The chemical laboratory works to monitor, monitor and examine the primary raw materials entering the production processes and ensure their conformity with approved requirements. The specialists in the chemical laboratory also work to monitor the production processes in the steel smelting unit by examining and testing the chemical composition of the molten iron and steel using (spectrometer) and based on the results, the process of controlling the quality and grade of steel iron is carried out by implementing the necessary chemical treatments and determining the quantities of iron alloys to be added.
The mechanical laboratory was established to examine and test the final products of rebar and ensure that all mechanical properties of the rebar products are fully consistent with the approved specifications locally and internationally. The specialists in the mechanical laboratory also work to monitor the production processes in the steel iron rolling unit by examining The mechanical properties of the rebar are monitored using the (UTM), and based on the results, the process of controlling the quality and grade of the rebar products is carried out by implementing the necessary heat treatments.
As part of the company's commitment to providing high-quality products, Al-Mukalla Iron and Steel Company Limited adopts the best scientific and practical practices associated with the quality assurance system according to the following stages:

Al-Mukalla Iron and Steel Company Limited, in all its technical and administrative operations, is fully committed to local and international standards, specifications and standards, starting with the applicable and effective ones, starting with following general quality policies, specifications and standards that are compatible with the highest quality standards approved locally and internationally, through to defining executive work procedures in accordance with the latest technologies used in the iron and steel industry, as well as Designing and implementing quality plans that ultimately lead to obtaining products that fully conform to the highest specifications and achieve the aspirations of all customers and partners.
The process of selecting raw materials entering the production process is carried out by ensuring their sources of production and supply and that they conform to all conditions and specifications related to the systems of the Yemeni Standards, Metrology and Quality Control Organization, as well as the required conditions and specifications that are compatible with the company’s production processes and means, such as (purity, chemical composition, and form). Physicists, etc.), and suppliers of raw materials are not approved unless the suppliers commit to providing a laboratory analysis certificate for the materials and verifying the results of the analysis by conducting tests on the raw materials in the company’s laboratories.

The quality control process is carried out through the latest technology applied and present as part of the production line. At the stage of producing raw steel (steel billets), the molten steel is transferred from the electric induction furnaces to the refining furnaces, where a technology designed to maintain the purity of the steel is used. The steel is purified in refining furnaces, and the necessary alloying elements are added and stirred with inert gases to achieve uniformity of composition and adjust the temperature necessary for the casting process. Thus, strict control of the chemical composition and its homogeneity is achieved with the lowest possible level of impurities.
The quality of Al-Mukalla Iron and Steel Company Limited's products is tested throughout the entire production process, starting from the melting, casting, and rolling stages, all the way to the final product. In this context, the necessary samples are taken and subjected to testing in our own laboratories, using advanced analytical devices and modern technologies to confirm the chemical content, mechanical properties, and general shape specifications. The factory is notified directly of the results of these tests to make precise adjustments if necessary to continue maintaining the most accurate specifications and standards

As part of the company's endeavor to ensure that quality tests adhere to the highest standards of reliability and credibility, the company has invested heavily to establish modern laboratories equipped with the latest technologies and the most accurate measuring devices that are calibrated periodically to ensure the accuracy of the tests. Analysis and inspection during production processes, starting from receiving raw materials, through chemical analysis of molten steel, and ending with mechanical tests of rebar.
The final rebar product is subjected to a set of mechanical tests to ensure its compliance with all standards contained in the Yemeni standard and international specifications, in order to ensure the solidity and homogeneity of the final products. These tests include tensile stress, elongation, cold bending and general product shape tests.
