color steel sheet

This project uses a combination of two types of materials, a galvanized sheet and a color steel sheet. The overall height is three meters high, and the one-meter curved perforated sound-absorbing panel at the top can effectively control the sound diffraction through the upper part of the screen; two meters below All are white colored steel plates, H-shaped steel columns 100 * 100, and the surface is electrostatic sprayed, with good anti-corrosion performance and a service life of more than 15 years!
