Creating a durable and efficient car park is a vital component of modern urban development. With the right materials and innovative designs, a car park can be both functional and visually appealing.

This blog post will guide you through choosing the best car park decking materials, exploring innovative multi-storey car park designs, understanding waterproofing and coating solutions, and enhancing safety and cleanliness to achieve the perfect car park.

Choosing the Right Car Park Decking Material

Selecting the right car park decking material is crucial for the success of your project. The choice of material can greatly impact the overall durability and maintenance requirements of your car park. Some of the widely used materials include composite car park decks, steel frames, and metal floors.

Each material has its own set of advantages and drawbacks. For instance, steel frame and composite concrete flooring are known for their durability and low maintenance requirements, but they may be more expensive than other materials. On the other hand, PUMA, PU, and PU Concrete offer more affordability, but they are not as resilient and require more upkeep.

Therefore, it is essential to carefully weigh the pros and cons of each material before making a decision.

Steel frames are an excellent choice for car park construction, offering rapid construction, large free spans, and customisable layouts. Kingspan’s Multideck steel decking products are constructed with galvanised steel and provide several benefits for car park construction.

The coating used in Kingspan XP steel is ArcelorMittal Magnelis coating, which comprises 3.5% aluminium and 3% magnesium.

The warranty duration for Kingspan steel decking systems is contingent upon the car park environment and the product specification.

Raised Floor Solutions can provide a full supply and installation package based on the Kingspan system specified and the environmental location of the build.

This will ensure a system warranty and guarantee at the design and construction stages of the work.

RFS maintains Professional Indemnity Insurance of up to £5M. This includes protection for both workmanship and materials.

Metal Floor

Metal floor car park decking, made from materials such as steel or aluminium, is commonly used in car parks and other outdoor areas due to its strength and fire resistance.

The advantages of metal floor car park decking include high durability, uniform quality, excellent fire resistance, and design versatility.

However, the primary disadvantage is that it can be slippery when wet and noisy when traversed, and is more costly than other decking materials.

Kingspan Multideck MD60 and MD80 are popular metal floor decking types in the UK. They are the most commonly specified within the industry.

MD80 offers a deeper profile, allowing for spans of up to 5.4m unpropped. Steel decking products typically require more concrete than other materials. However, its special profile requires less to achieve the same slab thickness.
