Shandong Jinghong Intelligent Technology Co. Ltd has specialized in developing and producing high-quality prepainted steel coil, (including PCM metal, PPGI and galvanized steel coil ) for home appliances metal material since 2015. The products are widely used for the outer shell of refrigerators and washing machines, air-conditioners, microwave ovens, water heaters, rice cookers, televisions, and other appearance parts of home appliances.

Mainly products:

Pre-coated metal on GI and GA base is covered with polyester paint material that is baked on its surface
Generally, it is divided into two usages such as home appliance and construction based on workability, durability, and surface treatment.
Excellent workability, chemical resistance, brightness, and good hardness by using "High polymer Polyester" resin paint. So it is good for the outside plate of home appliances which is considered a good-looking exterior view.
Application: Air conditioner, Washing Machine, Refrigerator, Microwave etc.
We provide you with customers wanting patterns and colors from its various buying sources and know-how.

Cold roll production line--- 3 sets
A cold rolled steel coil is produced by pickling a hot coil and rolling it uniformly at an appropriate temperature to a thinner thickness. It has excellent surface configuration and superb mechanical properties for automobile and electronic appliance production.

There are two surface finish-Dull & Bright.
Dull Finish
A dull finish, attained by attaching numerous fine grains onto the steel surface, is often called a "pear-skin finish" or "egg-shell texture".The grains are made by steel grit blasted roll. The dull finish is useful in drawing because lubricant oil can be evenly spread over the entire surface, thereby reducing the possibility of friction.  The fine grains also help boost paint adherence and extend the steel life span of the steel
Bright Finish
The bright finish presents high-quality roughness that is optimal for decorative purposes. The sheet surface is rolled with finely polished rolls.



Galvanized steel production lines-2 sets
GALVANIZED(GI) steel has excellent corrosion resistance, paint ability, and workability due to Zinc's characteristic of self-sacrifice. The base metals in the coil are continuously annealed, galvanized, and properly levelled.
GALVANIZED(GI) steel has a variety of applications not only in engineering and construction but also in automotive and home appliances. Shin Steel Co., Ltd deals with Regular spangles, Minimized spangles and spangles to meet customers' various requests.

It is used for the most widely used PPGI or PPGL for construction materials. This is usually used for the building's exterior panel, construction and interior material. There are some cases in which fluoric resin, silicon resin or PVC resin is used to enlarge corrosion resistance, workability, and anti-pollution depending on usage.
