Steel sandwich panels are a premier building material, engineered for superior insulation and structural efficiency. This product consists of two outer layers of high-strength steel, typically pre-painted galvanized iron (PPGI), bonded to a rigid insulating core, such as Expanded Polystyrene (EPS). As a leading Steel Sandwich Panel manufacturer, ChinaCNU Steel provides durable, energy-efficient solutions ideal for modern construction. Our panels are designed for quick installation, excellent thermal performance, and long-lasting durability, making them a top choice for industrial and commercial projects worldwide.
Our steel sandwich panels are manufactured to exacting standards, offering a range of specifications to meet diverse project requirements. Below is a detailed overview of our standard product parameters.
| Grade | Thickness (mm) | Width (mm) | Core Material | Steel Coating / Color | Standard |
|---|---|---|---|---|---|
| SGCC, DX51D | 50, 75, 100, 120, 150 | 1150, 1200 (Customizable) | EPS (Expanded Polystyrene) | Zinc Coated (GI) or PPGI (Various Colors) | ASTM, JIS, GB, EN |
| SGCC, DX51D | 40, 60, 80, 100 | 1150, 1200 (Customizable) | Rock Wool, PU (Available) | Zinc Coated (GI) or PPGI (Various Colors) | ASTM, JIS, GB, EN |

Selecting ChinaCNU Steel as your Steel Sandwich Panel supplier guarantees quality, reliability, and expert support. Here are the key reasons to partner with us:
The price for our Steel Sandwich Panel varies based on core material (EPS, rock wool, PU), thickness, steel grade, color coating, and order volume. We offer highly competitive FOB Qingdao pricing, leveraging our direct manufacturing advantage. For the most accurate and up-to-date EPS sandwich panel price or PPGI insulated panel cost, please contact our sales team with your detailed specifications. We provide free, no-obligation quotes within 24 hours.
A properly installed color steel wall panel or roof system from ChinaCNU Steel can have a service life of 20-30 years. The longevity depends on the quality of the PPGI coating, the local environment (e.g., coastal or industrial areas), and regular maintenance. Our panels use high-quality galvanized base steel and durable paint systems for enhanced corrosion resistance.
Yes, customization is a core service. We can tailor the panel width, total thickness, core density, and the color of the PPGI insulated panel to match your architectural plans or brand colors. Please provide your specific requirements during inquiry for a precise quote.
Using an EPS sandwich panel for cold storage offers excellent thermal insulation with a low K-value, effectively maintaining temperature and reducing energy costs. EPS is also moisture-resistant, lightweight for easier installation, and cost-effective compared to some other core materials, making it a popular choice for temperature-controlled environments.
We use robust, weather-proof export packing. Panels are stacked on wooden pallets or in a sturdy steel frame, securely strapped, and wrapped in multiple layers of waterproof plastic film. This method, proven through our exports to over 50 countries, protects the panels and the color steel wall panel surface from moisture, scratches, and transit damage.
