Bespoke polystyrene rock sculptures and realistic rust-effect props from the early 1990s.
Looking back through some of Graham Sweet’s original photograph albums, we came across these wonderful images of a project we produced for Harrods window displays in the early 1990s.
The display featured a collection of artificial sandstone rocks, alongside our lightweight Rustlite hoists and chains, creating the appearance of heavy, weathered industrial materials.
Artificial Sandstone Rocks
The rocks were individually carved from expanded polystyrene (EPS) to recreate the irregular shapes, layered surfaces and natural textures of sandstone.
Each piece was then hand-finished with a realistic sandstone effect, giving the appearance of solid natural rock while remaining considerably lighter and easier to handle.
The lightweight construction made the rocks particularly well suited to window displays, where transporting, positioning and arranging large scenic pieces can otherwise be challenging.
Rustlite Hoists & Chains
Alongside the sandstone rocks, the Harrods displays also featured our Rustlite hoists and chains.
These were manufactured from polystyrene and finished to recreate the appearance of heavily rusted metal, complete with aged surfaces and weathered textures.
Despite their convincing industrial appearance, the props were lightweight decorative pieces rather than heavy metal components.
Combined with the sandstone rocks, they helped create a distinctive display using materials that looked far heavier than they actually were.
A Little Piece of GSS History
These photographs are a lovely reminder of the work Graham Sweet was producing more than three decades ago.
Although our workshop, equipment and production methods have evolved considerably since the early 1990s, creating convincing imitations of natural and industrial materials remains an important part of what we do today.
From realistic rocks and oversized boulders to stone-effect panels and bespoke scenic sculptures, we continue to manufacture lightweight props for retail displays, exhibitions, events, photography and television productions.
It’s wonderful to be able to revisit some of these earlier projects and share a little of our studio’s history.
