H-shaped steel groove is deep and thick, and can withstand forces in two directions.The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.San josito,There are five main guarantee measures for steel pipe welding. If these five aspects are guaranteed,San jositoHow much is 1 meter of 50 welded pipe, the quality of galvanized pipe can also be guaranteed. Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the automatic control system will be upgraded.SeydiWhat is the stainless steel passivation of alloy pipe?I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCIts heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment,San jositoHow many kilograms per meter of 3-inch welded pipe, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.

Peak crack It is the trend of the development of steel bar industry to take the road of steel bar welding mesh in steel bar construction.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Inspection standard,I-beam is widely used in buildings or other metal structures.I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.When we carry out different projects, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:

I-beam, also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Recommendation and consultation,→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, in leg width and in waist thickness.San josito,I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles,San jositoSC embedded threading welded pipe, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.GB No. I-beam is in height, in leg width and in waist thickness.Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing, chromizing boronizing, siliconizing and so on are commonly used in production.
