Most of the aluminum-magnesium alloy profiles are through the use of primary colors without coating, and some In order to avoid being shoddy, merchants can often use the method of painting the surface of China's recycled aluminum profiles.Therefore, when consumers are purchasing, they should let the merchants provide cross-sections showing the structural profiles of their products to understand the real materials of the students. 2: Listen to the pulley vibration The sliding door has two sets of upper and lower pulleys.
