Engineered for high performance, ease of deployment, and durability in commercial, industrial, and urban environments.
In modern architectural design and municipal master planning, balancing open public access with robust physical asset protection has become a critical objective. Lockable removable bollards represent a versatile technological bridge between temporary accessibility and permanent anti-ram barrier systems. In an era marked by heightened risk profiles for critical infrastructure, public plazas, transit hubs, and government buildings, the demand for flexible access control has grown exponentially.
Unlike fixed bollards that permanently close a roadway, or automatic hydraulic systems that require complex underground power grids, drainage, and massive capital expenditures, lockable removable bollards provide a cost-effective, high-reliability mechanical solution. By utilizing a secure in-ground ground sleeve system, facility managers can manually unlock and extract the bollard in seconds to permit authorized, emergency, or utility vehicle entry, locking it back in place to restore a solid security perimeter.
A look into our state-of-the-art production hubs and institutional history of delivering globally recognized security equipment.
Established as a global pioneer in perimeter safety, KAVASS Security Tech Limited has accrued over 18 years of specialized experience in high-security metal fabrication, intelligent traffic control mechanics, and street furniture layout. We combine physical protection with mechanical engineering, catering to security agencies, public works projects, and commercial enterprises worldwide.
Our dual-manufacturing facility footprint—comprising our modern plant in Deqing and our heavy-fabrication hub in Zhuji—enables us to partition and streamline processes. The Deqing facility focuses on precision engineering, IoT smart parking integration, and final assembly, while the Zhuji factory is dedicated to heavy-duty welding, deep-draw metal presses, hot-dip galvanizing, and raw-material structural preparations. This infrastructure ensures consistent quality control and production scalability.
How our domestic ecosystem, combined with international standards compliance, delivers reliable security solutions.
We source heavy-wall structural carbon steel (Q235) and premium stainless steel alloys (SS304/SS316). Our lockable removable bollards are built with standard wall thicknesses of 3mm to 8mm, ensuring high resistance to kinetic impacts.
To withstand extreme environments, our products undergo hot-dip galvanization (according to ISO 1461 standards) followed by electrostatic polyester powder coating. This prevents oxidation even when exposed to road salt or moisture.
Our locking mechanisms utilize internal, key-actuated pin-tumbler systems or heavy shroud padlock designs, preventing unauthorized removal, picking, or environmental degradation from dirt and moisture.
| Parameter Details | Q235 Carbon Steel Bollards | 304/316 Stainless Steel Bollards |
|---|---|---|
| Common Applications | Industrial facilities, logistics parks, storefront protection | Civic centers, high-end retail, marine environments |
| Yield Strength | 235 MPa | ≥ 205 MPa |
| Standard Finish Options | Hot-dip galvanized + UV-resistant powder coat | Brushed satin finish, electropolished, mirrored |
| Locking Configurations | Internal push-lock, padlocked sleeve, key-alike/key-differ | Internal tamper-resistant profile cylinders |
| Impact Resistance | Medium to High (depending on wall thickness & foundation) | High (exceptional structural elasticity and tensile limit) |
Deploying lockable removable bollards effectively requires matching specific security requirements with site-specific conditions.
In metropolitan retail districts, pedestrian traffic is high during business hours, but delivery trucks require access at night. Installing lockable removable bollards allows city operators to block vehicle entry during the day and easily remove the barriers during designated delivery windows.
Fire lanes, hospital access routes, and evacuation pathways must remain clear of unauthorized parking while ensuring emergency services can pass. Lockable removable bollards with a master-key system or rapid triangle lock enable prompt access for emergency personnel.
High-security offices and datacenters require protection against accidental impacts and vehicle-ram attacks, while still needing access for heavy machinery maintenance. Removable stainless steel bollards provide a clean aesthetic that complements modern office facades while delivering reliable protection.
For procurement officers, municipal engineers, and security contractors, purchasing the correct physical barrier involves navigating several key performance and installation criteria:
Get answers to common technical, installation, and procurement questions from our engineering team.
A telescopic bollard retracts vertically into an underground housing, meaning it stays in place below ground level. A removable sleeve bollard is unlocked and lifted completely out of its ground socket, leaving a flush surface cover plate. Removable bollards are ideal when sub-surface utility lines prevent deep excavation.
During installation, a gravel drainage bed must be prepared beneath the sleeve to allow rainwater to drain. For high-water-table areas, KAVASS offers sleeve designs with integrated mechanical drainage valves or tight-fitting top covers to keep water out when the post is removed.
Yes. KAVASS supports OEM key cylinder integrations. We can supply bollards with euro-profile cylinders, padlock hasps, or specialized locking mechanisms that can be keyed to match your facility's master key system.
For coastal environments with high salt exposure, we recommend Grade 316 Stainless Steel with an electropolished finish. Grade 316 contains molybdenum, which provides superior resistance to chloride-induced pitting and crevice corrosion compared to Grade 304 or carbon steel.
Their impact resistance depends heavily on the wall thickness of the steel pipe and the depth and reinforcement of the concrete foundation. While they are not intended to replace high-level crash-rated barriers (like K12/M50 systems), our heavy-wall steel models provide reliable protection against low-to-medium-speed vehicle impacts.
Standard products typically ship within 15–20 days. Custom configurations—involving specific heights, wall thicknesses, custom laser-cut branding, or special paint finishes—usually have a production lead time of 30–45 days, depending on order volume and factory scheduling.
From bicycle management systems to smart IoT parking gates, KAVASS provides integrated perimeter solutions.
Whether you require standard stock items or bespoke, custom-engineered perimeter security installations, KAVASS Security Tech has the manufacturing capacity and technical expertise to deliver on your requirements.
