Concrete Slatted Floor for Pigs

The Farrowing Pen Combination Floor is a modular flooring system developed specifically for sow and piglet housing in commercial farrowing barns. It combines different flooring materials and functional zones within one pen so that the sow and newborn piglets can each receive flooring suited to their different requirements for grip, thermal comfort, drainage and durability.

A typical system combines polypropylene plastic slats in piglet and circulation areas with heavy-duty cast iron slats beneath or around the sow. Optional heating plates, solid resting sections, STEP-style elevated sow sections and manure-management accessories can be incorporated according to the farrowing system and farm management strategy.

The modular construction makes it possible to adapt the floor around traditional farrowing crates, variable-restraint pens and loose-farrowing systems. Panel dimensions, opening ratios, support profiles and floor zoning can be configured according to pen dimensions, manure-pit layout, sow size and project requirements.

• Multi-Material Floor Design: Plastic slats, cast iron slats, heating plates and solid sections can be combined within one farrowing pen.
• Separate Sow and Piglet Zones: Flooring can be selected according to the different thermal, traction and load requirements of the sow and piglets.
• Durable Plastic Slats: High-quality polypropylene flooring provides corrosion resistance and a livestock-friendly walking surface.
• Heavy-Duty Sow Area: Cast iron sections provide high load capacity and stable footing in areas exposed to concentrated sow loads.
• Efficient Manure Drainage: Slatted sections allow manure, urine and wash water to pass into the manure pit below.
• Slip-Resistant Surface: Structured flooring surfaces provide grip for animals during standing, lying and movement.
• Piglet Thermal Comfort: Optional heating plates create a warmer resting zone while the sow can remain on a cooler flooring area.
• Flexible Opening Ratios: Different slat designs can be selected to balance drainage, dryness and animal comfort.
• Modular Configuration: Multiple panel sizes allow floor layouts to be adapted around crates, feeders, piglet nests and pen partitions.
• Corrosion-Resistant Supports: Fiberglass, galvanized steel and other support systems are available for aggressive livestock-house environments.
• Easy Cleaning: Open slat patterns and smooth surfaces support efficient washing and disinfection between production batches.
• New-Build & Retrofit Compatibility: Suitable for new farrowing houses and replacement of existing pig flooring systems.

The combination-floor principle recognizes that the sow and newborn piglets require different floor conditions. The sow produces considerably more body heat and places a much higher mechanical load on the floor, while newborn piglets require a warmer microclimate and smaller, animal-friendly openings.

Cast iron or heavy-duty sow slats can therefore be positioned beneath the central sow area. Their high mechanical strength provides a stable surface, while thermal conductivity can help create a comparatively cooler lying area for the sow.

Polypropylene slats are used around piglet circulation and resting areas. Smaller or reduced-opening designs help provide secure footing while allowing manure and liquids to drain through the floor.

Heating plates can be incorporated into the piglet zone to provide a localized warm resting area without increasing the temperature of the entire farrowing room. This allows the floor layout to create separate thermal zones for the sow and litter.

All floor sections transfer animal and equipment loads through support profiles to structural bearing points around the manure pit. Correct support spacing and installation are determined according to the selected floor components and project design.

• Conventional sow farrowing crates
• Variable-restraint farrowing pens
• Loose-sow farrowing pens
• Commercial farrowing houses
• Piglet creep and resting areas
• Sow lying and standing zones
• Farrowing rooms with manure pits
• Large-scale sow breeding farms
• Nucleus and multiplier pig farms
• Prefabricated steel structure pig houses
• Existing farrowing-house renovation projects
• Turnkey commercial pig farm projects

The flooring layout can be engineered according to the farrowing-pen design, sow size, piglet area, manure-pit dimensions, heating requirements and structural support conditions.

• Overall floor length and width
• Plastic and cast iron floor ratio
• Sow-floor dimensions
• Piglet-floor dimensions
• Plastic slat opening ratio
• Cast iron slat opening ratio
• Closed or slatted floor sections
• Heating plate dimensions
• Electric heating system
• Hot-water heating system
• Elevated sow-floor configuration
• Fiberglass support profiles
• Galvanized steel support profiles
• Support beam spacing
• Cross-section adapters
• Floor fillers and spacers
• Manure openings and cleaning plugs
• New-build or retrofit installation

Installation Process:

1. Confirm farrowing-pen dimensions, sow position, piglet area, manure-pit layout and heating requirements.
2. Prepare supporting walls, brackets or beam bearing points according to the flooring drawings.
3. Install fiberglass, galvanized steel or other specified support profiles at the required spacing.
4. Position cast iron slats in the designated sow area according to the floor layout.
5. Install polypropylene slats around the sow and piglet zones.
6. Install heating plates and associated water or electrical connections where specified.
7. Install spacers, adapters, fillers, anchors and cleaning accessories.
8. Mount farrowing crate or pen components using the specified floor anchoring arrangement.
9. Check all panels for correct alignment, full bearing and secure fastening.
10. Complete a final load, drainage and safety inspection before animals enter the pen.

Maintenance Recommendations:

• Wash and disinfect floor surfaces between farrowing batches according to the farm biosecurity program.
• Keep slat openings clear of hardened manure, excess feed and other debris.
• Inspect plastic panels for cracking, excessive wear or deformation.
• Inspect cast iron sections for damage and ensure they remain securely seated.
• Check support profiles, brackets and fastening systems periodically.
• Inspect heating plates and heating connections according to the manufacturer's maintenance requirements.
• Replace damaged floor elements before continued livestock use.
• Do not exceed the specified floor loading or support span for the selected components.

Q1: What is a farrowing pen combination floor?
It is a modular floor that combines different materials such as polypropylene slats, cast iron slats and heating plates within one farrowing pen to meet the different requirements of the sow and piglets.

Q2: Why combine plastic and cast iron flooring?
Plastic flooring provides a corrosion-resistant and animal-friendly surface for piglet and circulation areas, while cast iron provides high load capacity and a suitable surface for the heavier sow.

Q3: Can a heating plate be integrated into the floor?
Yes. Electric or hot-water heating plates can be installed in the piglet resting area according to project requirements.

Q4: What material is used for the plastic slats?
High-quality polypropylene is commonly used for farrowing-floor plastic slats because of its durability, corrosion resistance and suitability for livestock environments.

Q5: What material is used for the cast iron sections?
Ductile cast iron is commonly used. GGG40 is a proven material used in comparable commercial farrowing-floor systems.

Q6: Can the flooring layout be customized?
Yes. Floor dimensions, material combinations, slat sizes, opening ratios, heating areas and support arrangements can be configured according to project requirements.

Q7: Is this floor suitable for loose-farrowing pens?
Yes. Combination flooring can be designed for conventional farrowing crates, variable-restraint systems and loose-sow farrowing pens.

Q8: Can it be installed over a manure pit?
Yes. The system is normally supported above a manure pit or slurry channel so that manure, urine and wash water can drain below the livestock area.

Q9: Can the floor be used in an existing pig house?
Yes. Retrofit projects can be designed after checking the existing manure pit, bearing surfaces, floor dimensions, farrowing equipment and structural conditions.

Q10: What information is required for a quotation?
Please provide the project country, number of farrowing pens, pen dimensions, floor layout, manure-pit dimensions, preferred farrowing crate or pen type, heating requirements and available building drawings.
