- Roof systems
Hollowcore Cross-Section Explorer
Select a plank depth to see the cross-section and structural specifications.
The 8″ plank can span up to 36′ without intermediate support — enabling open floor plans that wood or cast-in-place concrete cannot achieve at this depth.
Design Assistance
Our engineering team works with your architects and structural engineers to optimize hollowcore plank selection for your specific project requirements.
Custom Manufacturing
Planks are manufactured to your exact specifications — custom lengths, notches, and openings cut to order in our Florida facility.
Delivery & Logistics
We coordinate flatbed delivery directly to your jobsite, with scheduling that keeps your construction timeline on track.
Professional Installation
Our experienced installation crews use certified rigging and crane equipment to set planks safely and precisely — floors, roofs, and stair systems.
Precast Stair Systems
Complete precast concrete stair systems manufactured and installed as a unit — safe, accessible, and ready for immediate use during construction.
Solid Concrete Planking
In addition to hollowcore, we produce solid concrete planking for applications requiring maximum load capacity in shorter spans.
The Structural Choice
That Outperforms the Rest
Hollowcore precast concrete is the preferred structural system for builders who demand speed, strength, and long-term value. Here's why smart contractors choose American Precast.
Faster Construction
Precast planks arrive ready to install. No formwork, no curing time. Your floor or roof deck is complete the same day it's set — dramatically shortening your construction schedule.
Superior Strength
Prestressed steel strands run through each plank, giving hollowcore concrete extraordinary tensile strength. Span up to 50 feet with no intermediate support columns.
Fire Resistance
Concrete is inherently non-combustible. Hollowcore planks meet or exceed fire resistance requirements for most building types — no additional fireproofing needed.
Sound Attenuation
The hollow cores and concrete mass provide excellent sound isolation between floors — far superior to wood-frame construction for multi-family and commercial buildings.
Cost Efficiency
The hollow cores reduce concrete volume by up to 30%, lowering material costs, reducing structural loads on foundations and walls, and cutting transportation costs.
Hurricane Resistance
In Florida's hurricane zone, concrete construction is king. Hollowcore systems provide the mass and rigidity to withstand extreme wind events that destroy lighter construction.
Hollowcore vs. Other Systems
| Feature | ★ Hollowcore | Wood Frame | Cast-in-Place |
|---|---|---|---|
| Construction Speed | Same-day installation | Weeks of framing + drying | Weeks of forming + curing |
| Fire Rating | 2+ hours inherent | Requires fireproofing | 2+ hours inherent |
| Sound Isolation | Excellent (50+ STC) | Poor (requires treatment) | Good (40+ STC) |
| Span Capability | Up to 50 feet clear | Limited to ~20 feet | Up to 30 feet |
| Hurricane Resistance | Excellent | Poor | Good |
| Long-Term Durability | 100+ years | 25–50 years | 75+ years |
