H-shaped steel
H-beam is a kind of economical section profile with optimized section area distribution and reasonable strength weight ratio. Since all parts of the h-shaped steel are arranged at right angles, the h-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used
The section shape is a kind of economic section profile similar to the capital Latin letter h, also called steel beam, wide flange (edge) I-beam or parallel flange I-beam. The cross section of h-shaped steel usually consists of web and flange plate, also called waist and edge

The inner and outer sides of the flange of h-shaped steel are parallel or nearly parallel, and the end of the flange is at a right angle, so it is called parallel flange I-shaped steel. The web thickness of h-shaped steel is smaller than that of ordinary I-shaped steel with the same height of web, and the flange width is larger than that of ordinary I-shaped steel with the same height of web, so it is also called wide flange I-shaped steel. Determined by the shape, the section modulus, inertia moment and corresponding strength of h-beam are obviously better than those of ordinary i-beam with the same single weight. When it is used in metal structures with different requirements, whether it bears bending moment, pressure load or eccentric load, it shows its performance. Compared with ordinary I-beam steel, it can improve the bearing capacity and save 10%~40% of metal. H-shaped steel has wide flange, thin web, multiple specifications and flexible use, which can save 15%~20% of metal when used in various truss structures. Since the inner and outer sides of the flange are parallel and the edge end is at right angles, it is convenient to assemble and combine various components, which can save about 25% of the welding and riveting workload, speed up the construction of the project and shorten the construction period

Application: due to the above advantages, h-shaped steel is widely used, mainly for: various civil and industrial building structures; Various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activity and under high-temperature working conditions; Large bridges with large bearing capacity, good section stability and large span are required; Heavy equipment; expressway; Ship skeleton; Mine support; Foundation treatment and dam works; Various machine components.

Classification: there are many specifications of h-shaped steel products, and the classification methods are as follows. (1) According to the flange width of the product, it can be divided into wide flange, middle flange and narrow flange h-shaped steel. The flange width b of wide flange and middle flange h-shaped steel is greater than or equal to the web height h. The flange width b of narrow flange h-shaped steel is about half of the web height h. (2) It can be divided into h-shaped steel beam, h-shaped steel column, h-shaped steel pile and extremely thick flange h-shaped steel beam according to the product use. Sometimes, parallel leg channel steel and parallel flange T-shaped steel are also included in the scope of h-shaped steel. Generally, narrow flange h-shaped steel is used as beam material, and wide flange h-shaped steel is used as column material. Therefore, it is also called beam h-shaped steel and column h-shaped steel. (3) According to the production mode, it can be divided into welded h-shaped steel and rolled h-shaped steel. (4) It is divided into large, medium and small h-shaped steel according to the size. Generally, the products with web height h of more than 700mm are called large, 300~700mm are called medium, and those with web height h of less than 300mm are called small. By the end of 1990, the height of h-shaped steel web was 1200mm, and the flange width was 530mm

The price of hot roll is mainly stable and strong. In 20 cities, 3 cities increased by 10-20 yuan/ton, and 1 city increased by 40 yuan/ton. For enterprises, this is also a way to compete for enterprise information. In brief, the main components of various stone protective agents can be divided into two parts. One is that π halo clank plays a functional role in stone protective agents, which only accounts for about 5-l5 of the total. Key point 4: dealers and teams. They were also quite helpless in the face of the adverse situation.
