The advantages and disadvantages of various connectors for industrial aluminum profiles are introduced.

Industrial aluminum profile is an alloy material with aluminum as the main component. Aluminum bars can be obtained with different cross-sectional shapes by hot melting and extrusion. However, the mechanical properties and application fields of industrial aluminum profiles are different with different proportions of added alloys.

aluminum profile system

The connection of industrial aluminum profiles is mainly realized by connectors, and the modular installation method is simple and strong. There are many kinds of connectors used in industrial aluminum profiles, including angle pieces, built-in connectors, anchor connecting pins, hexagon socket bolts, connecting plates and so on.

Then do you know the advantages and disadvantages of these connectors?

1. Corner pieces

The advantage is that it is convenient to install, the profile does not need to be punched, and it can be fixed directly on the profile groove with bolts and nuts. Moreover, the types of corner pieces, including right-angle pieces, machined corner brackets, 45-degree corner pieces, 135-degree corner pieces, etc., can realize T-shaped, L-shaped and cross-shaped connection of profiles, and can be used in many frame structures, with high connection strength and long solid use time.

The disadvantage is that it is not beautiful enough and belongs to the external connector, and sometimes the corner piece will occupy the space in the profile groove, which is not convenient for the installation of the plate.

2, built-in connectors

The advantage is that it is beautiful, hidden inside the profile, and can realize cross or right-angle connection of the profile.

The disadvantage is that the connection strength is not so good, so it can be applied to light frame structure, and pay attention to its installation method, because the built-in connector will also occupy the space in the profile groove, so you must pay attention to its installation position when installing the plate.

3, the anchor connection is slightly

The advantages are similar to those of the built-in connector, which also belongs to the internal connector, so the aesthetic degree is better. Moreover, the anchor connecting pin is not divided into national standard or European standard, as long as the corresponding one is selected according to the groove width of the profile.

The disadvantage is that it can only be used on the profile of groove 8 or groove 10, and other groove widths cannot be used.

4. Hexagon socket bolts

The advantages are high connection strength, belonging to the internal connector, beautiful and firm, realizing the right-angle connection of two or three profiles, and not affecting the installation of plates, and the application range is wide. I don't know which connection mode to choose, so it is right to choose the hexagon socket bolt.

The disadvantage is that it needs to be punched in advance and the construction period is longer.

5. Connecting plate

The advantages are similar to those of corner pieces. There is no need to punch holes in the profile, but it can be fixed directly on the profile groove with bolts and nuts.

The disadvantage is that it is not beautiful enough, and the connection strength is not as good as that of corner pieces.

How to maintain aluminum alloy profiles?

Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in industry. Let's take a look at how to maintain aluminum alloy profiles.

aluminium alloy extrusions

1. It is advisable to wipe the surface of aluminum profile with soft cloth and towel. It is forbidden to use sandpaper, wire brush or other friction materials to scrub the surface of aluminum profile. Use warm water containing lubricant or neutral cleaning agent to clean it. Acidic or alkaline cleaning agents shall not be used. If washing powder and strong acid-base cleaning agent cannot be used, the surface of aluminum profile will be easily corroded.

2. When the surface of aluminum profile is corroded and polluted, it should be cleaned in time. The scale can be scrubbed with soft cloth and alcohol first, and then washed with water. After cleaning, the anodized film can be polished with excellent topcoat protective wax, or a layer of acrylate-based varnish can be sprayed evenly.

3. According to the use environment, the aluminum profile should be cleaned regularly to keep the brightness.

4, aluminum profile in the process of transportation and transfer, to be extra careful, must be handled with care, beware of bumping to form a bruised appearance; In the process of transportation, it must be covered with tarpaulin to prevent the invasion of rain; It is forbidden to load aluminum profiles loosely during shipment, so as to avoid the impact on the appearance of the profiles.

5. The storage environment of aluminum profiles should be dry and ventilated. During storage, the bottom of aluminum profiles must be separated from the ground with skids, and the distance between aluminum profiles and the ground should be more than 10 cm. It is forbidden to register with chemical data and moisture data.
