The aluminium strip of the Backpack is an important part of the carrying system. Although some brands of Backpacks use aluminum tubes or integrally formed back panels, the carrying system of the single and double aluminum strip structures is still the mainstream of large backpacks. In the past two days, the aluminum strips from the several backpacks on the side of the handle have been removed and some differences have been noticed and posted to share with everyone.

Factors affecting the quality of aluminum strips are cross-section structures and materials.
We first analyze the advantages and disadvantages of several aluminum strips that we can often see from the section structure.
W-shaped aluminum strips are lightweight and strong, but are easily damaged when they are bent too much and cannot be repaired, resulting in high manufacturing costs.
Another type of aluminum w-bar, light weight, high strength, can be repaired after bending is too large, the manufacturing cost is high.
E-shaped aluminum strips are lightweight, strong, and can be repaired after the bending angle is too large. The manufacturing cost is high.
Rectangular aluminum bar, heavy weight, low strength, can be repaired after a large bending angle, and the manufacturing cost is low.
Black rectangular aluminum bar, heavy weight, low strength, can be repaired after bending a large angle,
Coloring can increase aesthetics and lower manufacturing costs.
Here we talk about the aluminum alloy grades and the corresponding physical properties, scope of application.
Our outdoor backpack aluminum strips are commonly available in 6061 and 7001,7075 grades (in fact there are a lot of 5 sub-head aluminum alloys used in low-grade backpacks, which can be easily judged by weight, not in the category we explore). The lower the density, the higher the mechanical performance and the higher the cost. Of course, the same brand of aluminum alloys will have different mechanical properties using different treatment processes. Having said so much, everyone may feel too boring. Next time you say something easy, everyone must follow their posts!
