National Guard Products Heavy Duty Thresholds

Key Features

• Ultra-thick, heavy-gauge aluminum construction for long-term durability under extreme load conditions.
• Load capacity up to 10,000 lbs tested per BHMA ANSI A156.21 Heavy Duty standards for vehicular/forklift applications.
• Skid-resistant surfaces: PemKote™ non-slip coating (Pemko) or SIA slip-resistant finish (NGP) for moisture-prone and high-humidity areas.
• Multiple width/height options: ranging from 2" transition strips to 6" wide × 1/4" low-profile forklift thresholds, up to 5" × 1/2" standard heavy-duty saddles.
• Fire-rated & ADA compliant: certified for use on labeled fire door assemblies and meets ADA Accessibility Guidelines with a maximum 1/2" rise.
• Coastal & high-humidity resistant: aluminum construction won't corrode in marine environments or humid industrial settings.
• Standard & custom lengths: available in 36", 48", 72", 80", 96", and custom-cut sizes up to 104" (larger sizes available via special order).

Key Benefits

• Withstands vehicular traffic including forklifts, pallet jacks, and loading dock equipment without deformation or failure.
• Eliminates tripping hazards while providing safe, slip-resistant passage for pedestrians, wheelchairs, and rolling carts.
• Protects flooring edges (especially vinyl/tile transitions) from chipping, cracking, and wear from heavy equipment.
• Ensures code compliance on fire-rated door assemblies where heavy-duty, rated thresholds are required for life safety.
• Reduces maintenance costs with 10-year guaranteed construction that resists corrosion, humidity, and high-traffic wear.
• Improves safety in wet/humid areas with non-slip surfaces that maintain traction even when wet (hospital cafeterias, coastal facilities).

Applications

• Industrial facilities & manufacturing plants with forklift traffic, heavy equipment movement, and high load-bearing requirements.
• Warehouses & distribution centers where delivery doors experience constant pallet jack and truck loading/unloading.
• Hospitals & healthcare cafeterias with high foot traffic, housekeeping carts, and moisture-prone cleaning conditions.
• Schools & institutional buildings requiring durable, fire-rated thresholds in cafeterias, gyms, and main entrances.
• Coastal buildings & high-humidity facilities where corrosion-resistant aluminum prevents degradation from salt air or moisture.
• Tile-to-floor transitions protecting edges of 1/8" vinyl/tile flooring at commercial doorways.
