The lifespan of chicken cages is heavily influenced by material quality and anti-corrosion processes, especially in humid poultry farming environments. This article delves into why Q235 steel is the industry standard, compares the corrosion protection mechanisms and long-term performance of hot-dip galvanizing versus aluminum-zinc alloy coatings, and reveals how scientific material selection and routine maintenance can extend equipment life to 15–20 years—reducing replacement costs and improving ROI. Practical insights are supported by data-driven analysis and real-world case studies for farmers seeking actionable technical decisions.
