Wholesale Galvanized Coil Products 0.14mm-0.6mm Galvanized Steel Coil/sheet/roll Z275 Price Of Galvanized Iron Per Kg

Product Description

1. Word Breakdown
galvanized /ælvnazd/ - coated with zinc
steel coil - steel strip coil
2. Product Definition
Coiled steel with a layer of pure zinc coated on hot-rolled or cold-rolled steel substrate. It achieves anti-corrosion effect via water barrier and sacrificial anode protection, serving as cost-effective anti-rust steel material. Industry abbreviation: GI Coil
3. Two Main Production Processes

Hot-dip Galvanized Steel Coil (HDG) The steel strip is immersed in molten zinc liquid, featuring thick zinc coating (Z40~Z350 g/), strong coating adhesion and excellent outdoor weather resistance. Widely used in construction, photovoltaic and steel structure industries. Common grades: DX51D+Z, SGCC, S250GD+Z


Electro Galvanized Steel Coil (EG) Ultra-thin zinc coating formed by electrolytic plating with smooth and bright surface. Mainly applied to home appliance casings, precision sheet metal and indoor components. Common grade: SECC

4. Key Features
Anti-rust performance: Zinc corrodes preferentially to protect the steel base when the coating is scratched;
Easy processing: Available for bending, stamping, slitting, and as substrate for prepainted steel (PPGI);
Surface types: Regular spangle, minimal spangle, zero spangle (ideal for painting);
Surface treatments available: Passivation, anti-fingerprint coating to prevent white rust.
5. Main Applications
Construction: Roof panels, wall corrugated sheets, air ducts, light steel keels, guardrails;
Home appliances: Air conditioner housings, washing machine cabinets, electrical control cabinets;
Automobile: Chassis parts, carriage sheet metal;
Others: Livestock farming equipment, pipelines, storage racks, raw substrate for prepainted steel.
6. Distinction of Similar Steel Products
Galvanized (GI): Pure zinc coating
Galvalume (GL): 55% aluminum + 43.4% zinc + silicon coating, superior heat resistance and UV resistance
Galvannealed (GA): Alloyed zinc coating produced by post-galvanizing annealing, outstanding paint adhesion
7. Common Foreign Trade Sentences
We supply hot dipped galvanized steel coil Z275.
The galvanized steel coil is used for roofing sheets
