Weatherproof Qualities
耐食性
Aluminum traffic signs are very good at handling bad weather. When air touches aluminum, it makes a thin oxide layer. This layer protects the metal from getting damaged. If the sign gets scratched, the oxide layer comes back fast. This keeps the sign safe. Scientists found that this layer blocks things like chloride ions. These are found in rain and near the ocean. このため, aluminum traffic signs stay strong and look good, 厳しい場所でも.
Studies from places near the sea and factories show something important. Signs with anodized finishes last up to 40% longer than signs without it. The anodized layer makes the sign stronger and last longer. This is helpful where salt and pollution can hurt other signs. Steel can rust and get weak, but aluminum stays strong. This means aluminum traffic signs need less fixing and are a good deal for the long run.
ヒント: The oxide layer on aluminum does not fall off like rust does on iron. This helps aluminum signs stay strong and work well as weather resistant signs.
UV保護
The sun can hurt many things outside, but aluminum traffic signs do not fade or break down easily. This is because they have special UV resistance. Makers put on anodized or alodized finishes and use strong reflective films. These coatings stop bad UV rays and keep the colors and pictures from fading. Digital printing with UV-cured inks also helps the signs stay bright and easy to see for a long time.
| 環境要因 | アルミニウム性能 | 塗装された亜鉛メッキ鋼の性能 |
|---|---|---|
| 紫外線 | Maintains strength; anodized aluminum resists fading | Paint deteriorates over time and requires maintenance |
| 雨と湿度 | Does not rust or weaken from water | Paint and zinc initially protect but rust eventually |
| 塩水と沿岸空気 | Remains strong and rust-free in salty environments | Coatings degrade, leading to rust and damage |
| メンテナンス要件 | Minimal care; no repainting or rust repairs needed | Frequent inspections, タッチアップ, and repainting needed |
| 過酷な環境での耐久性 | Long-lasting with minimal weather damage | Coatings fail sooner, causing rust and replacements |
This table shows how UV resistance and weather resistance help aluminum traffic signs last longer. The coatings and finishes keep the signs strong outside and help them stay easy to see, even after many years in the sun.
Impact and Scratch Resistance
Aluminum traffic signs do more than just handle bad weather. They are light but also very strong. This makes them easy to put up and move. They can also take hits from things like wind or flying objects without getting bent or scratched.
Anodized finishes make the signs even harder to scratch. The tough coating sticks to the aluminum and does not peel off. This is important in busy places where signs might get touched or hit a lot. The signs stay strong and last a long time, even outside.
アルミニウムは軽いですが、強いです, so it does not put much weight on posts or hardware. This means less chance of breaking during storms or strong winds. The weather resistance of aluminum traffic signs keeps them working and easy to see. That is why they are a great pick for weather resistant signs in all kinds of weather.
