Why Steel Sign Frames Need Coating
The Rust Problem
Steel is strong but can rust when exposed to water or air. Rust damages steel and makes it weaker over time. بدون حماية, steel sign frames can break and stop working properly.
Protective coatings are important because they block rust-causing elements. على سبيل المثال, uncoated steel like ASTM A-36 loses strength quickly due to rust. Coated steel, such as those with Zn-Ni-Cu or Zn-Ni-Cu-TiB2, stays stronger and resists rust better. These coatings also stop bacteria from speeding up rusting.
