Summary: Who are the suppliers of paint coatings for Baosteel's color coated steel sheets?

Why is Baosteel's color steel sheet more expensive than others?
The design lifespan of general industrial buildings is typically 15-20 years. Baosteel colored steel panels do not require replacement within this lifespan. Generally, colored steel panels have a lifespan of 7-8 years, or even shorter, necessitating at least one replacement during the design period. While Baosteel colored steel panels are indeed more expensive than standard colored steel panels, priced hundreds to thousands of dollars higher, the cost of using Baosteel colored steel panels, when factoring in replacements over the design lifespan, is only about 60% of the cost of standard colored steel panels.
Color-steel plates, as a building material, their quality cannot be reflected in the short term. Many users in the market still determine the selection of color-steel plates primarily by price, which is actually unscientific. Although the initial investment is saved, the lifespan is shortened, and the cost of later maintenance is very high. This includes factors such as high labor costs, impact on corporate image, and disruptions to production during replacement and maintenance.
How can I purchase authentic Baosteel color steel sheets?
With the rise 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 what they want? Below, we introduce several methods.
How to identify Baosteel colored steel plates:
1. Regarding pricing. Baosteel's color steel sheets, known for their high quality domestically, typically range from 6,000 to 10,000 yuan (in Shanghai). If you're getting them for around 3,000 to 5,000 yuan, that's a red flag. The era of excessive profits in the steel trade industry is over. With a shift towards service-first and increasingly fierce competition, the prices of Baosteel's color steel sheets in the market are also very transparent. The price differences between companies' shipment prices usually fluctuate around 30 to 50 yuan.
2. Pickup Location. Baosteel's color coated steel sheet production bases are located in Baoshan, Shanghai, and Huangshi, Hubei. Therefore, it is generally at Baoshan, Shanghai for delivery of Baosteel color coated steel sheets. Baosteel Huangshi color coated steel sheets are available in stock both in Shanghai and Huangshi, Hubei. It is recommended to pick up at the production site. Authentic Baosteel products are stored in warehouses, and there are corresponding inventory records upon shipment. Wu Wenyong from Shanghai Chuanli Metal Materials Co., Ltd. This ensures 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 Baosteel Color Coated Steel sheets feature electronic spray codes, with markings such as TDC51D+Z or AZ, furnace number, color code (e.g., Sea Blue 404), and production date, which can be matched with the information on the outer label of the coil and the warranty certificate. Additionally, since May 2016, Baosteel has started to use full-line QR code spray code anti-counterfeiting labels on all color coated steel coils, with QR codes spray-coded every 3-5 meters. Users can scan the QR code on the back of the coil with WeChat, which will display the exact date and time of production, the number of times the spray code has been scanned, and the regions where it has been scanned, among other details. Baosteel's implementation of this new QR code spray code anti-counterfeiting measure is truly a blessing for all Baosteel Color Coated Steel users, further ensuring that customers can purchase genuine color coated steel coils from the Shanghai Baosteel headquarters. Shanghai Chuanli Metal (in case the spray coder is broken, manual coding is used at the head and tail of the coil. Of course, this is not the standard for identifying whether the color coated steel is from Baosteel or not).
Customers who purchase simultaneously can request a quality certificate for Baosteel's color steel plates. The steel coil number, furnace number, net weight, zinc coating content in the warranty certificate are all correspondingly matched with the color steel plate label and the QR code scan results.
The quality guarantee certificate can be verified for authenticity on Baosteel's online platform, you can also scan the QR code on the quality guarantee certificate, or directly call Baosteel's after-sales hotline 400-820-8590 for verification.

