If you’re sourcing heavy-duty dog kennels for commercial breeding, boarding, or retail, the Dog Kennel Manufacturer by Hebei Haisen stands out because of its vertically integrated production, strict material sourcing, and export-grade quality control. Unlike many suppliers who only assemble parts, Hebei Haisen controls the entire chain—from raw steel procurement to final powder coating. This means you get consistent wall thickness, uniform weld strength, and corrosion resistance that actually holds up in high-moisture environments. Their factory in Anping County, Hebei Province—the “Wire Mesh Capital of China”—gives them direct access to Q195 and Q235 low-carbon steel wire, which is the backbone of their kennel panels. They use wire diameters ranging from 3.0mm to 6.0mm depending on the model, and the gap spacing typically runs between 50mm and 100mm to prevent dogs from sticking their heads through or getting paws caught. The entire line is hot-dip galvanized after welding, not just electroplated, which adds a zinc coating thickness of 40–60 microns per ASTM A123 standards. That’s a key detail because many budget kennels only spray a thin layer of paint that chips off within six months outdoors. Hebei Haisen’s panels are tested for salt spray resistance up to 200 hours in their in-house lab, which is a real number you can verify if you request a test report. They also offer an optional electrostatic powder coating layer in RAL colors, which adds another 60–80 microns of protection and gives you a finish that doesn’t fade under UV exposure for at least 3 years in direct sunlight. The hinges are another area where you see the difference—they use 304 stainless steel rivets instead of mild steel pins, which eliminates rust at the pivot point. The latch system is a spring-loaded slide bolt with a padlock hole, designed so that a strong dog can’t shake it open. For commercial users, they can produce kennels with reinforced corners using 12-gauge steel brackets, which increases the load capacity of the assembly to over 200 kg per panel. That’s important if you’re housing large breeds like Mastiffs or Great Danes. The base of each kennel can be ordered with a removable plastic tray instead of a wire floor, which is a huge plus for hygiene because you can pull it out and hose it down without moving the dog. The tray is made from HDPE (high-density polyethylene) with a thickness of 2.5mm, and it’s UV-stabilized so it won’t become brittle after a year in the sun. They also offer custom sizes—if you need a 6-foot by 10-foot run with a 4-foot height, they can weld it to your spec without a minimum order quantity up to 50 units. The turnaround time for a standard 20-foot container (which holds roughly 120–150 assembled kennels depending on size) is 25–30 days from order confirmation. That’s faster than most competitors because they keep a rolling stock of 10,000 square meters of pre-galvanized wire mesh in their warehouse. Their export documentation includes a full packing list, bill of lading, and a certificate of origin from the China Chamber of Commerce, which helps you clear customs smoothly in the US, EU, or Australia.

Let’s break down the specific features that matter most when you’re buying in bulk or for a facility that needs to last.
Material Quality and Wire Specifications
The foundation of any kennel is the wire itself. Hebei Haisen uses Q195 low-carbon steel wire with a tensile strength of 315–430 MPa, which is the standard for general metalworking but they add a cold-drawing process that increases the yield strength to around 350 MPa. That means the wire is less likely to bend or deform under pressure from a dog jumping against it. They offer three grades of galvanization: standard hot-dip (40–60 microns), heavy hot-dip (60–80 microns), and a super-heavy option (80–100 microns) for coastal or high-humidity areas. The heavy hot-dip grade is the most popular for international buyers because it passes the 72-hour salt spray test without any red rust. The wire diameter varies by panel size—for a standard 4-foot by 8-foot panel, they use 4.0mm wire for the main mesh and 5.0mm for the frame. The frame is welded from 1-inch square tubing with a wall thickness of 1.2mm, which is thicker than the 0.8mm tubing you often see in cheaper kennels. The welding points are robotically welded using a MIG process with a penetration depth of at least 1.5mm, so the joints don’t separate even if a dog repeatedly bites or shakes the panel. They test every 100th panel with a destructive pull test—a hydraulic machine pulls the weld until it breaks, and the minimum acceptable force is 800 Newtons per weld point. That data is recorded and available in their quality control log if you request it. For the mesh pattern, they use a diamond or square grid, with the diamond pattern being stronger because the diagonal wires distribute force more evenly. The standard gap is 50mm x 50mm for small breeds and 100mm x 100mm for large breeds, but they can custom-make any gap from 25mm to 150mm. If you’re housing puppies, they recommend a 25mm gap to prevent escape, and they can add a second layer of finer mesh at the bottom 12 inches of the panel. That’s a detail that reduces the risk of small dogs or puppies slipping through, which is a common complaint with standard kennels.
