Our client was a catering firm that moved around England. They essentially have a portable kitchen with a seating area, and cater for events such as ‘October fest’. They’ve travelled all over England. Their fantastic bespoke catering units needed an equally fantastic bespoke staircase.
What’s portable, contained and useable? Definitely not a staircase, but that’s the brief our client gave us. The challenge wasn’t that they needed a steel staircase, we are ace at fabricating steel staircases. The real obstacle was their design brief. Our client needed a functioning staircase, that could be moved around as they went from county to county…simple right? There was a catch… the staircase must be in one piece. They did not want the hassle of dismantling and assembling the staircase every time they moved location, which is understandable, but it made our job a little more complicated. Challenge accepted! (Just imagine this said the way Harry shouted ‘Expecto patronum’).
The client gave us lemons and we made the best lemonade they had ever tasted…not to toot our horn or anything.
We designed and fabricated a ‘Mesh contained square spiral staircase’. Hold tight we’re going to get technical.
We used container casings and inter-connectors to lock and secure our steel box sections, this allowed us to lock our large structural frame in place.
Durbar tread placeholders were welded to the steel central column, this created the desired spiral effect. We then added Durbar treads. These were cut into 4 different shapes, and welded on, in an alternating pattern (Simply so the treads fit correctly within the space available, with enough depth for foot placement).
We then enclosed the whole staircase with a surrounding mesh panel, resulting in a caged prism effect.
The whole structure was galvanised, and also fitted with a connection point so a crane could easily pick it up and move it elsewhere.
Just what the client ordered.
The polyhouse frame is made from galvanised steel. Galvanised steel provides long-lasting structural support due to its high strength and anti-corrosion properties.
The polyhouse cover (walls and roof) is constructed of GRP rooflights (Glass reinforced panels) instead of polyethylene sheets. These panels provide robust strength against high winds and hailstones; whilst still allowing natural light in. The panels are coated in a gel that protects against the effects of harmful UV rays, and they are even available in a selection of fire ratings.
It is safe to say that our polyhouses offer more strength and longevity than a traditional polyhouse, polytunnel or greenhouse.
So now, they have a kitchen that tours across England, and a strong, compact staircase that accompanies it. The perfect duo.
