The surface of the profile should be neat and tidy, and defects such as cracks, peeling, corrosion and air bubbles are not allowed. | ||||||||||||||||||||
| Slight crater, bump and scratch are allowed on the surface of the profile, which allows the depth decorative surface to be no more than 0.03mm, the non-decorative material surface to be no more than 0.07mm, and the mold extrusion mark depth to be no more than 0.03mm. | |||||||||||||||||||||
| The profile ends allow local deformation due to sawing and its longitudinal length should not exceed 20mm. | |||||||||||||||||||||
