Round and square steel which is strong
From the round and square steel specifications and appearance quality of the steel, 1. force large contact surface and relatively small pressure, 2. and three provide support force and the force behind. The force contact surface of round steel is very strong.
Of course, the round steel is stronger. There was not because round steel is not convenient, a bar where rolling will affect the construction safety and progress. Log and wood with the same size and length to try to lift the increasing weight of the timber is certainly the first break. The cylinder is the strongest and most durable.
The steel production and processing type of hot-rolled and cold drawn two. Hot rolled steel length of 5 ~ 250mm, 3 ~ 100mm length of cold drawn steel.According to the carbon content and the corresponding use, import and export of round steel can be divided into two categories: low carbon round bar and medium carbon. Low carbon raw materials mainly used for wire drawing, forging rivets, bolts and nuts and other metal products. Carbon steel and round steel commonly used to make mechanical parts.
