Why is Baosteel's color coated steel panel much more expensive than others?
The design lifespan for general industrial buildings is typically 15-20 years. Baosteel's colored steel panels do not require replacement within their design lifespan. In contrast, standard colored steel panels usually have a lifespan of 7-8 years, or even less, necessitating at least one replacement during the design period. While Baosteel's colored steel panels are indeed several hundred to a thousand dollars more expensive than standard panels in the market, when calculating the cost over the design lifespan, the cost of using Baosteel's panels is only about 60% of the cost of standard panels.
Corrugated steel panels, as a building material, their quality is not easily reflected in the short term. Many users in the market still primarily base their choice of corrugated steel panels on price, which is actually not very scientific. Although the initial investment is saved, the reduced lifespan and the high cost of later maintenance can be significant. This includes factors like high labor costs, impact on corporate image, and disruptions to production during replacement and maintenance.
How can I purchase genuine Baosteel color steel plates?
With the popularity of the internet, there are more and more ways to access information, making it increasingly convenient. However, it also brings about烦恼, commonly known as "choice paralysis." Faced with so much information, how can one choose the authentic products they desire? Below, we introduce several methods.
Methods to Identify Baosteel Color Steel Sheet:
1. Regarding pricing. Baosteel's color steel sheets, known for their high quality domestically, typically range from 6,000 to 10,000 yuan (for Shanghai Baosteel color steel sheets). If you come across ones priced around 3,000 to 5,000 yuan, they are most likely not authentic. The era of excessive profits in the steel trade industry has passed. With a shift towards service-first and increasingly fierce competition, the prices of Baosteel color steel sheets in the market are also very transparent, with price differences between companies generally fluctuating around 30 to 50 yuan.
2. Pickup Location. Baosteel's color steel sheet production bases are located in Baoshan, Shanghai, and Huangshi, Hubei. Therefore, Baosteel color steel sheets in Shanghai are generally delivered in Baoshan, Shanghai. Baosteel Huangshi color steel sheets are available in both Shanghai and Huangshi, Hubei. It is recommended to pick up at the production site. Because authentic Baosteel products are stored in designated warehouses, with corresponding inventory details upon shipment. Wu Wenyong, Shanghai Chuanli Metal Materials Co., Ltd. — This is the guarantee of quality control from the source.
3. Product itself. Shanghai Baosteel Color Coated Steel is vertically precision-packed with the core facing up. Huangshi Baosteel Color Coated Steel is horizontally precision-packed. Normally, the back of genuine Baosteel Color Coated Steel panels is etched with electronic codes, indicating the brand number such as TDC51D+Z or AZ, batch number, color code (e.g., Sea Blue [404]), and production date. This information should match the labels on the steel coils and the content of the warranty certificate. Additionally, since May 2016, Baosteel Color Coated Steel coils have been produced with full-line QR code etching for anti-counterfeiting, with a QR code etched every 3-5 meters. Users can scan the QR code on the back of the coil with WeChat, which will display the year, month, day, and time of production, how many times the code has been scanned, and where it has been scanned, among other details. Baosteel's implementation of this new QR code etching anti-counterfeiting operation is a great boon to Baosteel Color Coated Steel users, further ensuring they purchase genuine panels from the Shanghai Baosteel headquarters. Shanghai Chuanli Metal (in case the etching machine is broken, manual etching will be used at the head and tail of the coil. Of course, this is not the standard for identifying the authenticity of Baosteel Color Coated Steel).
Customers purchasing simultaneously may request a quality certificate for Baosteel's color coated steel. The quality guarantee certificate includes the coil number, furnace number, net weight, zinc coating content, which all correspond exactly to the label on the color coated steel and the results from scanning the QR code.
The Warranty Certificate can be verified for authenticity on Baosteel's online platform, scanned using the QR code on the certificate, or directly by calling Baosteel's customer service hotline at 400-820 8590.

The color coated steel sheets produced by Baosteel use coatings supplied by internationally renowned paint companies, including Shanghai Zhenhua, BECKER (Becquer), VALSPAR (Valspar), NIPPON (Nippon), and AKZO NOBEL (Akzo Nobel). These five companies are qualified suppliers of Baosteel's color coated steel sheets, having collaborated with Baosteel for many years.
Baosteel's management of suppliers for Baosteel's color coated steel plate coatings primarily includes the following aspects:
The supplier of Baosteel's color coated steel sheet coatings must meet the relevant requirements of Baosteel's procurement supplier qualification system.
2--The paint for Baosteel's color coated steel sheets must comply with Baosteel's direct factory's quality management regulations for color coated steel sheets paint.
3--Baosteel conducts regular second-party audits on suppliers of Baosteel's color coated steel sheet coatings.
4--All Baosteel color coated steel plate coatings must meet the technical requirements of Baosteel's color coated steel plate coatings procurement.
All Baosteel color coated steel sheets must be inspected and accepted before entering the factory.
All the coatings used for Baosteel's color coated steel sheets must comply with the relevant procedures of Baosteel's color coated steel production line.
