Choose your metal based upon your strength and aesthetic requirements. Regardless of which metal you choose, all our metals have the same load ratings. However some metals are more rigid than others - you can check this if you were to press your finger on a pegboard 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.
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.
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.
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 finishes.
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.
For most general pegboard applications, our standard metal gauges (thickness) are adequate. If your pegboard will be holding heavier loads or in a heavy-use application, consider upgrading to thicker gauges.
