About RTS
Crafted by nature, perfected by precision, our slate delivers uncompromising strength and durability. Meticulously split from solid blocks, each piece boasts a smooth, fine grained surface with subtle longitudinal texture—naturally free from reactive minerals and fully compliant with BS EN 12326 (A1/S1/T1/W1 certified). Rigorous third-party testing confirms exceptional performance, even under extreme climatic stress.
Traceable Quality from Quarry to Roof Sourced exclusively from a single, trusted quarry and processed at our dedicated facility, every slate is palletized to the highest standards: shrink-wrapped, BS EN-certified, and traceability-coded for seamless logistics.
Nature’s Artistry, Built to Last
A testament to natural beauty, each slate features slight tonal variations in color and texture—most visible in sunlight. Over time, they develop a graceful patina, harmonizing with local weather conditions.
Pro Tips for Flawless Installation:
Quality Assurance: Cross-check shipments against our “Quick Quality Checklist” to guarantee premium-grade slate.
Aesthetic Balance: Blend slates from multiple pallets during installation to ensure uniform color distribution.
