Building Material

With the continuous development of science and technology, new materials are increasingly used in various fields. Aramid fiber and aramid paper, as new high-performance materials, have received widespread attention in recent years. This article will analyze the current status of the aramid fiber and aramid paper industries and discuss future development trends.Current status of aramid fiber industryAramid fiber is a synthetic fiber with high strength, high modulus, high toughness and excellent wear resistance. It is widely used in aerospace, national defense, security protection and other fields. Currently, global aramid fiber production capacity is mainly concentrated in the United States, Europe and China.1. Production capacity distributionThe United States is the leader in the global ar...

Main component part1. Steel columnThe main load-bearing structural components of steel structures, common industrial factory steel columns are mainly processed and manufactured by welded H-shaped steel.2. Steel beamTogether with steel columns, they form a load-bearing system. Roof truss beams are also called steel frame beams. They are generally represented on drawings as GJL and WJL, and are generally made of H-shaped steel.3. Wind-resistant columnA simple personal understanding is to transfer load and connect, usually expressed as KFZ, and generally made of H-shaped steel.4. PurlinsIts function is to transfer the roof load (wall load) to the beams and columns through the purlins, which are generally C-shaped steel and Z-shaped steel.5. Steel plate gutterIts function is drainage. It is ge...
