Geographic Concentration of Aluminum Prefab Factories
1. Metro Manila Industrial Belt
- Valenzuela City: 60% of metro-region prefab manufacturers
- Strategic access to North Harbor (aluminum imports from China/Japan)
- Proximity to NLEX/SLEX highways for nationwide distribution
2. CALABARZON Manufacturing Corridor
- Carmona, Cavite: Emerging hub with 15+ prefab plants
- Advantages:
- 30-minute reach to Batangas International Port
- Lower land costs vs Metro Manila (₱2,800/sqm vs ₱18,000/sqm)
3. Central Visayas Disaster Response Cluster
- Mandaue City, Cebu: 12 specialized shelter factories
- Supplies typhoon-prone areas (Leyte/Samar)
- Integrated with local shipbuilding supply chains
4. Mindanao Development Zones
- Davao City: 8 factories serving Bangsamoro reconstruction projects
- Cagayan de Oro: Gateway to Lanao disaster corridors
