Product Description
Hot Dip Galvanized Steel Coil is manufactured by passing cold-rolled steel strip through a molten zinc bath, forming a metallurgically bonded zinc-iron alloy layer that delivers durable corrosion protection. Our regular spangle coils display visible crystalline zinc patterns across the surface, with thickness ranging from 0.085mm to 1.2mm and width from 700mm to 1250mm. Zinc coating weight is adjustable between 20g/m² and 300g/m², enabling buyers to match corrosion resistance to their specific environmental conditions. The coil form supports efficient downstream processing including cut-to-length sheeting, corrugated roll forming, and slitting into narrow strips. Each coil can be produced with an identification stamp for traceability.
For buyers sourcing galvanized coil in volume, production consistency directly affects downstream yield. Our in-house hot-dip galvanizing line controls zinc coating weight and spangle formation across the full coil width, reducing material rejection during subsequent cutting and forming. When standard dimensions do not match a project's processing line, our technical team reviews customer drawings to confirm feasible thickness, width, and coating combinations before production, minimizing trial-and-error waste on repeat orders.

Applications
1. Roofing and Wall Cladding Manufacturing - The coil serves as base material for corrugated roofing sheets and wall panels, where the zinc coating protects against atmospheric corrosion in industrial and rural environments.
2. Steel Structure and Fabrication - Downstream fabricators cut and form the coil into purlins, channels, and structural components requiring consistent corrosion resistance without additional painting.
3. Automotive and Appliance Components - The thinner-gauge range (0.085–0.5mm) suits stamped parts, enclosures, and ductwork where a pre-galvanized surface reduces post-processing coating steps.
Customization
We support customization of thickness (0.085–1.2mm), width (700–1250mm), and zinc coating weight (20–300g/m²) per customer specifications. Cut-to-length dimensions and corrugation profiles can be configured to match downstream processing requirements. OEM and ODM orders are accepted, including production based on customer drawings and samples. Custom products undergo first-piece confirmation before batch production.
Packaging & Transportation
Export packaging uses waterproof film wrapping with rubber spacers between coils, secured by steel band strapping. Wooden reinforcement is applied inside containers to prevent movement during transit. Coils can be loaded onto pallets upon request. Loading videos are recorded for every export shipment. EXW is our preferred trade term.
FAQ
Q: What is the minimum order quantity for galvanized steel coils?
A: Our MOQ starts from tens of meters for standard specifications. Larger orders offer better unit pricing due to raw material consolidation and continuous production.
Q: Can you produce coils according to our required thickness and zinc coating?
A: Yes. We manufacture based on customer specifications and drawings. Our technical team reviews each drawing to confirm feasible thickness, width, and coating combinations before production begins.
Q: What is the lead time for standard and custom coil orders?
A: Standard coils typically ship within 3–5 days. Custom specifications require 10–15 days after drawing confirmation. Peak-season lead times are confirmed in advance and written into the contract.
