Q-Panel Paint Test Panels

Q-Panel S Steel Panel 3 x 5" pk/250
Type S Steel Q-Panels are ground polished finish steel panels. They are the same steel as Type R, but one side is polished by grinding it with an abrasive until the mill surface is completely removed. This imparts a smooth surface that looks similar to a “brushed” finish. The ground (or polished) surface frequently gives better adhesion results than a matte finish.
Features
- Q Panel brand test panels minimize metal variability in coatings tests.
- These spray-out cards are available in various sizes and finishes.
- 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 and Steel panels available:
- Aluminum - Made from high quality aluminum, they are clean, consistent, convenient, and economical. Being lightweight and rust free makes them more convenient to use in place of steel for sales samples, color standards, mailing and even for weathering tests. We offer Bare Aluminum Panels (A) and Chromated Panels (AL).
- Steel - Made from standard low-carbon, cold-rolled steel, with ASTM A 366, A 109 and QQS-698. They are clean, consistent, convenient and economical. We offer Types QD and DT (Smooth Finish), Type R (Matte Finish), Type S (Polished Finish) and Taber Abrasion Panels specially designed for the Taber Abraser.

Taber Panel: 4 x 4" (101 x 101 mm) and 0.032" (0.81 mm)0.010" (0.25 mm) Surface Finish: Smooth
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.Dull Matte
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.Ground
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.Tinplate
Tin-plated with bright reflow finish. This type is required by some government standards.Temper: 1/4 hard T2 Hardness (Rockwell B): 50-65 Tensile Strength (MPa): 310 - 448 262 - 400 Carbon (%): <0.15 Manganese (%): <0.60 Phosphorus (%): <0.03 Sulfur (%): <0.035
