Saudi Market Recommendation
Recommended: Copper-Bonded Steel + 316L Stainless Steel Combination
Based on actual project experience in Saudi Eastern Province (Persian Gulf coast) and inland desert regions, we recommend: 20% IACS copper-bonded steel for main grounding body (excellent lightning current conductivity due to skin effect, best cost-performance), 316L stainless steel for connectors and surface equipment (best salt-spray corrosion resistance). This solution has been validated in multiple Aramco projects, compliant with SAES-P-111 standard.
