天然麻石（花崗岩）Natural Granite — 麻石磚、麻石地磚、麻石馬路壆供應
大方公司自1983年起供應天然麻石（花崗岩）予香港政府及私人工程，產品包括麻石地磚、麻石外牆磚、麻石壓頂、天然麻石馬路壆及路緣石。六種表面處理、25款常用顏色，尺寸可按圖訂製，並備有 Fugro Technical Services Limited（HOKLAS 015）測試報告供物料呈交之用。本公司長期參與建築署、路政署、房委會、拓展署及水務署工程項目，並持有 ISO 9001:2015 認證（HKAS Q0351）。本公司只供應材料，不包括鋪設工程。
甚麼是天然麻石？麻石與花崗岩是同一種東西嗎？
是。「麻石」是香港及廣東地區對花崗岩（Granite）的慣稱，因表面佈滿深淺不一的礦物斑點，狀似麻點而得名。花崗岩由地底岩漿緩慢冷卻結晶而成，主要成分為石英、長石及雲母，質地堅硬、吸水率極低、耐磨耐候，是全球最常用的戶外鋪面及建築石材之一。香港的舊式石屋、碼頭、渠壆以至現代公園廣場、行人路面、馬路壆，都大量採用本地或進口麻石。
香港工程為何常用天然麻石？
- 行人路及公園廣場地面：燒面或荔枝面麻石地磚防滑耐磨，正常使用下只會磨蝕而不會崩裂，色調可維持數十年。
- 天然麻石馬路壆及路緣石：比預製混凝土壆更耐撞，常見於行車路邊、迴旋處及海濱長廊。
- 花槽、擋土牆及外牆：自然面麻石展現粗獷原石效果，拋光面則用於大廈外牆及大堂牆身。
- 樓梯級、壓頂及石椅：可訂製厚板及異形件，配合設計圖則加工。
天然麻石顏色：25款常用色
常見顏色包括白色黑點、各種深淺灰色、黑色、淺黃、橙黃、鮮紅、粉紅、淺啡及墨綠。每款均可配合不同面層加工。因屬天然礦石，顏色及礦物顆粒每塊都有細微差異，同一批次亦可能深淺不一，這是天然石材的正常特性，建議先確認樣板後落單。詳見本站文章〈天然麻石為何會有色差？〉。

天然麻石價錢
天然麻石地磚價格一般為每平方米三至四位數（港元），實際單價視乎顏色、面層、厚度、尺寸、訂購數量及交貨地點而定。天然麻石由礦山開採大方塊石料，經切割後再以機器或人手加工面層，工序與人造麻石不同，因此單價較人造麻石高；相對而言，天然麻石耐用度及防滑度更高，戶外使用壽命長，長期維護成本較低。歡迎提供圖則、BQ 或規格，本公司會列出可供應項目及正式報價。
最低訂量、交貨期及尺寸公差
- 最低訂量：每款每色 50 平方米起（馬路壆按件計，部分型號有現貨）。
- 交貨期：訂製尺寸一般為付款後約 45–55 個工作天，大車直達地盤路邊落貨，不包括二次搬運。
- 尺寸公差：天然麻石由天然石料以人手／機器切割，長、闊、厚度約有 2–3mm 公差，此為天然石材正常情況，不構成退貨、換貨或退款理由。
- 色差：天然石材顏色因批次而略有差異，建議確認樣板後落單。

常見問題
問：麻石有甚麼缺點？
答：天然麻石的主要限制是重量大（厚 30mm 約每平方米 80 公斤）、單價較人造石高、顏色有天然差異，以及拋光面遇水較滑不宜用於戶外地面。選對面層和厚度後，麻石在耐用度及防滑度上是戶外鋪面材料中最可靠的選擇之一。
問：花崗岩有輻射嗎？可以放心用嗎？
答：所有天然岩石都含微量天然放射性元素，建築用花崗岩一般處於正常背景水平，符合建材放射性標準，全球公共建築及行人路廣泛使用。如工程有特定要求，可向本公司索取相關文件。
問：麻石地磚一平方米多少錢？
答：一般為每平方米三至四位數港元，視乎顏色、面層、厚度及數量。請提供規格索取正式報價。
問：燒面和荔枝面哪種較防滑？
答：兩者均符合戶外地面防滑要求。荔枝面凹凸較深，防滑度最高，適合斜路及濕滑位置；燒面較易清潔，觸感較平滑，是公園廣場及行人路最常用的面層。
問：可以按圖則訂製尺寸嗎？最少要訂多少？
答：可以，長闊 100–2800mm、厚 8–100mm 均可訂製，每款每色最低訂量 50 平方米。
問：大方公司提供鋪設服務嗎？
答：不提供。本公司只供應材料，鋪設工程由承建商安排。

