Pvc whelping box use square rail connected

Deqing Huazhijie Railing & Fencing Co.,Ltd. is a China-based PVC profile manufacturer producing fence, railing and pet enclosure systems from our factory in Huzhou, Zhejiang, near Shanghai. The PVC whelping box use square rail connected manufacturer line is our dedicated breeding enclosure: a 100% virgin PVC box built from square posts and pre-routed rails, supplied flat-packed in cartons for breeders, kennels, veterinary clinics and pet product distributors who need a washable, chew-resistant whelping space instead of a fabric pen.

What the Square Rail Whelping Box Is and Where It Fits

This is a modular whelping enclosure rather than a fixed piece of furniture. Four square posts carry pre-routed rails, and the rail run incorporates a wide pig rail that gives newborn puppies a ledge to crawl onto and away from the dam's weight. Because every part is a PVC extrusion, surfaces wipe down, do not absorb urine or bedding moisture, and do not splinter the way timber boxes can.

• Primary use: whelping and the first weeks of puppy rearing, indoors or in a climate-controlled kennel room.
• Typical customers: breeding kennels, veterinary practices, pet distributors and retailers, and OEM customers building their own branded pet lines.
• Why PVC here: waterproof, easy to clean, no rot, no termites and no lead in the formulation.

Breeders who also run outdoor exercise areas commonly pair the box with our HDB 3-rail pvc horse fence for perimeter runs, or with HAF 1"x1" small picket fence where small-animal containment is the priority.

Standard Sizes, Posts and Rail Geometry

Three square footprints cover most breeding programmes, all at the same 18.9" wall height so the dam can step in and out without a ramp. Post height can be changed when a taller wall is required for larger breeds or for a box that continues in service as a puppy playpen.

Design Details That Matter During Whelping

The square rail connection is the structural idea behind the box: rails seat into routed openings in the posts, so the frame stays rigid when the dam leans against a wall or steps over the rail line. Nothing protrudes into the puppy zone, which keeps the interior surface smooth and quick to wipe between litters.

• Wide pig rail: the pre-routed 7/8" x 6" rail carries a wide pig rail, giving newborns a protected strip along the wall.
• 18.9" wall height: contains newborns while remaining low enough for the dam to step in and out.
• 3" x 3" square posts: a substantial bearing section that resists racking under repeated cleaning and handling.
• Flat caps and post feet: caps close the post tops; feet spread load and reduce scuffing on tiled or concrete floors.
• Waterproof body: urine, whelping fluids and disinfectant do not soak into the material.

Material, Extrusion and Quality Control

Every component begins as a PVC extrusion on our own lines, which is why wall section, colour consistency and routing accuracy are controlled in one place. The formulation is 100% virgin vinyl with no recycled material and no lead, using US DuPont TiO2 at 10 parts per 100, US or German pigments and domestically made PVC resin, all traceable back to the batch.

Quality control operates as an independent function in our Huzhou factory. Each extruder's output is inspected every hour, with additional random checks across the shift, and the production sequence — extrusion, cutting, drilling, notching, packing, storage — is documented step by step.

• CE, RoHS and UL94 documentation held by the company.
• SGS, ASTM, ISO 9001 and TUV Global Manufacturer Certificate.
• PVC formulation stated to perform from -40 to 70 degrees.
• Lead-free, environmentally friendly PVC throughout the range.

Configuration Options and OEM/ODM Work

Standard configurations ship from the three footprints above, and both post height and overall dimensions can be adjusted for a specific breeding programme. Because we extrude the profiles ourselves, a new rail or post section for a pet enclosure is a tooling and routing exercise rather than a sourcing problem.

• Size: three standard square footprints, plus customer-made sizes.
• Height: 18.9" posts as standard, other post heights available.
• OEM and ODM: welcomed, including profile development and style adaptation.
• Range depth: more than 500 PVC profile styles across fence, railing and pet products.

Assembly, Placement and Cleaning

The box arrives flat and assembles by seating the pre-routed rails into the posts, then fitting the flat caps and post feet. No cutting, drilling or notching is required on site, and we supply an installation video plus technical support for first-time assembly.

• Floor: a level, hard, washable surface gives the most stable result; post feet protect tiles and coated concrete.
• Location: indoor whelping rooms and climate-controlled kennel buildings are the intended setting.
• Cleaning: rinse and wipe with a mild cleaner; the material is waterproof and does not retain odour.
• Bedding: flat, absorbent bedding sits inside the rail line without fouling the pig rail.

Packing, Delivery Scope and Documentation

Each unit is packed in a carton as a complete kit: square posts, pre-routed rails, flat caps and post feet. Carton quantities are consolidated for container loading, and OEM labelling or private-label packaging can be arranged with the order.

• Component kit packed per box, bundled for straightforward site handling.
• Installation video and technical guidance supplied with the order.
• Certificate documentation available for import and compliance files.
• Export experience across Canada, the USA, Europe, Australia and New Zealand.

Information We Use to Configure Your Solution

A quotation is prepared from the working point rather than from a catalogue line. The details below let us confirm the right footprint, post height and packing format the first time.

• Breed and litter size: determines whether the 37.4", 45.3" or 58.3" footprint is the correct starting point.
• Wall height required: standard 18.9" or a taller post for larger dams.
• Quantity and mix: how many units per size, and whether sizes are ordered together.
• Use environment: whelping room, clinic, kennel building or retail display.
• Branding and packaging: OEM/ODM requirements, labelling and carton marking.
• Delivery destination: port, warehouse or project site, with target shipping window.

Frequently Asked Questions

What sizes does the PVC whelping box come in?

Three standard square footprints: 37.4"L x 37.4"W, 45.3"L x 45.3"W and 58.3"L x 58.3"W, all at 18.9" height. Customer-made sizes are also available when a breeding programme needs a different footprint.

Is the box safe for newborn puppies?

The pre-routed 7/8" x 6" rail carries a wide pig rail, which gives puppies a protected strip along the wall where the dam cannot lie on them. The 18.9" wall keeps newborns contained, and the square rail connection keeps the frame rigid without fittings protruding into the interior.

What material is used, and is it lead-free?

The frame is 100% virgin PVC with no recycled material and no lead. We use US DuPont TiO2 at 10 parts per 100 together with US or German pigments and domestically made PVC resin, and the raw materials are traceable back to the batch.

Can the box be used outdoors or in a kennel building?

The material is waterproof and unaffected by moisture, so it suits covered kennel buildings and wash-down rooms. For open outdoor use, a level hard surface and the supplied post feet give the most stable installation, and the box can be moved indoors as the litter grows.

Do you accept OEM and ODM orders for pet enclosures?

Yes. We welcome OEM and ODM orders, including new profile development, size changes and private-label packaging. Our engineering team reviews the intended use and proposes the rail section, post height and routing that fit it.

How is the whelping box packed and shipped?

Each unit ships as a carton kit containing square posts, pre-routed rails, flat caps and post feet. Cartons are consolidated for container loading, and an installation video plus technical support is provided with the order.
