Brand and manufacturer reputation: First of all, it is key to choose well-known brands and manufacturers with good reputation. Well-known brands and high-quality manufacturers usually have advanced production processes and strict quality control systems to ensure the stability and durability of the products.
Appearance and color: Observe the appearance and color of the profile. High-quality UPVC profiles should have a smooth surface, uniform color, and no obvious color difference. High-grade UPVC profiles are usually white with a bluish color, which has better anti-aging properties. Avoid choosing profiles with yellowing colors or obvious color differences, which may mean poor quality.
Wall thickness and structure: The wall thickness and structure of the profile are also important factors in judging quality. The thicker the wall of the UPVC profile, the better its strength and durability. In addition, the multi-cavity design can provide better thermal and sound insulation. Therefore, when purchasing, you should pay attention to these key parameters.
Physical properties: Understand the physical properties of the profile, such as compressive strength, impact resistance, weather resistance, etc. These properties directly affect the use effect and life of the profile. You can learn this information by checking the product’s quality inspection report or consulting the salesperson. Price and value: Although price is not the only criterion for measuring quality, too low a price often means a compromise in product quality. Therefore, when purchasing, do not just pursue low prices, but consider the cost performance of the product comprehensively. At the same time, avoid buying cheap products of unknown origin to avoid quality assurance. Service and support: Understand the manufacturer’s after-sales service policy and technical support. High-quality manufacturers usually provide comprehensive after-sales service and technical support to ensure that problems encountered during use can be solved in a timely manner.
