Who can tell me the complete specifications and models of steel? This article is the model introduction just now, you can refer to it. Hope this helps you
Steel for construction can be divided into steel for steel structures and steel for civil construction. The steel materials used for steel structures are mainly low alloy steel (Q345 series) and ordinary structural steel (Q235 series) plates. Some important structural designs require steel to use materials with Z-direction performance requirements such as z15, Z25, and Z35. The main structure of light steel mostly uses Q235 material, the main structure of heavy steel mostly uses Q345 material, the embedded anchor bolts mostly use Q235 round steel, the tie bars are mostly hot-rolled steel bars, and angle steel, channel steel, H-shaped steel and other shaped steel are also used in small quantities. . Civil construction steel materials mainly include rebar, round steel, wire rod and section steel.
1. Rebar
The grade of hot-rolled ribbed steel bar is composed of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the words Hotrolled, Ribbed, and Bars respectively. Hot-rolled ribbed steel bars are divided into three grades: HRB335 (the old brand is 20MnSi), HRB400 (the brand is 20MnSiV, 20MnSiNb, 20MnTi), and HRB500.
Steel bars for reinforced concrete refer to straight or disc-shaped steel materials used for reinforced concrete reinforcement. Their shapes are divided into two types: plain round steel bars and deformed steel bars. The delivery state is straight bars and disc round steel bars. kind. Plain round steel bars are actually small round steel and discs of ordinary low carbon steel. Deformed steel bars are steel bars with ribbed surfaces, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. There are three shapes of transverse ribs: spiral, herringbone, and crescent. Expressed in millimeters of nominal diameter. The nominal diameter of deformed steel bars is equivalent to the nominal diameter of plain round steel bars with equal cross-sections. The nominal diameter of steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm.
Steel types: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Steel bars in concrete mainly bear tensile stress. Due to the role of ribs, deformed steel bars have greater bonding ability with concrete, so they can better withstand external forces. Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
Product standards: (GB1499-1991, BS4449:1988)
Specifications: 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 50mm
Vanadium-containing new Grade III threaded steel bars (20MnSiV, 400Mpa) are added with vanadium, niobium, titanium and other alloys during the production process. Compared with ordinary Grade II threaded steel bars, they have higher strength , good toughness, good welding performance and earthquake resistance. In the construction market of developed countries such as Europe, Grade III rebar accounts for 80% of the total rebar. In my country, the former Ministry of Metallurgy and the Ministry of Construction jointly issued a document to promote its application in 1995. The Ministry of Construction incorporated the technical conditions of the new Grade III threaded steel bars into the national standard GBJ10-89 "Code for Design of Concrete Structures".
Advantages of vanadium-containing Class III threaded steel bars
A. Economical: Due to its high strength, the use of new Class III threaded steel bars can save 10-15% of steel compared with Class II threaded steel bars, so it can Reduce construction costs of construction projects.
B. High strength and good toughness: using micro-alloying treatment, the yield point is above 400Mpa and the tensile strength is above 570Mpa, which are 20% higher than Class II threaded steel bars respectively.
C. Earthquake resistance: Vanadium-containing steel bars have higher bending resistance, aging performance, higher low-cycle fatigue performance, and their earthquake resistance is significantly better than Class II threaded steel bars.
D. Easy to weld: Since the carbon content is ≤0.54%, it has good welding performance, adapts to various welding methods, and the process is simple and convenient.
E. Convenient construction: The use of new grade III threaded steel bars increases the construction gap, ensuring convenient construction and construction quality.
2. Round steel
Round steel refers to a solid long steel bar with a circular cross-section. Its specifications are expressed in millimeters of diameter. For example, "50" means a round steel with a diameter of 50 mm. Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: small round steel of 5.5-25 mm is mostly supplied in straight strips and bundles, and is often used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used to manufacture mechanical parts or seamless steel pipe blanks. Calculation method of theoretical weight of steel (unit: kilogram) round steel: weight per meter = 0.00617*diameter*diameter (the same as rebar and round steel)

Naming a steel trading company is a very particular matter, and it is also a major event. It is related to the future development of the company. I suggest that some professional naming people be hired. Better.
A few things to note when naming your company:
1. Will it sound easy to pronounce and easy to remember?
2. Be consistent. The company name is not similar and will not be confused.
3. The meaning of the word is beautiful and consistent with the company's image
4. The name and the industry image will not make people feel contradictory. .
5. Within one second, let people know what the product is selling.
Must-read when choosing a name:
1. Arrange the eight characters, analyze the prosperity and decline of the fortune, and determine the use of gods as the basis for naming. (What is Yongshen? Yongshen is the five elements in the Bazi or the Grand Luck that play the most important role in the balance between the strength and weakness of one's daily stem, also known as the life master, and the soul. It plays a role in supplementing and rescuing the life master. Finding the right gods to support those who are too weak and suppress those who are too strong will play a vital role in the entire destiny. Using the wrong gods to compensate for the negative will not only fail to help people, but the consequences will be more serious. It can really harm people's lives. ).
2. The configuration of the three talents of heaven, earth and man should be mutually beneficial and avoid mutual restraint. If the three talents are not configured well: it will have a bad impact on basic luck, luck, health, and family.
3. The pronunciation of the words should be beautiful and catchy, and avoid too strong a tone.
4. The meaning of Chinese characters should be elegant, and names that are too vulgar, too crazy, or too Westernized should not be used.

Theoretical weight calculation of steel
The unit of measurement for calculating the theoretical weight of steel is kilogram (kg).
The basic formula is:
W (weight, kg) = F (cross-sectional area mm2) × L (length, m) × ρ (density, g/cm3) × 1/1000
