How to Store PPGI Steel ?

1. What is Color Coated Galvanized Steel Coil

Color-coated galvanized steel coil is also called color steel coil. Color-coated steel coils are made of cold-rolled steel and galvanized steel coils as substrates, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), color coating in a continuous manner (roller coating method), baking and cooling finished product. It is made of metal coils (cold-rolled steel, hot-dip galvanized steel coil , aluminum-plated steel, high aluminum alloy steel, etc.) as the base material, and various organic coatings or plastic films are coated or laminated on the surface. Color-coated steel sheets are widely used in construction, home appliances, and transportation.

2. PPGI Steel Specification

2.1 Strong Weather Resitance

The color-coated galvanized products of Jianhui Factory use the famous AKzonobel paint, which can withstand the test of various harsh weather conditions and is not easily eroded by factors such as oxidation, corrosion and sunlight. The PE, HDP, SMP, PVDF steel paint coating on its surface can effectively resist ultraviolet rays, acid rain and corrosive gases, and keep the color-coated galvanized products bright in color and full of luster.

2.2 Good Corrosion Resistance

The galvanized layer provides excellent corrosion resistance for color-coated panels. Through the galvanizing process, the contact between the steel and the external environment is effectively isolated, the service life is extended, and the corrosion resistance is improved.

2.3 Rich Colors

Color-coated galvanized steel can be customized according to customer needs, providing a variety of color options. Bright red, blue, or steady gray, green, etc., meet the design requirements of different fields and have more application possibilities.

2.4 Convenient Construction

The color-coated galvanized sheet is light in weight, easy to cut and bend, and the construction is convenient and fast. The surface coating is smooth and uniform, suitable for various shapes and sizes, and widely used in the fields of construction and decoration.

2.5.Environmentally Friendly and Sustainable

color-coated galvanized steel coils meet environmental protection requirements. It can be recycled and reused, which is in line with the concept of sustainable development.

3.Jianhui PPGI steel coil factory has a lot of customer’s love and welcome 

Color coated galvanized steel coils is a special colour coated steel , which has the characteristics of anti-corrosion, weather resistance and strong decoration. Most importantly ,Color coated galvanized steel coils storage, transportation, loading and unloading are important links that affect the quality of color coated steel coil .  In order to ensure the quality of color-coated steel coils and prolong their service life, correct storage is very important. The following are some suggestion from Jianhui Steel Manufacturers for all customers to store color-coated galvanized steel coil.

3.1 Environmental conditions for steel storage

Color coated steel coils should be stored in a dry and ventilated indoor environment, avoiding storage in the open air and places with large temperature changes. Avoid direct sunlight and humid environment. To prevent corrosion and steel painting damage. In addition, avoid the erosion of various corrosive substances.

3.2 Selecting the right steel storage location

The storage location of PPGI steel plates and PPGI coils should be reasonably arranged to facilitate access and minimize unnecessary movement.

3.3 Protecting the PPGI Steel Coil Surface

The surface of the color coated steel coil is easily scratched and damaged, so special care should be taken to protect it during storage and handling. Jianhui Steel recommends using materials such as plastic film or cardboard to wrap the steel plate to prevent scratches on the steel surface.

 3.4 PPGI Steel Coil Stacking Height

Avoid stacking too high, PPGI  steel coil should avoid too high when stacking to prevent deformation and damage. The stacking height should not exceed 3-4 layers in general, and each layer should be isolated by using wooden boards or bedding materials.

 3.5 Protect PPGI Steel Surface

The surface of PPGI steel coil is easily scratched and damaged, so special care should be taken to protect them during storage and handling. The steel plate can be wrapped with a material such as plastic film or cardboard to prevent scratches on the surface.

3.6 Moving PPGI Steel

Careful handling of PPGI steel coils  is required during storage to avoid dropping them on rough ground and to prevent them from breaking.

3.7 First in First out Principle

First-in, first-out principle for steel

Implement the “first-in, first-out” system to ensure that the earliest PPGI  steel coils  are used first.

These are the knowledge about how to store PPGI steel coil  explained to you by Jianhui PPGI steel coil factory. More importantly, these are some common suggestion for storing PPGI coil, and the specific operations need to be adjusted according to the actual situation. During storage metal, always remember to keep the steelwarehouse dry and avoid contact with harmful substances to ensure that its quality and performance are not compromised.
