Protect Your Facility withHeight Restriction Barriers
Prevent costly overhead damage from oversized vehicles. Professional-grade steel barriers for parking structures, loading docks, drive-throughs, and commercial properties.
Barrier Types
Choose the Right Barrier System
Different facilities need different solutions. From permanent fixed barriers to flexible swing-open systems, we offer the right height restriction for every application.
Fixed Goal-Post Barriers
The most common configuration for permanent height control. Two vertical steel posts support a horizontal crossbar at the designated clearance height. Ideal for parking garage entrances, underpasses, and any location where tall vehicle access is never required.
Best for: Parking garages, tunnels, underpasses
Swing-Open Barriers
Feature a hinged crossbar that can be unlocked and swung upward or to the side, allowing occasional access for taller vehicles like delivery trucks, refuse lorries, or emergency vehicles. The best choice when a site needs height control most of the time but periodic tall-vehicle access.
Best for: Loading docks, service entrances, mixed-use facilities
Telescopic & Adjustable Barriers
Height can be adjusted after installation to accommodate changing clearance requirements. Telescopic posts allow the crossbar to be raised or lowered as needed. Useful for facilities that serve multiple vehicle types or where regulations may change.
Best for: Multi-use facilities, temporary restrictions, evolving sites
Applications
Where Height Barriers Are Used
Any facility with overhead structures vulnerable to vehicle impact can benefit from a properly designed height restriction barrier system.
Parking Structures
Multi-storey and underground car parks are the most common application. Barriers protect low ceilings, sprinkler systems, lighting, ventilation ducts, and structural beams from impact by oversized vehicles.
Loading Docks & Warehouses
Control which vehicles can access low-clearance bays and internal warehouse areas. Swing-open barriers allow authorized delivery trucks through while keeping unauthorized oversized vehicles out.
Drive-Throughs
Fast food restaurants, banks, and pharmacies use height barriers to prevent large vehicles from damaging canopy structures, speaker systems, and overhead signage in drive-through lanes.
Retail & Commercial Properties
Shopping centers, fuel stations, and commercial plazas use height barriers to protect covered walkways, awnings, fuel canopies, and decorative architectural features from vehicle strikes.
Bridges & Underpasses
Municipalities install advance-warning height barriers upstream of low bridges and tunnels. These give drivers clear notice to stop or detour before reaching the actual structure.
Residential & Mixed-Use
Apartment complexes and mixed-use developments use height barriers in underground parking and covered areas to prevent damage from moving trucks, delivery vans, and recreational vehicles.
Why Install Barriers
The Case for Height Restriction Barriers
For every dollar spent on barrier installation, facilities save thousands in avoided damage, liability claims, and operational disruptions.
Prevent Costly Structural Damage
A single strike from an oversized vehicle can cause tens of thousands of dollars in repairs to ceilings, sprinkler systems, HVAC ducts, and structural beams. Height restriction barriers eliminate this risk entirely by stopping vehicles before they reach vulnerable overhead infrastructure.
Reduce Liability Exposure
Without proper vehicle height control, property owners face significant liability for injuries to drivers, passengers, and pedestrians resulting from overhead collisions. A properly installed and marked barrier system demonstrates due diligence and shifts liability away from the property.
Minimize Facility Downtime
When an oversized vehicle damages overhead infrastructure, the affected area often needs to be closed for inspection and repair — shutting down parking levels, blocking loading docks, or closing drive-throughs. Barriers prevent incidents that lead to revenue-losing closures.
Low Cost, High ROI
A height restriction barrier typically costs a fraction of a single repair bill. With virtually no moving parts (fixed barriers) and galvanized steel construction rated for decades of service, the return on investment is immediate and the ongoing cost is near zero.
