Q Panel brand test panels minimize metal variability in coatings tests. These spray out cards are available in various sizes and finishes, including bare steel, iron phosphated steel, bare aluminum and chromated aluminum. Panels are supplied pre-cleaned, with a 1/4" (6mm) Q-shaped hole. For safety and ease of handling, the panels have rounded corners and deburred edges.
Aluminum test substrates minimize metal variability as a source of bias in critical tests. Made from high quality aluminum, they are clean, consistent, convenient, and economical. A wide range of panel sizes and types are available and are typically in stock. Panels are stored completely clean, and in most cases can be used right out of the box. Because they are lightweight and rust free, it is often more convenient to use aluminum panels in place of steel. Aluminum panels can be used to replace steel for sales samples, color standards, mailing and even for weathering tests.
Steel test substrates minimize metal variability as a source of bias in critical tests. Made from standard low-carbon, cold-rolled steel, they are clean, consistent, convenient and economical. A wide range of panel sizes and types are available and are typically in stock. Panels are stored completely clean and, in most cases, can be used right out of the box. Steel panels are made from standard low-carbon, cold-rolled steel complying with ASTM A 366, A 109 and QQS-698.

Bright finish produced at the steel mill by rolling with smooth ground rolls. Recommended for testing gloss and color. NOT recommended for physical properties and corrosion tests.
Mill finish produced by roughened rolls. This matte finish is representative of general purpose sheet metal applications. Because they are thicker, more rigid than Type QD.
Polished Finish (one side), same steel as Type R but one side polished by grinding with an abrasive until mill surface is completely removed. Not representative of any specific steel surface normally used for painting, they are widely used because they provide a standardized surface for testing.
Tin-plated with bright reflow finish. This type is required by some government standards.
