Granite skirting board price per meter: four numbers to fix before you compare
A granite skirting board price per meter is not one figure. Cut a 30 mm slab at 100 mm and a square meter yields 10 m; at 150 mm it yields 6.67 m. Thickness, strip height, edge profile and cut length — fix all four and two quotes can be compared.
What is the granite skirting board price per meter, and why will no factory name a figure first?
The answer first: the granite skirting board price per meter does not stand on its own, because a linear meter is not a product unit. It is the output of four choices: slab thickness, how tall the strip is cut, which profile is ground on the top edge, and how long each piece runs. On the same 30 mm slab, the material part of the meter price at 150 mm is 1.5 times the figure at 100 mm, and a round-over and a moulded profile differ in how many passes the wheel makes per meter. A number on its own tells you nothing about whether it is dear; it only tells you which of those choices it belongs to. We hold 30 mm slabs in stock, and Pink Hemp (G564 / G4564) is a common pick for skirting: even ground, fine grain, and it holds a thin edge without chipping. One point is often missed: the taller the strip, the fewer strips fit across a slab and the more offcut is left at the edges, and that waste comes back into the meter price. What follows splits the chain into four steps you can work out yourself: thickness, height, profile, fixed length.
Skirting is quoted by the meter but the slab is bought by the square meter. How do the two line up?
One division does it: meters per square meter = 1 m² ÷ strip height in meters. At 100 mm you get 10 m; at 120 mm, 8.33 m; at 150 mm, 6.67 m. Same slab, same material cost, a third fewer meters: 10 m at 100 mm and 6.67 m at 150 mm. So the material part of the meter price at 150 mm is 1.5 times the 100 mm figure. That is still pure arithmetic with no saw kerf: the blade takes a slice on every cut, so real yield is a little under the theoretical number, and how much depends on the blade. So ask one question up front: is this price based on 100 mm or 150 mm? If the answer does not come, he is quoting square meters and converting for you. You can check it in reverse too: multiply his meter price by 10 and it should land close to his square-meter price, and a wide gap means the two figures sit on different bases.
The taller the strip, the fewer meters fit in a container. How does that sum work?
Weight per meter first: volume = height × thickness × 1 m. At 100 mm high and 30 mm thick, 0.1 × 0.03 × 1 = 0.003 m³, times 2.7 t/m³, gives 8.1 kg per meter; 120 mm gives 9.72 kg; 150 mm gives 12.15 kg. Then the box: 346 m² of 30 mm slab in a 20ft container is 346 × 0.03 × 2.7 ≈ 28 tonnes. Spread over strips, 28 t ÷ 8.1 ≈ 3,456 m at 100 mm high, or 28 t ÷ 12.15 ≈ 2,304 m at 150 mm. The square-meter route and the weight route land almost on the same figure, which means quoting in square meters or in linear meters is one batch of material in two units, not two products.
| Strip height | Theoretical meters per m² | Weight per meter (30 mm thick) | Meters per 20ft container |
|---|---|---|---|
| 100mm | 10 m | 8.1 kg | about 3,456 m |
| 120mm | 8.33 m | 9.72 kg | about 2,880 m |
| 150mm | 6.67 m | 12.15 kg | about 2,304 m |
Rounding, chamfering or moulding the top edge — why can that only be charged by the meter?
Those operations are charged by the meter because they travel along the length. The wheel runs end to end, and one pass takes the same time whether the strip is 100 mm or 150 mm tall. So the processing cost is a cost per meter by nature, not per square meter. Fold it into a square-meter price and both heights get charged the same processing, which undercharges the tall strip and overcharges the short one. The more involved the profile, the more passes: one for a round-over, one for a chamfer, two or three for a moulded section — and the processing part of the meter price climbs with the pass count. Settle the profile before you discuss the number, never the other way round. In practice, ask for material and processing on two separate lines — material by the square meter, processing by the meter — and the two added together are what you actually pay per meter.
How long should one skirting piece be — by the wall, or by what the slab will yield?
Cut length for skirting does not start from how long a piece the slab will yield. It starts at the openings. Leave one closing piece on each side of every door opening, cut to the clear size from the frame to the corner. External corners take two pieces mitred at 45°, with a spare allowance on both sides of the joint; an internal corner is a butt joint — one piece runs into the returning wall and the next butts against its end — and 45° is kept for external corners, door surrounds and shaped returns. Then ask whether one man can carry the piece upright into a lift and turn it into a stairwell. If not, it goes in as two pieces and you gain another joint. Fix those and the length follows, and one length across a wall is what lets the bundles stack flat in the container. Cut too short and the joints double, the meters of edge polishing double with them, and the material you saved does not cover the extra processing.
Two suppliers are far apart on the meter price. How do you know it is the same thing?
Four questions align them: what slab thickness (30 mm or something else), what strip height (100 / 120 / 150), what profile on the top edge (round-over, chamfer, moulded), and what fixed length per piece. Change any one and the prices are not comparable — a 150 mm strip carries 50% more material than a 100 mm one, and a moulded edge carries an extra pass or two. Only when all four answers match do the numbers mean the same thing. Guangxi Shicai Stone Industry Co., Ltd. was set up in 2019, runs 20 large saws and produces 500,000 m² a year; cut-to-length skirting starts at 100 m² with 5 days to ship, and Pink Hemp can be quoted straight off those four answers. Keep one rule: compare meter prices only at the same thickness, the same height, the same profile and the same fixed length.
