NeoLine Decking Subframe
Low-profile sleepers. Adjustable pedestals and aluminum joists. A modern, modular foundation for balconies, rooftops, terraces and patios.
A better foundation
NeoLine combines aluminum framing with purpose-designed supports and connections to simplify construction. Choose the system around the surface you are building on, the height available and the finished deck you want.
01LOW-PROFILE FOUNDATION
A slim aluminum foundation over a suitable solid surface. A considered choice for overlays, balconies and spaces with limited clearance.
02ADJUSTABLE FOUNDATION
Height-adjustable pedestals and lightweight aluminum joists create room to level the deck and manage the space beneath.
The work beneath the finish
Lightweight components, modular connections and rot-resistant materials make the foundation easier to assemble and adapt. The result is a practical system designed for lasting outdoor use.
50%
NeoLine’s modular pedestal-and-joist system reduces on-site measuring, cutting and assembly work.
Lightweight aluminum joists and pre-engineered connections simplify positioning and frame assembly.
Aluminum framing and durable plastic supports resist decay and are designed for outdoor moisture exposure.
Components can be dismantled and reused in suitable future layouts, helping reduce unnecessary replacement.
01 / NeoLine Sleeper System
Two aluminum sleeper profiles. Two matched clip systems. Choose AL02 with MC03 clips for the Essential Collection, or the ultra-low AL06 with MC05 for ZeroGap decking, to suit your boards and available height.
REGULAR DECKING
A 1″ aluminum sleeper paired with compatible MC03 concealed clips for NeoLine Essential decking.
ULTRA-LOW PROFILE
A ¼″ aluminum sleeper paired with the compatible MC05 twist-and-click fastener for NeoLine ZeroGap decking.
Both systems suit appropriate concrete, paved or membrane-protected surfaces. Plan the matching clips, protection layers, drainage and door clearances as one complete assembly.
UNDERSTAND THE HEIGHT
ESSENTIAL COLLECTION
ZEROGAP COLLECTION
Board and sleeper heights give a nominal starting point. Add the specified clips, protection pads and installation allowances when confirming the finished deck height and threshold clearances.
BALCONIES & ROOF TERRACES
A low-profile option for solid, membrane-protected surfaces where available height is limited. Use the approved protection and restraint details.
CONCRETE & PAVED PATIOS
Overlay a suitable, stable slab or paved area. Confirm its condition, support and drainage before planning the frame.
COURTYARDS & LOW DECKS
Create a slim deck above a prepared solid base, with clear routes for water to reach the existing drains.
02 / NeoLine Pedestal-and-Joist System
Choose the aluminum joist system that matches your decking collection. Adjustable pedestals help set the deck level over suitable sloped or uneven supporting surfaces while preserving drainage and room beneath the boards.
01 / REGULAR DECKING
Aluminum joist system for regular decking boards in the Essential and Woodland ASA Collections.
02 / ZEROGAP DECKING
Dedicated aluminum joist system for ZeroGap Collection decking boards.
PEDESTAL BODY HEIGHTS
Choose the model that fits the required support height.
Inch values are approximate conversions rounded to two decimal places. Range spans multiple pedestal models. Add the selected joist, board and protection-layer depths to calculate finished deck height.
High-strength plastic pedestals use a twist adjustment for precise positioning. Select the appropriate model for each planned support height.
Compatible slope adaptors help the supports suit pitched or uneven substrates. Match the adaptor, protection layer and bearing surface to the project.
Lightweight joists and modular connectors form the framework with less cutting and complex timber framing. Use the matching cradles and fixings.
A raised frame can make room for drainage routes and services. With a compatible removable-board system, planned access points stay easier to reach.
ROOFTOPS & PODIUMS
Adjust the walking surface while respecting the roof’s drainage slope, membrane protection and project-specific support layout.
TERRACES & SHARED AMENITIES
Plan elevated terraces, hospitality patios and communal spaces with loads, support spacing and restraint designed for the intended use.
SERVICE VOIDS & COMPLEX SITES
Create an organised cavity for permitted services. Ground-level sites still need suitable bearing, drainage and a foundation plan.
Quick selection guide
The right choice comes down to clearance, the supporting surface and how much adjustment you need. Compare the two systems, then confirm the complete layout with NeoLine and your installer.

| Project feature | LOW-PROFILESleeper System | ADJUSTABLEPedestal-and-Joist |
|---|---|---|
| Clearance | Low-profile layouts for limited height. The ultra-low option starts with a nominal ¼″ sleeper. | Adjustable support height across the 1.02–29.13 inches pedestal range, plus joists and boards. |
| Supporting surface | A suitable, stable solid surface such as a slab or membrane-protected patio. | A suitable load-bearing substrate with the planned pedestal bases and protection layers. |
| Slope & levelling | Best suited to flat or gently, uniformly sloped supporting surfaces. | Height adjustment and compatible slope adaptors offer more levelling flexibility. |
| Typical applications | Balconies, slab overlays, low-clearance patios and courtyard upgrades. | Sloped roofs, podiums, raised terraces and projects needing a service cavity. |
| Membranes & fixings | A floating layout may avoid membrane penetrations where approved for the project. | Pedestal bases and the frame are planned with membrane protection and required restraint. |
| Access underneath | A compact void with drainage paths planned around the low assembly. | More space for permitted services and planned inspection or maintenance access. |

From height allowances to membrane protection, these answers help you plan the details beneath your deck.
Start with the supporting surface and finished deck height. Sleepers suit compact layouts over suitable solid surfaces. Pedestals and aluminum joists offer more adjustment over sloped substrates and more room beneath the deck. Use the comparison above as a starting point, then confirm the site-specific layout.
The 1″ AL02 sleeper plus a 0.87″ Essential board gives a nominal board-and-sleeper height of 1.87″. The ¼″ AL06 sleeper plus a 0.87″ ZeroGap board gives 1.12″. Add the selected clips, protection pads and installation allowances when confirming the complete finished height and door clearances.
No. Those figures describe pedestal body heights across multiple models. The finished deck height also includes the selected joist, board and any required protective or levelling layers.
A floating layout may be suitable over an approved membrane with appropriate protection. Confirm compatibility with the membrane provider and the project’s drainage and restraint requirements. Non-penetrating installation does not remove the need to address wind or lateral movement.
Supports need a suitable load-bearing base. Soil, frost movement, drainage and bearing conditions must be considered in the foundation design. Pedestals do not automatically remove the need for foundations, ground preparation or site-specific support details.
The frame and support layout should leave continuous paths to the existing drains and allow inspection and cleaning. Coordinate sleeper orientation, protection layers and support locations with the drainage design; a low-profile frame does not itself guarantee free drainage.
A pedestal-and-joist layout can create space for permitted services and inspection access. ZeroGap supports individual board removal when installed with its matching fastening system. Plan service routes and access locations before installing the surface.
Aluminum does not suffer timber rot. It still needs compatible materials and fasteners, appropriate drainage, and a finish suitable for the exposure conditions. Allow for thermal movement according to the installation details.
It can be considered for these applications with a project-specific design. Confirm the load, spans, support spacing, restraint, roof capacity and applicable fire requirements for the complete assembly. An aluminum component alone does not establish a fire classification for the whole deck.
The modular system can be dismantled and components reused where their condition and compatibility suit the new layout. Inspect parts and confirm the revised support design before reinstallation.
Request the current written warranty for the exact subframe components and intended residential or commercial use. Confirm the terms, exclusions and installation requirements; decking-board warranty coverage should not be assumed to cover every support component.
