Manufacturing factories use valid Iranian and foreign standards to make all kinds of ribbed rebar; However, the quality of ribbed rebar from some factories is still better than others. There are 3 main reasons for this. First, professional factories comply with all the standard defined components in the production process of their ribbed bars. Meanwhile, some manufacturers, for whatever reason, implement only a few specific parameters. The next reasons are related to paying a lot of attention to the weight of the rebar and its standard length in each bandil.
Quality of ribbed rebar
This quality affects the entire project under construction or repair, and any defect in its structure causes personal and financial damage to the consumer. In other words, one of the reasons for the purchase of ribbed rebar by consumers is their excellent quality and mechanical properties. Therefore, the consumer expects his purchased rebar to have the best possible yield and tensile strength. The steel market is also a big and very competitive market, and of course, low-quality ribbed rebars have no chance to compete with other rebars offered in the market, and their sale will fail even at a cheap price. On the other hand, high-quality ribbed rebars will have a good fortune not only in the Iranian market but also in the world.
High Quality Ribbon Production Standards
The importance of the quality of ribbed rebar has led to the use of the best international standards by skilled and experienced manufacturers. In the following section, the names of the most important standards of high-quality ribbed rebar are given: 1. European standard EN 2. Japanese JIS standard 3. German DIN standard 4. ISO global standard 5. American ASTM standard 6. Iranian rebar standard with number ISIRI 3132 7. Russian standard (A2, A3 and A4 ribbed rebars are produced according to this standard.)
The methods of identifying the quality of the rebar rebar
In the following section, the methods of detecting the quality of ribbed rebar are given:
Checking the surface of ribbed rebar
By examining the surface of the ribbed rebar, you can understand its quality. High-quality ribbed bars do not have scratches and rot and have a dark color. Any discoloration or rust in new rebars means their low quality.
Existence of an abbreviation in the body of ribbed rebar
High quality ribbed rebars with an abbreviation are on their bodies. This mark contains information about the production style and tread type. At the same time, abbreviations are engraved in a prominent form. Even the way of engraving abbreviations indicates its quality or not. Having an identification plate or technical certificate
Each bandil contains several bars and comes with an identification plate. The information recorded in the plate indicates the quality level of the product. Therefore, by studying the specifications included in the Bendil license plate, you can understand its quality.
Checking the analysis sheet or quality control certificate of ribbed rebar In addition to the identification plate, ribbed bars also have an analysis sheet. This sheet explains all the tests done on the rebar along with its technical and general characteristics. By reading the analysis sheet, you can understand the quality and resistance of the product.
Summary The production of all types of ribbed rebar should be based on approved domestic and foreign standards so that their quality reaches the desired level. In fact, the importance of the quality of ribbed rebar is not hidden from anyone! This rebar has important applications in building construction and it must have the necessary quality to be used in the structure. Its poor quality endangers people's health and causes financial damage to the builder. Therefore, one of the most important tasks in construction is to buy high-quality rebar.
