Product Overview
SMP coating bridges the gap between economical PE and premium PVDF, offering enhanced durability at moderate cost. The silicone modification improves hardness, abrasion resistance, and heat tolerance compared to standard polyester. Ideal for high-traffic commercial buildings where appearance matters but budget constraints exist.

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.

Product Description
The substrate of the color coated steel sheet is a cold rolled substrate,a hot-dipgalvanized substrate and an electrogakanized substrate,and the substrate of the colored aluminum plate is an akuminum plate.
The types of coatings ean be divided into:
Polyester (PE)has good adhesian,a wide range of formaility and outdor durability and moderate chemical resistance.The servic ife is 7-10 years.
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. Superior Durability and Weather Resistance ,Aesthetics and Flexible Customization,Outstanding Economic Benefits,In the future,because of raising awareness of emwiro nmental 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: How does SMP compare to PE and PVDF coatings?
A: SMP offers middle-ground performance: better than PE (hardness, heat resistance, gloss retention) but not as premium as PVDF (UV resistance, longevity). Cost is 20-30% more than PE, 30-40% less than PVDF. Good choice for 10-15 year applications.
Q2: What environments suit SMP coating best?
A: SMP excels in industrial and commercial environments with moderate pollution and UV exposure. Good for warehouses, factories, and commercial buildings. Not recommended for severe marine or heavy industrial pollution without more frequent maintenance.
Q3: Can SMP coating withstand pressure washing?
A: Yes, SMP's improved hardness resists pressure washing better than PE. Use moderate pressure (under 100 bar) and keep nozzle at least 30cm from surface. Avoid abrasive cleaners that may scratch coating.
Q4: What is the chalking resistance of SMP?
A: SMP shows significantly less chalking than PE after 5-10 years exposure. While some chalking occurs (normal aging), it progresses slower and is less severe than with standard polyester coatings.
Q5: Is SMP available in metallic colors?
A: Yes, SMP accepts metallic and mica effect pigments well. These finishes maintain appearance longer than with PE coating due to SMP's superior gloss retention. Metallic SMP is popular for commercial building applications.
