Why Precision Slit Galvanized Steel Strip Matters
Review certificate records, scope and current status. Confirm order-specific documentation and inspection requirements with the export team.
Common Applications of Slit Galvanized Steel
Industries rely on slit galvanized strip for cable trays, electrical enclosures, roll-formed profiles, and metal framing. The material offers excellent formability and corrosion resistance, especially when specified with Z120 or Z275 coatings. A galvanized steel supplier with in-house slitting capabilities can produce custom widths exactly to your drawings, reducing waste and secondary operations. For example, solar tracker manufacturers demand slit strips with tight width tolerances of ±0.2 mm for their rail systems. Our factory in Boxing, Binzhou has invested in modern slitting heads and edge conditioning to meet these requirements consistently.
Key Specifications: Zinc Coating and Grade Options
When sourcing from any slit galvanized steel strip supplier, you must verify the zinc coating designation. Common options include Z60 (60 g/m² total both sides), Z120 (120 g/m²), and Z275 (275 g/m²). The coating weight directly impacts service life in corrosive environments. Below is a comparison table showing typical properties for our hot dip galvanized coil products:
| Zinc Coating | Coating Weight (g/m²) | Typical Thickness Range (mm) | Common Applications | Corrosion Resistance |
|---|---|---|---|---|
| Z60 | 60 | 0.3 – 1.5 | Indoor ducting, light profiles | Standard |
| Z120 | 120 | 0.4 – 2.0 | HVAC, cable trays, automotive parts | Good |
| Z275 | 275 | 0.5 – 3.0 | Solar structures, agricultural, outdoor | Excellent |
All our slit coils are produced from prime hot dip galvanized coil with full mill certification. The zinc coating Z60 Z120 Z275 options allow buyers to select the right cost-performance balance. For export orders, we provide FOB pricing from Tianjin Xingang port with lead times of 15–25 days after deposit.

Why Choose a Factory Direct Supplier
Many buyers compare prices between service centers and mills. A galvanized steel supplier like ChinaCNU Steel that controls the entire production chain—from hot dip galvanizing to precision slitting—can offer better pricing and traceability. Service centers often source coils from multiple mills, leading to inconsistent mechanical properties. In contrast, our factory in Boxing, Binzhou produces all material from controlled heats, ensuring that each slit coil has the same chemistry and coating adhesion. For large projects with MOQ 25 tons, this consistency reduces production line adjustments and scrap rates.
Export Capabilities and Logistics
With over 15 years in the export business, we have shipped slit galvanized steel strip to 80+ countries across Southeast Asia, the Middle East, Africa, Europe, and South America. Our logistics team consolidates containers at Tianjin Xingang port, offering both FOB and CIF terms. The standard MOQ of 25 tons per specification allows buyers to mix widths and coatings within the same container. For example, you can order 10 tons of Z120 strip at 50 mm width and 15 tons of Z275 strip at 100 mm width on one purchase order. This flexibility makes us a preferred slit galvanized steel strip supplier for distributors and OEMs alike.
Frequently Asked Questions
What is the minimum order quantity for slit galvanized steel strip?
Our standard MOQ is 25 tons per specification. However, for trial orders or new customers, we may accept 20 tons after reviewing the specific requirements. Contact our sales team with your exact width and coating needs.
How do you ensure the zinc coating does not peel during slitting?
We use carbide slitting knives with precise clearance settings and lubricated edges to prevent coating damage. Each coil is tested for coating adhesion using a bend test per ASTM standards. Our process ensures the zinc layer remains intact even at the cut edge.
Can you supply slit strips with Z275 coating for outdoor solar structures?
Yes, Z275 is one of our standard coatings. We regularly supply hot dip galvanized coil with Z275 for solar mounting systems. The thicker coating provides excellent corrosion resistance in coastal and industrial environments. Please specify the required width and thickness for a quotation.
What payment terms do you offer for international buyers?
We typically accept T/T (30% deposit, 70% balance before shipment) or L/C at sight. For long-term partnerships, we can discuss more flexible terms. All pricing is quoted FOB Tianjin or CIF to your destination port.
How do you handle edge burrs on slit coils?
Our slitting lines include edge conditioning stations that remove burrs and micro-cracks. We guarantee a maximum burr height of 0.05 mm on standard orders. For critical applications like electrical components, we can achieve even tighter tolerances upon request.
