INTRUCTION
Pre-painted Galanized steel refers that the surface pretreatment of base plate,covering one layer or two layers(more than two layers when nec- essary)organic coating on the surface with the method ofcontinues roller coating;and then conduct drying and solidiying.
Compared with single part spraying or brushing on the surface of forming metal,the costing quality of color-coated stel plate is more uniform, table and ideal.Pre-painted stel plate is chat=racterized of excellent decoration, moldablity corrosion resistance,strong caating adhesive forceand can keep the novel luster for a long time. Since color-coated steel plate has not only mechanical strength and shaping performances of steel plate,but also favorable decoration and corrosion resistance of organc material.It can realize highly effective construction and husband the energy:prewent the pollution caused by second process and other favorable economic benefits.Currenty it has become the ideal composite materia in con struction,household appliance light industry,machinery and electronics and other industries.

STcon modified polyester (SMP),which has good hardness,wear resistance and heatresistance,good external durability and non-powderability.and limited gloss retention and flenibility.The service life is 10-15 years.
High weathering polyester (HDP,excelent U resistance,high durability,and is main properties are between pobyester and fuorocarbon.The service life is 10-12 years.
Polyvinylidene fuoride PVDF)has good formabilityand color retention,excellent outdor durabily and powdering,solvent resistance,and lim- ited color.The service life is 20-25 years
The surface state of color-coated stel shets can be divided into coated sheets,embossed sheets and printed sheets.Color-coated stel sheets are widely used in construction appliances and transportation industies,For the construction industry,thy are mainly used in ste structures,a- ports,warehouses andfreezers.Roof walls and doors for industrial and commercial buildings.
Wide range of uses for color coated steel sheets
Excellent weather resistance,corrosion resistance,high processability and beautiful appearance,with its excellent quality incuding construction interior and exterior materials,household products and electrical appliances,etc.
Product introduction of eolor coated steel
The color cated steel plate is made ofho-dip galvanized steel shet,which is subjected to mulfi-stage degreasing,cleaning and chmical con- wersion treatment,and then the stel strip is continuously coated,cleaned and baked continuously.Color coated steel has eucellentdecorative,an t-corosion,weather resstance,fullcolor,brightcolor can be maintained for more than 15 yearsl.long service lile (30-50 yers),wide use,and has become widely used in the construction industry in the world today.Preferred product.
Main use of color coated steel
Construction ofvils,industrial plants,commercia,residential,warehouse,coldstorage,ship warehouse,interior wall materials,ceiling materials, partitions,fre doors,window panels,signboards,fuel/gas bolers,rice barrels,original building plus layers,etc.It can be fiexibly applied to any building .
Product advantages of color coated steel
Non-poluting.oconomicl:It can reduce investment costs and staf of finshing equipment shorten working hours,improve work and improwe economy.In the future,because of raising awareness of emwironmental protection and strengthening industrisl control color steel plates are more needed.
COLOR DISCRIMINATION MAPS
The substrate of the color costed steel plate is a cold rolled suostrate,a hot-dip galvanized substrate and an electrogalvanized substrate.The coatingtypes can be divided into plyester,silicon modified polyester,poyvinylidene fluoride and plastisolThe surface state of color-costed steel sheets can be divided into coated shets,embossed shets and printed sheets.Color-coated stel shets are widey used in construction appllances and transportation industies.Forthe construction industry,they are mainly used in steel structures,airports,warehouses and freezers.For roofs and dors of industial and commercial buildings,there ae fewer color stel plates for civil building.It differs from plastie stel in the composition of the material.The magnet can be sucked.

FAQ
Q1: What is the difference between HDP and regular PE coating?
A: HDP uses advanced polyester resins with improved UV stabilizers and pigment systems. This provides better color retention and slower chalking compared to standard PE. Expect 20-30% longer service life than PE in equivalent conditions.
Q2: Is HDP suitable for both interior and exterior use?
A: Yes, HDP performs well in both applications. For interiors, expect 15+ year appearance retention. For exteriors, 10-12 years is typical. The UV resistance makes it particularly suitable for south-facing surfaces.
Q3: How does HDP compare to SMP in performance?
A: HDP and SMP offer similar service life (10-12 vs 10-15 years). SMP has better hardness and heat resistance; HDP offers better color stability and UV resistance. Choice depends on specific application requirements and budget.
Q4: What maintenance does HDP coating require?
A: Annual washing with mild detergent maintains appearance. Touch up any scratches promptly. In polluted environments, more frequent cleaning may be needed. HDP's improved UV resistance reduces maintenance compared to PE.
Q5: Can HDP be used for roofing in hot climates?
A: Yes, HDP's UV resistance makes it suitable for hot, sunny climates. Consider light colors for better heat reflection. HDP withstands continuous temperatures up to 80°C, adequate for most roofing applications.
