Product Details

0.85mm*1250mm HDP Corrosion Resistance Pollution Prevention

Textured Matt Prepainted Steel Coil S320GD Nippon,Akzonobel

 
HDP Highly Durable Polyester Coating
 
HDP high durability color coated plate adopts HDP polyester coating, which has excellent durability, high molecular weight resin, less polymer branching chain, stable binding energy, and resistance to photodegradation, so it is hard to chalk and high gloss level is not reduced.
 
HDP color steel plate adopts inorganic ceramic pigments, and is not easily faded by sunlight.
 
The most important performance of high weather resistant polyresin is its high weather resistance and strong corrosion resistance, and it is mainly used in areas with long sunshine hours, high dryness, or large day/night temperature differences and more severe humidity.
 
The range of use is wide. Color coated sheets and coils belong to the high-end products. Coating thickness is generally 5UM epoxy resin primer + 20UM HDP polyester topcoat on the front side and 5UM epoxy resin primer + 6UM PE resin topcoat on the back side.

 

Technical Details

  • Rich, deep, appealing visual appearance.
  • Unique textured finish reduces the appearance of oil-canning.
  • Enhanced durability. More scratch-resistant finish.
  • Standard 35-year finish warranty.
  • Stocked in thirteen (13) colors.
  • Available in all CMG standard colors.

Substrate Type

1. Hot-dip galvanized steel sheet: this substrate has good impact performance and good elongation and yield value, this kind of production of color steel sheet in the construction, decoration, and other industry applications get very good evaluation.

2. hot-dip aluminum-zinc-plated steel sheet: the process of this substrate and hot-dip galvanized steel sheet process is basically similar, the difference lies in the surface of the zinc layer content is not the same, the surface of the zinc flower phenomenon is also a big difference, other aspects of the basic there is no gap, weather resistance and life is better than galvanized steel.

3: Aluminum: the best advantage of aluminum is the special industry with, because the price itself is very high in so on the cost alone is also a small expenditure, so only special industry options: refrigeration, insulation, poisoning, sterilization, and so on industry. Impact performance: excellent, can be tangible, intangible impact, bending.

4. Cold rolled sheet: cold rolled sheet is not annealed steel, but also galvanized steel, aluminum zinc-plated steel predecessor. This steel plate impact performance is very low, the material hardness is very high, the yield value as well as the elongation is very low, welding performance is good.
