Concept / Description

Profile Concrete Tiles are architecturally engineered roofing elements that combine the structural benefits of reinforced concrete with innovative design features. Their distinctive profile—achieved through precise moulding or extrusion—serves multiple functions. It promotes superior interlocking between tiles, increases resistance to wind uplift, and improves water dispersion by creating overlapping joints that deter water ingress.

Material Composition

These tiles are typically produced from a mix consisting of Portland cement, natural aggregates, and additives that enhance workability and durability. The additives may include chemical accelerators, fibre reinforcements, and water-repellent admixtures which serve to optimise the physical attributes of the tiles. The careful control of the water-to-cement ratio during mixing is essential to achieve a balance between strength and durability.

Manufacturing Processes

There are primarily two manufacturing approaches used to produce Profile Concrete Tiles:

• Extrusion Process: In this method, the concrete mix is forced through a die, creating a continuous profile that is then cut into individual tiles. Extrusion allows for high precision and uniformity in the tile profiles.
• Moulding Process: Alternatively, the concrete mix is cast into moulds where it is allowed to cure. Moulding can yield tiles with specific textures or patterns that are difficult to achieve through extrusion.

Both methods have distinct advantages, with extrusion frequently preferred for its consistency and low variability, while moulding is often chosen for bespoke or high-design architectural applications.
