How to choose high-quality aluminum alloy doors and windows?

Aluminum alloy doors and windows have become the first choice for modern home decoration due to their advantages such as beauty, durability and good sealing. However, the quality of products on the market is uneven, and how to choose high-quality aluminum alloy doors and windows has become the focus of consumers. This article will provide you with a detailed purchase guide from multiple aspects to help you choose a satisfactory product.

1. Understand the basic types of aluminum alloy doors and windows

Aluminum alloy doors and windows are mainly divided into ordinary aluminum alloy doors and windows and broken bridge aluminum alloy doors and windows.

Ordinary aluminum alloy doors and windows: simple structure, relatively low price, but average heat insulation and sound insulation performance.

Broken bridge aluminum alloy doors and windows: adding insulation strips to aluminum profiles to effectively block heat conduction, improve heat insulation and sound insulation performance, suitable for users with high requirements for living environment.

When purchasing, you should choose the appropriate type of doors and windows according to your own needs and budget.

2. Key factors for purchasing aluminum alloy doors and windows

1. Material quality

Profile wall thickness: According to national standards, the profile wall thickness of the main stress-bearing parts of aluminum alloy windows should not be less than 1.4mm, and the main profile wall thickness of doors should not be less than 2.0mm. Products with insufficient wall thickness have poor strength and stability and short service life.

Surface treatment: The surface of high-quality aluminum profiles should be smooth, scratch-free, bubble-free, and uniform in color. The thickness of the oxide film should reach more than 10 microns to enhance corrosion resistance.

2. Processing technology

Splicing accuracy: For high-quality aluminum alloy doors and windows, the splicing parts should be tight, without obvious gaps, and accurate in angles to ensure the stability of the overall structure.

Welding quality: The welding parts should be flat, crack-free, and without leakage to ensure the overall strength and sealing of doors and windows.

3. Sealing performance

Sealing strips: High-quality sealing strips should be soft, elastic, firmly installed, and can effectively prevent air and moisture penetration, and improve the air tightness and water tightness of doors and windows.

Insulating glass: Doors and windows with insulating glass have better heat insulation and sound insulation. When purchasing, you should check whether the glass has the 3C certification mark to ensure that its quality meets national standards.

4. Hardware accessories

Accessory quality: The hardware accessories of doors and windows, such as hinges, handles, pulleys, etc., directly affect the service life and safety. You should choose accessories with good materials and smooth operation to ensure the normal opening and closing of doors and windows.

Sohu

Firm installation: Hardware accessories should be installed firmly without looseness to avoid malfunctions during use.

5. Manufacturer qualifications

Brand reputation: Choose a brand with good reputation and credibility to ensure product quality.

Product identification: Doors and windows produced by regular manufacturers should be marked with product name, model, production date, factory name or trademark in a conspicuous position, and the packaging box should have "moisture-proof", "handle with care", "upward" and other signs.

3. Purchase suggestions

On-site inspection: It is recommended to visit the physical store or exhibition hall to check the product and personally experience the quality and operating performance of the doors and windows.

Multiple comparisons: Compare products of different brands and models, understand their performance, price, after-sales service and other information, and make a comprehensive evaluation.

Sign a contract: When purchasing, you should sign a formal contract with the merchant to clarify product specifications, prices, delivery time, after-sales service and other terms to protect your own rights and interests.

4. Summary

To purchase high-quality aluminum alloy doors and windows, you need to make comprehensive considerations from multiple aspects such as material quality, processing technology, sealing performance, hardware accessories, and manufacturers. Only by field visits and multiple comparisons, and choosing reputable brands and products, can you ensure the use effect and life of doors and windows. During the purchase process, be sure to pay attention to the terms of the contract to ensure that after-sales service is in place, adding peace of mind and comfort to your home life.
