Product Details

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.

Our after-sale Service

Our Product Services

Cut large coils into small coils or Strip.
For steel coils, we can cut one large steel coil into small steel coils for loading at seaport; because for container shipping, each container usually loads weight can not be over 26 tons, but each large coil is usually about 28 tons, so one large coils has to be cut into small coils, and because the forklift usually takes 7-10 tons at seaport, so for easy loading into conatiner, each large steel coil usually is cut into 3 small coils. For bulk vessel shipping, it usually demands coils weight under 18 tons, so most times, also need cut one large coil into 2 small coils.
Open flat coils into steel plate.
For final application, need open flat the coils and cut the coils into steel plate, so we open flat the coils and cut the coils to steel plate to the sizes as required. For saving cost for loading by container, load into 20 feet containers, so cut the length under 5800mm, usually as required to cut to length 2440mm and 5800mm, width usually be 1220mm and 1500mm.after cutting the steel coils into steel plate, we can do black paints on the surface of the plate to make the plate to be anti-rust.
