A bridge that is resistant to corrosion and degradation from surrounding mediums, made by surface treating steel plates or using corrosion-resistant materials like stainless steel 201, 304, 316, etc.

Note: Corrosion resistance is divided into three types: metallic inorganic VCI coating, organic coated steel, and stainless steel material. The metallic inorganic coating offers long-lasting protective effects, resists UV aging, and is suitable for indoor and outdoor environments with moisture, salt mist, and other chemical gas corrosion. The organic coated steel, due to its good molecular chemical stability, is resistant to acid and alkali corrosion, but has poor resistance to UV aging and is mainly used indoors, not suitable for outdoor conditions.

The energy-saving standard for cable bridge trays with corrosion resistance references GB/T 23639—2017 "Energy-saving and Corrosion-Resistant Steel Cable Trays." The material-saving rate standard for corrosion-resistant cable trays must be greater than or equal to 20% to meet the standard. The energy-saving rate standard for corrosion-resistant cable trays must be greater than or equal to 1.0 to meet the standard.

The bridgeway energy-saving efficiency test is conducted in accordance with the provisions of Appendix C of GB/T 23639—2017 "Energy-saving and Corrosion-resistant Steel Cable Bridgeways."
