Technical Specifications of Stone Finish Tinplate Coil

Stone Finish Tinplate Coil - Premium Cold Rolled Steel for Packaging & Manufacturing

Stone finish tinplate coil represents a specialized cold-rolled steel product with a distinctive matte surface texture, engineered specifically for applications demanding superior paint adhesion and decorative finishes. This premium-grade material finds extensive application in metal packaging, decorative containers, and industrial components where conventional bright finishes prove unsuitable. Manufactured through controlled cold rolling processes that create a finely textured surface, stone finish tinplate serves critical roles in the food and beverage packaging industry, aerosol can production, and specialty metal fabrication sectors requiring optimal coating performance.

What is Stone Finish Tinplate Coil?

Stone finish tinplate coil is a low-carbon cold-rolled steel substrate coated with a thin layer of tin, characterized by a uniformly matte surface texture created through specialized rolling techniques. Unlike bright finish tinplate with its mirror-like appearance, the stone finish exhibits a controlled surface roughness typically measuring Ra 0.4-0.8 μm, providing enhanced mechanical keying for subsequent coating systems while maintaining the corrosion-resistant properties inherent to tin-plated steel.

Stone Finish Tinplate Coil Technical Specifications

Our stone finish tinplate coil complies with EN 10202:2001 standards for electrolytic tinplate, featuring base steel thickness ranging from 0.15mm to 0.49mm with tin coating mass options between E2.8/2.8 (2.8g/m² per side) and E11.2/11.2 (11.2g/m² per side). The material demonstrates tensile strength of 290-450 MPa depending on temper grade (T-2 through T-5), with surface roughness deliberately controlled between 0.4-0.8 μm Ra to optimize paint adhesion performance. Standard coil widths span 600-1050mm with coil weights reaching 10-12 metric tons per unit.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard minimum order quantity for stone finish tinplate coil is 25 metric tons per specification, though we accommodate smaller trial orders of 10 tons for qualified customers establishing new product lines or conducting coating system validation testing.

Do you provide material test certificates?

Yes, every shipment includes comprehensive Mill Test Certificates (MTC 3.1 per EN 10204) documenting chemical composition analysis, mechanical property test results, tin coating weight measurements, and surface roughness verification data traceable to the specific production heat and coil identification numbers.

What is the typical delivery time?

Standard lead time for stone finish tinplate coil orders ranges from 35-45 days ex-works following purchase order confirmation, encompassing production scheduling, quality inspection protocols, and export documentation preparation. Expedited production slots may be available for urgent requirements subject to mill capacity and surcharge application.

Can you cut to custom sizes?

We provide precision slitting services to customer-specified widths with tolerance of ±0.5mm, along with cut-to-length processing for sheet applications. Our slitting lines accommodate widths from 100mm to 1050mm, while shearing capabilities handle lengths up to 2000mm with edge quality suitable for direct stamping operations without secondary deburring requirements.