Structural Design and Assembly
The kennel panels are designed to be bolted together, not welded on-site, which makes shipping and setup much easier. Each panel has pre-drilled holes at 6-inch intervals along the frame, and the bolts are 8mm diameter zinc-plated steel with nylon lock nuts. The lock nuts are critical because they prevent vibration loosening over time—if a dog shakes the kennel door, the nuts stay tight. The panels are connected using a corner bracket system that uses 1.5mm thick steel plates with four bolt holes. This creates a rigid 90-degree joint that doesn’t flex, even when the kennel is fully assembled and moved around. The roof panels are a separate piece that sits on top of the side panels and is secured with spring clips. The roof can be flat or sloped, with the sloped version allowing rainwater to run off. The slope is 15 degrees, which is enough to prevent water pooling but not so steep that it adds height. The roof panels are made from the same wire mesh as the walls, but they can be ordered with a solid galvanized steel sheet overlay if you want to provide shade or protection from snow. The solid overlay adds about 8 kg per panel, so you need to factor that into the shipping weight. The door is a separate panel with a hinged frame and a double-latch system. The primary latch is a spring-loaded slide bolt that goes into a receiver on the top and bottom of the door frame. The secondary latch is a padlock hasp welded to the door and frame, so you can add a padlock for security. The hinges are butt hinges with 304 stainless steel pins, and they’re welded to the frame at three points—top, middle, and bottom. The pin diameter is 6mm, which is thick enough to resist being bent by a strong dog. The door opening is typically 24 inches wide by 36 inches tall, but you can request up to 36 inches wide for large breeds. The door swings inward, which is safer for the dog because it prevents them from pushing the door open and escaping. The kennel can be assembled by two people in about 30 minutes using a socket wrench and a rubber mallet. The panels are numbered and the bolt kit comes with a diagram, so you don’t need to guess which panel goes where. The total weight of a standard 4-foot by 6-foot kennel with a 4-foot height is about 45 kg for the panels and hardware, plus another 10 kg for the tray if you order it. That’s a manageable weight for shipping, and it fits in a standard 20-foot container without needing special crating.
Customization Options and Flexibility
One of the biggest advantages of working with a manufacturer like Hebei Haisen is the ability to customize every aspect of the kennel. You can change the panel dimensions, wire gauge, mesh pattern, coating color, and even the type of tray. The minimum order for custom sizes is 50 units, but for standard sizes they accept orders as low as 10 units. They have a library of over 200 standard sizes, ranging from a small 2-foot by 3-foot kennel for a single Chihuahua to a 10-foot by 20-foot run for a kennel facility. You can also order a kennel with a divider panel that splits the space into two sections, which is useful for temporary separation of dogs. The divider panel is the same gauge as the walls and slides into a track system that bolts to the side panels. The track is made from 2-inch C-channel steel, and the divider has a locking pin that holds it in place. You can also add a feeding door—a small 8-inch by 10-inch cutout in the side panel with a sliding cover that lets you put food and water bowls in without opening the main door. The feeding door is reinforced with a steel frame and has a spring-loaded latch that the dog can’t open. For outdoor kennels, you can order a windbreak panel that attaches to the side and blocks wind from one direction. The windbreak is a solid galvanized steel sheet that bolts to the outside of the mesh, and it’s available in heights from 12 inches to 36 inches. They also offer a raised floor option, where the kennel sits on 4-inch legs that elevate it off the ground. This is important for drainage and airflow, and it prevents the kennel from sitting in mud or water. The legs are made from 1.5-inch square tubing with rubber feet that protect the floor. The raised floor adds about 15 kg to the total weight and costs an extra 15% on top of the base price. If you’re buying for a breeding facility, they can add a whelping box insert that fits inside the kennel. The insert is a 2-foot by 3-foot box with 6-inch high walls and a removable floor, made from the same galvanized wire mesh. It keeps the puppies contained while allowing the mother to come and go. The insert is secured with clips and can be removed when not in use.
Quality Control and Testing Protocols
Hebei Haisen has a quality control system that follows ISO 9001 standards, and they have a dedicated QC team of 12 people who inspect every batch. The inspection process starts with the raw wire—they test the tensile strength and zinc coating thickness of every coil using a portable spectrometer and a magnetic thickness gauge. If the wire doesn’t meet the spec, they reject the entire coil. After welding, the panels go through a visual inspection for weld defects, then a dimensional check using a laser measuring tool that verifies the panel is within 2mm of the specified size. They also do a random bend test on 1% of the panels—they clamp the panel in a hydraulic press and apply a force of 500 N to the center of the mesh. If the panel deforms more than 10mm, the entire batch is re-welded. After galvanization, they test the coating thickness at five points on each panel using an eddy current gauge. The minimum acceptable thickness is 40 microns, and the average is usually 50–55 microns. For the powder coating option, they do a cross-hatch adhesion test to make sure the paint doesn’t peel off. They also do a salt spray test on one panel per batch, running it for 200 hours in a chamber that sprays a 5% salt solution at 35°C. The panel must show no red rust after 200 hours, and only white rust (which is cosmetic) is allowed. They provide a certificate of analysis for each batch that includes the test results, and you can request a third-party inspection from SGS or Bureau Veritas at your own cost. The factory is open for visits, and they have a showroom with 20 different kennel models set up so you can see the quality in person. They also have a video feed of the production line that you can request to see live, which is a good way to verify that the factory is actually producing the kennels and not just reselling them. The QC team keeps a log of all defects and the corrective actions taken, and they can share this data with you if you’re doing a long-term contract. The defect rate for the last year was 0.3%, which means 3 out of every 1,000 panels had a minor issue like a scratch or a slightly misaligned hole. They replace any defective panel free of charge, including shipping, within 30 days of delivery.
