Stone Columns (Industry Standard) | Traditional architecture, historical buildings | Material: Natural stone (e.g., granite, 2000 kg/m³) Durability: 50+ years (outlasts most synthetic materials) | Timeless aesthetic, fire-resistant (Class A) High load-bearing capacity | Heavy (2000 kg/m³ ▲1820 kg/m³ heavier than GFRC) High cost ($150+/unit) |
Pre-Cast Concrete Columns | Modern commercial spaces, cost-sensitive projects | Material: Reinforced concrete (2400 kg/m³) Durability: 30–50 years | Cost-effective ($80–120/unit) Weather-resistant | Heavy (▲2380 kg/m³ heavier than GFRC) Prone to cracking over time |
EPS Columns (Our Base) | Residential exteriors, temporary setups | Material: Expanded polystyrene (20 kg/m³) Durability: 10–15 years (ASTM D543 compliant) Finish: Roll coated (ASTM C695) | Lightweight (▲1980 kg/m³ lighter than stone) Easy installation ($40–60/unit) | Lower fire resistance (Class B) UV degradation risk (▲10+ years less than GFRC) |
GFRC Columns (Our Advanced) | High-end villas, commercial exteriors | Material: Glass fiber reinforced concrete (180 kg/m³) Durability: 25+ years (▲15 years over EPS) Fire resistance: Class A (▲1 level over EPS) | Lightweight (▲1820 kg/m³ lighter than stone) Customizable designs (ISO 3801 certified) | Moderate cost ($90–120/unit) Requires skilled handling (▲160 kg/m³ heavier than EPS) |
PVC Columns (Industry) | Indoor decor, temporary events | Material: Polyvinyl chloride (15 kg/m³) Durability: 10–12 years (ASTM D1784) | Ultra-lightweight (▲1985 kg/m³ lighter than stone) Corrosion-resistant | Poor UV resistance (▲8 years less than GFRC) Limited design flexibility |
Aluminum Columns (Industry) | Modern/industrial spaces, coastal areas | Material: Anodized aluminum (240 kg/m³) Durability: 20–30 years (ASTM B209) | Corrosion-resistant (saltwater environments) Sleek appearance | Poor fire resistance (Class C) Conducts heat/cold (▲220 kg/m³ heavier than EPS) |
