GPH LAB
GPH Ispat, one of the leading steel manufacturers of Bangladesh, features a state-of-the-art laboratory to ensure the highest quality of finished product.
The laboratory boasts of various sophisticated testing equipment and machines such as, Universal testing machine (UTM), Bend & Re-bend testing machine, Profilometer, digital microscope, metallurgical microscope, hardness testing machine, impact testing machine etc. for accurate and precise measurements of physical and mechanical properties of Finished Product. Moreover, a very sophisticated & latest model of Spectrometer LAVM12 is used for continual analysis of chemical composition of various stages of manufacturing for Elemental Analysis and XRF (Xray Fluorescence) is used for analysis of various types of raw materials (like Lime, Dolomite, Ferroalloys etc.) and by products (like Slag, Dedusting Dust etc.). In running condition, finished product samples are tested here in regular intervals. Yield strength, ultimate tensile strength, TS/YS, Elongation at maximum force (Agt) and Elongation after fracture (A5) are measured using the UTM machine (WANCE HUT206D - 2000KN). Rib geometry measurements are conducted by Profilometer minimizing human interaction, hence eliminating human error. Bend and Re-bend tests are performed to ensure satisfactory bend and re-bend properties of finished product. Tempered martensite ring, the iconic feature of Thermo mechanically Treated (TMT) bar, is analyzed here by a digital microscope. Besides, various metallurgical analysis such as grain size analysis, phase analysis, inclusion analysis, hardness test, impact toughness test (for section product) etc. are also performed periodically. The laboratory also has access to the live feed of close circuit camera of a few areas of rolling mill crucial for quality assurance. Digital record of each test is preserved and uploaded in Level-2 web server. Finally, all the tests and analysis are compiled and documented heat-wise as the Daily Quality Control Report for ready reference. GPH Lab provides Manufacturer Test Certificate (MTC) with every delivery of finished product reassuring customers of the highest quality GPH Ispat pledges of.
Recognized Lab
here are multiple recognized labs in Bangladesh (like BUET, KUET, CUET, RUET, SUST, MIST etc), among which BUET materials testing lab is the most popular one.
BUET provides testing service on different aspects of materials including full range of chemical, physical and mechanical and other properties analyses, microstructural analysis, heat treatment, corrosion tests, failure analysis etc. to public and private organizations with utmost precision and moral ethics. That’s why many customers prefer BUET labs as the epitome of assurance.
In this regard, GPH Ispat tests the finished products at BUET materials testing lab in a monthly basis. Samples of all finished product are sent to BUET for chemical and mechanical analysis and after testing they issue a certificate to reassure that all requirements are met as per standards. These certificates are well documented in their designated folder and kept for future reference. This also serves as a quality benchmark against competitors’ products in the market, hence ensuring customer satisfaction.
GPH Ispat Limited is one of the leading integrated steel manufacturing companies in Bangladesh engaged in the manufacturing and trading of M. S. Billet and M. S. Rod.
