Double Your Floor Space
Without Relocating
Mezzanine floors are a cost-effective way to maximise your existing space by utilising unused vertical height — effectively doubling your usable floor area without the need to relocate or undertake major construction.

Mezzanine structures are semi-permanent and free-standing — installed within your existing space with minimal disruption. Their flexible design allows for reconfiguration and relocation as your business needs evolve.

Three Flooring Options
The right flooring depends on load requirements, operational use, ventilation needs and surface finish. Each system suits different applications.
Unilin Mezzanine Flooring Panels
Prefinished 38 mm particle board mezzanine flooring. Sturdy and effectively absorbs both distributed and point loads. Long-lasting, quality mezzanine floor solution. White underside enhances light reflection.
Meiser Mezzanine Grating
Galvanised press-locked steel grating featuring a sturdy open grid assembly. Designed to support heavy loads with minimal weight. Improves air circulation, reducing the need for mechanical ventilation.
ResinDek® Performance Engineered Flooring
Engineered to perform in the most demanding environments. Provides a smooth, level surface that supports the efficient movement of goods, vehicles and people. Ideal for high-traffic mezzanine applications.
Mezzanine Floor Weight Ratings
A mezzanine floor's weight capacity relies on the construction materials used. Standard structures typically support 400 kg/m² for light storage. Our structures can be custom-built to hold well in excess of this for heavy industrial applications.
Minimum total height of 4.2 m recommended — 1.9 m above mezzanine floor, 2 m below. Confirm with your structural engineer.
Mezzanine Accessories
Complete your mezzanine system with compliant access and safety accessories. All accessories are available in galvanised or powder coat finish.

Frequently Asked Questions
What is a mezzanine floor?
A mezzanine floor is a semi-permanent, free-standing structure installed within an existing space to create an intermediate level. Unlike conventional floors, mezzanines are not permanent fixtures — they can be reconfigured and relocated as your business needs change.
What load capacity do mezzanine floors support?
Standard mezzanine floors typically support 400 kg/m² for light storage. Our structures can be custom-built to hold well in excess of this — up to 1,000 kg/m² for heavy machinery and industrial applications. Load rating depends on construction materials and structural design.
What height clearance is required for a mezzanine?
A minimum total height of 4.2 m is recommended — with 1.9 m of clear space above the mezzanine floor and 2.0 m of clear space below. Floor thickness typically ranges from 15–30 cm depending on materials and load requirements.
What flooring options are available?
Three flooring systems are available: Unilin 38 mm particle board panels (light to medium storage, office), Meiser press-locked steel grating (heavy industrial, ventilation), and ResinDek® performance engineered flooring (forklift access, high-traffic). Each suits different load and operational requirements.
Are mezzanine floors WHS compliant?
Yes. Mezzanine systems are designed to be Work Health & Safety compliant. This includes compliant staircases to AS 1657, perimeter handrails, guardrails, and safety gates for goods transfer. Falls and dropped goods are key safety considerations — appropriate protective measures are included.
Can mezzanine floors be customised?
Yes. Custom mezzanine floors can be designed and manufactured to any size, load rating, flooring type and finish. If standard configurations don't suit your requirements, enquire with your specifications and our team will advise on the right solution.
