For example, 60x120 cm tiles come in boxes of 2 pieces covering 1.44 m², weighing approximately 32.4 kg per box, with 30 boxes per pallet.

Physical and Chemical Properties

The tiles conform to international standards (ISO 10545 series) for physical and chemical properties, ensuring quality and durability:

• Dimensions: Length and width tolerance ±0.5% or ±2 mm; thickness tolerance ±5% or ±0.6 mm.
• Linearity and Orthogonality: Edge straightness ±0.5% or ±2 mm; wedging ±0.5% or ±2 mm.
• Planarity (Warpage): Maximum ±0.3% or ±1.5 mm.
• Water Absorption: ≤ 0.1%, classified as Bla GL E group, indicating very low porosity.
• Breaking Strength: Minimum 1300 N; modulus of rupture ≥ 35 N/mm².
• Frost Resistance: Tiles show no alteration after frost exposure.
• Thermal Shock Resistance: Tiles are resistant to temperature variations.
• Surface Abrasion Resistance: Classified as Class 3-4, suitable for moderate to heavy foot traffic.
• Chemical Resistance: Resistant to chemical attacks except hydrofluoric acid.
• Stain Resistance: Minimum Class 3, ensuring good resistance to staining.
• Slip Resistance: Coefficient of friction meets DIN 51130 R10 standard for non-leveled tiles; wet and dry friction coefficients ≥ 0.40, ensuring safety against slipping.
• Color Variation: Classified as V2, indicating slight variation in shading between tiles.

Additional Information

The tiles have a surface hardness rating greater than 6 on the EN 101 scale, indicating high scratch resistance. Thermal expansion coefficients are measured between 50°C and 400°C, with test methods available. Special pieces such as battiscopa (baseboards) and mosaics are also part of the collection.
