Material Composition | Heavy-duty outdoor use, urban landscaping | Industry Standard: Plastic (HDPE, 2mm thickness) Our Base: Cast Iron (ASTM A48 Grade 20, 3mm thickness) ▲ Our Advanced: Cast Iron + Eco-Coating (ASTM A48 Grade 25, 4mm + 0.5mm coating) ▲ | High load-bearing capacity (Our Base/Advanced) Corrosion resistance (ASTM A48) | Cast iron is heavier (e.g., 15kg vs. 5kg plastic) ▲ Higher upfront cost for Advanced coating |
Drainage System | Preventing root rot in potted plants | Industry Standard: Basic drainage holes (2 holes, 15mm diameter) Our Base: Enhanced drainage (4 holes, 20mm diameter) ▲ Our Advanced: Overflow channels + 6 drainage holes (25mm diameter) ▲ | Reduces waterlogging risk (▲20mm diameter ▲) Prevents overflow in heavy rain | Complex design may increase manufacturing cost |
Durability | Long-term outdoor exposure in coastal areas | Industry Standard: 3 years (ASTM G85 salt spray test) Our Base: 5 years ▲ (ASTM G85, 500 hours) Our Advanced: 7 years ▲ (ASTM G85, 1000 hours + UV-resistant coating) | Extended lifespan (▲2 years over Base) ▲ Withstands saltwater corrosion | Advanced coating requires annual maintenance |
Aesthetic Design | Modern garden decor, historical projects | Industry Standard: Plain, neutral-colored plastic Our Base: Painted finish (RAL color options) ▲ Our Advanced: Antique finish + intricate patterns ▲ (ASTM D523 gloss <10%) | Customizable to match styles (▲RAL colors ▲) Antique finish mimics aged patina | Specialty finishes may fade faster in direct sunlight |
Environmental Impact | Eco-conscious landscaping projects | Industry Standard: Non-biodegradable plastic Our Base: Recycled cast iron (30% post-consumer material) ▲ Our Advanced: 100% recyclable + biodegradable coating ▲ | Reduced landfill waste (▲30% recycled content ▲) Biodegradable coating breaks down in 2 years | Biodegradable coating requires compost conditions for full decomposition |
Weight/Portability | Frequent relocation of planters | Industry Standard: 5kg (plastic) Our Base: 15kg (cast iron) ▲ Our Advanced: 12kg (hollow core design) ▲ (20% lighter than Base) | Advanced version balances weight (▲12kg ▲) Sturdy for heavy plants | Cast iron requires stable placement due to weight |
