3 Classification and model
Color coated steel sheets and strips
Test methods for color coated steel sheets and strips 3.1 Colored profiles are divided into casement series (P) and sliding series (T) according to their use. 3.2 The model of the product consists of the name code, characteristic code, main parameter code, and modification serial number. [CB
Retrofit serial number (in the order of capital Chinese pinyin A, B, C)-profile serial number
Plate thickness
-series number
Classification number (P, T)
Name code
Profile serial number is the profile serial number. For example: the plate thickness of 01, 02, 101, 153 is the color plate thickness required for rolled profiles. For example: 0.7mm.0.8mm and other series are the series numbers of color plate doors and windows. For example, 46 series, 68 series, etc. Main parameter code
Characteristic code
Marking example: Casement 46 series, plate thickness of 0.8mm, serial number 153 color plate profile. Marked as: CB-P46-0.8-153