In micro terms, the coating is a porous structure. Water in the air and corrosive agents (ions, etc.) can penetrate through the vulnerable parts of the coating, leading to underfilm corrosion, which in turn causes the coating to bubble and peel off. Additionally, even with the same coating thickness, the secondary coating is denser than the primary one. According to overseas reports and corrosion test results, a thickness of 20μm or more of the top coating is required to effectively prevent the penetration of corrosive agents. Due to the different corrosion prevention mechanisms of the primer and topcoat, it is not only necessary to specify the total film thickness but also to separately require the thickness of the primer (>5μm) and the topcoat (>15μm). Only in this way can the corrosion resistance of different parts of the colored coated steel plate be ensured.
PVDF products require thicker coatings to ensure longer service life. The requirements for the backside coating vary depending on the application; for sandwich panels, only a single layer of adhesive primer is required. However, for formed steel sheets, due to the indoor corrosive environment, two layers of coating are necessary. The minimum thickness should be over 10μm.

I. The Impact of Light on Baosteel's Color Coated Steel Sheets
Lighting (especially ultraviolet light) is one of the primary causes of coating aging. Baosteel's color-coated steel sheets are typically affected by light during use, thus, light intensity and duration are crucial factors to consider when analyzing environmental corrosiveness.
II. The Influence of Temperature on Baosteel Color Coated Sheets
Long-term exposure to excessively high, low temperatures, or significant temperature fluctuations can accelerate the aging of the coating.
Section 3: Impact of Chemicals on Baosteel's Color Coated Steel Sheets
Avoid direct contact with chemicals such as acids, organic solvents, detergents, and cleaners during the use of Baosteel's coated steel sheets to prevent corrosion of the coating.
Impact of Deposits on Baosteel's Color Coated钢板
Long-term accumulation of industrial dust and suspended particles on the coating surface can easily lead to coating aging.
V. Impact of Microorganisms on Baosteel's Color Coated Steel Sheets
In humid, poorly ventilated environments, the coating surface is prone to mold growth, which reduces the lifespan of Baosteel's color coated steel sheets.
Section 6: The Impact of Mechanical Wear on Baosteel's Color Coated Steel Plates
The surface of Baosteel's color coated steel sheet may experience erosion after being subjected to the effects of wind and sand abrasion, as well as mechanical friction.
Section 7: Impact of Water and Soil Corrosion on Baosteel Color Coated Steel Sheets
Minimize direct contact between Baosteel's color coated steel sheets and water or soil to reduce corrosion caused thereby.
Section 8: Interaction of Baosteel Color Coated Steel Sheet with Other Materials
Baoshan's color coated steel sheets may occasionally come into contact with or be used in conjunction with other materials. Due to the differing material properties, attention should be paid to whether there may be any interaction between the materials.
In practical application environments, various influencing factors coexist and interact with each other. At this point, it is essential to identify the primary influencing factors and, to the extent possible, determine the relationships between these factors, thereby making a comprehensive and accurate assessment of the application environment.
The price of Baosteel's color coated steel can be approximately 66% higher than the usual Baosteel color coated steel price, not considering other impacts such as the effect on corporate image and the impact on production during replacement and maintenance.
I. Impact of Baosteel Color Coated Steel Sheets in Different Regions
The selection of Baosteel's color coated steel in different regions primarily considers local snow and wind loads as well as corrosion environments.
The wind and snow load primarily concerns the safety factor of the building. Although it is related to the mechanical properties of Baosteel's color coated steel plates, it is more related to the profile, thickness of the corrugated steel plates, 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 Baosteel's color coated steel plates.
II. The Impact of Baosteel's Color Coated Steel Sheets on Different Industries
The usage of Baosteel's color coated steel in various industries can be analyzed from two aspects. Firstly, the exterior panels of Baosteel's color coated steel, typically, are selected based on different regions, but the influence of the local environment must also be considered. This includes whether corrosive agents, such as gases emitted from boiler combustion or sulfur dioxide dust, fall onto the factory's protective structures. During design, factors like the height of the chimney and the primary wind direction in the area should be taken into account. Additionally, the sealing integrity of the factory should be assessed, as high humidity and high temperatures inside the factory may release corrosive gases that condense on Baosteel's color coated steel when exposed to cold outdoor air. This phenomenon should be avoided, as it accelerates localized corrosion. The second aspect is to consider the interior panels (double-layered composite steel plates) or the backside paint (single-layer plates) of Baosteel's color coated steel. It should be noted that the interior panels for roofs are more prone to corrosion compared to those for walls. If workers can operate in such an environment, the use of Baosteel's color coated steel is acceptable. However, the quality of the indoor environment or the investment in environmental protection equipment will directly affect the lifespan of Baosteel's color coated steel. A few years ago, Baosteel had two end-users in Guangxi, both producing electrolytic aluminum. However, the lifespan of their Baosteel color coated steel varied significantly—one factory had their panels completely worn through after one year of operation, while the other has been using their panels for over six years.
