Steel and iron signs have become increasingly popular due to their durability, classic aesthetic, and versatile applications. Whether used for business branding, street signs, or decorative purposes, these metal signs are built to withstand various conditions. But the question remains: do steel and iron signs hold up in the elements? In this blog post, the experts from Liston Metalworks break down how these materials perform when exposed to rain, snow, sun, and other environmental factors.
Durability of Steel & Iron Signs
Both steel and iron are incredibly durable materials, which is one of the reasons they’re often chosen for outdoor signage. Steel, especially galvanized steel, is known for its ability to resist rust and corrosion. Galvanization is a process where a layer of zinc is applied to steel, making it more resistant to water and environmental elements. Similarly, cast iron is naturally resistant to wear and tear, but it requires more maintenance compared to steel. While these materials are tough, their longevity depends on how well they’re treated and maintained. For instance, steel signs that have been powder-coated or treated with a rust-resistant finish can last for many years without showing signs of wear. Iron signs, however, tend to rust more easily without protective coatings. Over time, rust can degrade the sign, especially in humid or coastal areas where the salt in the air accelerates corrosion.
Impact of Weather Conditions on Outdoor Metal Signs
Weather conditions play a significant role in the lifespan of steel and iron signs. Here’s how these metals hold up to various elements:
Rain and Snow: Steel and iron can withstand heavy rain and snow, but prolonged exposure to water without proper drainage or protective coatings can lead to rusting. Regular maintenance, like cleaning and applying rust inhibitors, can help prolong the life of the signs in wet climates.
Sun Exposure: The sun’s UV rays can cause fading in painted or coated metal signs over time. This is especially noticeable in areas with intense sunlight. To prevent this, using UV-resistant coatings on the signs will help maintain their color and finish.
Wind: High winds are typically not a concern for steel or iron signs due to their heavy nature. However, if a sign isn’t properly secured or mounted, it can become a hazard. Ensuring that the sign is installed with the right mounting hardware is key to preventing damage from strong winds.
Metal Sign Maintenance & Care
One of the key factors in ensuring that your steel or iron sign holds up in the elements is regular maintenance. Cleaning the sign periodically helps prevent dirt and debris buildup, which can trap moisture and lead to rust. Additionally, reapplying protective coatings or touch-up paint is important to maintain the sign’s appearance and integrity. For iron signs, it’s particularly important to inspect for signs of rust and treat it as soon as it appears. There are rust-removal products and paints specifically designed for metal surfaces that can help restore the sign’s appearance.

Steel and iron signs can hold up quite well in the elements, provided they are properly maintained. While steel is generally more resistant to rust and corrosion than iron, both materials offer long-lasting durability for outdoor signage. By using protective coatings, regularly inspecting the signs, and performing necessary maintenance, you can ensure that your steel or iron sign continues to look great and withstand the test of time.
