<\/span><\/h2>\n\n\n\nSectional door panels<\/strong> are the individual components that make up the body of a sectional door. They are usually connected by multiple hinges and can be opened vertically and rolled into the top track. Depending on the requirements, these door panels can be made of different materials (e.g. steel, aluminium, wood) and in different thicknesses to meet the requirements of various industrial and commercial applications.<\/p>\n\n\n\n<\/span>Types of Sectional Door Panels<\/strong><\/strong><\/span><\/h2>\n\n\n\n<\/span>Insulated Sectional Door Panels<\/strong><\/strong><\/span><\/h3>\n\n\n\nMaterial:<\/strong> Usually a steel outer layer with polyurethane foam or polystyrene foam in the centre, providing good thermal insulation.<\/p>\n\n\n\nThickness:<\/strong> usually between 35mm and 60mm, selected according to the different needs of thermal insulation.<\/p>\n\n\n\nApplication Scenario: <\/strong>Suitable for cold storage, temperature-controlled warehouses and other environments where temperature needs to be maintained.<\/p>\n\n\n\n<\/span>Non-Insulated Sectional Door Panels <\/strong><\/strong><\/span><\/h3>\n\n\n\nMaterial: <\/strong>Made of sturdy steel or aluminium with corrosion-resistant material coated on the outer surface.<\/p>\n\n\n\nThickness:<\/strong> Generally 0.4mm to 0.6mm.<\/p>\n\n\n\nApplication Scenario:<\/strong> Suitable for environments that do not require strict temperature control, such as general warehouses or freight aisles.<\/p>\n\n\n\n<\/span>Aluminium Sectional Door Panels<\/strong><\/strong><\/span><\/h3>\n\n\n\nMaterial:<\/strong> Made of aluminium alloy with high corrosion resistance, suitable for wet environments.<\/p>\n\n\n\nThickness:<\/strong> Approximately 0.8mm to 1.5mm.<\/p>\n\n\n\nApplication Scenario: <\/strong>Widely used in places that need to resist corrosion, such as seaside warehouses and garages.<\/p>\n\n\n\n<\/span>Fire-Rated Sectional Door Panels<\/strong><\/strong><\/span><\/h3>\n\n\n\nMaterial:<\/strong> Made of special fireproof material, such as mineral-filled steel plate, with high fire resistance.<\/p>\n\n\n\nThickness: <\/strong>usually between 45mm and 70mm.<\/p>\n\n\n\nApplication Scenario: <\/strong>Suitable for places with strict fire protection requirements, such as chemical warehouses and factories.<\/p>\n\n\n\n<\/span>Technical specifications for Sectional Door Panels<\/strong><\/strong><\/span><\/h2>\n\n\n\n<\/span>Door Panel
