Neatdek 188 Decking

The Modular Decking Range

Neatdek 188 is developed from the original T-bar concept of our Neatdek system, adding an overlapping surface area to provide maximum privacy and prevent the passage of debris.

Our Modular Decking Solution

Our Neatdek 188 still incorporates the swage-locked construction but adding a parallelogram variation creates a concealed-gap surface with discreet free-flow drainage. Its unique profile completely restricts views from above and below for maximum privacy. It also restricts the passing of any solid objects to the surfaces below. Being A1 Fire Rated and fully compliant with BS EN 13501-1, our decking is available with a specially engineered anti-slip surface and can be coated in a range of standard RAL colours or even a bespoke durable colour coating of your choice to add to the aesthetic.

188’s Overlapping Surface

Due to the design of our Neatdek 188, the overlapping surface creates total privacy while keeping the free-flowing drainage, making this the most unique modular decking.

Fixing Detail

Our decking has a quick and easy system to install using our Easy Fixing Clips, with no drilling involved, this makes it a truly modular product to install.

Standard Colour Range

Our decking is manufactured in mill finish or can be powder-coated in a range of durable standard RAL colours. Neaco has its own in-house powder coating facilities which also allows us to provide any durable coated RAL colour of your choosing. The decking is put through our polyester powder-coating plant in our factory due to polyester being weather and UV-resistant, providing high colour stability.

Swage-Locked Construction

Our Neatdek 188 features our unique swage-locked construction which provides high structural efficiency. The system is lightweight (1/3 of the weight of steel) yet high in load-bearing capacity.


Aluminium is corrosion-resistant, so unlike other metals, it will stay rust-free. Its maintenance-free qualities give it a clear advantage over timber decking which gets damaged by weathering and temperature fluctuations. Aluminium has a design life of 60 – 100 years, making it perfect for projects where access to maintenance is restricted.

Eco Friendly

Aluminium is 100% recyclable with no downgrading of its properties and very little energy required for re-melting. It can be recycled over and over again without loss of performance – there is no difference in quality between virgin and recycled aluminium alloys. This can increase the BREEAM rating on a project.

Safe Underfoot

Neaco’s technical team has incorporated improved performance capabilities such as anti-slip surfaces into our Neatdek aluminium grating, which is now widely specified for balcony flooring. This particular Neatdek has no visible gaps due to the overlapping surface. It’s even safe to walk on in stilettos.


Aluminium’s fire resistance is superior to GRP, composite and timber decking. The latest guidance for residential buildings advises that combustible materials should not be used on buildings greater than 11 metres. The BS 476 Fire Test Series, achieves the highest possible rating for Non-Combustibility, Ignitibility, Fire Propagation and the Surface Spread of Flame Tests.

Why do we use Aluminium?
Aluminium is a great building material for many reasons: it provides maintenance-free durability and is non-toxic, corrosive-free, non-combustible and 100% recyclable. It's also lightweight yet strong, which makes Techdek an ideal specification for applications such as roof access walkways. Aluminium's aesthetically pleasing properties can be further enhanced with coating or anodisation.
What is a Modular System?
Modular systems provide a huge range of modular components which are precision manufactured off-site to an exacting standard, delivered to site, and then assembled on-site. This means factory-controlled quality, faster installation, less mess, less waste, and less energy consumption than product which are fabricated on-site.
Does Neaco Install as well as Supply?
Yes, we provide a full installation service in addition to technical support and consultation throughout the specification process. Our team of experts is always on hand to assist at every stage.
What are the acoustic properties of Aluminium Decking?
This answer has many factors so an accurate answer is difficult. It depends on the weather, what is hitting the decking, the force, the weight etc. The best answer we can give is that you request a sample for your own peace of mind.
Does the aluminium decking get hot?
Aluminium dissipates heat very well as it has a thermal conductivity value of around 235 Watts per Kelvin per meter so it will take longer to warm up after receiving heat such as direct sunlight. As a result, the surface and core temperatures cool much faster than with other metals.
What is the maximum span?
We offer Neatdek 188 in spans up to 1650mm
