National Guard Products Heavy Duty Thresholds

Key Features

• 10,000 lb load capacity: tested per BHMA ANSI A156.21 Heavy Duty standards to withstand forklifts, pallet jacks, and heavy equipment without deformation.
• SIA slip-resistant finish: Slip Index Approved coating provides maximum traction in wet, humid, or oily conditions, reducing slip-and-fall risks.
• Reinforced aluminum construction: made from 6063-T5 aluminum alloy with extra-thick walls for long-term durability under extreme stress.
• Neoprene weather sealing: select models (like the 896HD) include a neoprene insert that compresses under the door bottom to block air, water, and dust infiltration.
• Multiple height/width options: ranges from 1/4" low-profile (forklift-friendly) to 1/2" high (standard heavy-duty saddle), with widths from 2" transition strips to 6" wide thresholds.
• Fluted or flat top surfaces: fluted tops channel water away and increase slip resistance; flat tops protect tile edges and provide smooth transitions.
• Fire-rated & ADA compliant: certified for use on labeled fire door assemblies and meets ADA Accessibility Guidelines with maximum 1/2" rise for wheelchair access.
• Standard commercial lengths: available in 36", 48", 72", and 96" lengths for single and double door applications, with custom cuts available.

Key Benefits

• Withstands vehicular traffic including forklifts, pallet jacks, and loading dockequipment without cracking, bending, or failing under heavy loads.
• Prevents dangerous slips and falls with SIA-certified skid-resistant surfaces that maintain traction even when wet (ideal for cafeterias, coastal facilities, and industrial kitchens).
• Protects flooring edges (especially vinyl, tile, and concrete transitions) from chipping, cracking, and wear caused by heavy equipment wheels.
• Ensures code compliance on fire-rated door assemblies where heavy-duty, rated thresholds are required for life safety and smoke control.
• Reduces long-term maintenance costs with durable aluminum construction that resists corrosion, humidity, salt air, and high-traffic wear for 10+ years.
• Improves energy efficiency by sealing air leaks at the doorway with neoprene inserts, lowering HVAC costs and preventing drafts.
• Accommodates ADA accessibility with low-profile designs that allow smooth wheelchair, cart, and walker passage without tripping hazards.

Popular NGP Heavy Duty Threshold Products

• NGP 8132-96 Heavy Duty Aluminum Transition Strip: The NGP 8132-96 is a 96" long × 2" wide × 1/8" tall aluminum transition strip designed to protect the edge of 1/8" vinyl tile at doorways. Made from 6063-T5 aluminum, it reduces tripping hazards and prevents tile chipping from foot traffic or light equipment. Ideal for commercial interiors where tile meets carpet or concrete, offering a smooth, durable transition.
• NGP 896HD SIA Heavy Duty Half Saddle-Threshold: The NGP 896HD SIA is a 5" wide × 1/2" high half saddle threshold featuring a neoprene insert for superior air and water sealing, plus an SIA slip-resistant finish. Tested to 10,000 lbs per BHMA ANSI A156.21, it's fire-rated, ADA compliant, and ideal for industrial facilities, schools, hospitals, and cafeterias where heavy traffic and moisture resistance are critical. Available in standard commercial lengths.
• NGP 613HD SIA Heavy Duty Threshold: The NGP 613HD SIA is a 6" wide × 1/4" high low-profile threshold with a fluted top and SIA slip-resistant finish, specifically designed for forklift and vehicular traffic. Passed 10,000 lb BHMA Heavy Duty testing, it's ideal for delivery/storage doorways, warehouses, and loading docks where heavier loads travel. The low 1/4" height minimizes tripping while accommodating forklift wheels without deformation. Available in 36", 48", 72", and 96" lengths.