Baosteel Color Coated Sheet Roof and Wall Panels Fasteners
One, Fasteners for Baosteel Color Coated Sheets: Since roof and wall panels made of Baosteel color coated sheets have a long lifespan, the lifespan of the fasteners should be consistent with the color coated sheets and accessories. Compared to the fasteners, which represent a smaller proportion of the construction investment, choosing poor-quality fasteners does not provide benefits. Therefore, the selection of fasteners should primarily consider the long-term performance and aesthetics of the building. Baosteel color coated sheet fasteners come in a wide range, including self-tapping and self-drilling types made of various metal materials, as well as fasteners made from non-carbon polymer washer materials to meet the requirements for sheet metal fastening. Fastener materials include carbon steel, 300 series and 400 series stainless steel, and aluminum. Carbon steel fasteners for nuts include cast zinc aluminum alloy, nylon, and 300 series stainless steel. Fastener manufacturers can also paint fasteners according to the color of the roof and wall panels (note: There are also carbon steel fasteners that have been electroplated or mechanically galvanized or cadmium plated, but the coating is too thin (≤0.5mil), and it is recommended not to use them on Baosteel color coated sheets). Users should follow the manufacturer's recommendations for the application of fastener products. During installation, fasteners should be tightened moderately, avoiding over-tightening and tilting. Incorrect fastening positions and loose screws can lead to leaks, which in turn make the insulating film moist and cause underfilm corrosion on the steel plate. Over-tightening can cause some surface deformation, leading to water accumulation and accelerating corrosion. Using a fastening tool with depth probe and appropriate RPM speed will help prevent these issues; avoid using impact-type fastening tools.
The sealant for Baosteel's color coated steel sheets: Generally, double or triple-oval sealants are used for bonding the junctions of roof panels and decorative materials. Sealants are also used for sandwich panels and sealing. The sealant should be fully coated within the junction area; the sealant coated on the steel sheet surface will deteriorate due to UV (ultraviolet) radiation. Roof panel manufacturers will provide detailed design specifications for the application of sealant at the steel sheet overlaps, auxiliary materials, and sandwich panels. Butyl synthetic rubber, polyester, acrylic, and silicone can be used as sealants. Neutral silicone resin is recommended. Acidic silicone resin reacts with steel sheets to produce a corrosive byproduct with a vinegar-like odor. Polyurethane rubber (aliphatic urethanes) is recommended. Butyl synthetic rubber is suitable for areas without external exposure, such as within joints. Acrylic sealants with a solid content greater than 80% are recommended. Sealant manufacturers can provide detailed descriptions of different sealant products with varying flexibility, elasticity, UV resistance, and weather resistance.
Three, Cutting Edges of Baosteel Color Coated Sheets: The cut edges expose the sheet, coating, and substrate to the environment, initiating electrochemical reactions and corrosion. The extent of edge corrosion is related to the steel sheet thickness, coating system, environment, and exposure angle, which is either vertical (wall panels) or inclined (roof panels).
Four, the dripping edge of Baosteel's coated steel sheet: The dripping edge is severely corroded due to the influence of rainwater and condensation. The initial sign of edge corrosion is the appearance of microscopic bubbles under the edge, which gradually spread across the entire edge over time. For some metal plated products, the bubbles expand at a fixed rate until the red rust appears near the edge of the sheet surface. The rate of bubble expansion for coated products decreases over time, thus making Baosteel's coated steel sheets more corrosion-resistant than common plated products.
Five, Baosteel Color Coated Sheet Side: It is recommended not to slit or have long cut edges on Baosteel color coated sheets, as the cut edges are fully exposed to the environment. Building panel manufacturers should order custom-sized rolled sheets to avoid exposing the cut edges. The edges of the full-width Baosteel color coated sheets are protected by the aluminum-zinc coated layer and the coating.
Six, Roofing and wall panel edges of Baosteel's color coated steel plates: Due to the absence of rainwater and condensation retention, corrosion in this section is weaker than at the drip edges. It is recommended to use full-length plates as much as possible to minimize exposed end cuts.
Section 7: Baosteel Color Coated Sheet Cutting to Size: Edges also need to be cut at door and window openings. Outdoor cutting requires the use of clean, beveled wall panels around the perimeter of the wall. Decorative panels are used to protect the cut edges, and the edges of the decorative panels are also bent and folded as much as possible to hide the cut edges from view.
Summary: Corrosion and Aging Impact Summary on Baosteel Color Coated Sheets

Color-coated steel sheets are environmentally friendly building materials. How to correctly select and use them to extend their lifespan is a concern for many construction professionals. As a steel mill with full-process production, Baosteel has extensive experience in the production and use of color-coated steel sheets. The "Scientific Material Selection" module provides a brief recommendation and introduction for users on the selection and use of color-coated steel sheets.
When selecting color-coated steel sheets, factors such as the natural environment, usage environment, design life, and structural characteristics of the building should be considered to choose the appropriate steel type, specifications, coating, and finishing. Engineering and processing parties take into account the building's safety performance (impact resistance, seismic resistance, fire resistance, wind pressure resistance, snow resistance), residential performance (water resistance, sound insulation, thermal insulation), durability performance (pollution resistance, durability, appearance retention), and cost-effectiveness (cost efficiency, ease of processing, ease of maintenance, ease of replacement). For color-coated steel sheet suppliers, these properties should be translated into steel mill performance and guaranteed. The main performance requirements for color-coated steel sheets include the material's mechanical properties (tensile strength, yield strength, elongation), coating properties (coating type, coating thickness, and coating adhesion), and coating properties (paint type, color, luster, durability, workability, etc.). Wind resistance, impact resistance, snow resistance, and seismic resistance are all related to the material's mechanical properties, as well as the wave pattern of the color-pressed steel sheet, steel sheet thickness, span, and rafter spacing. Choosing the right color-coated steel sheet in conjunction with appropriate design of the pressed steel sheet can meet the safety factor of the building while also reducing the construction cost. The durability, processing performance, and appearance retention of the material are mainly determined by the durability of the coating and coating.
Color coated coil = cold rolled steel + coating (electro galvanized/ hot dipped galvanized/ aluminum-zinc coated) + paint coating
