In order to facilitate the construction and fixation of metal plates in various walls, whether it is used for indoor and outdoor wall aluminum veneers, ceiling aluminum veneers, door shop signs and other decorative aluminum panels, manufacturers will install various corner codes at the edge of the board surface, including flat corner codes, high angle codes, Z-shaped and 7-shaped ones, and special connection corner codes customized according to node requirements, and the most commonly used one is L-shaped countersunk corner The countersunk corner code is used for seamless close splicing aluminum veneer installation. The flat head corner code is more and more rare because there is a certain gap. It is generally used for outdoor curtain wall installation.

What is countersunk corner codes

The so-called countersunk head means that the rivets and screw heads on the corner bar are flush with the board surface after installation. For details, please refer to the following legend;

L type corner code specification:

The size is 20 * 40 * 3mm. The width of both sides is 20mm, the length is 40mm, and the thickness is 2-3mm. Because the corner bar is the stress connection point of the whole board surface, it has higher requirements on hardness and anti-oxidation performance, so the corner code material requirements are made of 3003 series manganese aluminum strip by die stamping.

In the previous article, we have a general understanding of the differences and functions of various corner codes, and the specific selection depends on the engineering design requirements, plate joint requirements, etc. If there are no clear requirements, it is recommended to use the joint installation, which has several advantages; it can prevent the wall settlement from extruding the deformation of the plate surface to achieve a certain role of anti-seismic joint, and the requirement of skeleton accuracy can also be reduced, and the construction of plate arrangement is more flexible.

Using countersunk angle code technology, there is no screw or rivet to produce plate seam, the plate edge can be perfectly close together. It's called close spelling.