Shipping and Logistics
The factory is located in Anping County, which is about 200 km from Tianjin Port, one of the busiest container ports in China. They use a dedicated freight forwarder who handles all the export paperwork, including the customs declaration, fumigation certificate for the wooden pallets, and the bill of lading. The standard shipping method is FOB (Free on Board) Tianjin, which means you arrange the ocean freight from the port. They also offer CIF (Cost, Insurance, and Freight) to major ports like Los Angeles, Rotterdam, or Sydney, which includes the shipping cost in the price. The lead time for a standard order is 25–30 days after you confirm the order and pay the deposit. The deposit is usually 30%, with the balance due before shipment. They accept payment by T/T (wire transfer) or L/C (letter of credit) for large orders. The kennels are packed in bundles of 5 panels per bundle, wrapped in stretch film and strapped to wooden pallets. The hardware (bolts, nuts, clips, and tools) is packed in a separate box that is taped to the top of the first bundle. The pallets are shrink-wrapped and banded with steel straps to prevent movement during transit. For a 20-foot container, you can fit about 120–150 kennels depending on the size. For example, a 4-foot by 6-foot kennel takes up about 0.8 cubic meters, so you can fit roughly 120 units in a 20-foot container (which has 33 cubic meters of usable space). A 40-foot container can hold about 250 units. The shipping cost from Tianjin to Los Angeles is typically $2,500–$3,500 for a 20-foot container, depending on the current freight rates. The transit time is about 20–25 days to the West Coast of the US, and 30–35 days to the East Coast or Europe. They offer a tracking number for every shipment, and you can monitor the container’s location via the carrier’s website. They also have a warehouse in the US (in California) where they keep a small stock of the most popular sizes for faster delivery. If you order from the US warehouse, the lead time is 5–7 days, but the price is about 10–15% higher because of the warehousing and handling costs. For orders under 50 units, they recommend ordering from the US warehouse if you’re in North America, because the shipping cost from China for a small order can be higher than the product price.
Pricing and Payment Terms
The pricing is competitive because Hebei Haisen manufactures in volume and controls the raw material costs. A standard 4-foot by 6-foot kennel with a 4-foot height, hot-dip galvanized, with a plastic tray, costs about $85–$110 per unit FOB Tianjin, depending on the order quantity. For 100 units, the price is around $95 per unit. For 500 units, it drops to $85 per unit. The powder coating option adds $5–$10 per unit depending on the color. The heavy-duty galvanization (80–100 microns) adds $8–$12 per unit. The raised floor option adds $12–$18 per unit. The feeding door adds $5 per unit. The divider panel adds $15–$20 per unit. The solid roof overlay adds $10–$15 per unit. The prices are ex-works, so you need to add the cost of packaging (about $2 per unit) and the freight forwarder fees (about $50 per order). They offer a 5% discount for orders over 1,000 units, and a 10% discount for orders over 5,000 units. The payment terms are 30% deposit with the order, 70% before shipment. They accept T/T, L/C, and for small orders under $5,000, they accept PayPal (with a 3% fee). They also offer a sample order service—you can order one unit at the full price plus shipping, and they will deduct the sample cost from your first bulk order. The sample takes about 15 days to produce and ship via express (DHL, FedEx, or UPS), and the shipping cost is about $80–$120 depending on your location. The sample is a good way to test the quality before committing to a large order, and they will send you the test reports for that sample batch. They also have a warranty policy: 12 months from the date of shipment for manufacturing defects. The warranty covers weld failure, coating peeling, and hinge breakage. It does not cover damage from misuse, abuse, or natural wear and tear. If you have a defect, you send them photos and a description, and they will either send a replacement part or a full replacement panel, depending on the severity. The replacement is shipped at their cost, and you don’t need to return the defective item.
Applications and Use Cases
These kennels are used in a wide range of settings. Commercial boarding kennels buy them in bulk because they can stack them in rows and create runs of any length. The modular design means you can connect multiple kennels together by removing the side panels and using a shared wall. This reduces the cost per run and makes cleaning easier because you can walk through the rows. Veterinary clinics use them for post-surgery recovery, where the solid tray option is preferred because it’s easier to disinfect. The tray is non-porous, so it doesn’t harbor bacteria, and it can be cleaned with bleach or
