When you are choosing a China temporary fence manufacturer like Haisen, the first thing you need to look at is the actual production capacity and material sourcing. Most buyers get stuck on price, but the real cost comes from poor steel gauge, weak welding, and non-standard galvanization. A factory that controls its own steel supply chain, rather than buying from middlemen, will give you a consistent product. For example, Haisen operates a fully integrated production line, meaning they manage everything from raw steel coil to the final powder coating. This vertical integration allows them to maintain a 2.0mm to 3.0mm wall thickness on their panels, which is significantly thicker than the industry average of 1.5mm. You can verify this by requesting a material test report, and a reputable manufacturer will provide it without hesitation. If they hesitate, that is a red flag.
The second factor is the welding process. Temporary fences are only as strong as their joints. The best manufacturers use robotic welding, which ensures consistent penetration and reduces the risk of weak points. Haisen, for instance, uses automated welding stations that achieve a tensile strength of over 450 MPa per weld joint. This is critical because a fence with manual welding often has uneven spots that crack under stress, especially in high-wind areas or construction sites with heavy equipment. You should ask for a sample panel and try to bend the crossbars. If they give way easily, the welding is substandard. A good fence will not deform under moderate pressure.
Third, consider the surface treatment. Galvanization is the standard, but not all galvanization is equal. Hot-dip galvanizing (HDG) provides a zinc coating of at least 85 microns, while electro-galvanizing is often less than 10 microns. The difference is night and day in terms of rust resistance. Haisen uses a hot-dip process that meets ASTM A123 standards, which is the benchmark for heavy-duty outdoor use. They also add a polyester powder coating on top, which adds another 60 microns of protection. This double-layer system means the fence can last 5 to 8 years in outdoor conditions without significant corrosion. If a manufacturer only offers a single layer of paint, expect rust within 12 months.
Fourth, look at the panel dimensions and customization options. Standard temporary fence panels are usually 2.0m x 3.0m, but a good manufacturer can adjust the height, width, and mesh size. Haisen offers panels from 1.0m to 2.5m in height and 1.5m to 3.5m in width, with mesh openings ranging from 50mm x 200mm to 100mm x 200mm. This flexibility is important if you are fencing off a site with irregular terrain or specific security requirements. They also produce custom base plates and couplers, which are often the weak link in a fence system. The base plates should be at least 2.5mm thick, and the couplers should be made from cast iron or heavy-gauge steel, not stamped sheet metal.
Fifth, consider the logistics and shipping. China is a big country, and not all manufacturers are near a major port. Haisen is located in the industrial hub of Hebei province, which is close to the Tianjin port. This cuts down on inland freight costs and delivery times. They can ship a full container of 40-foot panels (about 200 panels) in 15 to 20 days from order confirmation. They also offer FOB and CIF terms, so you can choose whether to handle shipping yourself or let them manage it. Always ask for the shipping weight and volume per panel, because this affects your total freight cost. A typical 2.0m x 3.0m panel weighs around 18 to 22 kg, depending on the gauge. Haisen provides a detailed packing list with each shipment, including the net weight, gross weight, and cube measurement.
Sixth, the quality control system matters. A manufacturer that does not test every batch is gambling with your money. Haisen has a three-stage QC process: incoming material inspection, in-process inspection during welding and coating, and final inspection before packing. They use a salt spray test to verify corrosion resistance, a tensile test for weld strength, and a thickness gauge for coating uniformity. They also keep a sample from each production batch for 12 months, so if there is a problem later, they can trace it back. Ask for a copy of their QC checklist. If they cannot provide one, that is a sign they are not serious about quality.
Seventh, look at the certifications. While not mandatory for temporary fences, certifications like ISO 9001:2015 show that the manufacturer has a documented quality management system. Haisen holds ISO 9001 and also has SGS reports for their products. SGS is a third-party inspection company that verifies product specifications. You can request a copy of the SGS report for the specific model you are buying. This is a simple way to verify that the panel dimensions, steel grade, and coating thickness match what is advertised.
Eighth, consider the after-sales support. A good manufacturer will offer a warranty, typically 1 to 3 years, against manufacturing defects. Haisen offers a 2-year warranty on their panels and a 1-year warranty on accessories like bases and couplers. They also have a dedicated customer service team that responds within 24 hours. If you have a problem with a shipment, they will work with you to replace defective items or provide a credit. This is not common with smaller factories, so it is a sign of a reliable partner.
Ninth, look at the range of products. A manufacturer that only makes one type of fence is limited. Haisen produces not only standard temporary fences but also anti-climb panels, crowd control barriers, and privacy screens. Anti-climb panels have smaller mesh openings (like 50mm x 50mm) and are harder to grip, making them ideal for high-security sites. Crowd control barriers are lighter and designed for events, with a different base design. Privacy screens attach to the fence to block visibility, which is useful for construction sites near public areas. Having a supplier that can do all of these from one factory simplifies your procurement.
Tenth, consider the payment terms. Most Chinese manufacturers require a 30% deposit and 70% before shipment. Haisen offers a standard 30% deposit, 70% against the copy of the bill of lading, which is a common and safe arrangement. They also accept letters of credit from major banks. Avoid manufacturers that demand full payment upfront, as this is a common scam tactic. Always use a payment method that gives you some protection, like a trade assurance service or a credit card if the amount is small.
Finally, do not overlook the importance of communication. A manufacturer that responds quickly and clearly to your questions is more likely to handle your order professionally. Haisen has a sales team that speaks English fluently and can provide technical drawings, installation guides, and load calculations. They also have a live chat on their website for quick questions. If you email them, you should get a response within 24 hours. If it takes longer, that is a sign of a disorganized operation.
