Production line and factory setup overview
Produces prestressed hollow-core concrete slabs through certified strand handling, long-line bed preparation, controlled concrete extrusion/slipforming, curing, detensioning, cutting, lifting, end treatment and structural release.
Recommended lowest-entry line configuration This is a strategic precast project requiring an experienced designer/EPC partner. Confirm code, certified prestressing strand, bed length, strand pattern, concrete technology, curing, heavy lifting, transport, quality laboratory and committed project off-take before feasibility approval.
Production process and implementation sequence
- Structural design/bed plan
- Strand receipt/tensioning
- Long-line bed preparation
- Concrete batching/extrusion
- Controlled curing
- Detensioning/cutting
- Lifting/end treatment
- Laboratory/structural release and transport
Products, capacity and market fit
- Approve a physical sample and applicable standard.
- Launch with a defined product range and documented tool settings.
- Keep material and quality records for each batch.
- Prestressed hollow-core concrete slabs - Slab depth/width, prestressing strand, concrete strength, void geometry, span/load, fire/acoustic performance, cut/opening rules, lifting/transport and structural certification - Large housing, schools, warehouses, commercial buildings, infrastructure and major developers
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Prestressing bed/tensioning system | Applies designed strand force | Certified strand/tension records |

| Curing/cutting system | Releases stable units | Strength/detension timing |
| Structural lab/handling system | Validates safe delivery | Load/camber/lift control |
Raw materials, utilities and factory requirements
- Certified prestressing strand, cement, graded aggregates, water, admixtures, release agents, repair/end-treatment materials, labels and transport fixtures
- Stable electricity, covered raw-material storage and protected finished-goods handling
- Guarded equipment, documented maintenance, essential spares and product-specific safety controls
Indicative low-entry investment and implementation plan
These planning ranges prioritize economical machinery, local labor and local civil works. Final pricing follows confirmed capacity, product specification, delivery terms and site conditions.
| Scope | Indicative range | Entry-plan note |
|---|---|---|
| Beds, strand tensioning and extrusion line | US$2.5m-8m | Strategic long-line production |
| Batching, curing, cutting and lifting | US$1.2m-4m | High-strength precast scope |
| EPC engineering, laboratory and commissioning | US$800k-3m | Design/test-led project |
| Indicative strategic total | US$4.5m-15m | Land, buildings, cranes and transport excluded |
