Our products use the latest polyester paint, Top side coating is used double roll baking production technology. The substrate sheet is promoted to Zin120g, the thickness of the film is 22/8 m, which great Ly enhances the corrosion resistance, weather resistance and color retention of the pre-painted sheet. NAIMEI products series can use for15-20 years under the condition of direct exposure. Its good weather resistance and machining performance could fully meet the requirements of general building panels.
Suggested Proposed Use
It is Suitable for general buildings, commercial buildings, outdoor house. Such as roof, cladding, etc.
Attention
The substrate sheet is better than aluminum zinc sheet. But it is not recommended for use in very bad environments. Such as the serious pollution of industrial enterprises or coastal erosion serious area, It is suggested to use our CHAOMEI color sheet (PVDF fluorocarbon series).
Product Size
Z120 PE22/8
Basic Material
NAIMEI pre-painted sheet substrate production use Sino Master hot dip galvanized steel coil, the thickness and tolerance can meet customer demand. Surface quality is according to the home appliance base board, with good smoothness and good adhesion.
Coating Technology
Using two roasting roller coating curing process.
Coating Technology
Passivation treatment is used the Henkel surface treatment to make film on surface of coating, which is with good corrosion resistance and paint adhesion.
Transport Requirement
Transport vehicles should be clean, and Use professional lifting tools, pay attention to shake, indentation, pollution prevention, collision, preventing the sliding.
Store Requirement
The storage environment of Steel roll and products should ensure that not in outdoor and changeable temperature, storage area should be flat, and has enough bearing capacity, at the same time should avoid the multi-layer stacking haulms and products with big external force.
Used Request
Because of the influence of the long-time, the physical and chemical properties of steel will change with the extension of storage time, lead to formability and coating will change accordingly, in order to avoid bad effect, It is suggested that user to use as early as possible.
