The two are different in nature.
Color steel plate is a color coated steel plate, and color coated steel plate is a steel plate with an organic coating. Hot galvanized sheet is a steel plate with a layer of zinc on the surface. Galvanizing is an economical and effective method to prevent rust.
The two have different characteristics.
Color steel plate: Light weight: 10-14 kg square meters, equivalent to 1/30 of the brick wall; Heat insulation: thermal conductivity of core material: λ≤=0.041w/mk; High strength: can be used as ceiling envelope plate bearing, bending and compressive resistance; General houses do not use beams and columns; Bright color: no need for surface decoration, color galvanized steel anticorrosion layer retention period of 10-15 years.
Hot galvanized sheet: Galvanized sheet should have a good appearance, no defects harmful to the use of the product, such as no plating, holes, cracks and scum, more than thick plating, abrasion, chromic acid dirt, white rust, etc. Foreign standards are not very clear about the specific appearance defects. Some specific defects should be specified in the contract when ordering.
Other differences
Galvanized sheet is the raw material of color steel plate, cold galvanized to make the color coating roll easy to rust, but hot galvanizing will not, cold galvanized is not plated color coating roll easy to rust, galvanized is a silver-gray substrate, but the color coating is painted on this, all kinds of colors can be, so called color coating.