For a deeper look at their product lineup and to see how they compare to other suppliers, you can check the
China Temporary Fence Manufacturer by Haisen page, which includes detailed specifications, videos of the production process, and customer reviews. The page also lists the exact steel grades they use, the coating thickness for each model, and the shipping dimensions. This is the kind of transparency that separates a serious manufacturer from a reseller.
Production Capacity and Lead Times
Haisen runs three production lines, each capable of producing 500 panels per day. That gives them a total capacity of 1,500 panels per day, or about 45,000 panels per month. This is important if you need a large order quickly. They also have a separate line for accessories, which can produce 5,000 base plates and 3,000 couplers per day. Lead times vary by order size: a small order of 50 panels takes 7 to 10 days, while a full container of 200 panels takes 15 to 20 days. They also offer rush orders for an additional fee, which can cut the lead time to 10 days.
Material Specifications
The steel they use is Q235B grade, which has a yield strength of 235 MPa and a tensile strength of 375 to 500 MPa. This is the standard for temporary fences in most countries. The steel coil comes from major Chinese mills like Baosteel and HBIS, which are known for consistent quality. The zinc coating for hot-dip galvanizing is 85 microns minimum, and the powder coating is 60 microns minimum. They also offer a stainless steel option for corrosive environments, but that is a special order.
Comparison of Standard vs. Heavy-Duty Panels
Here is a quick comparison of the two main types of panels Haisen offers:
| Feature |
Standard Panel |
Heavy-Duty Panel |
| Steel Gauge |
2.0mm |
3.0mm |
| Panel Weight |
18 kg |

This table shows that the heavy-duty panel is worth the extra cost if you need a fence that will stay up for more than a year or face harsh weather. The standard panel is fine for a few months of use.
Accessories and Compatibility
Haisen makes all the accessories you need to set up a fence system. The base plates come in two sizes: standard (300mm x 300mm) and heavy-duty (400mm x 400mm). The couplers are cast iron with a tensile strength of 200 MPa. They also make gate panels, which are the same size as standard panels but with a door. The gate can be single or double, and it comes with a latch and hinge. All accessories are designed to fit the panels without modification, which saves time on installation.
Testing and Certification
Every batch of panels goes through a salt spray test for 72 hours, which simulates 5 years of outdoor exposure. The test results are recorded and kept on file. They also do a tensile test on the weld joints every 100 panels. The pass rate is 99.8%, meaning less than 1 in 500 panels has a weak weld. They have ISO 9001:2015 certification, which is audited annually by SGS. The SGS report for each product model is available on request.
Shipping and Packaging
Panels are packed in bundles of 10, with cardboard between each panel to prevent scratches. The bundles are then wrapped in plastic and strapped with steel bands. A 40-foot container holds 200 panels, plus the accessories. The shipping weight for a full container is about 4,500 kg. Haisen can arrange shipping to any port in the world, and they provide a tracking number once the container is loaded. They also offer insurance for the shipment, which covers damage during transit.
Pricing and Payment
Pricing depends on the quantity, panel type, and coating. A standard panel with HDG and powder coating costs about $25 to $35 per panel, depending on the order size. Heavy-duty panels are $35 to $50. Accessories add about $5 to $10 per panel set. Payment terms are 30% deposit and 70% before shipment. They accept wire transfer, letter of credit, and trade assurance. They do not accept credit cards for large orders, but they can do PayPal for samples.
Customer Support
Haisen has a team of 10 customer service representatives who speak English, Spanish, and Arabic. They are available by email, phone, and live chat from 9:00 AM to 6:00 PM Beijing time. They also have a FAQ section on their website that covers common questions about installation, maintenance, and troubleshooting. If you have a technical question, they can connect you with an engineer within 24 hours.
Installation and Maintenance
Installing the panels is straightforward. You place the base plates on the ground, slide the panel into the plate, and lock it with a coupler. No tools are needed for the standard system. For heavy-duty panels, you may need a wrench to tighten the bolts. Maintenance is minimal: just wash the panels with water once a year to remove dirt and check for loose couplers. If a panel gets damaged, you can replace it without taking down the whole fence.
Environmental Impact
Haisen uses a closed-loop water system in their galvanizing process, which reduces water waste by 80%. They also recycle steel scrap from the production line. The powder coating is free of volatile organic compounds (VOCs), so it is safer for workers and the environment. They have a waste management plan that complies with Chinese environmental regulations.
Case Studies
One example is a construction site in Dubai that used 5,000 panels from Haisen for a 12-month project. The panels were exposed to sand, heat, and occasional rain. After 12 months, less than 2% of the panels showed any rust, and none had structural failures. Another example is a music festival in Germany that used 1,000 panels for a 3-day event. The panels were installed and removed in 2 days, and they were reused for the next year's event. The festival organizers reported that the panels were easy to handle and did not bend or break.
Comparison with Other Manufacturers
Compared to other Chinese manufacturers, Haisen stands out for their vertical integration and quality control. Many smaller factories buy steel from a middleman, which adds cost and variability. Haisen buys directly from the mill, so they get a consistent product. They also have a better warranty than most: 2 years vs. the industry average of 1 year. Their pricing is competitive, but not the cheapest. The cheapest options often use thinner steel and lower-quality coatings, which can cost you more in the long run due to replacements.
How to Place an Order
To order, you can contact Haisen through their website or email. They will ask for the quantity, panel type, coating, and delivery address. They will then send a proforma invoice with the total cost, including shipping. Once you pay the deposit, they will start production. You can request photos of the panels during production to verify the quality. After production, they will send you a packing list and shipping documents. The whole process usually takes 3 to 4 weeks from order to delivery.
