Berry Systems spiral barrier for
shopping centre.
Berry Systems designed a barrier that would not only protect the edges of the ramps but would also carry the lighting supports and some electrical cabling.
The new GBP200 million Centrale shopping centre in Croydon was built by Bovis Lend Lease for St Martins Property Investments Limited It features 800,000 square feet of shopping with some of the country's leading stores including House of Fraser and Debenhams

Contract for the safety barriers awarded to Berry Systems by Benjamin Armitage Construction, on behalf of the owners Wing Yip and Brothers Property and Investments .
The sloping nature of the site meant that the brand new 950 space shoppers' car park had to be fitted in around the retail areas and left a relatively small area in which to fit the access ramps.
Planning requirements meant that a towering central core would have had too much impact on neighbouring residential dwellings, so an intricate spiral design was developed that fitted into the contours of the site.
This brings vehicles up from ground level to a height of over 15m at the first parking level, situated above the three storey House of Fraser.

An adjacent exit spiral ramp takes vehicles back down.
Bovis contacted barrier specialists Berry Systems to design a barrier that would not only protect the edges of the ramps but would also carry the lighting supports and some electrical cabling.
It had to be manufactured to exactly match the geometry of the ramps which were not a consistent radius as they had to fit the slope of the site.
Using their Berry Beam system mounted on their patented spring steel buffers to form the basis of the safety barriers, they then added a handrail with mesh infill at 1100mm height on all the barrier on the internal radius of the spiral.
A removable solid steel plate was fitted below the barrier to block any water splash and this plate also doubled as cable protection for the lighting cables.
The entire system runs from ground level to the main access points on the 4th level, on both sides of the ramps.
A total of 800 metres.
Berry Systems Commercial Director Ian Darlington said "Spring steel buffers were an ideal choice for this installation".
"Because the ramps were mounted on a steel deck we had to make sure the barrier posts didn't breach the waterproofing".
"Spring Steel Buffers need a much shallower embedment than rigid posts as well as using fewer fixings".
"This helped us keep well above the waterproofing".
"We were also able to cope with manufacturing the barriers so that each section was curved to fit an exact location and so all the barrier sections were carefully numbered during manufacture and had to be assembled in precisely the right order on site".
"At times like these it's a great advantage having our own installation teams who are completely familiar with the system".
"There were no major problems and everything went together pretty smoothly".
Bovis Lend Lease have decided this spiral design is such an effective use of space they intend including it in a number of forthcoming projects.
