What Is the Price of 白色砾石 per Tonne?

There is no single 白色砾石 price per tonne, because '白色砾石' is a colour-graded stone 和 freight dominates the delivered cost. Plan with the structure: one 20 ft container holds about 24–27 tonnes, a 20 mm layer needs roughly 30–34 kg per square metre, 和 one tonne covers about 30–33 square metres. The per-tonne figure then moves with grade, grain band, washing 和 packing, quoted as separate material, packing 和 freight lines to your named port.

Treat any quotation offering one flat per-tonne rate with no grade definition as unpriceable rather than cheap. Two suppliers can both write '白色砾石' 和 be selling different products: a bright washed limestone chip, a harder marble or quartz chip that holds its tone outdoors, or a general run where a few grey 和 buff particles turn a bright bed patchy in sunlight. The rest of this article walks through what actually sits inside a 白色砾石 price per tonne, how to convert it into a cost per square metre you can budget, 和 how to compare two 白色砾石供应商 quotations fairly.

Why 白色砾石 Costs More Than Grey Gravel

白色 gravel is priced on a ladder defined by brightness 和 the reject rate, 和 the rungs are far apart. A grey gravel moves almost everything the screen produces; a white grade has to be colour-sorted 和 the discoloured grain — grey, buff, iron-stained — rejected. Because that reject is sold as something cheaper or discarded, the yield of true first-grade white stone from a deposit, 不会 the deposit itself, is what the per-tonne price is really buying. A harder rock such as marble or quartz costs more than limestone 不会 for colour but for the durability that keeps the white bright under weather 和 footfall.

This is why the specification belongs in the enquiry before the price does. Ask each supplier to state the rock type, the grain band in millimetres with a sieve analysis, 和 a brightness held as a sealed wet reference sample — wet, because colour shifts as stone dries. A price quoted against that definition is comparable; a price quoted against the words '白色砾石' is a different 产品 every time you re-order, 和 the difference usually appears in container two, when the tone drifts 和 the bed has to be matched.

What Sits Inside a 白色砾石 Price per Tonne

A 白色砾石 price per tonne is a stack, 和 each layer can be queried. The material layer covers the rock cost, crushing 和 screening, washing, drying fuel 和 bagging labour. The logistics layer covers inland haulage from the plant, port charges, documentation 和 ocean freight to your named port. On a dense, low-value-per-tonne mineral like gravel, the logistics layer is commonly the larger share of the delivered figure — which is why the same stone can land at very different totals at two ports, 和 why a quotation that hides freight inside a per-tonne number hides the part that actually varies.

Moisture is the layer buyers most often miss, 和 it is pure loss. Gravel is sold by weight, so water in the load is freight you pay ocean rates on 和 产品 you never see. At a 2% moisture content, a 25-tonne container carries about half a tonne of water; specify a moisture maximum on an oven-dry basis with a test report, 和 the same container delivers measurably more saleable stone for the same freight. Washing quality works the other way: fines are also weight you ship, but fines that arrive on a bright white surface are a cleaning bill 和 a hazy first impression, so the dust limit earns its line in the specification.

How to Convert a 白色砾石 Price per Tonne into a Price per Square Metre

Converting the per-tonne price into a cost per square metre is the single most useful piece of arithmetic in this trade, because it makes every quotation — per tonne, per bulk bag, per pallet — directly comparable. Loose dry 白色砾石 runs at roughly 1.5–1.7 tonnes per cubic metre. A 20 mm dressing therefore needs about 30–34 kg per square metre, which means one tonne covers roughly 30–33 square metres at that depth. A 10 mm dressing halves it to about 15–17 kg per square metre; a 40 mm layer doubles it to about 60–68 kg.

Run the same conversion at container scale for budgeting. A 20 ft container of 24–27 tonnes covers roughly 700–800 square metres at 20 mm, or about 300–330 linear metres of a 0.6 m-wide garden pathway at the same depth. Add 5–10% for settlement, edge build-up, spillage 和 later top-ups, 和 increase the allowance where wind, foot traffic or raking will disturb the surface. Price the scheme per square metre at the depth you actually specify 和 every supplier becomes comparable — 和 every coverage promise a supplier makes becomes checkable before the order, 不会 after the second container.

What Is the Minimum Order 数量 (最小起订量) for 白色砾石?

The commercial floor for exported 白色砾石 is one 20 ft container, about 24–27 tonnes loose, because gravel is dense enough to reach the container's weight limit long before it fills the cube — the same reason a 40 ft container is 不会 the better deal, since its payload is only marginally higher under the same weight limits 和 destination road rules often cap axle loads further. Because 最小起订量 is counted per 产品 rather than per grade, ask for the minimum order quantity per grade, 不会 per 产品 line, so you know exactly where the floor sits on the white chip you actually want.

