Qwickbuild A120 Joist/Beam Profile (45 x 45 x 5800mm) Low Height

✅ Ultra-low height aluminium joist profile: just 13mm high

✅ Ideal for installations with tight height constraints such as rooftop decks, over waterproof membranes, and ground-level patios

✅ Engineered for use with a wide range of exterior finishes: composite decking, tiles, hardwood boards, and artificial turf

✅ Manufactured from structural-grade, anodised aluminium: lightweight, corrosion-resistant, and dimensionally stable

✅ Designed to integrate into the QwickBuild modular decking system for fast, accurate, and compliant construction

Load & Span Performance (Structural Data)
Maximum Joist Span (Single Span):
• Decking (composite/timber) 300–400mm (typical, centre-to-centre)
• Tile (on tile tray system) 300mm (centre-to-centre)

Note: These spans are conservative and based on typical residential live loads. Actual values should be confirmed via project-specific engineering or QwickBuild's design software.

Load Capacity (Indicative Figures):
• Uniformly Distributed Load (UDL): Up to 1.8 kN/m² (based on span < 400mm with support at recommended centres)
• Point Load (PL): Supports 1.4 kN concentrated point load over short span when supported at both ends

⚠️ Important: UDL and PL performance is dependent on full subframe design, finish type, support spacing, and installation method.

🔩 Compatible Components Used with A100 Profile

✅ Connectors & Fixings:
• A100 Joiners – Inline aluminium joiners for extending joists
• Stainless Self-Drill Screws – For secure fastening and corrosion resistance
• Tile Tray Clip Systems – For direct integration of tile finishes (QwickGrate™ or TileTrak™ system)

✅ Finishing Surfaces Compatible:
• Composite Decking Boards
• Porcelain or Stone Tiles (via tile trays)
• Timber Decking Boards

• Low-height balcony flooring systems
• Modular outdoor rooms or spa platforms

QwickBuild Aluminium Subframe – Materials & Care Guide

🔧 Material Overview
QwickBuild aluminium profiles are part of a modular, high-performance subframe system used to support decking, tiles, turf, and other outdoor surface materials. The system is designed as a durable, low-maintenance alternative to timber, particularly in environments exposed to moisture, UV, and temperature changes.

✅ Profile Composition:
• Material: Structural-grade aluminium alloy
• Finish: Anodised or powder-coated for corrosion resistance
• Common Profiles: A100 (13mm), A110 (28mm), A200, A250
• Accessories: Connectors, joiners, brackets, packers, and pedestals

🧰 Handling & Installation Care
• To maintain the structural integrity and appearance of QwickBuild profiles during installation:
• Cutting: Use a fine-tooth aluminium saw blade. Deburr cut edges to avoid sharpness or snagging.
• Drilling: Use appropriate drill bits for aluminium if custom hole positioning is required.
• Protective Film: Some profiles may arrive with a protective film—remove this only once cutting and installation are complete.
• Avoid Dissimilar Metals: Use only compatible stainless steel fasteners to prevent galvanic corrosion.
• Surface Protection: If installing over membranes or delicate substrates, use rubber pads or isolation strips to protect both surfaces.

🧼 Maintenance & Cleaning
• One of QwickBuild’s core benefits is its minimal maintenance requirement, but some occasional care is recommended:
• Routine Maintenance (Twice Annually):
Clear debris from between joists or around pedestals to maintain proper airflow and drainage.
• Rinse with clean water to remove dirt, dust, and any buildup of organic material.
• Check fixings and brackets are still secure, especially in high-traffic areas.
• Deep Cleaning (As Needed):
Use a mild pH-neutral detergent with warm water and a soft cloth or sponge.
• Avoid harsh solvents, acidic cleaners, or steel wool which can damage the anodised finish.
• For coastal or salt-exposed locations, rinse more frequently with fresh water to reduce corrosion potential.

