As a trusted stone supplier in Australia, Linnstone maintains strict quality standards to ensure consistent and reliable performance across all of our products. This document sets out Linnstone’s official Quality Control Standard for the Australian market, providing clear expectations for slab inspection and delivery.
It covers key quality checks such as colour variation, flatness, thickness tolerance, surface finish, and potential surface defects (including spots, voids, cracks, scratches, and more). A grading system (Grade A/B/C) is included to help fabricators, installers, and project teams assess slab quality accurately at each stage of the process.
This standard serves as an important reference throughout your collaboration with Linnstone, helping ensure each slab meets your project’s visual and functional expectations—from fabrication to final installation.
