3 Production Sites in Guangdong, China · 10,000+ m² Slabs in Ready Stock · Factory-Direct Export
We are a stone factory in China with our fabrication line in Yunfu. Send a drawing or a cabinet layout and we return finished quartz kitchen countertops, or tops in granite, marble, porcelain or cultured marble, edged, cut out and packed for container shipping. Installation is not part of our standard supply: we supply fabricators, cabinet makers and project buyers who handle installation themselves, and on large projects we can discuss arranging it to help the job get done.
Almost every kitchen reduces to six layouts. What changes between them is not the material — it is how many pieces the run is split into, where the seams fall, and how much of the slab is lost to cutting. Below is how we break each layout down on the cutting plan.
One straight run, typically 2400–3600 mm. Cut from a single slab with no seam if the run stays under 3200 mm. Only the front edge is profiled; the wall edge is left raw.
Two parallel runs cut as separate pieces. We nest both on one slab where the vein direction allows, so the two sides read as the same stone.
The most common layout. Cut as two pieces with one seam at the inside corner — a single L-cut piece wastes roughly 40% more slab and cracks more easily in transit.
Three runs, two seams. We mark seam positions on the drawing before cutting so they land away from the sink and the cooktop, where the top is weakest.
All four edges exposed, so all four are profiled. Waterfall ends are mitred at 45° from the same slab to keep the vein running down the side.
One end unsupported. Overhang beyond about 200 mm in 20 mm quartz needs legs, brackets or steel support — we mark the bracket positions on the shop drawing.
A kitchen is the hardest place in a house for a stone surface. Hot pans land on it, acids get spilled on it, a sink sits in a hole cut through it, and it has to stay flat across three metres. These are the four things we fix before a kitchen job goes into production — they apply whichever stone you choose.
20 mm is the kitchen standard in quartz and natural stone; porcelain countertops are usually 12 mm. 30 mm where the client wants a heavier look, or a mitred build-up to 40, 60 or 80 mm on the front edge only.
This is where the materials actually differ, and it decides which one suits the client. Porcelain takes a hot pan straight off the hob; marble etches from a lemon within minutes.
Every kitchen top has holes cut through it, and that is where they fail. Internal corners are radiused, never cut square, and the narrow sections are braced before the piece is crated.
An L-shape is two or three separate pieces that have to read as one surface. We reserve the whole kitchen from a single production batch and lay the pieces out together before cutting.
We fabricate all five in the same workshop, so this is not a sales pitch for one of them — it is what we tell buyers when they ask.
| Stone | Where it works in a kitchen | What to tell the client |
|---|---|---|
| Engineered quartz | Worktops and islands. Non-porous, no sealing, and consistent enough across a batch that three pieces of one kitchen match. | Keep hot pans off it — the resin binder discolours under direct heat. |
| Granite | Worktops where heat resistance matters more than uniformity. Takes a hot pan without marking. | Natural material, so no two slabs are identical. Needs sealing on light colours. |
| Porcelain | Cooktop surrounds, outdoor kitchens, anywhere with direct sun. Heat and UV proof. | Harder to cut, so fewer edge profiles and a longer lead time on shaped work. |
| Marble | Islands and baking areas where the client accepts patina. Stays cool for pastry work. | Etches on contact with lemon, wine or vinegar. This has to be said before the order. |
| Cultured marble | Secondary counters, utility rooms, butler pantries. | Mohs 3–4 — we do not recommend it for the main worktop of a working kitchen. |
Four operations decide whether a countertop arrives ready to install or needs rework on site. This is the part buyers ask us about most, so here is exactly how we run it.
We cut 15 profiles in house. The first five below cover roughly 90% of kitchen orders; the rest are available on request.
A sharp arris softened to about R2. The most common contemporary edge and the simplest to produce.
Top arris rounded, bottom left square. Softer to the hand, still reads as a thin edge.
Both arrises rounded into a half circle. Forgiving on traditional kitchens and on 30 mm material.
A 6–10 mm chamfer at 45°. Catches light along the run; shows chips more than a rounded edge.
An S-curve for classical kitchens. Needs 30 mm material or a laminated build-up to show properly.
