The concept of many people customizing aluminum alloy doors and windows is that the more solid the material, the better. They believe that with more materials, the corresponding price will be higher, and the quality will naturally be better. Is the thicker the wall thickness of aluminum alloy door and window profiles, the better?

Below, the editor of Jianjing Doors and Windows will provide a detailed introduction to the factors that should be considered when choosing aluminum alloy doors and windows.

1. Consider the rationality of aluminum profile design

The thickness of aluminum alloy door and window products is not selected based on the minimum wall thickness specified in the specifications, but rather based on the size of the door and window openings, wind pressure values, and the requirements for air and water tightness in the design of the doors and windows. Under the requirements of ensuring product safety, performance, and environmental protection, the thicker the wall thickness of door and window profiles, the better the product quality.

Due to the excessive thickness of the profile wall, the airtightness and water tightness of the product cannot be improved, resulting in high product quality. On the contrary, it will lead to excessive waste of resources. Moreover, products with excessive thickness require more consumables than those that meet national standards, which will inevitably lead to high product prices and unnecessary economic burdens for consumers.

2. Consider whether the water tightness and air tightness meet the standards

If a door or window has an unreasonable profile design and fails to meet water and air tightness standards, even if its wall thickness exceeds N times the national standard, it is not a good product.

3. Consider whether other configurations are qualified

Hardware accessories are the heart of doors and windows, not supporting role! If the hardware accessories selected for a window are not good, then this door and window are also not durable. So the selection of door and window hardware is also very important.

Characteristics of high-quality aluminum profiles

1. Raw Material - Aluminum: The aluminum used for good aluminum alloy doors and windows has a smooth and shiny surface, without aluminum chips, burrs, etc., and the wall thickness of aluminum alloy door and window profiles has national standards: the wall thickness of window profiles is 1.8mm, and the wall thickness of door profiles is 2.0mm. The wall thickness of aluminum alloy profiles is only one of the measures of the performance of aluminum alloy doors and windows.

2. Raw materials - Hardware accessories: The quality of hardware accessories such as hinges, door handles, locks, pulleys, etc. is the key to the service life of aluminum alloy doors. The use of branded hardware can effectively improve the overall effectiveness and lifespan of windows.

3. Auxiliary accessories: The sealing strip is an important accessory for aluminum alloy doors, especially for hollow doors. The sealing strip must have sufficient tensile strength, good elasticity, good temperature resistance and aging resistance, and the structural dimension of the section should match the aluminum door profile.

Of course, the specific situation still needs to be considered. A thickness of 1.4mm is basically sufficient for a swing door, and the square number is not large. A thickness of 1.4-1.6mm is commonly used for sliding doors. Broken bridge windows should have a thickness of 1.8mm according to the national standard. If the sliding door area of the window is relatively large, a thickness of 2.0mm can be chosen.
