What Do the Sheet Colours Really Mean?

STRUCTAflor particleboard flooring is a common building material on job sites, due to its structural performance, cost-efficiency and ease of installation. It has a simple, coloured-coded identification system designed to streamline selection and prevent installation errors.

This blog breaks down what each STRUCTAflor colour means in their general-purpose range, helping you choose the right board for the job every time.

What Is STRUCTAflor?

STRUCTAflor is a purpose-designed structural particleboard flooring system widely used across residential construction. Manufactured for strength and durability, it delivers reliable performance under Australian conditions and is engineered to meet loads outlined in AS/NZS 1170.1-2002.

Why Does STRUCTAflor Use Colour Codes?

STRUCTAflor particleboard flooring sheets feature colour-coded tongue edges in yellow, red and blue, to clearly distinguish the board type, thickness and intended application. These colours allow builders to identify the correct product at a glance, reducing handling errors and ensuring the right sheet is fitted in the right location.

The colour system also aligns with compliance requirements for particleboard flooring installation.
