SGCC Galvanized Steel Coil - High-Quality Hot-Dip Zinc Coated Steel for Construction

SGCC galvanized steel coil is a hot-dip zinc coated carbon steel product manufactured according to JIS G3302 standards, delivering exceptional corrosion protection and superior formability for construction, roofing, and general fabrication applications. As a mill-direct supplier with over 15 years of export experience, we provide premium grade SGCC coils with consistent zinc coating uniformity, tight thickness tolerances, and factory-competitive pricing tailored to international buyers across Southeast Asia, the Middle East, and South America.

What Is SGCC Galvanized Steel Coil?

SGCC refers to a commercial-quality cold-rolled steel substrate that undergoes continuous hot-dip galvanizing per JIS G3302:2019. The designation "S" stands for steel, "G" for galvanized, and "CC" for commercial cold-rolled. This grade features a zinc coating applied through immersion in a molten zinc bath maintained at approximately 460°C, forming a metallurgically bonded zinc-iron alloy layer that provides long-lasting barrier and cathodic protection against corrosive environments.

SGCC Galvanized Steel Coil Technical Specifications

Our SGCC galvanized steel coil is produced in strict compliance with JIS G3302:2019 and can also be cross-referenced to ASTM A653/A653M CS Type B. Below are the standard parameters:

Parameter	Specification
Standard	JIS G3302:2019 / ASTM A653 CS-B
Base Metal Thickness	0.12 mm – 3.0 mm
Coil Width	600 mm – 1,500 mm
Coil Inner Diameter	508 mm / 610 mm
Coil Weight	3 MT – 8 MT per coil
Zinc Coating Mass	Z40 – Z275 (40–275 g/m² both sides)
Yield Strength	≥ 205 MPa (typical)
Tensile Strength	270 – 500 MPa
Elongation (0.6 mm)	≥ 18%
Surface Treatment	Regular spangle / minimized spangle / zero spangle
Passivation	Chromate-free or chromate passivation

Key Applications of SGCC Zinc Coated Steel Coil

Building & Construction: Corrugated roofing sheets, wall cladding panels, structural purlins, and light steel framing systems
HVAC Ductwork: Air conditioning ducts, ventilation channels, and spiral pipe fabrication
Home Appliances: Washing machine housings, refrigerator back panels, and microwave oven enclosures
Automotive Components: Underbody shields, fuel tank brackets, and non-exposed structural parts
General Fabrication: Cable trays, electrical enclosures, storage racking, and agricultural equipment

Why Choose Our SGCC Galvanized Steel Coil

We operate through partnerships with tier-one Chinese mills equipped with continuous galvanizing lines running at speeds up to 180 m/min, ensuring uniform zinc coating thickness with deviation controlled within ±5 g/m². Every coil ships with an EN 10204 Type 3.1 mill test certificate covering chemical composition, mechanical properties, and zinc coating mass verified by X-ray fluorescence testing. Our annual export volume exceeds 50,000 MT of galvanized coil products, and we maintain ready stock in standard sizes for rapid dispatch from Tianjin and Shanghai ports.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for SGCC galvanized steel coil?

Our standard MOQ is 25 metric tons per specification. For mixed container orders combining multiple thicknesses or widths, we accept a combined minimum of 20 MT.

SGCC galvanized steel coil supplier

Do you provide material test certificates with each shipment?

Yes. Every shipment includes an original mill test certificate per EN 10204 Type 3.1, detailing chemical analysis, mechanical test results, and zinc coating weight measurements. Third-party inspection by SGS or Bureau Veritas is available upon request.

SGCC galvanized steel coil wholesale

What is the typical delivery time for SGCC coil orders?

Ready-stock items ship within 7–10 days after payment confirmation. Custom-produced orders with specific coating weights or non-standard widths typically require 20–30 days from order confirmation to port loading.

Can you supply SGCC galvanized coil with chromate-free passivation?

Absolutely. We offer RoHS-compliant chromate-free passivation as a standard option, meeting EU environmental directives. Anti-fingerprint coating and oiled surface treatments are also available for enhanced corrosion protection during transit and storage.

Acceptable SGCC Quality, Delivery Delay on Custom Width Resolved

Ordered 28 tons of SGCC coil, 0.8mm thickness, 750mm slit width, Z120 coating for wall cladding panel fabrication in Bogotá. Material quality itself was acceptable — chemical composition and mechanical properties per JIS G3302 were confirmed on the mill cert. The issue was delivery: quoted 20-25 days for the custom slit width but actual loading happened on day 33, causing a 10-day delay in our project schedule. After raising the concern, the supplier expedited the shipping arrangement and provided partial freight compensation. Communication during the delay could have been more proactive. Quality of the steel is good enough that we would consider reordering, but only after confirming production slot availability upfront before placing the next order.

Perfect SGCC Coil for Corrugated Roofing Sheet Line

We've been running a corrugated roofing sheet production line in Accra for 5 years and switched to this supplier 14 months ago. Latest order was 80 tons of SGCC, 0.3mm thickness, 1200mm width, Z100 coating — our fourth order in total. Zinc coating adhesion is excellent; our bend test at 180° shows zero peeling or flaking, critical for corrugating process. Coil weight averaged 5.2 MT per coil, consistent inner diameter of 508mm fitting our uncoiler without adjustment. Shipment from Shanghai arrived at Tema port in 19 days. The sales team proactively sent tracking updates at each shipping milestone. This level of reliability is exactly what we need to maintain our own delivery commitments to construction contractors.

Reliable SGCC Supply for Agricultural Equipment Components

Ordered a mixed container of 20 tons combining 0.6mm and 1.0mm SGCC coil, both Z80 coating, 1219mm width for agricultural machinery panels in Queensland. Appreciated the 20 MT mixed MOQ option — works well for our smaller production runs. Material met JIS G3302 requirements and elongation on the 0.6mm gauge was 21%, above the 18% minimum. Pricing was fair though not the absolute lowest we found — selected this supplier based on the Type 3.1 certificate and Bureau Veritas inspection availability. Transit time to Brisbane port was 22 days. Would rate 5 stars if payment terms were more flexible for repeat buyers.
