Threshold Ramps & Plates

Threshold ramps and plates are a simple, smart way to smooth out level changes at doorways, reduce trip hazards, and make access easier for everyone. Whether you’re updating a family home, fitting out a commercial tenancy, or working on a large-scale project, quality threshold solutions are essential to safe, compliant and comfortable access. At John Barnes Group, we make it easy to buy threshold ramps and plates online, with options to suit front doors, internal openings and external doorways across Brisbane, Queensland, New South Wales and Australia-wide.

Make Every Entry Safer and More Accessible

What Are Threshold Ramps & Plates?

Threshold ramps and plates are low-profile components installed at doorways to bridge the step or gap between different floor surfaces. They help create a smoother transition where tiles meet carpet, where internal floors meet balconies, or where an external landing meets the entry door. Combined with quality architectural door hardware, they play a major role in how accessible and user-friendly a space feels for occupants and visitors.

Safer Movement for Everyone

A well-chosen threshold ramp or plate makes walking through a doorway feel natural and secure. By reducing abrupt steps, they lower the risk of trips and falls for people of all ages. They’re especially helpful for prams, trolleys and luggage, and when coordinated with other access solutions they support wheelchair and mobility device users as part of a broader accessibility strategy.

Ideal for Residential and Commercial Projects

From modern townhouses and apartments through to busy retail tenancies, healthcare facilities and education spaces, threshold ramps and plates have a place in almost every project. In homes, they help make front doors, balcony sliders and internal transitions safer and more comfortable. In commercial and public buildings, they support higher foot traffic and more demanding conditions, helping to protect floor edges while keeping access smooth and professional.

Applications Across Your Property

Front Door and External Doorways

Front doors and main entries are where first impressions count. A well-fitted threshold plate can improve weather protection, minimise drafts and water ingress, and provide a clean, defined finish under your door. For external doorways, ramps help navigate small steps created by slabs, tiles or decking, supporting safe access from outside to inside and back again. Paired with premium front door hardware from brands like Lockwood and Zanda, your entry can look contemporary while still being practical and user-friendly.

Balconies, Patios and Sliding Doors

Balcony and patio doors often involve tracks, sills and slight changes in level that can create awkward bumps. Threshold ramps and plates help smooth these transitions without compromising drainage or performance. When you’re designing a modern, indoor–outdoor lifestyle space in Brisbane, Queensland, New South Wales or beyond, these small details make everyday living more seamless.

Internal Transitions Between Floor Finishes

Where carpet meets tiles, vinyl meets timber, or different floor heights occur, threshold plates provide a neat and practical finish. They protect vulnerable edges from damage and help create a continuous, professional look across internal spaces. In offices and commercial corridors, this can also help trolleys and equipment move more efficiently from room to room.

High-Traffic Commercial Zones

Entrances to shopping centres, office lobbies, healthcare facilities and other busy environments demand durable threshold solutions. The right ramp or plate helps manage the wear and tear that comes with high traffic, while supporting safe, intuitive movement. When combined with commercial-grade architectural door hardware from leading brands such as Dormakaba and Lockwood, you get a fully coordinated solution that’s built to perform.

Key Features of Our Threshold Ramps & Plates

Durable Construction for Australian Conditions

Threshold ramps and plates are typically manufactured from robust materials designed to cope with years of use. Common options include aluminium and stainless steel, chosen for their strength, corrosion resistance and clean, modern appearance. This makes them well suited to harsh Australian conditions, including coastal and humid environments around Brisbane and Queensland, as well as cooler regions of New South Wales and the rest of Australia.

Modern Finishes to Match Your Architectural Hardware

Threshold components play an important visual role too. A sleek threshold plate can complement your levers, pulls and locks, creating a cohesive look from floor to handle. Depending on the product selected, you’ll often find finishes that work beautifully alongside architectural door hardware in matte black, stainless steel, satin chrome or brass tones. That means you can pair your thresholds with premium handle and lock collections from brands like Barben, Zanda, Lockwood and Dormakaba for a consistent, modern or contemporary aesthetic.

Low-Profile, User-Friendly Design

A good threshold ramp or plate does its job without drawing attention. Low-profile designs help reduce visual clutter and allow easy movement through the doorway. When properly selected and installed, they can support safer access for both pedestrians and wheeled devices while still maintaining a slim, architectural look that aligns with the rest of your door hardware package.

Simple Installation and Retrofit Options

Threshold ramps and plates are generally designed with practical installation in mind. Many options are suitable for retrofitting to existing doorways, which is ideal when you’re upgrading older homes or commercial spaces to improve accessibility or update aesthetics. In new builds and major refurbishments, they can be integrated into the design from the outset, helping architects and builders create clean, functional transitions from day one.

Suitable for Residential and Commercial Use

Whether you’re updating a single front door in a Brisbane home or coordinating architectural door hardware across a multi-level commercial project, there are threshold solutions to match. Many products are suitable for both residential and commercial applications, giving specifiers the flexibility to maintain a consistent look and performance level across diverse areas within the same development.

Frequently Asked Questions

What is the main purpose of a threshold ramp or plate?

A threshold ramp or plate is designed to smooth out the level change between two floor surfaces at a doorway. It reduces trip hazards, protects floor edges and helps people, prams, trolleys and other wheeled devices move more easily through the opening. When chosen correctly, it also adds a neat, professional finish to your doorway.

Are threshold ramps suitable for wheelchairs and mobility devices?

Many threshold ramps can form part of an accessibility solution for wheelchairs and mobility devices, especially where small level changes need to be managed. However, every situation is different. It’s important to consider the overall access design, gradients and any relevant building or accessibility requirements for your project. Threshold ramps are often used alongside other access products to support safer, more inclusive movement.

Can threshold plates be used on both internal and external doors?

Yes, there are threshold plates designed for both internal and external openings. External options are typically engineered to deal with weather exposure, including rain and temperature changes, while internal versions focus on providing a neat, durable transition between indoor floor surfaces. When selecting a product, always check its suitability for internal, external or both types of applications.

What finishes are available to match my door hardware?

Depending on the specific product range, you’ll often find finishes that pair well with popular architectural door hardware. Common choices include natural aluminium, stainless steel, as well as finishes that coordinate with matte black, satin chrome or brass-toned levers, pulls and locks. This allows you to match your threshold components with complementary hardware from brands like Barben, Zanda, Lockwood and Dormakaba for a cohesive look.

Do I need a professional to install threshold ramps and plates?

Some simpler threshold ramps and plates can be installed by experienced DIYers, particularly in residential settings. However, for commercial projects, complex openings or where accessibility and performance are critical, it’s usually best to engage a qualified installer or builder. Correct measurement, fitting and fixing are essential to ensure the threshold performs as intended and integrates properly with your door and frame.

How do I choose the right size threshold ramp or plate?

Start by measuring the height difference between the two floor surfaces and the width of the doorway or opening. You’ll want a ramp or plate that covers the full width of the opening and provides a suitable transition across the step or gap. If you’re unsure, it can be helpful to provide your measurements to the John Barnes Group team so we can suggest options that suit your application.

Are these products suitable for high-traffic commercial environments?

Yes, many threshold ramps and plates are specifically designed to handle frequent use in commercial and public spaces. Materials like aluminium and stainless steel are commonly used to deliver strength and durability in busy entrances, corridors and shared areas. When selecting a product for high-traffic zones, look for robust construction and a profile suited to the expected use of the doorway.
