Material	Key features	Common Uses
Stainless Steel	High corrosion resistance, polished finish, long-lasting	Marine, chemical, and food processing industries
Carbon Steel	High tensile strength, cost-effective	Oil & gas, structural frameworks
Cast Iron	Very rigid& heavy, prone to rust if not coated	Drainage, water mains, and underground pipes
Alloy Steel	Enhanced with elements like chromium/molybdenum for high-performance	Nuclear, aerospace, and high-stress pipelines
Galvanized Iron(GI)	Zinc-coated for rust protection	Outdoor pipeline fencing for water supply
