Taking car parks to the next level

Kingspan uses Magnelis® to create corrosion-resistant decks for multi-storey parking structures

Demand for convenient car parking is rising dramatically. However, the land available for parking is severely limited in many locations. That’s making multi-storey car parks a very attractive option in city centres, near transport hubs, and at public buildings such as hospitals. To meet this demand in a cost-effective way, Kingspan, a leading building materials company, has developed a complete portfolio of solutions for car park builders. A key element is Magnelis® from ArcelorMittal Europe – Flat Products which Kingspan uses to form the deck of each level in the car park. As well as cost-effective forming and quick assembly, Magnelis® offers long-term protection against corrosion to ensure the safety and viability of parking structures.

Multi-storey car parks offer unique challenges for their owners. As well as providing safe and welcoming spaces for potential customers, they must withstand weathering from the elements – and the effect of de-icing salts and other chemicals which are tracked into the structure.

A complex product requires Magnelis®

To address these concerns, Kingspan has developed a multideck floor system based on Magnelis®. The system is quick to produce, lighter than alternative solutions, and simple to assemble on-site. “We create the deck panels by roll-forming the steel in our factory,” explains Phil Smith, Kingspan’s Managing Director for the UK and Ireland. “It is a complex product – the deck panels need to include cut-outs to ensure the concrete adheres to the steel. But Magnelis® is easy to form.”

10-year guarantee a major advantage

A key advantage of Magnelis® for Kingspan is the guarantee ArcelorMittal can provide on request. Phil Smith explains: “By using Magnelis® we can offer a 10-year guarantee on our decks. That can be extended up to 20 years depending on the location of the car park and the thickness of the Magnelis® coating.”

Kingspan utilises ArcelorMittal’s technical support at all stages of the project. “We are quite often involved in projects where the environment is aggressive such as swimming pools, car parks, and installations which generate energy from waste,” says Phil Smith. “In these projects we involve ArcelorMittal during the design phase to ensure we are selecting the right materials.”

Sustainability at every step

Kingspan offers a complete range of solutions for multi-storey car parks including the Magnelis® composite decks explains Phil Smith: “We also have barrier protection systems, perforated facades, and solar panels for the top floor so the car park can generate energy for lighting, ventilation, and electric vehicle charging points. Our goal is to create sustainable solutions at every stage. And steel is our material of choice to reach this goal.”
