Core Layer: Load Capacity ≥ 5000 kg/m², Thickness 20-100 mm

Component Specifications

Definition

The core layer in industrial flooring systems is a critical structural component typically installed between the subfloor and surface layer. It serves as the primary load-distributing element, designed to withstand dynamic and static loads from machinery, vehicles, and operational activities. This layer ensures dimensional stability, prevents cracking, and provides a uniform base for surface materials in demanding industrial environments.

Working Principle

The core layer operates on the principle of load distribution and stress dissipation. It transfers concentrated loads from surface activities across a wider area to the subfloor, preventing localized stress points that could cause structural failure. By maintaining consistent thickness and density, it creates a stable platform that minimizes deflection and vibration transmission.
