• Continued Work / Inspections

    For ongoing utility work, inspections, or multi-day projects, Plate Locks provide a reusable and reliable solution that eliminates the need to remove the product for continued work. Crews save time, maintain site cleanliness, and ensure road plates remain properly secured throughout the job.

  • Visibility

    Fog, rain, nighttime, and low-light conditions make steel road plates nearly invisible. Plate Locks’ bright safety-orange ramps define the entire perimeter, giving drivers, cyclists, and pedestrians an early warning — dramatically improving safety and reducing liability.

  • Heavy Duty

    Designed for heavy truck traffic, Plate Locks withstand the pressure and impact of dump trucks, excavators, and commercial vehicles. The securing systems anchors keeps plates from shifting, even under extreme loads, protecting the trench and ensuring safe passage.

  • Reusable

    Plate Locks replace single-use cold mix asphalt with a clean, reusable system that saves money every time you use it. No more messy asphalt cleanup, wasted materials, or daily re-applications — simply install, remove, and repeat for future projects.

SUSTAINABILITY


Plate Locks support city sustainability goals by replacing disposable cold patch with a reusable system that reduces material waste, repeated maintenance, and crew trips. Cold patch contains petroleum-based asphalt, oils, and may release VOCs; as it breaks apart, oily residue and loose material can enter gutters and stormwater systems. Plate Locks provide a cleaner, longer-lasting alternative.

The problems with road plates today

  • Trench Plate Fails off of Trench

    COLD PATCH

    Cold mix doesn’t actually secure road plates—it just hides the problem, breaking apart under traffic, shifting over time, and requiring constant reapplication without ever anchoring the plate in place.

  • BIKE LANE HAZARD

    An unramped plate creates a sharp edge that can catch a bicycle tire, causing cyclists to lose control and crash.

  • CAR ACCIDENTS

    Unsecured road plates can shift under traffic, creating dangerous gaps that can cause vehicles to drop into the trench below.

  • FLUSH MOUNT

    Flush mounting metal road plates—where the plate is set level with the road surface—requires saw-cutting the pavement, excavating material, and often backfilling or pouring concrete around the edges. This process is labor-intensive, time-consuming, and expensive, often costing thousands of dollars per plate.

  • TIRE SHREDDERS

    Due to the flexing of metal plates under traffic, railroad spikes can work their way loose and get pushed upward—turning them into dangerous tire shredders.

  • PEDESTRIAN SAFETY

    Ramps on road plates used on sidewalks are important because they provide a smooth, accessible transition for pedestrians, wheelchairs, strollers, cyclists, and preventing trips.

  • POLLUTION

    Cold mix asphalt is a petroleum-based, non-reusable material that degrades quickly, contributing to material waste and hydrocarbon runoff in storm drains.

  • UNSECURED PLATE

    Unsecured plating is dangerous because it can shift or slide under traffic, creating trip hazards, vehicle damage, noise complaints, and exposing open trenches to the public.