Two pieces joined at 45° so the edge reads as a 40, 60 or 80 mm slab. The vein is book-matched across the joint, or the corner gives it away.
The top is mitred at 45° and runs down to the floor. We cut both pieces next to each other on the slab so the vein carries over the corner.
A bonded strip under the front edge, rounded top and bottom, built up to 40 mm. The trade also calls it the French edge; the radius hides the bond line.
A small radius, about R5, on both arrises. A little softer than eased and a usual choice on 15 mm vanity tops.
The top arris rounded to about R10 while the face below stays flat. A middle ground between eased and half bullnose.
A 45° chamfer on both the top and the bottom arris. Gives a crisp, thinner look to 20 and 30 mm material.
A small square step at the top, then a rounded drop to the face. A traditional profile that needs 30 mm material or a mitred build-up.
A concave cove at the top running into a rounded lower edge. Decorative, and best on 30 mm material or a mitred build-up.
Three small rounds stacked down the face. Decorative, for 30 mm material or a mitred build-up.
The face is chiselled to a rough, split-stone texture instead of being polished. Used on rustic and farmhouse-style kitchens.
The cutout is made 3 mm smaller than the bowl on every side, then the inner edge is polished because it stays visible. Corners are radiused to R10 minimum — square internal corners are where quartz tops crack first. We need the sink model number, not just the dimensions.
Drop-in cutouts are 3 mm larger than the bowl and the edge is left unpolished under the rim. Cultured marble cannot take an integrated bowl, so plan an undermount or drop-in basin for it.
Cut to the manufacturer’s template with the required clearance to the front edge. On 20 mm quartz we leave a minimum 60 mm bridge between a cooktop cutout and a sink cutout.
35 mm standard faucet hole, drilled not punched. Additional holes for soap dispensers, air switches and pop-up outlets are marked on the drawing with centre distances.
A dimensioned drawing, a cabinet layout, or even a hand sketch with measurements. DXF and PDF both work. Tell us the slab colour and the edge profile.
A shop drawing within 48 hours: every piece numbered, seam positions marked, cutout centres dimensioned, and the slab count the job needs. You approve or mark it up.
Nothing is cut until the drawing comes back signed. Straight runs hold ±0.5 mm; radius and shaped work ±1 mm. Each finished piece is labelled with its number from the drawing.
Every piece is signed off against the approved drawing. The checks below are the ones that catch problems worth catching — the rest are covered by the slab’s own certification.
Length, width and every cutout centre measured against the signed shop drawing. Straight runs ±0.5 mm, shaped work ±1 mm, diagonal check on rectangles to catch out-of-square.
Profile checked against the template along the full run. Polished edges inspected under raking light for chatter marks; any chip over 0.5 mm means the piece is re-cut, not filled.
Straightedge across the width and along the length. Deviation over 1 mm per metre is rejected — a top that rocks on the cabinet run cannot be fixed on site.
All pieces for one kitchen laid out together under the same light and compared. Lot number recorded so a later reorder can be checked against it; a later batch can differ slightly, so order the whole kitchen at once.
For L, U and island jobs the pieces are laid out together before packing to confirm seams close and the vein runs continuous across the joint.
Each finished piece is photographed on the layout table with its number visible. The set goes to you before loading, so you see what shipped.
Breakage on arrival is the single biggest cost in importing fabricated stone. The packing below is what we have settled on after tracking claims across our shipments.
Each piece wrapped in foam, separated by plywood, stood on edge in a fumigated wooden crate with corner protection. Cutout areas get an extra foam collar because that is where a top snaps. Crates are strapped and labelled with the piece numbers inside.
Slabs ride on wooden A-frames, bundled and strapped, with foam between every slab. 105 slabs of 20 mm quartz fit in a 20 ft container.

Most of our kitchen work ships to cabinet makers and kitchen companies, so the top has to land on a cabinet run someone else built. These are the points where the two trades meet.
The most requested combination. A pure white top on white cabinets needs a vein or a warm cast, or the two whites fight each other. Calacatta-style greys and golds sit best.
Navy, charcoal and black cabinet fronts take a light top with visible movement. Solid white reads flat against a dark base.
