The Exterior Door, as the entrance of a building, not only affects its appearance, but also directly relates to the safety and service life of the building. Its durability depends on various factors, including material, coating, and installation method. The following is a detailed analysis:

1. The impact of material on the lifespan of the outer door

-Solid wood doors: Hard wood (such as oak and walnut) is usually more durable than soft wood and has good moisture and corrosion resistance. However, wood is susceptible to environmental influences and requires regular maintenance.

-Steel doors: Steel doors are known for their strength and weather resistance, making them suitable for harsh weather conditions. But without proper anti-corrosion treatment, it may rust.

-Fiberglass doors: Fiberglass doors are lightweight, sturdy, resistant to shrinkage and expansion, and have good weather resistance and insulation performance.

-Aluminum alloy door: Aluminum alloy material is hard, durable, and not easily deformed, but its thermal conductivity is poor, which may affect its insulation performance.

2. The impact of coatings on the lifespan of external doors

-Acrylic emulsion paint: Strong weather resistance, suitable for ordinary residential and office buildings, with a lifespan of 8-15 years.

-Silicone acrylic latex paint: with excellent waterproof and breathable properties, suitable for humid or heavily polluted areas, with a lifespan of 10-20 years.

-Fluorocarbon paint: super weather resistance and corrosion resistance, suitable for high-end buildings and industrial facilities, with a lifespan of up to 20-30 years.

-PVD coating: It has excellent wear resistance, corrosion resistance, and fade resistance, suitable for harsh environments, and has a long service life.

3. The impact of installation method on the lifespan of the outer door

-Door frame fixation: The door frame needs to be firmly fixed to ensure a tight fit with the wall and prevent deformation due to wind pressure or temperature changes.

-Gap treatment between door and wall: The gap between the door frame and the wall needs to be filled with waterproof material to ensure sealing and prevent moisture infiltration.

-Hardware accessory installation: High quality hardware accessories (such as hinges and locks) are crucial for the service life of doors. During installation, it is necessary to ensure the stability and durability of the accessories.

4. The role of professional suppliers

Choosing a reliable exterior doors supplier is key to ensuring the durability of the door body. Professional suppliers not only provide high-quality materials and coatings, but also offer professional installation services and after-sales support to ensure the long-term stability and aesthetics of the door body.

The durability of an Exterior Door depends on the combined effects of material, coating, and installation method. By selecting appropriate materials, high-quality coatings, and professional installation services, the service life of the exterior door can be significantly extended, while improving the safety and aesthetics of the building.