Within that floor, how the supplier treats 最小起订量 across grades matters more than the headline number. A supplier who will split one container across two or three grain bands — say a 6–10 mm chip for resin-bound work 和 a 20–40 mm chip for loose beds — lets you meet the 白色砾石 最小起订量 with a mixed first order, which is exactly what a first-time buyer needs to test the market. Expect a small handling premium for the mixed load 和 treat it as cheap insurance against committing 24–27 tonnes of one size you have never sold. Bagged 和 jumbo-bag orders carry their own 最小起订量, usually expressed in pallets or units, so get the policy in writing before the price is agreed.

How Do You Compare Two 白色砾石 Suppliers Fairly?

Compare two 白色砾石供应商 quotations only after pinning four things on both sides: the rock type 和 grain band with a sieve analysis, the brightness method with a sealed wet reference sample, the moisture maximum on an oven-dry basis, 和 the packing format with unit-mass tolerance. Then normalise everything to cost per square metre at your specified depth, adjusting for moisture — a damp, dusty grade at a low per-tonne rate can cost more laid down than a clean, dry, narrow grade at a higher rate, once freight, fines 和 top-up are counted. The conversion removes the illusion that per-tonne numbers create.

Close the comparison with evidence, 不会 adjectives. Ask each supplier for a certificate of analysis, loading photographs with lot references, 和 a retained sealed reference sample held by both parties. On a limestone versus marble question, a drop of dilute acid on a sample settles it: limestone fizzes, marble fizzes only faintly 和 quartz 不会 at all, 和 that single test tells you how the bed will weather. Two random 1 kg scoops from different pallets, wetted 和 compared in daylight against the sealed reference, show whether the brightness holds across the lot. A supplier who welcomes these tests is quoting a 产品; one who resists them has told you what the shipment is before it sails.

What Moves 白色砾石 Prices, 和 How Do You Lock Them?

Four forces move 白色砾石 prices between quotation 和 delivery. Season is the first: construction demand peaks, a rainy season raises washing 和 drying costs, 和 the Chinese New Year shutdown compresses production 和 vessel space into the weeks either side. Energy 和 fuel are the second — drying fuel 和 inland haulage feed directly into both material 和 freight lines. Container freight rates are the third 和 often the largest swing on the delivered figure. Currency is the fourth, 和 it is the reason quotes are usually dollar-denominated with a stated validity.

The contract levers that hold a price are simple 和 worth writing in. Fix a price validity window of 30–60 days in the purchase order; on annual programmes, agree a base price with a stated adjustment cap tied to published freight indices rather than open-ended renegotiation. Book vessel space before the peak season rather than after, order the full project quantity from one production lot so brightness cannot drift between phases, 和 keep per-lot retention sacks so any later top-up order can be matched to the sealed reference. A 白色砾石 price locked this way is 不会 just cheaper on average — it is predictable, 和 predictability is what lets a merchant quote retail with confidence.

常见问题

What is the price of 白色砾石 per tonne?

There is no single price, because brightness 和 the reject rate set the material cost — a tight white limestone or marble chip costs more than a grey run of the same rock — 和 freight dominates the delivered figure. Plan with the structure: one 20 ft container holds about 24–27 tonnes, 和 a quotation should be split into material, packing 和 freight lines to your named port, each tied to a stated rock type, grain band 和 sealed wet brightness reference.

What is the minimum order quantity (最小起订量) for 白色砾石?

The commercial floor is one 20 ft container, about 24–27 tonnes loose, because gravel reaches the container weight limit before it fills the volume, which is also why a 40 ft container is 不会 the better deal under the same weight limits. Ask for the 最小起订量 per grade rather than per 产品 line; many suppliers will split one container across two or three grain bands for a small handling premium, letting a first-time buyer meet the 白色砾石 最小起订量 with a mixed test order.

How many square metres does one tonne of 白色砾石 cover?

At a loose bulk density of roughly 1.5–1.7 tonnes per cubic metre, one tonne covers about 30–33 square metres at a 20 mm depth, about 60–65 square metres at 10 mm, 和 about 15–16 square metres at 40 mm. A 20 ft container of 24–27 tonnes therefore covers roughly 700–800 square metres at 20 mm, or about 300–330 linear metres of a 0.6 m-wide garden pathway; add 5–10% for settlement, edges 和 spillage.

Why is 白色砾石 more expensive than grey gravel?

The premium buys colour sorting, 不会 colour alone: a grey grade moves almost everything the screen produces, while a white grade has to reject the grey, buff 和 iron-stained grain, 和 the yield of first-grade white stone from the deposit is what the price really pays for. A harder marble or quartz chip costs more than limestone for the outdoor durability that keeps the white bright, 和 tighter screening to hold a narrow band adds further reject cost.
