Metal and Construction Guide

This guide explains how Northline lists materials and construction fields. It does not claim that any one material is universally best.

• Listed material means the verified material recorded for that SKU.
• Surface vs core may differ in layered construction; both require verification.
• Single-material vs layered construction is published only from manufacturing documentation.
• Interior and exterior finishes are separate fields and may differ.
• Base shape affects stability and burner contact; it is not inferred from photos.
• Handle attachment, lid material, and care documentation are product-specific.

Unsupported health claims are never published.
