GI coil is a steel plate with an organic coating. It has the advantages of good corrosion resistance, beautiful appearance, easy processing and molding, and has the original strength of the steel plate at a lower cost.
It is widely used in construction appliances, transportation and other industries. For the construction industry, it is mainly used for roofs, walls and doors of steel structure factories, airports, warehouses and refrigeration and other industrial and commercial buildings.
1. GI coil substrate thickness
The thinner the color-coated steel coil, the higher the price.
For example, the price of 0.13-0.16mm is relatively high
Price changes for 0.3-0.45mm are smaller
The price of 0.45-0.7 is the same
2. GI Zinc layer thickness
The price depends on the different thicknesses of the zinc layer.
For example, the prices of 20 grams of zinc layer and 50 grams of zinc layer are very different. If the customer has no requirements for the zinc layer, it is recommended to give priority to steel coils with a zinc layer of about 30 grams, which is more cost-effective.
The price of color coating is also affected by the aluminum content: the price of color coating with 25% and 55% aluminum content is quite different. If the customer's environment is average, you can choose color-coated steel coils with an aluminum content of about 25%. If used in humid, outdoor and tropical climates all year round, it is recommended to choose a color coating with a higher aluminum and zinc content.
Impact of special product coating requirements: Some products require coating to prevent scratches or have special functions, which will incur the cost of coating.
GI Coil's packaging includes simple packaging, standard export packaging and special packaging.
Standard export packaging: The outer surface is waterproof kraft paper and galvanized iron packaging. The outside of the steel coil is protected by galvanized iron sheet. It is used for long-distance transportation and containers and is reinforced with steel wire. It can better protect the surface of the color-coated steel coil and has better waterproof effect. This type of packaging is the most widely used.
Special packaging: including vertical packaging or customer-required packaging. This packaging method can calculate the price based on the packaging cost. Vertical packaging is a roll with the core upward and the bottom fixed on a wooden pallet.
This packaging method protects the steel coils from external forces to the greatest extent, but the packaging and labor costs are high.
