The color-coated steel plate is an organic composite material. It is a cold-rolled high-strength zinc steel plate. After a series of treatments, the organic coating is baked. The coating surface is uniform, stable in quality, and durable.
Changsha Zhongyang Company adopts TSTE28 (TS280GD) and TSTE34 structural special steel plates or foreign imported high-strength color steel plates produced by Shanghai Baosteel Corporation. Its technical performance is as follows:
(1) Yield strength of substrate >280Mpa or 340Mpa
(2) The amount of zinc plating> 180g/m2-275g/m2
(3) Coating thickness > 23um
(4) Salt spray resistance> 500h
Thickness Coated steel plate thickness: 0.8-1.4mm
Color The color coated steel plate can be seen in standard color samples or in actual samples.
1. Upper coating: TOP FINISH COATING
2. Chemical coating: Zinc PHOSPHATE COAING
3, under the coating: Primary coating (PRIMER COATING)
4. Zinc layer: ZING COATING
5, cold rolled steel: base metal / cold rolled steel (BASE METAL/COLD ROLLED STEEL SHEET)
