What is the opening part of the aluminum profile and the closed part?

The opening and closing parts of the aluminum profile refer to the two ends of the aluminum profile, which are open and closed respectively. Generally speaking, the opening part is used to connect or secure other items, while the closed part is used to prevent the entry of the object and protect the internal structure. Starting from the actual use requirements, the opening and closing parts of the aluminum profile are very important design elements.

From the point of view of connection, the opening part of the aluminum profile is usually used to install various accessories and accessories, which is convenient for connection with other items. For example, bolts, screws and other fixing tools can be used to tightly attach other items to the aluminum profile. The corresponding part is the closed part, which can not only avoid the entry of dust and debris, but also make the aluminum profile more durable and durable, and enhance its service life.

From the perspective of protection, the closed part of the aluminum profile can effectively protect the internal structure from external factors. For example, it prevents water, gas, dust, etc. from entering the inside, and prevents metal from being oxidized and corroded. When it is necessary to attach or disassemble the workpiece, it is necessary to operate through an open opening.

In addition to the above two aspects, the opening and closing parts of aluminum profiles also have other different characteristics in practical application. For example, in some situations where rolling wheels or guide rails need to be assembled, the opening is particularly important. When circuit wiring is required, the opening of the aluminum profile is also needed to facilitate the cable crossing.

The opening and closing parts of the aluminum profile are very important design elements, which improve the practicality and safety of the aluminum profile from multiple perspectives such as connection and protection. When using aluminum profiles, we should fully consider these two aspects, and choose the corresponding open and closed structures according to actual needs.

"Open part" and "closed part" are derived from "open profile" and "closed profile". Closed, refers to the outer contour of the profile to form a closed box-shaped body; Open, for which the outer contour is not closed or not completely closed. However, many practical profiles are more complex in shape, and are composed of a closed part and an open part, which naturally produces the "opening part" and "closed part".

The minimum value of the thickness of the main stressed part of the column section is mainly based on the provisions of the national standard "Aluminum Alloy Building Profiles" GB T5237 on the minimum thickness of curtain wall profiles.

Love to ask the answer to the winding path.

It needs to be clear.

Aluminum has an outer contour opening, an outer contour is closed, and a plane is used to cut the opening, and the plane is intercepted.

Aluminum: Aluminum: Products made from aluminium and other alloying elements. It is usually processed into castings, forgings, foils, plates, belts, tubes, rods, profiles, etc., and then made by cold bending, sawing, drilling, assembling, coloring and other processes.

The main metal element is aluminum, and some alloying elements are added to improve the performance of aluminum. Classification of aluminum products: rolled products, cast materials, non-heat treated alloys, pure aluminum alloys (1 series), aluminum-copper alloys (2 series), aluminum-manganese alloys (3 series), aluminum-silicon alloys (4 series), aluminum-magnesium alloys (5 series), aluminum-magnesium-silicon alloys (6 series), aluminum-zinc-magnesium alloys (7 series), aluminum and other element alloys (8 series).
