Price (FOB China, Q2 2026)	$680-800/ton	$600-680/ton
Corrosion Resistance	Excellent - 25-50 year service life	None - requires painting
Best Applications	Water supply, outdoor structures, fencing	Indoor structures, painted applications
Welding	Requires zinc removal at weld zone	Easy, no prep needed
MOQ	5 tons per specification	5 tons per specification
Standards	BS1387, ASTM A53, EN 10255	ASTM A53, API 5L

Verdict: For outdoor or water-contact applications, galvanized pipe is the better investment despite the 10-15% higher upfront cost. For indoor structural use, black pipe offers the most cost-effective solution.
