Steel forest-Construction steel
There are many famous and wonderful buildings in the world that are amazing, including the Eiffel Tower in Paris, France, and the small waist in Guangzhou, China. Nowadays, due to the rapid development of the economy, the steel buildings in many big cities are also being Since then, it has formed a “steel forest”. In some relatively large cities, such a view of the steel forest can often be seen. Working people often need to go in and out of high-rise office buildings. These office buildings and many of our urban buildings are inseparable from construction steel.
Steel for construction can be divided into steel for steel structure and steel for civil engineering. Steel for steel structure is mainly low alloy steel (Q345) and ordinary structural steel (Q235) sheet. DIN EN S235JR Mild Steel is the European standard of alloy structural steel, It is equivalent to the Chinese standard of GB Q235B.
China’s construction steel is mainly composed of carbon structural steel and low-alloy high-strength structural steel. High-quality carbon structural steel is also used in cold-drawn carbon steel wire and connecting fasteners. In addition, thickness direction performance steel sheets, weathering steels for welded structures, cast steel, and the like are also used in some cases. Q235 material is mostly used for the main structure of light steel, Q345 material is used for the main structure of heavy steel, Q235 round steel is used for pre-buried anchor bolts, hot-rolled steel bars are mostly used for hot-rolled steel bars, and small-sized steel, channel steel, and H-shaped steel are also used. The civil construction steel is mainly rebar, round steel, wire, and section steel.
Steel is one of the commonly used building materials in construction engineering. The steel used includes carbon structural steel, low-alloy high-strength structural steel; steel used in construction engineering, its mechanical properties, process properties, chemical composition, etc. must meet the corresponding standards.
In the “steel forest” of life, we enjoy the visual perception and the convenience of use brought by various buildings, and we must also protect these buildings and build our good life together.
