In industrial and commercial settings, sectional door panels are a key component in building efficient, robust and energy-saving door systems. Widely used in environments such as warehouses, production halls, cold rooms, etc., these panels provide excellent security, sealing and space utilisation. In this article, we will introduce the different types of sectional door panels, their application scenarios, technical specifications and pricing considerations to help you choose the most suitable door system for your needs.
What are Sectional Door Panels?
Sectional door panels 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.
Types of Sectional Door Panels
Insulated Sectional Door Panels
Material: Usually a steel outer layer with polyurethane foam or polystyrene foam in the centre, providing good thermal insulation.
Thickness: usually between 35mm and 60mm, selected according to the different needs of thermal insulation.
Application Scenario: Suitable for cold storage, temperature-controlled warehouses and other environments where temperature needs to be maintained.
Non-Insulated Sectional Door Panels
Material: Made of sturdy steel or aluminium with corrosion-resistant material coated on the outer surface.
Thickness: Generally 0.4mm to 0.6mm.
Application Scenario: Suitable for environments that do not require strict temperature control, such as general warehouses or freight aisles.
Aluminium Sectional Door Panels
Material: Made of aluminium alloy with high corrosion resistance, suitable for wet environments.
Thickness: Approximately 0.8mm to 1.5mm.
Application Scenario: Widely used in places that need to resist corrosion, such as seaside warehouses and garages.
Fire-Rated Sectional Door Panels
Material: Made of special fireproof material, such as mineral-filled steel plate, with high fire resistance.
Thickness: usually between 45mm and 70mm.
Application Scenario: Suitable for places with strict fire protection requirements, such as chemical warehouses and factories.
Technical specifications for Sectional Door Panels
Door Panel Thickness
Uninsulated Door Panels: Typical thicknesses are 0.4mm to 0.6mm.
Insulated Door Panels: Typically 35mm to 60mm thick, the greater the thickness, the greater the insulation.
Material
Steel: the most commonly used material, with high strength and good safety.
Aluminium: lightweight and corrosion resistant, suitable for wet or corrosive environments.
Timber: used in residential environments or where there is a specific aesthetic requirement.
Surface Coatings
Polyester coated steel: corrosion and abrasion resistant, suitable for most environments.
Hot-dip galvanised steel: provides additional protection against rust and corrosion.
Powder coated: available in a wide range of colour options, with a smooth and durable surface.
Insulation materials
Polystyrene : lower cost and suitable for general insulation needs.
Polyurethane : offers higher thermal resistance and is suitable for locations with high insulation requirements.

Application Scenarios for Sectional Door Panels
Warehouse and factory environments
Due to their high strength and safety, sectional door panel are widely used in warehouses and production plants. Especially insulated door panels, they control the internal temperature efficiently and save energy.
Cold storage and freezing facilities
Insulated door panels are ideal for cold stores, freezers and refrigerator warehouses. They maintain a constant low temperature and help reduce energy consumption.
Fire-protected areas
Fire-rated sectional door panels are widely used in areas that require strict fire protection, such as chemical storage areas and industrial facilities.
Retail and commercial spaces
Aluminium door panels are commonly used in shopping malls, supermarkets, catering and retail outlets due to their aesthetics and corrosion resistance.
Private Garages
For residential environments, wood or non-insulated steel door panels are commonly used in private garages to provide security and aesthetics.
Why Choose Sectional Door Panels?
Energy efficiency
Insulated door panels reduce energy consumption by insulating against external heat or cold air flow and reducing temperature fluctuations in the room.
Security and Durability
Steel and aluminium materials provide excellent security and resistance to vandalism, ensuring that the door can withstand high-frequency use for extended periods of time.
Space-saving design
Since sectional doors rise vertically when opened, they make better use of space, especially in limited space environments.
Customised options
Sectional door panels can be customised to meet specific needs, including size, colour and material to meet different customer requirements.
Price Considerations
Sectional door panels vary in price depending on material, thickness, customisation options and features.
Non-Insulated Door Panels: Generally less expensive and suitable for projects with a limited budget, priced between $500 and $1500.
Insulated Door Panels: Provide better insulation and are more expensive, usually ranging from $1,000 to $3,000.
Fire-rated door panels: typically cost between $2,000 and $5,000, depending on the fire rating and specifications.
Price fluctuations are also affected by door size, material and customisation requirements.
Conclusion
Sectional door panels are an integral part of a wide range of industrial, commercial and residential applications. Whether in warehouses, cold rooms, factories, or fire zones, these door panels provide excellent performance and long-term durability. By choosing the right materials, specifications and customisation options, users can achieve a better experience and energy efficiency for their needs.
FAQ
Q1: What are Sectional Door Panel?
