Stone-Countertop Trade Terminology
SF - Square feet, = length x width (depth to the wall), measured in inches, then divided by 144 = SF.
LF - Linear foot/feet. Also called RF or running feet. Distance in a straight line as opposed to SF.
Template - A final measurement of cabinets, sometimes using paper or foam/wood strips, to create a counter-cutting layout.
Fab - Fabrication is the labor to transport stone slabs, template patterns, cut to size, grind edge profiles, cut holes, polish and seal.
Quarry - a deep excavation to get raw-stone materials to the surface.
Dimension Stone - Stone quarried into blocks for an end-use, such as stone-countertop slabs.
Slabs - Flat pieces of natural or synthetic stone, quarried or molded to about 100-140" wide and 60-82" in height (depth).
Granite - A hard, natural, igneous rock, made of quartz, mica, and feldspar, and quarried from mountains all around the world.
Quartz - Man-made material of natural quartz (silicon dioxide) particles and polymer resin, baked under very high pressure.
Quartzite - Begins as sandstone, and becomes a metamorphic rock, baked by tectonic heat and pressure within the earth’s crust.
Marble - A natural limestone, crystalized as calcite and dolomite. Much softer than many other natural-stone materials.
Soapstone - Natural stone with a high talc content. Fractures easily, and needs frequent oiling to maintain its look and color.
Sandstone - Natural stone about equal in hardness to granite. Very porous. Specialized sealants. Not seen in most stoneyards.
Honed, Brushed or Leathered - Slabs are normally polished to be shiny. Honed = matte, brushed = bumpy, leathered = even bumpier.
Mohs Scale - 1-10 hardness scale created by Friedrich Mohs in 1822. Diamonds 10, granite and quartzite 8, quartz 7-8, marble 4.
Engineered - Synthetically created countertop materials, as opposed to those in nature.
Laminate - Thin, color-patterned plastic, veneered to layers of pressed-board. The most common laminate-counter name is Formica.
Solid Surface - Resin-based counters; can look like stone. Common names are Corian, Wilsonart, and Swanstone.
3 CM - Three centimeters of slab thickness = 1.2", often called "inch and a quarter". Best choice for stone countertops in kitchens.
2 CM - Two centimeter slab thickness = .8", or "three-quarter inch". Good for vanities, etc.. Slightly cheaper than 3 CM.
1.2 CM - 1/2" synthetic marble or quartz used to line showers, cover walls, or where strength and thickness is less important.
Rodding - Insertion of tubular rods (often stainless or fiberglass), sometimes used to strengthen certain areas of a countertop.
Edging - A profiled counter-edge, created with various shapes of diamond grinding-bits.
Corbels - L-shaped or flat brackets mounted under 8"+ counter overhangs, to reinforce them and help avoid stress cracking.
Granite backsplashes - Short (4"?) stone risers, rear of counters, usually done on vanities, but now only rarely in kitchens (Do tile!).
Drop-In - Sink mounted into a counter from the top, with a flange all around that covers the edges of a rough-cut hole.
Undermount - Sink installed beneath the counter, bonded in place, with a finished-stone edge that overlaps 1/4" into the bowl(s).
Bonding - The installation of undermount sinks & double edges with high-strength epoxy mixes.
Sink-Setters - Brace-brackets used to add more strength to an undermount kitchen sink.
Vessel - A sink which sits entirely on top of the counter. The top is not hole-cut, just drilled for the faucet and the drain hole.
Polishing - A process of wet micro-sanding with grades of abrasive to create a smooth, shiny surface.
Seal - Apply a chemical counter-sealant to increase spill resistance.
Remnants - Slab pieces left over after fabrication. Also called fall-off. Larger (+2x2 ft?) are usually saved by Fabricators.
Cuts - Slices cut with diamond blades and bits to create counters, or to "mount" sinks, etc..
Tooling - The use of cutters, grinders, polishers, etc. to fabricate raw-stone slabs into finished countertops.
Fab Table - A big, often tilting ("tilt-table"), reinforced-steel platform to cut & fabricate slabs.
Bridge Saw - A large overhead saw with a circular diamond-blade, used to make first cuts that shape a slab into counters.
Rail Saw - A smaller type of granite saw, also used for slab cutting.
CNC - Computer Numerical Control. An automated-cut version of a large bridge saw.
Dolly - A rolling cart with pads and clamps, used to move stone counters from an A-frame trailer into a home or a business.
Shims - Composite or cedar wedges to level variations in the top edges of cabinets.
A-Frame - An A-shaped frame, mounted on a trailer or truck, and used to transport stone counters.
We hope this helps you to learn about the stone-counter trade. We try to educate; so you can choose the perfect slab material, color, and pattern; plus the right sinks, edging, etc. - It's good to know the buzz words!
