How to identify the wall thickness of damaged aluminum doors and windows from the surface?
To identify the wall thickness of damaged aluminum doors and windows, it is necessary to find an experienced master to judge by tapping. It is also suggested to measure with a millimeter ruler or vernier caliper. If you need to buy broken aluminum doors and windows, it is recommended to choose gold doors and windows.

Broken bridge thermal insulation profile is a new generation of energy-saving aluminum alloy, which adds a nonmetallic insulator with low thermal conductivity-thermal insulation strip between two groups of aluminum alloys, thus playing a good role in heat insulation, cold preservation and sound insulation. There are two kinds of "broken bridge insulation" strips: puncture type and glue injection type. Through-the-heart thermal insulation profiles are made by inserting thermal insulation strips into two groups of aluminum profiles and rolling them into "broken bridge thermal insulation" aluminum profiles. Glue injection and heat insulation aluminum profile is to inject low thermal conductivity and heat insulation materials into the reserved cavity of the profile, and then cut off the aluminum on both sides of the reserved cavity to form a "broken bridge and heat insulation" profile.

1. From the aspect of profile quality, first of all, what kind of treatment method is used for its surface treatment. If the surface is a common oxide profile, first check whether the thickness of the oxide film meets the standard. The oxide film thickness standard stipulated by the state is generally above 10μm for doors and windows, and above 10μm for curtain walls. The oxide film has strong wear resistance, weather resistance and corrosion resistance, can form various colors on the surface of the substrate, and has strong hardness and impact resistance.

2. See if the geometric angle of the outline is accurate. The profile should not be bent and twisted, and the angle should be correct.

3. See whether the thickness, purity, hardness, toughness and compressive strength of the profile meet the requirements, and whether there are extrusion lines on the surface of the profile, and then measure the thickness of the profile with calipers.

If you want to know more about broken aluminum doors and windows, I suggest you consult Zheng Jin doors and windows that have been certified as green building materials in China. The rapid development of doors and windows in Zheng Jin over the years can not be separated from stable quality suppliers, material suppliers and hardware accessories supply chain. After years of running-in and common struggle, the company has eight production auxiliary bases and supply chains at home and abroad, which can make customers feel at ease, improve the service life of products and make customers feel more at ease about quality.
