There are many aluminium profile manufacturers, the quality gap is large, and the price difference is large. Before the fabricaton of aluminum doors and windows, the purchased aluminium profiles must undergo strict quality inspection and control in the warehouse. Aluminium Profiles can be inspected with the eye and related instruments for quality. Below are the main aspects for quality test.

1. ISO9001-2008
2. GB/T24001-2004/ISO 14001:2004/ GB/T28001-2001

Aluminium profiles for windows represent a harmonious blend of aesthetics, functionality, and sustainability. Their strength, durability, and resistance to corrosion make them an excellent choice for contemporary window designs, while their potential for thermal and sound insulation enhances the living experience. As the demand for energy-efficient and environmentally friendly building materials continues to grow, aluminium profiles stand out as a solution that addresses these needs effectively. Whether for residential homes or commercial buildings, investing in aluminium window profiles not only elevates the architectural appeal but also contributes to long-term energy savings and environmental conservation.

The powder coated surface should be delicate, full, transparent, strong in three-dimensional sense, and can maintain relative luster for a long time. The decorative surface coating is at least 40um. The poor appearance is dim, the stereoscopic effect is poor, and after a period of time, there is light loss, powdering, paint stripping, etc. Slight orange peel on the surface of powder coated profiles is accepted. There are almost no orange peels on high-quality powder coated profiles, but the orange peel on the surface of poor powder coated profiles is obvious and serious. The reason is the use of poor quality powder coatings, or the production process and production management are not strict.

1. Durability and Strength One of the primary advantages of aluminum glazing beads is their inherent strength. Aluminum is a robust material that can withstand significant impacts and stresses. This durability extends the lifespan of window units and reduces the need for frequent repairs or replacements, making aluminum an economical choice in the long run.
