Tinned sheet specifications read like a code. “T3, 0.20 mm, 2.8/2.8 g/m², stone finish, palm oil, cut edge” means nothing if you do not decode each field. Consequently, buyers who write incomplete POs receive whatever the mill has in stock. Here are the six parameters to specify.

Parameter 1: Temper

Temper decides how hard the material is. Standard designations:

• T1–T2: soft, deep drawing.
• T3–T4: general can bodies.
• T5–DR8: work-hardened, stiff ends.

Consequently, specify T3 for bodies and DR8 for ends. Wrong temper and the can either wrinkles or cracks.

Parameter 2: Tin Coating Weight

The notation “2.8/2.8 g/m²” means 2.8 g/m² tin on each side. Heavier coating costs more but resists acids. Common weights:

• 1.1/1.1: light, decorative.
• 2.8/2.8: standard food cans.
• 5.6/2.8: acidic foods.
• 11.2/11.2: highly acidic or durable.

Parameter 3: Surface Finish

Two finishes:

• Stone finish (matte): standard, print-receptive.
• Bright finish: reflective, decorative.

Consequently, printed cans use stone finish. Decorative or closure stock uses bright.

Parameter 4: Thickness and Width

Thickness runs 0.15–0.50 mm. Width runs 500–1000 mm. Consequently, specify both. Furthermore, specify whether you want sheets or coil. Sheets cut to size; coil feeds your line.

Parameter 5: Edge Type

Two edge options:

• Mill edge: as-rolled, full width.
• Cut edge: slit to your exact width.

Consequently, cut edge suits can blanking. Mill edge suits general stamping.

Parameter 6: Oil Weight

Palm oil weight runs 8–12 mg/m². Too little and the surface rusts. Too much and printing ink fails to adhere. Consequently, specify the oil weight for your downstream process.

A Complete PO Reads

“T3 temper, 0.20 mm × 800 mm, 2.8/2.8 g/m² tin, stone finish, cut edge, 10 mg/m² palm oil, MTC per ASTM A624.”

Leave out any field and the mill substitutes its default.
