In recent years, China's aluminum profile processing industry has developed rapidly, with industrial aluminum profile production surpassing that of the United States and becoming the world's * * * * * *. The product range is complete, and the quality is steadily improving. The quality level has been among the international advanced ranks. This book mainly uses industrial aluminum profiles and their accessories produced domestically as examples to introduce how to use industrial aluminum profiles and their accessories to build racks.

1. The main types of aluminum profiles produced domestically include 20 series, 30 series, 35 series, 40 series, 50 series, 60 series, 80 series, 90 series, and 100 series. Each series has different models, and the cross-section of aluminum profiles is also different. Below is a detailed introduction of industrial aluminum profiles and their accessories using the 40 series as an example. (1) The format of the 40 series aluminum profile model name is: xx-8-40xx □, and the specific meaning of each part is: xx: usually defined by the manufacturer themselves, which is usually the abbreviation of the manufacturer's name in English letters. 8: The aluminum profile of this model adopts M8 bolts and T-nuts, which are also the slot width code of the aluminum profile. 40: represents that the model is a 40 series aluminum profile, and also represents that the width of the aluminum profile is 40mm. In the arc shaped cross-section aluminum profile, it represents the arc radius. Xx: This is a number representing the height of the aluminum profile. □: This is a capital English letter representing the cross-sectional shape of the aluminum profile. (2) The main models of 40 series aluminum profiles include 8-4040A, 8-4040B, 8-4040C, 8-4040D, 8-4040GE, 8-4040GF, 8-4040GG, 8-4040R, 8-4080, 8-4080G, and 8-4080GA,

2. The main accessories of industrial aluminum profiles are diverse and can basically meet the needs of designers. The main accessories include bolts, nuts, corner pieces, connectors, end face connecting plates, spacing connecting blocks, elastic fasteners, movable hinges, shoe angles, and casters. (1) The bolts mainly include special bolts, special half round head bolts, special round head bolts, flat machine bolts, and T-bolts. The industrial aluminum profile frame generally adopts the internal link mode, and uses special round head bolts or special bolts. Before installation, it is necessary to tap threads and drill process installation holes at the connection of profiles; Special round head bolts are commonly used for high-strength connection of two sections of profiles, and drilling and threading are required at predetermined positions during connection; The combination of flat machine bolts and T-nuts is commonly used for connecting decorative components such as hinges and handles to profiles; T-shaped bolts are directly placed into the profile groove and can be automatically positioned and locked during installation. They are often used in conjunction with flange nuts and are important connectors for installing corner pieces and other profile accessories. T-shaped bolts of different specifications and lengths can be selected according to different profiles, groove widths, and installation requirements. (2) Nuts mainly include flange nuts, square nuts, T-nuts, and elastic nuts. The flange nut is matched with the T-bolt and used when installing corner fittings and other profile accessories; The T-nut can easily and safely fix other connecting parts in the groove of the profile, and it can automatically position and lock during the assembly process; When installing square nuts, they need to be pre inserted into the groove of the profile to connect various accessories on the profile; The elastic nut can be directly inserted into any assembly point in the profile groove, and the spring steel ball on its back can fix its position, making installation very simple and reliable. It is one of the most commonly used accessories in profile connection. (3) Corner pieces are commonly used connectors for aluminum profiles, usually used for vertical or cross connections. There are three main types of corner pieces: commonly used corner pieces, strong corner pieces, and steering corner pieces. Commonly used corner pieces are used to strengthen the support force of the connected profile points, and can also be used as a connection method for profiles that need to be moved; Strong corner pieces are commonly used for supporting and fixing profiles and profile points that are subjected to strong or vibration; Steering angle pieces are used for cross section connections. The connectors mainly include built-in connectors, angle slot connectors, slot bar connectors, triangular connectors, and diagonal connectors. The built-in connectors are mainly used for cross or vertical connection of profiles. During assembly, installation process holes need to be drilled at the specified size positions of the profiles to embed the accessories. At the same time, the elastic nuts are placed in the grooves of another profile, and then the bolts are locked; There are two types of corner groove connectors, E-type and L-type, used for the right angle connection of two profiles. When installing, insert both ends into the groove of the profile separately, and then lock them with set screws. During installation, different corner groove connectors must be selected based on the slot width and connection method of the profile; The slot bar connector is used for extending the connection between two profiles in a straight line. During installation, it is inserted into the groove at the junction of the two profiles and then locked with a set screw; Triangle connection is a specialized connector for semi circular profiles, which can connect two or three profiles together. Combined with the matching cover plate, it is very simple and beautiful; Diagonal connectors are used for two non 90 ° profiles; The diagonal connection is hidden inside the profile during installation. (4) The end face connecting plate and spacing connecting block end face connecting plate are mainly used for connecting rectangular and large-sized hollow square profiles with shoe angles and casters, playing an excessive role. When using the spacing connection block, first insert the tail end of the connection block directly into the groove of the profile, and rotate it 90° After that, it is tightly fixed on the profile, and various panels such as organic glass can be installed on the connection block, and then locked with bolts, making installation and disassembly easy.
