Since H beams and joists are two important parts of a building, some people confuse the two. They have different prices as well per kg or per length. Differences in material and use of joists and beams should also be taken into account. Beams have a number of uses. One of the well-known uses of rebar is column bases. Certain types of wide putty have a nearly square cross-section, are used for posts, and are used vertically. Another most important use of iron beams is as a main beam or girders. The connection between the main beam and the column is made by cutting or simply. 
The primary beam, as one of the horizontal parts of the structure, undertakes the task of transferring the primary load from the secondary beam to the columns. Columns are important members of the structure and are used in 3 forms: side, corner and center. These structural elements are responsible for transferring vertical and horizontal wind forces to the foundation. Cross beams are also used for center beams or side beams. The beams used in the center piles are connected horizontally with the main beams. Coil beams, narrow chrome iron beams and rafters are also made from iron beams. Joists are one of the structural elements that help beams perform similar tasks. Both these members are very important in building construction and cannot be compared in terms of importance of use. In fact, the use of joists next to beams helps to increase the strength of the building. Beams are one of the most used steel sections in construction. The use of large amounts of steel results in construction costs that largely depend on the price of the sections used, including the price of the beams. This steel profile is one of the best profiles for metal framing due to its high strength against shear forces and bending moments. Here are some reasons to use steel beams in construction:
- Increases structural strength and resistance to bending and shear loads
- Reduce the amount of steel required for construction
- Speed and ease of implementation and use
- Possibility of easy execution at great heights
H beam and joist per kg
H beam and joist are two products used in the construction industry and bought per kg or ton. In general, beams are long sections consisting of a web and two wings and are often used to make roofs and columns for building skeletons. The main materials for the manufacture of this product are rectangular billets and plates, which are heated at high temperatures of 1100 degrees Celsius and converted into iron bars through several rolling stages. You can see the production process of iron beams from this link. In the industry, logs fall into two broad categories, regular and hashed. Regular beams are I-shaped and Hash beams are H-shaped and belong to the wide wing section. The rolling of the wide spar and common spar is basically divided into two general methods. This division is generally divided according to the shape type of the raw material, which is a rectangular plate or an H-type. Based on this, the shaping in the production of beams made using the H shape can be carried out uniformly due to the high similarity of the final product to the raw material. Despite the fact that they use rectangular plates to make heavy products of various sizes. The rolling of the beam occurs in such a way that the width of the plate increases, which is important to achieve a certain width. For this reason, sheet preparation methods are required to produce products of different sizes and requirements. 
A very important point in using this method is the precise guidance of the plate during the rolling process, as the final product may become unbalanced and its thickness and dimensions may not be uniform. In the final stage, the product is cut to standard lengths, usually equal to 12 meters. Its beams are made by hot rolling like ordinary beams. The rolling of his Beam is divided into four steps and in the above order. The first is rerolling, where the sheet will increase in width and decrease in thickness by placing it between two handles and applying pressure. Then the plates are placed in two intermediate rolling stages where the plates have basic dimensions of width and height, in the last rolling stage the dimensions are fully determined and the curve of the product is obtained and in a certain length should be cut. There is another method for the production of wide putty: after the bar is placed on the rollers in the hot rolling mill, it is pressed by two pressure bars, and then the edge of the beam is shaped with special rollers. The next step sends the thickness of the beam, and in the last step, the height of the beam is determined by the pressure roller handle. During the process stage of adjusting the desired dimensions of the beam, the cooling stage of the product is simultaneously carried out using water the product. 
H beam price per kg
The main difference between H beam and I beam per kg and the price is as followed. Types of H-beam and I-beam Ordinary beams are usually manufactured according to IPE and INP standards, produced, and used in the Iranian market. These differences are evident in the appearance of the product. Similarly, its beams are produced in three super heavy HEM (heavy wide spar used least in Iran), heavy HEB (most used in Iran) and HEA styles. The only differentiating factor among the three categories is the thickness of the beam. The main difference between the two beams is their appearance, which can be easily identified by visual inspection. The anatomy of the product is formed by the combination of the two wings of the product, which are connected to each other with a net. Typically, the size of the wing or flange is equal to or less than half the size of the beam. Wings in hash beams have a greater thickness and width than normal beams, so hash beams are used in applications that require very strong beams. The product also has the ability to carry more loads, while being more resistant to shear forces and the wing's strength against bending forces, which is why it has numerous applications. You can identify the beam of a wing by the width of its cross-section, not to mention that the width of the wing increases the bending resistance of this product. Architects use this width as vertical supports or columns in buildings. Another point about these products is that regular beams are used for 30-meter-long applications while their beams are used for 100-meter-long applications. The most fundamental difference between ordinary beams and their beams is the internal stress of these products, which is caused by temperature differences in the production process and the ambient temperature of the equipment, where the beams can bend and tighten at the joints. This is a long-standing concern of activists in the field, inventing new equipment and techniques that can produce steel beams with desired dimensions and more precise dimensional tolerances. 