What is “ma shek”? Is it the same as granite?
Yes. 麻石 (ma shek) is the everyday Cantonese name for granite (花崗岩), so called because of the speckled “sesame” pattern of its mineral grains. Granite forms when magma cools slowly underground; it is composed mainly of quartz, feldspar and mica, and is hard, very low in water absorption and highly resistant to abrasion and weathering. From Hong Kong’s historic stone houses, piers and drainage channels to today’s parks, plazas, footpaths and road kerbs, granite is everywhere in the city.
Why Hong Kong projects specify natural granite
- Footpaths, parks and plazas — flamed or bush-hammered granite paving is slip-resistant and hard-wearing; under normal use it wears rather than cracks and holds its colour for decades.
- Road kerbs and edgings — granite kerbs resist impact far better than precast concrete and are common along carriageways, roundabouts and waterfront promenades.
- Planters, retaining walls and facades — natural-split granite gives a rugged quarried look; polished granite is used on building facades and lobby walls.
- Steps, copings and benches — thick slabs and special shapes are cut to drawings.

Colours: 25 standard granite colours
Typical colours include white with black speckle, a range of light to dark greys, black, light yellow, orange-yellow, red, pink, light brown and dark green, each available in any finish. Because granite is a natural mineral, colour and grain vary slightly from piece to piece and between batches — this is a normal characteristic of natural stone. We recommend approving a sample before ordering. See our article Why does natural granite vary in colour?

Natural granite prices in Hong Kong
Natural granite paving typically costs from three to four figures (HKD) per square metre, depending on colour, finish, thickness, size, quantity and delivery location. Granite is quarried in large blocks, sawn, and then surface-finished by machine or by hand — a different process from artificial granite, which is why the unit price is higher. In return it offers greater durability and slip resistance, a long service life outdoors and lower long-term maintenance. Send us your drawings, BQ or specification and we will list what we can supply with a formal quotation.
Minimum order, lead time and tolerances
- Minimum order: 50 m² per colour and size for paving (kerbs are priced per piece; some profiles are held in stock).
- Lead time: custom sizes approx. 45–55 working days after payment; delivery by large lorry to site kerbside only, no secondary handling.
- Dimensional tolerance: natural granite is cut from natural stone by hand or machine, so length, width and thickness carry an approx. 2–3 mm tolerance. This is normal for natural stone and does not constitute grounds for return, exchange or refund.
- Colour variation: natural stone colour may vary between batches; sample confirmation is recommended.

Frequently asked questions
What are the drawbacks of granite?
Weight (30 mm slabs are roughly 80 kg/m²), a higher unit price than artificial stone, natural colour variation, and polished finishes becoming slippery when wet, so they are not used on exterior floors. With the right finish and thickness, granite remains one of the most durable and slip-resistant exterior paving materials available.
Is granite radioactive? Is it safe?
All natural rock contains trace natural radioactive elements. Building granite is generally at normal background levels and complies with building-material radioactivity standards; it is used in public buildings and footpaths worldwide. Documentation can be provided on request where a project requires it.
How much does granite paving cost per square metre?
Typically three to four figures (HKD) per m², depending on colour, finish, thickness and quantity. Send your specification for a formal quotation.
Which is more slip-resistant, flamed or bush hammered?
Both meet exterior floor requirements. Bush hammered has a deeper texture and the highest slip resistance, suited to ramps and wet areas; flamed is smoother underfoot and easier to clean, and is the most common finish for parks, plazas and footpaths.
Can sizes be cut to drawings? What is the minimum order?
Yes — 100–2800 mm in length/width and 8–100 mm thick. Minimum order is 50 m² per colour and size.
Does Tai Fong install?
No. We supply materials only; installation is arranged by the contractor.
