Steel PU Sandwich Panels
Steel-clad polyurethane sandwich panels are high-performance insulation materials featuring high-strength outer layers and excellent thermal insulation properties. They consist of two layers of high-strength steel plates and a polyurethane foam core, bonded together using vacuum-assisted high-pressure lamination. These panels are commonly used in refrigeration applications, construction, and industrial settings. We are a professional manufacturer of steel-clad PU sandwich insulation panels.
Features
Steel-clad polyurethane sandwich panels are ideal for applications requiring high-strength thermal insulation, commonly used in wall insulation and building structures. Their thermal insulation properties help reduce building energy consumption and enhance living comfort. Polyurethane provides lightweight structural support, while the steel surfaces are treated with a special corrosion-resistant coating, enabling them to withstand harsh environmental conditions.
They are also a recyclable material, minimizing environmental impact and offering a long service life.
