Threshold Ramps & Plates

Threshold Ramps & Plates

Threshold ramps and plates are critical architectural hardware components that provide a smooth, safe, and compliant transition between floor levels at doorways. Used to bridge height differences, provide sealing platforms, and support accessibility, these products play a vital role in meeting performance, safety, and regulatory standards in both commercial and residential applications. John Barnes Group proudly supplies a range of threshold ramps and plates from trusted brands including Kilargo, Lorient, and Raven—known for their durability, compliance with Australian Standards, and seamless integration with other door hardware.

Whether specified for aged care, retail, education, hospitality, or multi-residential developments, our threshold ramps and plates support safe movement through doorways while complementing acoustic, smoke, and fire sealing systems. Buy Threshold Ramps & Plates online today from the John Barnes online shop!

What Are Threshold Ramps & Plates?

Threshold ramps and plates are hardware profiles installed at the base of doorways to bridge gaps between floor levels or provide a platform for door seals. These components:

• Facilitate smooth access for wheeled mobility devices

• Improve air, sound, and water sealing performance

• Prevent tripping hazards at door thresholds

Typically made from extruded aluminium or stainless steel, these solutions are available in various profiles to suit different door types, environmental conditions, and compliance requirements.

Types of Threshold Ramps & Plates

Buy Threshold Plates online

Flat or gently ramped metal profiles that sit beneath the door and provide a sealing surface for drop seals or bottom door seals.

Use cases:

• Acoustic-rated doors

• Smoke and fire containment doors

• Air-tight and thermally controlled spaces

Beveled or sloped profiles that provide a smooth gradient over raised thresholds. Designed for accessibility and compliance with AS1428.1.

Use cases:

• Aged care and healthcare facilities

• Commercial buildings

• Apartment complexes and public buildings

Buy Stepped Threshold Plates online

Combine a flat plate with a minor upstand or step to match the level of adjacent flooring or accommodate door seal profiles.

Use cases:

• Fire doors

• Wet areas

• Industrial or plant room doors

Integrated systems that incorporate a plate with a drip groove, water dam, or thermal break to meet multiple performance requirements.

Use cases:

• External doors exposed to weather

• Commercial kitchens and labs

• Green star-rated buildings

Key Features and Specifications

• Material Options: Extruded aluminium (typically anodised), stainless steel, thermal break inserts

• Widths: Standard widths range from 50mm to 300mm; custom cut options available

• Heights: Designed to meet 0–20mm level differences; higher ramp systems available for specific applications

• Fixing Methods: Screw-fixed, adhesive-backed, or recessed installation

• Finishes: Clear anodised, bronze, black anodised, and powder-coated options

Australian Standards and Compliance

Threshold ramps and plates are essential for ensuring compliance with several Australian Standards:

• AS1428.1: Design for access and mobility – slope gradients, nosing, and slip resistance requirements

• AS1530.4: Fire resistance testing – compatibility with fire-rated door systems

• AS1530.7: Smoke leakage testing – sealing integrity

• AS/NZS 4586: Slip resistance classification of new pedestrian surface materials

• BCA/NCC: Compliance with minimum accessibility and safety requirements

Material Options and Performance

Aluminium (Anodised)

Lightweight, corrosion-resistant, and suitable for both internal and external use. Anodised finishes enhance durability and aesthetic integration.

Stainless Steel

Used in high-impact or corrosive environments such as industrial kitchens, marine zones, or chemical facilities.

Thermal Break Inserts

Enhance energy efficiency by reducing thermal conductivity through the threshold, ideal for energy-compliant and green buildings.

Applications: Residential vs Commercial

Residential Applications

In residential settings, threshold ramps and plates are used to ensure comfort and accessibility:

• Smooth transitions at entry doors

• Protection from water ingress on external doors

• Level changes between tiled, timber, or carpeted flooring

Ideal products include low-profile anodised aluminium plates or discreet threshold ramps that meet aesthetic and functional needs.

Commercial Applications

In commercial, institutional, and public buildings, threshold systems support a range of critical functions:

• Fire and smoke containment in corridors and stairwells

• Acoustic sealing in conference or healthcare environments

• Accessibility compliance at building entries

• Energy efficiency in climate-controlled spaces

Product Selection Guidance

For Architects and Designers

• Choose profiles that meet AS1428.1 slope and width requirements

• Select finishes that match the door and frame design

• Integrate with compatible drop seals and perimeter sealing systems

For Builders and Installers

• Confirm floor level differences before selecting ramp or plate height

• Ensure slip-resistant finishes in wet or high-traffic zones

• Select fixings appropriate to floor material (e.g., concrete, timber)

For Residential Clients

• Choose low-profile ramps to maintain aesthetics

• Install at external doors for improved sealing and weather protection

• Ensure smooth and safe access for prams, trolleys, or mobility devices

Installation Tips

• Use provided fixing points to secure into floor substrate

• Apply sealant around plate edges where water or dust exclusion is needed

• Ensure even, level installation for effective drop seal activation

• Clean surfaces before adhesive application (where applicable)

Maintenance and Care

• Regularly inspect for wear, corrosion, or loose fixings

• Clean with mild detergent and soft cloth or brush

• Check compatibility and operation with door seals during routine maintenance
