1.How do raw materials affect the price of galvanized strip steel?
Zinc ingot price: LME zinc futures dominate, zinc consumption per ton of galvanized strip = zinc layer weight (g/m²) × strip width (m) × length (m) × 0.001
Substrate material: cold-rolled coil price fluctuations
Alloy additives: aluminum, magnesium, nickel and other alloy component costs
2.How do process complexity and quality grade affect the price of galvanized strip steel?
Surface treatment level: O5 (automobile outer panel) processing fee is 300 yuan/ton higher than O3 (for construction)
Coating type: zinc aluminum magnesium (GM) costs 400-600 yuan/ton higher than pure zinc (GI)
Environmental protection passivation: chromium-free passivation (Cr-Free) costs 150-250 yuan/ton higher than traditional process
Annealing process: continuous annealing (CAL) saves energy by 80 yuan/ton lower than hood annealing (BA)
3.How do market supply, demand and regional structure affect the price of galvanized strip steel?
Capacity utilization rate: Bargaining power increases when steel mill operating rate is > 85%
Downstream industry demand: Automotive sheet
4.What impact do logistics and regions have on galvanized strip?
Transportation radius: When land transportation is greater than 500km, logistics accounts for more than 10%.
Port premium: The CFR price of galvanized coils exported to Southeast Asia is $40-60/ton higher than FOB.
Warehousing turnover: Futures orders are ¥60-100/ton lower than spot inventory costs.
5.What does the price volatility warning include?
Zinc price indicator: LME three-month zinc futures + Shanghai zinc spot premium
Steel price adjustment signal: Baosteel and Ansteel's monthly galvanized product base price adjustment range
Inventory cycle: When social inventory is greater than 1.2 million tons, prices are under pressure (critical point in 2024)
Exchange rate fluctuations: RMB depreciates by 1% → imported zinc cost ↑¥70/ton
