Structural Roof Deck Case Study : Morrisons Openshaw

January 6, 2011

Morrisons Openshaw Case Study
Following years of planning, South Yorkshire-based Dransfield Properties has embarked on what represents East Manchester’s biggest private investment for some time, in the form of the new Lime Square retail development, off Ashton Old Road in Higher Openshaw.

Located on an 11.9 acre site, the £40 million development creates a much needed new commercial heart in the area it serves. It is a powerful symbol of the renaissance that is taking place in Openshaw, providing a family-focused neighbourhood that benefits residents and encourages relocation and investment.

The first phase of the project, a new 80,000 sq.ft. Morrisons store and 670 car parking spaces, was opened on schedule in the autumn of 2010. It is the first new opening in the country with an in-store Peacocks outlet – the fashion retailer has taken 6,000 sq ft following a deal announced between the two companies earlier in 2010.

D60 Roof Deck - Morrisons OpenshawThe store features Morrison’s very well established standard built-up roof specification featuring 9,000m2 of the D60 structural roof decking system, installed by QM Roofing Ltd of Dewsbury, Yorkshire.

D60 Structural Metal Roof Decking is a popular choice amongst both structural engineers and architects, particularly in supporting single-ply roofing applications. Capable of spans up to 4500mm, D60 features an 800mm cover width and a 200mm pitch that provides a very strong deck and offers excellent insulation support. An open width of just 110mm eliminates the risk of insulation dip or breakage.

Single Ply Roof on D60D60′s lightweight construction also minimises the load on the building structure. Brian Baldwin, a director of QM Roofing, outlined the roof construction at Morrisons, Lime Square: “We have been installing roofs on Morrisons’ supermarkets for over 20 years. We work to the company’s standard built-up roof specification that is tried and tested and has essentially remained unaltered for over a quarter of a century.

“We find D60 to be very easy to install and have never had any problems with deliveries. These key benefits played a vital role in the completion of the entire roof in ten weeks, making an important contribution to the on-schedule opening of the store.”

Sure enough, the store was officially opened precisely on time by Sir Ken Morrison and Sir Ian Gibson, of Morrisons, watched by members of the Morrisons board and an eager crowd of waiting shoppers.

Dead Blow Sculpture at Morrisons OpenshawAfter the store opening Sir Ian Gibson, who was born and spent his early school years in Openshaw, was invited to officially dedicate a new steam hammer sculpture commissioned for the development.

Called Dead Blow the £175,000 piece of public art stands 29 ft. high and was created by the award winning sculptor Robert Erskine to reflect the industrial history of the area – it is designed to be part of the main pedestrian walkway on to the centre.

Sustainable application of metal decking

August 18, 2010

As a 100% recyclable product, metal roof decking is the ideal choice when sustainability in construction is a key consideration. However, there are a number of other benefits to using metal decking in the construction of single-ply, standing seam or green roofs.


It’s incredibly strong for its weight, the fact that metal decking can span up to 12 metres allows building designers to lose much of the secondary structure.  Roof deck is fast to lay therefore reducing time on site and as large quantities can be bundled and loaded effectively, each lorry delivers a vast roof area, reducing the number of vehicles to site, not to mention all associated traffic, unloading and storage activities.  Roof deck  is a solution to the negative environmental impacts of a construction site – reducing noise, emissions, traffic congestion and more importantly our carbon footprint.

Energy use

Adams Brewery, Green roof solution with Corus D159These substantial sustainability benefits pale into insignificance, compared to the benefits gained over the life of a building, by utilising metal deck sustainable roof design. It is commonly accepted that the embodied energy in a building is approximately one tenth of the energy used in that building over a period of 50 years. The impact of including a highly insulated, well sealed metal deck roof can be a reduction in heat loss through the roof by half.

Green Roofs

Adnams Brewery using D159 DeckHowever it’s not just about carbon and energy, metal deck green roofs offer far more than just that.

  • Slows the run off. They reduce the amount of rain that runs off the roof and they slow down the peak rate of runoff by several hours, which in turn dramatically reduces flooding and the burden on the drainage system. The water is cleaned as it percolates through the layers.
  • Habitat for wildlife. They cool the surrounding air as well as the building they are on and they provide a safe habitat for plants, bees, butterflies insects and birds.
  • Feel good factor.  Green roofs look good in any work or home environment and encourage wildlife.
  • Economics. Green roofs reduce the need for air conditioning and heating so they save money.
  • Planning benefits. Many councils now insist on the inclusion of green roofs in building developments.

As a recent example, the UK’s largest and greenest sustainable storage facility at Adnams Brewery used a metal deck green roof with a Corus Panels and Profiles D159 under a Sky-Garden Greenroof to reduce the visual impact of the building on the landscape and to regulate the internal temperature. A drip irrigation system was installed to sustain the plants.
