The Barn Is A Production Line. Fit It Like One.
A pig or cattle barn is four systems running against the clock: housing that protects the animal, flooring that stays clean under it, feeding that hits target weight, and air and manure handling that keep the vet and the environmental officer away. This page gathers the 24 equipment lines NPW builds for that job — from farrowing crates and sow stalls to 32-ton feed silos, slatted floors, cooling pads and DAF effluent plants — grouped by the zone of the barn they belong to, with the figures that matter printed on each card.
Housing, Feed, Air And Manure Are One System
Bought separately, barn equipment argues with itself: a floor whose slots fight the scraper, troughs the auger line cannot reach, fans sized for a barn whose inlets the pads then strangle. The five zones below are engineered as one set — and every number on this page comes from our own product datasheets, not from a brochure.
- Sized by head count, not by catalogue
Sow stalls from 600 to 1,100 mm wide, farrowing crate sections at 3,600 and 3,800 mm, headlocks in 8- and 12-head frames — the pen is set out around the animal and your barn column grid, and the steel follows the layout, not the other way round.
- The slot width is chosen by the hoof
9 mm triangular steel under sows, 11 mm BMC in the creep and nursery, 20–23 mm for fattening pens, up to 30 mm for cattle. Slot width decides what passes through and what turns into injury and culling, so each floor line carries its own range.
- Manure is a product line, not a disposal bill
V-scrapers move it out of the house, solid-liquid separators dry it below 60% moisture into stackable fertilizer, a windrow turner finishes the bedding, and a DAF plant polishes the water to ≥90% suspended-solids removal before the discharge permit gets involved.
Six Failures We Build Against
Each failure below costs a farm more per year than the equipment that prevents it. Under every failure sits the NPW line that closes it.
Piglet losses concentrate in the first days
Newborn piglets need 30–38 °C while the sow needs 20. Without a heated creep zone they lie against the sow for warmth, and crushing becomes the main cause of pre-weaning mortality. Anti-crush bars, sow location bars and carbon-fiber creep pads at 120–240 W exist to move that decision.
A sow that is too hot stops eating
Above the thermoneutral zone, feed intake and milk yield drop, and the loss lands on the litter. Negative-pressure fans moving 26,000–60,000 m³/h combined with evaporative pads that drop intake air by 5–12 °C is the standard fix — sized per house, not per farm.
Respiratory damage is cumulative and invisible
Ammonia rising from underslab pits and slurry channels burns airways at concentrations the nose adapts to within minutes. A biological scrubber removing at least 85% of ammonia, ahead of fans that actually move the air, protects weight gain and the people working in the house.
Every kilo spilled is bought twice
Open troughs, ragged auger lines and unsealed silos turn feed into fly and rodent feed. Sealed 3–32 t silos with ground-operated roofs, stainless troughs with adjustable flow dividers, and mixing homogeneity of CV ≤5–8% keep the ration budget where it belongs.
Discharge rules became permit conditions
Raw slurry to the ditch is now a fine in most jurisdictions. Scrapers that separate solids at source, screw presses drying the cake below 60% moisture, and DAF clarification at 90–95% suspended-solids removal turn effluent into fertilizer plus a clean discharge.
A failed floor injures the animal above it
Rusted support beams, cracked concrete and razor slot edges end in lameness, shoulder sores and culls. Pultruded FRP beams that cannot rust, C40 double-rebar concrete and cast BMC around internal rebar grids are specified for 20-year service, not one batch of pigs.
Housing & Containment
Crates, stalls, pens and headlocks in hot-dip galvanized steel — the frames the animal lives against for its whole stay. Sections are sized to the species and the phase: farrowing crates with anti-crush bars and creep space, gestation stalls with anti-jump rear gates, weaning pens with non-conductive plastic slats, fattening fronts rated against rooting and impact, and cattle headlocks in self-locking 8- and 12-head frames. Send the barn length and head capacity and we return the pen layout with the steel list.

