Due to the abundance of counterfeit Baosteel color coated products in the current market, the following are a few tips for distinguishing authenticity, for your reference only:
1. Baosteel's color coated steel coils are supplied in vertical, precision-packed form with wooden frames securing the bottom, while private factories typically offer horizontal packaging.
2. Request the quality certificate for Baosteel's color coated steel products, ensuring that the quality guarantee includes the coil number, furnace number, net weight, and zinc coating content match the labels on the color coated coils. Also, carefully check the clarity of the labels and look for any signs of tampering, including the internal labels within the steel coil.
3 Verify the authenticity of the warranty certificate by logging onto Baosteel Online or directly call the Baosteel after-sales hotline at 4008208590.
4. Is the net weight of the steel coil consistent with the label's net weight?
5. Peel off the decorative coating on Baosteel's painted steel, the primer of Baosteel is typically yellow-green, while the imitation primers from other private factories for decorative coatings are usually white (important).
6. Baosteel's coated steel back paint is typically steel white, cloud white, or yellow green (fluorocarbon), while other coated steel manufacturers usually offer darker colors.
7. Preferably purchase Baosteel's color-coated steel from authorized Baosteel trading companies.
8. Baosteel's special color specification pre-painted steel sheets, with an order lead time typically around 30 days. Orders should be placed before the 20th of each month, with delivery schedules from the 1st to the 30th of the following month. Standard specifications are usually delivered in the early part of the month, while special color specifications are generally delivered in the middle to late part of the month.
9. Since May 2016, Baosteel has begun full-scale production and use of QR code spray marking anti-counterfeiting labels on its color-coated steel coils. These QR codes are spray marked every 3-5 meters. Users can scan the QR code on the back of the steel coil using their smartphone's WeChat app. The scan result will display the exact year, month, day, and time the coil was produced, how many times the spray mark has been scanned, and in which regions it has been scanned, among other detailed information.

Product Introduction
Color Coated Coil Naming Method
TDC51D+AZ or Z:
T -- Color coated code uses the first letter of the pinyin of the Chinese character "涂"
D -- Cold-rolling Steel Plate
C -- Cold rolling conditions
51 -- Two-digit serial number, generally used for structural steel
D -- Hot Dip
AZ -- Hot-Dip Galvanized Aluminum-Zinc Alloy Sheet
Z--Hot-Dip Galvanized Substrate
Common Steel Material Theoretical Weight Simplified Calculation Method
1. Calculation method for the number of feet per ton of color coated steel sheet: 1000 ÷ 7.85 ÷ base sheet thickness ÷ width (1000 ÷ specific gravity)
2. Calculation method for the number of square meters per ton of color coated steel: 1000 ÷ 7.85 ÷ base sheet thickness
3. Color coated sheet density calculation method: 7.85 base sheet thickness (1000 divided by the number of meters per ton)
0.35 x 914C Sea Blue
The rice output per ton = 1000 ÷ 7.85 ÷ 0.35 ÷ 0.914 = 398 meters/ton
Square feet per ton = 1000 ÷ 7.85 ÷ 0.35 = 364 sq ft/ton
Board weight per square meter = 7.85 * 0.35 = 2.75 kg/m²
Note the difference between specific gravity and weight per meter: The weight per meter = 7.85 * 0.35 * 0.914 = 2.51 kg

Impacts across various regions
The selection of color coated steel plates in different regions primarily considers the local wind and snow loads as well as the corrosion environment.
The wind and snow load primarily considers the safety factor of the structure. Although this is related to the mechanical properties of the color-coated steel plate, it is more concerned with the profile, thickness of the corrugated steel plate, and the connection between plates (recommendations for steel plate materials are described in the trend development). Quantitatively describing the corrosion environment of an area is relatively difficult. There are many factors that affect the corrosion of color-coated steel plates. Up