Warm timber wants a warm-ground top — beige, cream or a grey with a warm cast. Cool blue-white quartz next to walnut looks grey-green under kitchen lighting.
| Dimension | Why it matters | Typical |
|---|---|---|
| Cabinet depth | Sets the top depth including overhang. | 600 mm base → 620–640 mm top |
| Front overhang | Covers the door face and the gap behind it. | 20–40 mm |
| Backsplash allowance | Whether the top ends at the wall or carries an upstand. | 100 mm upstand, or full height |
| Island overhang | Seating overhang beyond about 200 mm needs legs or brackets. | 250–380 mm |
| Appliance openings | Dishwasher and range positions affect seam placement. | 600 / 900 mm |

Quartz, for the main worktops and the island in most kitchens: it needs no sealing, absorbs within 0.04% water, and one 3200 × 1600 mm slab gives a finished piece of up to 3000 × 1500 mm, so most islands come from a single slab. One kitchen often uses more than one material, though. Porcelain suits the cooktop surround and outdoor kitchens, and cultured marble, at Mohs 3–4, belongs in butler pantries and utility rooms rather than on the main worktop.
In a kitchen it comes down to matching against heat. An L-shaped or U-shaped run is two or three pieces that have to read as one surface, and quartz cut from one production batch does that, with no sealing and a Mohs hardness of 6–7. Granite takes a hot pan without marking, but no two slabs are identical and light colours need sealing. On quartz, use a trivet: the resin binder discolours under direct heat.
The standard kitchen countertop height is 36 inches (about 914 mm) from the floor, made up of a 34½-inch base cabinet and a 1½-inch top. The cabinets set most of that height, so check them against the top you order. Our kitchen standard is 20 mm, which is thinner than 1½ inches; 30 mm suits a heavier look, and a mitred build-up of 40, 60 or 80 mm thickens only the front edge.
Front to back, a kitchen countertop is usually 620 to 640 mm deep on a 600 mm base cabinet, leaving a 20 to 40 mm overhang over the door face; the US standard is 25½ inches on a 24-inch cabinet. Along the wall there is no standard width, because the run follows the cabinets. Islands with stools carry a 250 to 380 mm seating overhang, and past about 200 mm in 20 mm quartz we fit steel brackets.
Start from the cabinets: the length of each run, the cabinet depth and the front overhang you want, usually 20 to 40 mm. Then mark the sink and cooktop positions, the dishwasher and range openings, and whether the top ends at the wall or carries an upstand. A dimensioned hand sketch is enough; add the sink model number. We return a numbered shop drawing within 48 hours. If the walls are out of square, your installer should template them on site.
Most kitchen countertops in quartz and natural stone are 20 mm thick, which covers almost every job; porcelain countertops are usually 12 mm. Choose 30 mm for a heavier look or for an island with a long unsupported overhang, or a mitred build-up that shows a 40, 60 or 80 mm front edge. We press quartz slabs in 15, 20, 25 and 30 mm, and keep 15 mm for vertical surfaces and light-duty tops.
Yes. We reserve the whole kitchen from one production lot, record the lot number on the packing list, and lay every piece out together under the same light before packing. For veined designs we nest the pieces so the vein runs on across a seam. Colour is consistent within a batch, but a later reorder from another batch can show a slight shade difference, so order the full kitchen at once or send us a sample to match.
Finished kitchen countertops have no minimum order, but freight on a very small order is high, and we tell you that before quoting. Stock slabs start from one slab, so check stock with us first. Slabs pressed to order start at one container, with up to five colours mixed, and slabs and fabricated tops can share it. Fabricated tops take about 30 days from the approved drawing.
Yes. We supply kitchen cabinets, and bathroom vanity cabinets too, as matching products alongside the quartz tops, so one order can cover both. Send the cabinet layout with your drawing: the cabinet depth sets the top depth and overhang, and the dishwasher and range positions decide where the seams fall.
It depends on the stone. Quartz needs only warm water with a mild detergent and a soft cloth; soak dried spills with water for a few minutes first, and keep oven cleaners, dishwasher detergent and oil soaps off it. Granite and marble take a neutral stone cleaner, and marble must be kept from lemon, vinegar and other acids. On any kitchen top, use a cutting board rather than cutting on the stone.
Many white designs, from pure white to gold-veined Calacatta.
