stone fabricator
A company which cuts and sells ornamental stone pieces used in a structure, either inside or as a supplement to the facade.
Companies which produce and supply stone panels and pieces for major interior work or for a small part of the facade. If the facade is mostly stone then the company would be classified as a facade supplier.
The product is worked stone supplied as panels or individual pieces. Its architectural use can be inside the building or in a limited part of the exterior, as distinguished from supplying a facade that is mostly stone.
A facade fabricator is distinguished here by the extent of stone use across the exterior. A paving block manufacturer supplies blocks for outdoor paving, a different application from the interior work and facade pieces described above.