🚫 What to Avoid
• No Pressure Washing directly onto bare profiles—this may drive debris into joints or dislodge components.
• Do Not Paint or Varnish the aluminium unless specified by the manufacturer—this may void warranties.
• Avoid Contact with Copper or Untreated Steel, as dissimilar metals may accelerate corrosion.
• Don’t Drag sharp tools or heavy loads across the surface finish, which may cause scratching.

🌿 Environmental Considerations
QwickBuild aluminium profiles are fully recyclable and offer a sustainable alternative to treated timber systems. The long service life and modular reusability of the system contribute to reduced lifecycle impact.

🔄 System Check-Up (Annual):
• Inspect connections, fasteners, and supports for movement or wear
• Confirm surface boards or tiles are secure and seated correctly
• Assess for any potential water pooling or blocked drainage

🛠️ Repair & Replacement
• Damaged Profiles: Can be removed and replaced individually if needed
• Component Replacement: Standard QwickBuild brackets and supports are modular and can be retrofitted without major dismantling
• Upgrades: The system supports refinishing with new decking or tile surfaces if future updates are desired

📞 Support & Warranty
QwickBuild profiles are backed by manufacturer warranties when installed according to system guidelines. For installation advice, technical data sheets, or replacement part requests, please contact your supplier or authorised QwickBuild partner.

❓ What is the QwickBuild system?
QwickBuild is a modular aluminium subframe system designed for the construction of low-height, moisture-resistant, and long-lasting outdoor surfaces such as decking, tiles, turf, and composite platforms. It replaces traditional timber subframes with a faster, straighter, and more durable solution.

❓ What are QwickBuild aluminium profiles made from?
QwickBuild profiles are made from structural-grade, anodised aluminium, which is lightweight, corrosion-resistant, and dimensionally stable. Unlike timber, aluminium won’t rot, twist, or warp, even in wet or coastal environments.

❓ Where can I use QwickBuild profiles?
QwickBuild profiles are suitable for a wide range of applications, including:
• Rooftop decks and balconies
• Over waterproof membranes
• Ground-level patios and slab overlays
• Raised platforms and pool surrounds
• Residential and commercial outdoor areas

❓ What profile heights are available?
QwickBuild profiles come in various heights to suit different project requirements:
• A100 – 13mm (ultra-low profile)
• A110 – 28mm (low/mid profile)
• A200 / A250 – Higher joists and bearers for increased span and elevation

Each profile is selected based on the available build height, loading requirements, and surface finish type.

❓ Can QwickBuild profiles be used under tiles as well as decking?
Yes! QwickBuild is one of the only systems that supports decking, structural tiles, and turf on the same aluminium subframe. Tiles are supported using specially designed tile trays or clip systems, ensuring proper weight distribution and drainage.

❓ Are QwickBuild profiles suitable for use over waterproof membranes?
Absolutely. QwickBuild aluminium joists are non-corrosive and allow for ventilation and drainage, making them ideal for installations over waterproofing systems on rooftops and balconies. Non-penetrative pad or pedestal systems are used to avoid damaging membranes.

❓ How do I connect and support QwickBuild profiles?
QwickBuild profiles use a range of compatible components for connection and support, including:
• Cross-joins, angle brackets, and joiners
• Fixed-height packers or adjustable pedestals
• Noggins and lateral bracing for structural integrity

❓ What surface materials can be installed on QwickBuild profiles?
• QwickBuild is compatible with:
• Composite decking boards
• Hardwood timber decking
• Structural exterior tiles (on tile trays)
• Synthetic turf systems

❓ How long are QwickBuild profiles?
Most QwickBuild profiles, such as the A100 and A110, come in 5800mm lengths as standard, though they can be cut to size on site or extended using inline joiners.

❓ Do QwickBuild aluminium profiles meet building standards?
Yes, QwickBuild profiles are designed to comply with building regulations for structural loading, fire safety, and moisture resistance when installed as per the system guidelines. Full technical specifications and span/load charts are available for engineers and designers.
