Strength or rigidity is dependent on the type of metal but mostly dependent on the thickness of the metal. The thicker the metal the more rigid it is. You can envision this if you were to lay a sheet of the metal flat on a table. And then start to push the metal sheet off the table. How quickly would the metal start to droop and how much would it droop. In the context of a pegboard, you can see this if you were to press your finger at a point between two mounting points - a pegboard made with a more rigid metal will have less flex in and out, at this point.

Diamond Plates offer a high-performance and industrial appearance - the busy diamond pattern is excellent at hiding abuse over time. Anodized Diamond Plates are colored by a chemical process which is the most durable method to impart color onto metal, and therefore are more durable than painted colors.

Brushed Stainless Steel is the best metal available - we use the same stainless steel used on high end appliances. It's rigid and hard and is the most scratch resistant of all metals. It also has no paint that can be inadvertently scratched over time, and is suitable for outdoor and wet environments.

Brushed Aluminums can approach the looks of Brushed Stainless Steel but are softer and more susceptible to scratching over time. They are also 1/3 the weight and lower cost than Brushed Stainless Steel, and are somewhat suitable for outdoor and wet environments.

Galvanized Steel is strong and rigid with a silvery grey appearance, and has no paint that can be inadvertently scratched over time. However it is not suitable for outdoor or wet environments

Aluminum Colors offer a high grade painted surface in many bright colors, but as durable as we make the paint, it is indeed a paint and therefore susceptible to scratching over time. Anodized Finishes, however, are much more durable than painted finishes, but only available in select colors.

Steel Colors also offer a high grade painted surface in colors, but again as durable as we make the paint, it is indeed a paint and therefore susceptible to scratching over time. The Steel colors are 24GA and are one gauge thinner than our Galvanized Steel which is 22GA. Therefore unless having a color is an absolute must, Galvanized Steel is typically a better value.
