Summary of Technical Specifications for Metal Porphyry Paving Stones

1. Product Types and Dimensions

The document lists various sizes and types of metal porphyry paving stones, categorized primarily by dimensions (length x width x thickness in cm) and surface finish or application type.

Standard Porphyry Stones: Sizes range from 20x10x5 cm up to 120x80x12 cm, with thicknesses varying between 5 cm and 12 cm.
VS4 Grade Stones: Specific sizes include 60x20x12 cm and 80x60x12 cm, indicating a particular quality or specification level.
Surface Finishes: Includes black, metal, porphyry, white finishes.

2. Coverage and Unit Density

Each stone size is associated with a unit density per square meter (u/m2), indicating how many units are required to cover one square meter. Examples include:

40x40x5/7/8 cm: 6.25 units/m2
20x20x5/8 cm: 25 units/m2
30x10x6/8/10 cm: 33.33 units/m2
120x80x12 cm: 1.04 units/m2

3. Traffic Load Classifications

The stones are categorized based on their suitability for different vehicular traffic loads:

Medium Vehicular Traffic: Suitable sizes include 20x10x8 cm, 20x20x8 cm, 30x10x10 cm, 30x20x10 cm.
Heavy Vehicular Traffic: Includes stones sized 20x10x12 cm.
Light Vehicular Traffic: Includes sizes such as 30x20x8 cm, 40x20x8 cm, 40x40x8 cm, 60x40x8/10 cm, 60x20x12 cm, 80x60x12 cm, and 120x80x12 cm.

4. Special Applications

Floating Installation: Stones sized 50x50x5.5 cm and 60x40x7 cm are designated for floating installations.
Stone Cladding (Aplacado): Sizes include 20x20x5 cm, 40x20x5 cm, 40x40x5 cm, and 60x40x5 cm, indicating use as stone cladding rather than paving.

5. Key Parameters and Recommendations

Thickness varies to accommodate different traffic loads and installation types.
Unit density per square meter is critical for estimating material quantities.
Selection of stone size and thickness should align with expected traffic load to ensure durability.
VS4 designation likely refers to a quality or strength standard suitable for heavier loads.

This summary provides a structured overview of the stone types, dimensions, coverage, and recommended applications based on traffic load and installation method.
