Brief Introduction:
1. Prepainted Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.
2. The base metals for Prepainted Steel Coil consist of cold rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of Prepainted Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.
3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.
Advantages:
1) Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted Galvanizeed Steel Sheet.
2) High heat resistance: The reflective surface of the material aids in efficiently reflecting the sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity converts into energy savings.
3) Aesthetics: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple sizes as per the requirements that given by our customers.
4) Versatility: can be used in the various areas.
Application:
1. Construction:(Outside) workshop, agricultural warehouse, residential precast unit, corrugated roof, wall, rainwater drainage pipe, terrace, retailer booth, roller shutter door(Inside) door, door case, light steel roof structure, folding screen, ceiling, elevator, stairway, vent gutter
2. Electrical appliance: refrigerator, washer, switch cabinet, instrument cabinet, air conditioning, micro-wave oven, bread maker
3. Furniture: central heating slice, lampshade, chifforobe, desk, bed, locker, bookshelf
4. Carrying trade: exterior decoration of auto and train, clapboard, container, isolation lairage, isolation board
5. Others: writing panel, garbage can, billboard, timekeeper, typewriter, instrument panel, weight sensor, photographic equipment
