Bespoke GRP housings
Made to your dimensions when a standard size will not do
Every project is different. When our standard cabinets and walk-ins are close but not quite right, we manufacture a GRP housing to your exact requirements in our own workshop in Wales. Send us a drawing, a sketch, or a clear list of sizes, and we will tell you straight what we can build.
One workshop, one point of contact
Celtic Composites Ltd offers made-to-measure GRP housing solutions so your project is not forced into a size that does not fit. Forty years in the trade means we have seen most of the common outdoor housing problems before, and we know how to turn a practical brief into a unit that keeps expensive equipment safe and dry.
We are a small, family-run manufacturer. That is the point. You deal with one person, we control the whole build in-house, and we take on work we can do properly. If a job is too large or the wrong type for us, we will say so early.