Joist price per kg
The use of various roofs in the construction industry has increased in recent years and the price are calculated per kg. joist roofs are one of the most popular and are highly valued. A block beam is a combination of beams and blocks of cement or clay. A building block is a rectangular piece measuring 40x20x25, made of concrete or clay. Blocks cannot withstand high pressure and load and break easily. If the load on the roof is too high or there are large openings, 25 cm high blocks should be used. Sometimes, in roofs that need to be thicker and require more calculations, two-part blocks are used to facilitate the work. By stacking the blocks together, they reach a height of 35 cm. Because the blocks are tongue and groove, put them together and you get a complete product. Block benefits and features The lower the block weight used, the lower the dead load of the roof and the stronger the block beams. The blocks have upper and lower surfaces, and the upper surface of the concrete includes these blocks. Concrete undersides are also dedicated to flower arrangements, plastering and stucco. Another important point about blocks is that their suction must be between 13% and 20% because above this amount it will absorb all the water in the mortar and as a result, it will spoil. 
History of making block beams It can be said that the block beam system has created a new perspective in the construction industry. Block beam systems have been introduced to the industry for about seven decades. In Iran, the use of block beams and their use goes back forty years. If you look at the buildings of Iranian buildings fifty years ago, you will notice that most of their roofs are built in the form of arched arches. Over time and scientific advances in civil engineering, the vaulting method became obsolete and was replaced by block beams. The advantages of block beams make them used in the roofs of most buildings today. In the initial phase of the block beam roof, the roof load was too great due to the use of heavier cement blocks. On the other hand, the use of cement blocks was not cost-effective, so to solve this problem Styrofoam was replaced by cement blocks. The used Styrofoam also has problems like thick smoke when it catches fire, and finally to solve this problem Styrofoam is replaced with fireproof foam. 
H beam per kg
H beam is the base of every house and has a very important role in strengthening the building. The first production of IPB or H-beams is considered one of the most important achievements of the production cell, as its production brought about a huge change in the steel industry that could quickly surpass the rest of the industry. At a distance When this iron beam factory sought innovation and transformation in the steel industry at the beginning of the 20th century, it was able to achieve this through innovation and production at H beam. The I-beam was invented and produced before the wide beam, but its wide beam was considered a very important invention and was even used on the company logo. At first, ordinary logs were mainly produced in the form of long branches, which were popular due to their fire-retardant properties compared to wood, but failed several times due to their excessive size. Finally, in 1856, when Trenton produced the first high-quality steel beams for the Federal Building, there were no previous failures, which is considered a turning point in the production and rolling of iron beams. IPE beams or I-beams have been used in the construction industry for a long time as basic material, with its successful entry into the market at the beginning of the 20th century, was able to achieve a very important in other similar goods status and was widely used in the construction of bridges and skyscrapers. 
The company's H-beam line is very large, producing wide beams up to 36 inches or 91.44 centimeters. Due to its high demand and popularity in the United States, prices for the wide spar the company produces have increased. Also during the First World War, its broad-winged arrows were widely used as materials for warfare. IPB beam = HEB, HEA, or wide spar, also known as Hash in the market, there are two kinds of light wide wing and heavy wide wing. The best-rolled section for columns is IPB wide spar or square box, as it is better than other sections in terms of resistance, also beams are easily attached to them in most construction conditions. An H-beam is a bracket for a wide beam or wide wing (like H) with longer wings than an IPE beam. The wing size of this profile is equal to its height and its simple section is used to prepare the columns. It is also used to prepare beams and rafters. The profiles are available in lengths between 8 and 16 meters and heights between 100 and 1000 mm. The HEB spar is heavy, which means that the blades of this wide spar are thicker than the HEA spar. Belts of this type are prepared and produced according to DIN 1025 - Euronorm 53-62 - EN 10034 - EN 10163-3, C - STN 42 5550ČSN 42 5550 - TDP: STN 42 0135. Its beams are ST37, ST44, ST52, and other grades used in bridges, towers, dams, and other industries requiring high strength.
