The glass hanging bar is made of seamless steel tube with diameter 146mm. According different glass length which from 2000mm to 3660mm, the glass hanging bar is designed by 3D. To make the welding fine, we use the carbon dioxide welder. Through processing by epoxy paint, the hanging bar surface is corrosion resistant and rust resistant, no damage to the glass sling. The clear marks on each site for lifting sling makes it convenient to operate.
