Material Certificates is not a specific brand but a term referring to documentation provided by manufacturers to certify the quality, composition, and compliance of materials used in industrial products. These certificates are essential in industries like manufacturing, construction, and engineering, ensuring materials meet standards such as ASTM, ISO, or ASME. Companies like Radwell International (USA) and Grainger (USA) often deal with products requiring material certificates, including electrical components, metals, and industrial supplies. The certificates are issued by material producers or testing labs, not by a single brand.
