AVS Industries manufactures a diverse portfolio of hot work protection fabrics. Select the hot work (welding) protection fabric that meet your needs!

Hot work operations apply to all riveting, grinding, welding, flame cutting or other fire or spark-producing operations. These processes typically require special permits and procedures to prevent the ignition of vapors, liquids and solids that may be in or near the work area. E-Glass based Fiberglass and Silica (>95% SiO2) fabrics are the two types of protection fabrics typically used for hot work operations. A brief review of the fabrics is provided below.
