1. Excellent Decorative Performance: High-quality exterior wall paint should offer vibrant colors and strong color retention, ensuring long-lasting visual appeal and maintaining its decorative effect over time.

2. Superior Weather Resistance: Since exterior coatings are constantly exposed to the elements, they must withstand wind, sunlight, salt spray, rain, temperature fluctuations, and other environmental stresses. Over time, these conditions can cause cracking, chalking, peeling, or fading, which compromises the coating’s protective and aesthetic functions. Therefore, it's essential that the coating remains intact and functional throughout its expected service life.

3. Strong Stain Resistance: In regions with heavy industrial activity or high pollution levels, atmospheric dust and particulates can easily stain walls, dulling their appearance and reducing their visual impact. To prevent this, exterior coatings should be designed to resist stains and allow for easy cleaning when necessary.

4. Excellent Water Resistance: Exterior finishes are frequently exposed to rain and moisture. A good coating must be water-resistant to prevent damage from water penetration, which can lead to mold growth, discoloration, or structural issues.

5. Effective Mildew Resistance: In humid climates, mildew and algae growth on exterior surfaces is a common problem. The coating should have properties that inhibit mold and algae development, keeping the surface clean and visually appealing.

Additionally, depending on the specific design requirements, exterior wall coatings may need to meet more advanced criteria. For example, in insulation systems, the coating should have elasticity to accommodate minor substrate movements and prevent cracks from forming. For aluminum composite panels, the coating should provide a realistic metallic texture and maintain durability under harsh outdoor conditions. These features ensure both aesthetic value and long-term performance of the building’s exterior.

All aluminum alloy material has strong plasticity and never rusts. Fluorocarbon baking powder is delicate, smooth, and long-lasting without fading. The product is intelligently matched with various smart devices, making it a minimalist, luxurious, and youthful fashion design style.

Advantages of aluminum doors:
Strong and durable: Aluminum alloy has high strength and hardness, can withstand the collision and wear in daily use, and has a long service life.
Corrosion resistance: Aluminum will naturally form an oxide film in the air. This oxide film can effectively prevent aluminum from further oxidation and corrosion, making it stable and not easily damaged in environments such as moisture, acid and alkali.
Good fire resistance: Aluminum alloy has good high temperature resistance, which can play a role in fire prevention to a certain extent and increase the safety of living.
Good sealing: Aluminum doors can be equipped with high-quality sealing strips to effectively improve the sealing performance of the door, and have significant sound insulation, heat insulation, and dustproof effects.
Various styles: Through different surface treatment processes and designs, a variety of colors and styles can be achieved to meet different decoration styles and personal preferences.
Environmental protection: Aluminum is a recyclable material and conforms to the concept of environmental protection.
