Container House Partition Boards

Common types of partition boards used in container houses include color-steel sandwich panels, rock wool sandwich panels, polyurethane sandwich panels, and foam sandwich panels, with their characteristics and applicable scenarios as follows:

Color-Steel Sandwich Panels

Color-steel sandwich panels are composed of two layers of colored coated steel sheets with an intermediate core material, typically polystyrene (EPS) or polyurethane (PU). Their advantages lie in their lightweight, high strength, and easy installation. Additionally, the colored coating on the surface provides corrosion resistance and weather resistance, extending the service life. These panels are widely used in scenarios such as construction site dormitories and temporary offices. For example, the 'Factory Fireproof Ceiling Sandwich Rock Wool Panel 1150 Type Mobile Prefabricated House Partition Wall Enclosure Metal Color-Steel Sandwich Panel' provided by Foshan Hongxinda Metal Technology Co., Ltd. combines fire resistance with structural stability, making it suitable for environments with high safety requirements.

Rock Wool Sandwich Panels

Rock wool sandwich panels are made from natural ores such as basalt, which are melted at high temperatures and formed into fibrous core materials. They feature Class A fire resistance, sound absorption and noise reduction, and excellent thermal insulation. Their high-temperature resistance limit can exceed 1000°C, and they release no toxic gases when burned, complying with fire safety regulations for public buildings. For instance, the 'K-Type Fireproof Color-Steel House' by Guangzhou Jinge Steel Structure Engineering Co., Ltd. uses rock wool sandwich panels and is suitable for partitions in crowded places such as hospitals and schools, effectively reducing fire risks.

Polyurethane Sandwich Panels

Polyurethane sandwich panels use polyurethane foam as the core material, characterized by high closed-cell ratio and low thermal conductivity, offering superior thermal insulation compared to traditional materials. Their smooth surface allows direct use for interior decoration, reducing secondary construction costs. The 'Polyurethane Sandwich Panel Mobile House' provided by Zhangqiu District Dongtian Environmental Protection Equipment Factory is suitable for scenarios with strict temperature control requirements, such as hospitals and schools, reducing air conditioning energy consumption and improving energy efficiency.

Foam Sandwich Panels

Foam sandwich panels use polystyrene (EPS) as the core material, offering low cost and good processing performance. However, their fire rating is Class B2 (flammable), requiring the addition of flame retardants to enhance safety. These panels are mostly used in temporary buildings or scenarios with low fire safety requirements, such as the 'Mobile Prefabricated House Partition Foam Sandwich Panel' by Suzhou Hongxinda Metal Technology Co., Ltd., suitable for construction site warehouses and workshop partitions, enabling quick setup and cost-effectiveness.
