The aluminum profiles we are talking about here generally refers to industrial aluminum profiles, industrial aluminum profiles are divided into national standard and European standard, the biggest difference between the two is the edge of the profile as well as the groove, the edge of the European standard aluminum profiles are curved edges, while the national standard aluminum profiles are close to the right-angle edge of the two profiles with different widths of grooves, so the back can be used for different accessories.
And most people use almost all European standard.
The naming rules of profiles are generally named AABBX, the first four represent the length and width of the profiles cross-section, compatible with each other, the last words of different business will be based on the location of the groove, the profile thickness to be named. For example, 4040B, you can know that its cross-section is 40mm×40mm; 1640B is, 16mm×40mm, 2040C is 20mm×40mm, and so on.
Generally the profiles withe the same first two digits can be used in combination, for example, 2020 and 2040 can be put together in combination, 1640 and 4040 can be used in combination. Different series can be connected by some special accessories, such as 2040 and 4040 connection. So how to choose the right profile for you?
The first step is to consider the load-bearing, this is the core, such as used in the kitchen cabinets, suitable for the column has 2060 (personally feel that the strength of 2040 can not reach the strength of the cabinet needs), 3030, 4040, of course, different series of profiles have different thicknesses, if it is the choice of 4040, 1.8mm wall thickness, then after the installation will be very solid.
For example, with a bookshelf wall, many people worry if the strength isn't enough if they use all 2020 connections. If you only use 2020 to build the frame on the end, it is certainly not enough, but the purpose of adding profiles is to serve as the skeleton of the bookshelf wall, and the outer side of the muscle (solid wood panels) covered, so the overall strength of the late no problem. Another thing to say is that we do not think that the "European standard" is other indicators have reached the standard, in the choice of profiles only look at the thickness is not 1.8mm, there are a lot of unscrupulous business people care more about the measurement of thickness of the position of the wall thickening, and even with recycled aluminum.
In fact, indentifying whether the aluminum you buy is good or not, and wether it's good deal or not, is actually the safetest way to judge it by meter weight.
The second step is to consider what I'm going to use this cabinet for, doors or drawers. Here to consider is the distance between the first hole of the drawer (riding drawer) and the border. For example, if you plan to use Ikea's Massey horseback riding drawer later, the distance between the first hole of Massey and the frame is 20mm, then the 4040 aluminum profile can be adapted.
