Nijhof blog – Fresh air
in this blog, we will follow the construction of the Nijhof farm and keep you informed on the details implemented to secure optimal welfare for the animals.The family Nijhof has an existing pig farm in Haaksbergen (The Netherlands)…
Nijhof blog – A breath of fresh air in the farm
The construction at the Nijhof farm is progressing fast. On top of that, the bad weather with snow and rain from last week has made way for sunshine and high temperatures.It could hardly be better…
Nijhof blog – The roof is done!
In the past few weeks since the last update, the Nijhof farm has gotten its roof, which means that the construction crew has begun with the interior. Because the floor is necessary for insulation the inside of the farm, the first step…

Collaboration is key!
All slats, crates and penning need to be properly fixed to beams and walls at all times such that the sow may not lift or pull slats out of the floor.
Floors should be assembled in a moderate climate, hence, not while freezing or in full sun. To prevent damage of the slats, assembly should be cancelled when temperature drops below 4 degrees Celsius. Slats may contain a maximum opening in between of 10mm. With larger openings the risk of injury of piglet or sow increases.
Placing hot or sharp items or throwing the latter on the floor may damage the product. During assembly of the floors, the slats should be placed without force. Forcing the slats into to floor may damage the floor directly or on long term. The usage of a rubber hammer instead or an iron hammer is recommended.
An expansion joint at every 7 meters of plastic slats is required.
The plastic slats exist of polypropylene. This material may shrink or expand due to temperature changes. The expansion rate of polypropylene (Dl) over a certain distance/length (l) with factor λ (0.00015) increases per degree Celcius: Dl = λ x l x Dt
This means that a floor of 7 to 10 meters long (depending on the type of slat) will grow with about 3 cm when temperature increases with 20 degrees Celsius. To compensate for this growth you will need to break the surface. This can be done by placing a piece of cast iron (with lay-on) between the slats, or an extra beam in the floor after every 7 meters.
The Pro Step, Pro Grip and Poly Pro slats have a special design with V-shaped bottom which is easily cleaned.
Only cleaning materials suited for polypropylene may be used. Cleaning of the floors with corrosive chemicals should be prevented at all times.
Yes! This slat is designed to fit perfectly on every other Vereijken flooring part such as the Poly Pro Concrete or Cast Iron 500×600 slats.
Unadvised. Intensively used locations such as the place under the trough need to be equipped with a cast iron or wear-resistant material. Usage of plastic flooring in these areas is always at own risk.
Are you looking for a plastic flooring suited for piglets and (free) sow? Choose for Pro Grip Heavy Duty!
Yes! The Pro Grip flooring is specifically designed to house loose sows and piglets in the farrowing period:
(maximum weight per slat = 500kg). The estimated strength of the floor, however, is only valid when used as intended and only when the floor has been correctly installed – see also:
