Why choose us?

Vehicle-Impact Resistance for Security Fence

Our steel security fence meets ASTM F2656-20 standard (K12/L3 rating), capable of stopping 15,000-pound vehicles at 50 mph. Tests show perimeter breaches are reduced by approximately 78% compared to other materials.

Forced-Entry Delay for Security Fence

Per ASTM F1292 standards, our welded mesh security fence makes intrusion take about 8 minutes—roughly double the time needed for regular chain link fencing—and the high tensile strength resists bolt cutters and hydraulic cutting tools.

Electronic Integration for Security Fence

Our security fence seamlessly integrates with E-field, fiber-optic, and PIR sensors. Fiber optic sensors built into the rails pick up vibrations as small as 2mm from climbing or cutting attempts.

Frequently Asked Questions

Do you offer a warranty on your steel fences?

Yes, we stand behind the durability of our products. At Hebei Maifa, we provide a standard 10-year warranty against manufacturing defects on our steel fence panels and frames, covering issues such as weld failures or material integrity. This warranty reflects our confidence in our galvanizing and powder coating quality control procedures. For specific warranty terms, including any exclusions related to improper installation, environmental damage, or normal wear and tear, please refer to the warranty documentation included with your order or contact our after-sales team for a detailed explanation.
Our steel fences are primarily manufactured using high-quality galvanized steel grades Q195 and Q235. Q195 offers excellent formability and weldability for intricate fence designs, while Q235 provides higher strength for demanding security applications. Both materials undergo a hot-dip galvanization process with a minimum zinc coating of 80g/m² per ISO 1461 standards. This dual-layer protection—starting with the galvanized substrate and finished with an optional thermoset polyester powder coating—creates a fence system that effectively resists rust, corrosion, and UV damage, delivering a service life of 15-20 years in typical outdoor environments and over 20 years in less aggressive conditions.
The choice depends on your primary requirements. A metal fence (steel panel or aluminum) delivers superior strength, anti-climb properties, visual privacy, and a classic aesthetic—making it ideal for residential boundaries, school perimeters, commercial properties, and high-security zones. In contrast, a chain link fence offers cost-effectiveness, clear visibility, and easy installation, making it suitable for large-area applications such as sports fields, temporary storage lots, or agricultural enclosures where full visual obstruction is not needed. For a quick comparison: metal fence panels are about three times stronger in tensile strength and provide 70% better intrusion deterrence, while chain link costs approximately 40% less upfront for equivalent heights. Our technical team can assist you further based on your budget and site conditions.
Our products are designed to be space-efficient for shipping. For steel fence panels, one 20-ft container can typically fit 130 sets (one panel set = one panel + one post + accessories). A 40-ft container can fit approximately 350 sets of similar configurations. Bulk packing also reduces per-unit shipping costs. If you are ordering temporary fence panels or specialized geometries, our logistics team will provide a container capacity calculation to optimize your freight budget.

Customer Reviews

Security Director, Warehouse Logistics, Sydney

After multiple theft attempts, we installed Hebei Maifa's 358 anti-climb security fence. The 76.2x12.7mm mesh openings are impossible to grip, and the 4mm wire resisted bolt cutter attacks. Paired with their heavy-duty galvanized posts, our warehouse is now impenetrable. The security fence has a tensile strength of over 700N/mm², making it extremely difficult to cut or breach. The palisade-style top angles inward, further deterring climbing. This high-security fence gave our night crew peace of mind. The security fence panels integrate seamlessly with our camera system for a layered security approach. Absolutely top-tier protection for high-risk facilities.

CISO, Tech Company, Sydney

For our new data center, we implemented Hebei Maifa's double-layer security fence system. The outer fence features vertical slats and angled tops, while the inner fence is a 358 welded mesh. The two barriers sit six feet apart, creating a no-man's land that security studies show can slow intruders by about 80%. This security fence system integrates perfectly with our fiber-optic vibration sensors. The zinc coating on the steel ensures 25+ years of protection. For data center security and industrial sites, this security fence provides the ultimate physical barrier against determined attackers. A state-of-the-art perimeter security solution.

 358 Anti-Climb Mesh for Maximum Security

358 Anti-Climb Mesh for Maximum Security

Hebei Maifa security fence uses the world-renowned 358 mesh specification: a 3-inch (76.2mm) by 0.5-inch (12.7mm) mesh aperture with a 4mm wire diameter. This design makes the security fence nearly impossible to climb, as the small openings eliminate any foot or finger holds. The robust 4mm wire and fully welded construction also make cutting extremely difficult for bolt cutters or wire cutters. This high-security fence is very suitable for prisons, military sites, airports, and sensitive industrial facilities. With a hot-dip galvanized after-welding finish and optional polyester powder coating, our 358 security fence combines uncompromising physical protection with excellent visibility for CCTV surveillance.
