Pvc whelping box with playpen

Deqing Huazhijie Railing & Fencing Co., Ltd. has produced extruded PVC products since 2003 from Huzhou, near Shanghai, and supplies fence systems and pet enclosures to breeders, kennels, pet distributors and importers. The custom PVC whelping box with playpen suppliers range is built around one requirement: a rigid, waterproof whelping enclosure that assembles in minutes, disinfects between litters and stays serviceable for years.

A Whelping Box and Playpen in One PVC Structure

The unit is a modular PVC enclosure: a low-walled whelping area for the dam and newborn pups that extends into a taller playpen zone as the litter grows. Panels, posts and rails use the same extruded profiles as our fence lines, so the frame stays square under load and does not absorb urine, milk or cleaning agents the way plywood or MDF boxes do.

• Material: 100% virgin PVC, lead-free formulation, white finish.
• Behaviour in service: waterproof, rot-resistant, no swelling at cut edges, no splintering.
• Cleaning: wipe-down or hose-down; mild detergent and water handle routine sanitation.
• Reuse: panels come apart and stack flat for storage between litters.

Standard Sizes and What Each One Fits

Three standard footprints cover most breeding programmes, all at 18.9" wall height. Height is the variable breeders change most often, so we treat 18.9" as the base and build other heights on request.

Footprint figures are calculated from the outer dimensions. For a dam with a large litter, the playpen extension usually decides the size rather than the whelping area itself.

Component Specifications

Rails are routed before packing, so pickets drop into position without field drilling. Posts arrive with flat caps and feet, which protect flooring and stop the frame from walking on smooth surfaces.

The Pig Rail, Pickets and Airflow

The 7/8" x 6" perimeter rail is pre-routed with a round pig rail, a raised inner ledge that gives newborn pups a space along the wall where the dam cannot lie on top of them. It is the most important safety detail in a whelping enclosure, and it is formed into the rail rather than added as a loose part.

• Pig rail: rounded profile, no sharp edges at pup height.
• Pickets: 0.5" x 1.6" x 17.8" verticals, spaced for airflow and visual contact while keeping pups contained.
• Post caps: flat caps close the post tops, leaving no open sockets at paw or head height.
• Post feet: lift the frame slightly off the floor and spread load at each corner.

Airflow matters more than most buyers expect. A closed box traps humidity and ammonia; the picket spacing keeps air moving while the 18.9" wall still blocks draughts at floor level.

Assembly, Placement and Cleaning

Assembly is tool-light: posts, rails and pickets are cut and routed to length, and the frame goes together in a fixed sequence. Two people can complete a standard unit in a few minutes, and the same sequence reverses for flat storage.

1. Lay out the posts on a level surface and fit the post feet.
2. Insert the pre-routed rails into the post openings and check the frame for square.
3. Drop the pickets into the rail routing, working from one end.
4. Fit the flat caps and confirm every joint is fully seated.

Indoors, the box sits on a washable mat or vinyl sheet; outdoors, place it on a hard, level surface rather than soil so the frame stays square and the floor stays hygienic. Between litters, a mild detergent solution followed by a rinse is enough. PVC needs no sealing, staining or repainting.

Configuration Options and Custom Work

We build the three standard sizes as catalogue items and configure the rest to the breeding programme. Because the profiles are extruded in our own plant, changes to height, width, rail position and connection type do not require new tooling.

• Height: 18.9" standard; other wall heights on request.
• Footprint: standard sizes or project-specific lengths and widths.
• Rail connection: flat post cap version, or the square-rail connected version for a heavier frame.
• Playpen extension: additional panels to lengthen the run as pups become mobile.
• Access: gate or drop-in panel positions for the dam and for cleaning.
• Branding and packaging: OEM and ODM orders with customer labelling and carton marking.

How We Build and Check the Box

Production follows the same route as our fence profiles: extrusion, cutting, drilling, notching, packing and storage. Raw materials are traceable, covering virgin PVC resin, UV stabilisers and impact modifiers, with pigment and titanium dioxide from established suppliers.

• In-process inspection: each extruder's output is checked hourly, with additional random checks through the shift.
• Dimensional control: rail routing, picket length and post squareness are verified against the drawing before packing.
• Documentation: the factory holds CE, RoHS and UL94 certification and works to an ISO 9001 quality system, with SGS and ASTM test reports on file.
• Traceability: material batches are recorded so a production run can be traced back to its raw material lot.

Where an order calls for it, we can supply sample sections from the production run before the balance of the shipment is packed.

Information We Use to Configure Your Solution

A quotation for this range is prepared from the working conditions, not from a price list alone. These inputs let us confirm the frame, the packing plan and the delivery schedule in one pass.

• Breed, expected litter size and the dam's weight range.
• Required footprint and wall height, or the space the unit must fit into.
• Indoor kennel, breeding room or covered outdoor run.
• Floor type and whether the unit will be moved between rooms.
• Preferred rail connection and whether a playpen extension is needed.
• Gate or access panel positions.
• Order quantity and whether the shipment is mixed with other PVC fence items.
• Colour, labelling, carton marking and any OEM or ODM requirements.
• Destination port and required delivery window.

Packaging, Delivery and Support

Units ship flat in cartons, which keeps freight volume down and protects the routed rails in transit. Cartons can be marked with customer part numbers, and mixed loads combining whelping boxes with fence profiles such as the HEA pvc privacy panel fence 6'x8' are routine for distributors.

• Packing: carton, flat-packed, components bundled by type.
• Documentation: packing list, component schedule and installation guidance.
• Support: installation video and technical guidance for assembly and cleaning.
• Spares: replacement posts, rails, pickets and caps supplied separately.

Frequently Asked Questions

What sizes does the PVC whelping box with playpen come in?

Three standard footprints: 74.8" x 37.4" x 18.9", 90.6" x 45.3" x 18.9" and 116.6" x 58.3" x 18.9". Custom lengths and widths are produced from the same extruded profiles when a breeding room has fixed dimensions.

Can the wall height be changed?

Yes. 18.9" is our standard post height and suits newborn litters through weaning. Taller posts are available for breeders who want a higher playpen wall once pups start climbing.

Is it suitable for an outdoor kennel or run?

The PVC frame is waterproof and unaffected by damp, so it works in covered outdoor runs when placed on a hard, level surface. For adult dog containment rather than whelping, a heavier system such as the HDA 2-rail pvc farm fence is the better match.

How is the box cleaned between litters?

Disassemble the panels, wash with mild detergent and water, rinse and air dry before reassembly. The non-porous surface does not hold odour or require resealing, and stubborn marks lift with a soft abrasive cleaner suitable for sanitary plastics.

Do you accept OEM and ODM orders?

We do. Customer labelling, carton marking, colour selection and size changes are handled as part of the order, and new profile or panel layouts can be developed from a drawing or a sample.

How do I get a quotation?

Send the breed and litter size, required footprint and height, indoor or outdoor placement, quantity, destination port and any branding requirements. We reply with a professional quotation as quickly as possible and confirm the component schedule before production.
