The indoor LED screen structure is much simpler. At present, the Maipu glare indoor LED screen is usually made very thin, which is beautiful and does not take up too much space. Standing on the front of the LED screen can be easily maintained. The required materials are 40×40mm and 40×20mm square pass, 40×40mm square pass is placed on the bottom to play a fixed role, and 40×20mm square pass is placed on top to separate each square according to the width of the LED module. The square wire is locked in a cross shape by a connecting piece, and finally the assembled structure is fixed on the wall.

Bend is bent by a set of bending equipment, divided into cold simmer and hot push two processes. No matter what kind of machinery and piping, most of them use elbow pipes, mainly for oil transportation, gas transportation, transfusion, engineering and bridge construction, etc.
The material of the elbow is cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metal and plastic. It can be divided into pushing, pressing, forging, casting and so on.
Manufacturing standards can be divided into national standard, electric standard, shipping mark, chemical standard, water mark, American Standard, German standard, Japanese standard and Russian standard.