Five frame lines covering farrowing to fattening, plus the cattle side
Slatted Floor System
The floor is the hardest-working surface in the barn: it has to carry the animal, pass the dung, survive urine and disinfectant, and stay kind underfoot. We build four floor materials — cast BMC composite, C40 machine-made concrete, virgin PP and nylon, and triangular steel — plus the FRP beams they sit on and the PP molds for pouring concrete on site. The table underneath compares them on the numbers that decide the choice.

Floor Systems Compared
Figures from the datasheet of each series — slot width is the first number to match to the animal
| Floor System | Best For | Panel Size | Slot Width | Load | Service Note |
|---|---|---|---|---|---|
| BMC composite NPW-CSF | Nursery, fattening, sow half-slat, piglet creep | 1,100–3,000 × 450–700 mm, 35–80 mm | 11–23 mm by zone | Internal rebar grid, main bar 10 mm | Flame-retardant; 20+ year indoor life |
| Machine-made concrete NPW-CSL | Fattening houses and heavy cattle | 1,300–3,000 × 600 mm, 70–120 mm | 16–30 mm self-cleaning | C40, double-layer rebar, over 1,000 kg | Emery non-slip; cast-in inspection hatch option |
| PP & nylon NPW-PSF | Piglets, sows and sheep on plastic | 500–700 mm panels, 1.7–4.2 kg each | 5–50% opening by model | >250 kg per panel, >500 kg/m²; nylon >450 kg | Warm underfoot, chemical-proof, non-stick |
| Triangular steel NPW-TSF-2407 | Sow farrowing bays | 2,400 × 700 mm, 10 mm bar section | 9.0 mm ± 1.0 mm | 800 kg central load, zero deflection | Flip-up rear cleanout hatch; hot-dip after weld |
Feeding & Watering
Feed is stored, milled, mixed and presented — and every step leaks money when it runs through open equipment. Galvanized corrugated silos from 3 to 32 tons keep the ration dry and load from the ground; 9HT grinder-mixer units batch from 500 to 3,000 kg with homogeneity of CV ≤5–8%; and SUS 304/201 troughs with adjustable flow dividers present mash or pellets to nursery, fattening and gestation pens without the corners that trap stale feed.
Storage, Processing & Troughs
From the silo roof to the trough edge
Barn Climate
Ventilation, cooling, heating and odor are one air circuit: the fans set the negative pressure, the pads drop the intake temperature, the fabric ducts spread air without drafting the animals, the creep pads hold the piglet zone at 30–38 °C, and a biological scrubber cleans what leaves the house. Sizing any one of them without the other four is how barns end up windy, wet or both.
Fans, Pads, Ducts, Heat & Deodorizing
The whole air circuit, from inlet to stack
Manure & Effluent
Manure handling decides whether the farm smells like a business or a complaint. Under-slat V-scrapers remove solids at source on a PLC timer, screw presses and slanted screens dry the cake below 60% moisture into stackable fertilizer, DAF plants take the water to 90–95% suspended-solids removal, multi-disk presses dewater the sludge, and a compost turner finishes deep bedding into saleable organic fertilizer.

Solids, liquids, sludge and smell — each with its own machine
What A Fitted Barn Looks Like
Three frames reserved for installations of this equipment — photographs, not renders. Each 1:1 slot drops in as our works and reference farms are photographed; the captions state what each frame will show.
What The Steel, Floor And Electrics Are Made Of
Hot-dip galvanized after fabrication
Crates, stalls, silo bodies and fan frames are galvanized, and the triangular sow floor is hot-dip galvanized after welding so the welds are protected too. Fan housings carry 275 g/m² galvanized sheet as standard.
SUS 304 wherever slurry or feed touches
Troughs in 0.8–1.2 mm stainless, separator screens and press discs in solid SUS 304 with alloy edges, wedge-wire grids where the dewatering result decides the moisture.
Reinforcement inside the floor, not around it
BMC slats are cast around a steel rebar grid with a 10 mm main bar, C40 concrete carries double-layer high-tensile rebar, and FRP beams are pultruded past 420 MPa — the load path is in the section itself.
Electrics rated for wet barns
IP68-sealed heating pads survive steam and water-spray wash-down, fans run 380 V three-phase with direct drive or auto-tensioning belts, and scraper and cooling circuits run PLC cabinets with 24-hour timers.
