5.Advantages of Sandwich Panels
1) Heat and sound insulation: The outer steel sheets can maintain the lastingness of the color of the building, and reduce the solar radiation and keep the appropriate indoor temperature. The high quality heat insulation materials are made with the adoption of polyurethane PU and (PIR) polyisocyanurate resin acid hydrogen containing no Chloro-fluoro-carbons (CFC).
2) A degree inflaming retarding: This system can effectively prevent the fire and prevent the fire from spreading during the cross construction and during the use of the boards
3) Environment protection: By learning after the successful experience in environment protection constructions from companies home and abroad and through our scientific analysis, we objectively bear the idea of “low carbon designing, environmental building materials and energy-saving technology” in mind.
4) Super-low heat conductivity: The lowest heat conducting coefficient of the heat insulation boards ensures that, under the condition that the thinnest heat insulation materials are used; the system can meet the energy-saving requirement and offer the strongest basic guarantee to meet the requirement of high standard heat insulation
5) Easily and quick installation

- Q: How do steel sheets compare to galvanized sheets?
- Both steel sheets and galvanized sheets find extensive use across various industries and applications, but they possess distinguishing characteristics that render them appropriate for different purposes. Constructed from robust and enduring low carbon steel, steel sheets exhibit remarkable strength, making them suitable for a wide array of applications, including construction, automotive manufacturing, and fabrication. With varying grades and thicknesses available, steel sheets offer versatility in their usage. When adequately maintained, they provide exceptional strength and resistance against corrosion. Contrarily, galvanized sheets are essentially steel sheets coated with a zinc layer via galvanization. This coating forms a protective barrier against corrosion, thus extending the sheet's lifespan. Galvanized sheets are commonly employed in outdoor applications, where exposure to moisture and harsh weather conditions poses a concern, such as roofing, fencing, and outdoor signage. In comparison to steel sheets, galvanized sheets possess heightened corrosion resistance and tend to endure longer in outdoor environments. However, they may not exhibit the same level of strength as steel sheets and can be more costly due to the galvanization process. Moreover, the zinc coating imparts a distinctive lustrous appearance to galvanized sheets, resulting in a more visually pleasing finish. To summarize, steel sheets exemplify strength, versatility, and suitability for diverse applications, whereas galvanized sheets offer superior corrosion resistance and prove ideal for outdoor usage. The ultimate selection between the two hinges on project-specific requirements, considering factors such as strength, durability, corrosion resistance, and budget.
- Q: How do you prevent rusting on steel sheets?
- There are several effective measures you can take to prevent rusting on steel sheets. 1. Protective Coatings: Applying a protective coating such as paint, enamel, or powder coating creates a barrier between the steel surface and the surrounding environment. These coatings act as a shield against moisture and oxygen, preventing rust formation. 2. Galvanization: Galvanizing steel sheets involves coating them with a layer of zinc. Zinc is highly resistant to corrosion and acts as a sacrificial anode, protecting the steel underneath. This process is commonly used for outdoor applications where steel is exposed to moisture and harsh weather conditions. 3. Proper Storage: Storing steel sheets in a dry and well-ventilated area is crucial to prevent rust formation. Moisture and humidity are major contributors to rust, so it is important to keep the steel sheets away from damp or wet environments. Additionally, storing the sheets off the ground on pallets or racks can help prevent contact with moisture. 4. Regular Cleaning and Maintenance: Regularly cleaning the steel sheets with mild detergent and water can help remove any dirt, debris, or corrosive substances that may lead to rusting. It is important to dry the sheets thoroughly after cleaning to prevent moisture accumulation. 5. VCI (Volatile Corrosion Inhibitor) Packaging: Using VCI packaging materials such as VCI paper or film can be effective in preventing rust on steel sheets during storage or transportation. VCI emits corrosion-inhibiting molecules that form a protective layer on the steel surface, preventing rust formation. 6. Avoiding Contact with Water: Avoid exposing steel sheets to water or other corrosive liquids for extended periods. If the sheets come into contact with water, it is essential to dry them thoroughly as soon as possible to prevent rusting. By following these preventive measures, you can significantly reduce the risk of rust formation on steel sheets and ensure their long-term durability and performance.
- Q: What is the maximum width of steel sheets?
- The maximum width of steel sheets can vary depending on the specific type and grade of steel, but it typically ranges from 72 inches to 96 inches.
- Q: What are the different finishes available for steel sheets?
- There are several different finishes available for steel sheets, including hot rolled, cold rolled, galvanized, and stainless steel finishes.
- Q: Can steel sheets be used for solar panel manufacturing?
- Yes, steel sheets can be used for solar panel manufacturing.
- Q: Are steel sheets resistant to radiation?
- Yes, steel sheets are generally resistant to radiation. Steel has high density and atomic number, which enables it to absorb and scatter radiation effectively. This property makes steel sheets commonly used in industries where radiation shielding is required, such as nuclear power plants and medical facilities.
- Q: What's the corrosion resistance of hot-dip galvanized steel sheet?
- The surface coating of hot-dip galvanized steel can be anticorrosive
- Q: Can the steel sheets be easily cleaned?
- Yes, steel sheets can be easily cleaned.
- Q: What are the common thicknesses for roofing steel sheets?
- Roofing steel sheets come in a variety of thicknesses, typically ranging from 0.4mm to 0.8mm. Nevertheless, the actual thickness required will be influenced by factors like the roofing system type, regional climate, and desired durability level. In regions prone to harsh weather, thicker steel sheets, like those around 0.8mm, are commonly employed, whereas thinner sheets may suffice for less challenging environments. Consulting with a roofing expert or manufacturer is crucial to ascertain the ideal thickness for a particular roofing undertaking.
- Q: What is the impact resistance of steel sheets?
- The impact resistance of steel sheets is generally high due to the material's toughness and ability to absorb and distribute energy upon impact.
