For over 50 years, Q-Panel steel and aluminium test substrates have been recognised as the world standard for a consistent and uniform test surface for paints, plating, adhesives, sealants, rust inhibitors and other coatings. Thousands of labs around the world use millions of our steel and aluminium test panels every year for colour development, weathering exposures, salt spray and corrosion testing, physical properties testing and quality control.

The use of weathering panel substrates allows for consistent and controlled testing, as the substrate provides a known and stable background for evaluating the performance of the product or material. This is particularly important for evaluating changes in the appearance or colour of materials after exposure to environmental conditions, such as light, heat, or moisture.

A wide range of panel sizes and types are available for immediate shipment from stock. Look for the Q-shaped hole. It's our trademark and your assurance of quality.