Sized from your barn drawing
Pen layout, beam span, channel depth, silo leg height and fan count are worked from your dimensions and head numbers — a 32 t silo stands 8.3 m on eight legs, and the slab under it has to be yours.
One container, one supplier
Crates, floors, silos, fans, separators and the DAF unit ship on the same booking, with the installation sequence and the wear list written for the whole barn rather than per machine.

FAQ
Match the slot to the hoof and the dung: 9.0 ± 1.0 mm triangular steel under sow farrowing bays, 11 mm BMC or plastic in the creep and piglet zones, 16 mm in the nursery, 20–23 mm for fattening pens, and 23–30 mm self-cleaning slots for heavy cattle. If you tell us the phases you run, we will mark a floor material and a slot width per house instead of selling you one floor for everything.
Inside houses we default to BMC composite: cast around a rebar grid, flame-retardant, quiet underfoot and rated for over 20 years of indoor service. Concrete wins where budget and heavy load dominate — C40, double-layer rebar, over 1,000 kg — especially for cattle and outdoor runs. PP and nylon suit piglets and sheep: panels weigh 1.7–4.2 kg, install by hand, stay warm and shrug off disinfectant. The triangular steel TSF-2407 is the specialist for farrowing bays, with a flip-up rear hatch that clears the manure channel without lifting panels.
Work from daily consumption and the delivery interval you can hold: the silo line runs 3, 5, 10, 15, 20 and 32 tons (4.93–50.2 m³, overall heights 3.9–8.3 m), so a house eating one ton a day with weekly delivery wants at least the 10 t model. The 9HT grinder-mixer units batch 500, 1,000, 2,000 and 3,000 kg with homogeneity of CV ≤8% on the vertical models and ≤5% on the horizontal ribbon mixers. Send the daily tonnage and we will state the model and the leg loading.
The fans exhaust air to set a negative pressure, so air can only enter through the pad wall, where evaporation does the cooling. Fan models move 25,000–60,000 m³/h (900–1,400 mm blades, 0.55–1.5 kW, 380 V three-phase), and the 100 or 150 mm cellulose pads drop intake air by 5–12 °C depending on humidity. The two are sized together: too few pads and the fans starve, too many fans and the air short-circuits past the animals.
Yes — the heating wire is cast inside a high-strength BMC shell with an IP68-sealed enclosure, rated for steam and water-spray cleaning. The single 1,100 × 600 mm pad runs 120 W and the double 2,200 × 600 mm pad 240 W with dual-zone control, both thermostatic at 30–38 °C. The insulated creep boxes take the same wash-down and carry an inspection hatch plus a pre-drilled infrared lamp port.
Below 60% moisture — dry enough to stack, haul and compost rather than pump. The screw presses handle 10 and 25 m³/h and the slanted screens 20–50 m³/h, all with SUS 304 screens and non-clogging cutter pumps. What you do next decides the machine: saleable fertilizer favors the press, a lagoon favors the screen, and many farms run a screen for volume with a press behind it for the cake.
Dissolved air flotation lifts suspended solids, fats and oils, and a meaningful share of COD and BOD out of the water — suspended-solids removal is rated at 90–95% across the range. Five models cover 8 to 300 m³/h, from a 3.7 × 2.1 m skid to a 19.1 × 3.4 m installation, with main pump power from 3.0 to 37.0 kW. For a discharge permit, tell us the local limits and we will state what the unit achieves upstream of any polishing stage.
That is the default way we quote it. Crates, floor panels, troughs, fans and the separator ride together with long items braced and electrics boxed; the constraint is usually the silo, whose support legs run 2.85–5.2 m and whose cone diameter reaches 3.7 m on the 32 t model. We state what fits the booking before you commit, and every pallet is photographed before the doors close.
Yes — from your internal dimensions and head capacity we return a pen layout that sets the crate rows, walkways, trough lines and channel positions, and the equipment list follows from that drawing rather than from a price list. For projects that continue through the slaughter side, the same layout is handed to the line engineers; see the Poultry & Livestock Full Chain Solution for how the two halves connect.
