Product Description
GI Coil is the industry shorthand for hot-dip galvanized iron coil, a mill-form steel product widely traded in commodity steel markets. Manufactured by immersing cold-rolled strip in molten zinc, GI coil carries a metallurgically bonded zinc layer that prevents red rust on exposed surfaces. Standard regular spangle finish is applied across a thickness range of 0.085mm to 1.2mm and a coil width of 700mm to 1250mm. Buyers specify zinc coating weight from 20g/m² to 300g/m² to match inland, coastal, or industrial service environments. The coil format allows high-volume handling, slitting, and cut-to-length conversion at downstream service centers. Each mill lot can carry an identification stamp for lot traceability.
For wholesale and commodity buyers, supply stability and container-ready loading matter as much as price. With monthly output around 10,000 tons and an in-house hot-dip galvanizing line, we consolidate repeat GI coil orders into continuous production runs, keeping unit cost competitive and delivery predictable. Standard specifications ship from tens of meters upward, and every export lot is packed with waterproof film, rubber spacers, and steel banding before container loading, with a loading video supplied for shipment records.

Applications
1. Steel Service Centers and Traders - GI coil is purchased in mill quantities and resold after slitting or cut-to-length conversion, where consistent coil weight and width tolerances keep downstream processing efficient.
2. Wholesale Roofing Material Distribution - Distributors stock regular spangle GI coil for rapid conversion into corrugated roofing, because the zinc coating survives outdoor storage and site exposure before installation.
3. General Steel Fabrication Supply - Medium-volume fabricators buy GI coil as a cost-effective pre-galvanized base material, avoiding the lag and cost of post-fabrication hot-dip galvanizing.
Customization
Standard GI coil specifications cover thickness 0.085–1.2mm, width 700–1250mm, and zinc coating 20–300g/m². We accept OEM and ODM orders and can produce to customer drawings or samples, with mill identification stamps available. Custom lots undergo first-piece confirmation before batch production, and samples can be arranged on request.
Packaging & Transportation
Each export bundle is wrapped in waterproof film, separated with rubber spacers between coils, and secured with steel band strapping. Wooden reinforcement inside containers prevents movement during ocean transit. Pallet loading is available on request, and a loading video is recorded for every shipment. EXW is our preferred trade term.
FAQ
Q: What is your minimum order quantity for GI coil wholesale?
A: Standard GI coil orders start from tens of meters. The MOQ is designed to let distributors and small fabricators trial a lot before scaling up; larger repeat orders qualify for better unit pricing.
Q: Do you accept OEM or custom specification orders?
A: Yes. We run OEM and ODM production and can manufacture to customer drawings or samples. Our technical team reviews every drawing before production, and the first piece is confirmed with you before batch output begins.
Q: How are GI coils packed for export?
A: Export packs use waterproof film wrapping, rubber spacers between coils, and steel band strapping, with wooden reinforcement inside containers. Pallet loading is optional, and we provide a loading video for every container. EXW is our standard trade term.
