Brand Story
The main concept behind the Metal Testing Brand is to portray the laboratories royal heritage through simple minimalist symbols. When we look at the emblem, we first notice its shield shape, which symbolizes the security and strong foundation of the company. Moving from the top we come across a crown symbol representing heritage, the next is a diamond between two microscopes located in the middle of the shield as the main symbol of the company and a representative of the industry in which the company is located. In the lower part of the shield, there are two crossed keys that symbolize knowledge and stability .Behind the company, as a large part of the brand, there two colors and they are deep dark green and a gradient of golden shades. In order to reach their full potential, they are used together with a pattern composed of a crown symbol located at the top of the emblem.
Accreditation
Our laboratories are accredited by the Gulf Accreditation Center (GAC) on ISO/IEC 17025. This accreditation certifies that we meet the general requirements for the competence of testing and calibration laboratories. Also, GAC is a full member of ILAC - the International Laboratory Accreditation Cooperation. This means that any testing report that is certified by our laboratory is recognized around the world.
