The specifications of engineering-grade special-purpose steel sheets are typically designed based on the application field, load-bearing requirements, and installation conditions. Different types of sheets vary significantly in thickness, dimensions, and performance parameters.
Standard Size Specifications: The length and width of engineering-grade special-purpose steel sheets are generally standardized for production. Common specifications include 1220×2440mm, 1200×2400mm, and 600×1200mm, but custom processing is also available to meet project requirements. For metal sheets and composite sheets, roll or continuous sheet forms are also available to accommodate large-area construction or industrialized production needs.
Thickness Range: Different applications correspond to different thickness ranges. Decorative or lightweight partition sheets are typically 3–12mm thick; structural or load-bearing sheets are generally 12–50mm thick; sandwich panels or high-strength industrial sheets can reach thicknesses of 50mm or more. The choice of thickness directly affects the strength, thermal insulation, and sound insulation performance of the sheet.
Note: The text also mentions "standard sizes" and "continuous sheet sizes," which are not directly related to the specifications and are omitted from the translation.] 3. Customization and Engineering Adaptation Specifications
In practical engineering applications, special-purpose steel sheets often require non-standard customization based on design drawings, including irregular dimensions, hole processing, fire resistance rating adjustments, and surface treatment requirements. Furthermore, different environments have specific requirements for the density, fire resistance limit, thermal conductivity, and other performance indicators of the steel sheets; therefore, customization is essential.
