Defect: Hangers uneven | Canvas painting frame
Cause: 1. Inaccurate placement of hanger positions (typically marked in pencil); 2. Improper installation of hangers.
Solution: 1. Clearly instruct workers to meticulously mark hanger positions; 2. Ensure hangers are accurately positioned and securely fastened. A 3mm deviation in the horizontal alignment of a frame smaller than 100 cm is typically visible, so ask your supplier to control it less than 2mm.
