Introduction to Steel Deformed Rebar in Coil
Steel Deformed Rebar In Coi-1 | |
| Steel Deformed Rebar In Coil is a kind of wire steel, which is characterized by spiral cross ribs on the surface, and usually appears in the form of disc-shaped coils and bundles. The advantage of Steel Deformed Rebar In Coil is that it can be cut into any length according to demand, which is suitable for steel bars with smaller diameters (usually less than 10mm), and needs to be straightened when used. Generally, the ones on the market are 6.5-8.0-10-12-14, which are all construction steel. | |
| 1. Steel Deformed Rebar In Coil model symbol | |
| The coil model symbol is a symbol in the coil model marking system. Its main function is to distinguish various types of coils. Coil model symbols usually consist of letters, numbers and special symbols. Different symbols represent different sizes, shapes, materials and other information. The coil model symbol is a very important part of the coil marking system. Its correct application can effectively avoid safety hazards caused by misuse of models. Therefore, when using coils, pay attention to correctly understand the meaning of the coil model symbol to avoid using the wrong model. | |
| (1) The coil model symbol generally contains one or more letters. Used to identify the material of the coil. Common material letter codes are: A: Aluminum B: Brass, Copper C: Carbon Steel, Cold Rolled Steel Plate F: Stainless Steel, Acid-Resistant Steel H: High Strength Steel, Alloy Steel L: Aluminum Bronze M: Martensitic Stainless Steel S: Ordinary Steel, Low Carbon Steel T: Titanium For example, the coil model symbol "FH-10" has "F" representing stainless steel and "H" representing high strength steel. | |
| (2) Numbers represent dimensions The numbers in the coil model symbol usually represent the dimensions of the coil, such as diameter, height, etc. For example, a coil with the coil model symbol "M5" represents a coil with a diameter of 5 mm. | |
| (3) Special symbols indicate other information Various special symbols in the coil model symbol can also indicate other information of the coil, such as shape, surface treatment, etc. For example, the "+" symbol indicates a coil with treated surface, while the "-" symbol indicates an untreated coil. | |
| 2. Common specifications and models | |
| HRB335 | The yield strength is 335MPa, with good plasticity and welding properties, suitable for general building structures such as residential buildings, office buildings, etc. |
| HRB400 | The yield strength is 400MPa, which is higher than HRB335 and is suitable for structures with higher strength requirements, such as high-rise buildings, large-span bridges, etc. |
| HRB500 | With a yield strength of 500MPa, it is a representative of high-strength steel bars and is suitable for structures with extremely high requirements for strength and toughness, such as large public buildings and special projects. |
| CRB550 | The yield strength is 550MPa, with high strength and good plasticity, suitable for prestressed concrete structures and thin-walled components. |
| RRB400 | The yield strength is 400MPa. Through the residual heat treatment process, it has good comprehensive mechanical properties and welding properties and is suitable for various building structures. |
