What Is the Best Gravel for a 日式庭院, 和 Which Grade Works Around a Pool? — The best gravel for a Japanese garden is a washed, rounded, single-stone 6–10 mm or 10–20 mm grade in a light granite or quartz — fine enough to rake into karesansui patterns yet stable underfoot. Around a pool, the same rounded, inert gravel works if it is smooth, non-slip 和 free of lime that would leach into chlorinated water.
水景用哪种抛光鹅卵石最好? — 水景用最好的抛光鹅卵石是通体抛光——绝非打蜡或树脂涂层——的 20–40 mm 惰性石材,如黑色玄武岩或灰色花岗岩,铺在水线带和溢流口两侧,而不是铺满整个水下床面。50 mm 厚度下每吨约铺 12–14 m²,20 尺柜可装 24–27 吨。
What Is the 最小起订量 for 装饰沙? — The typical 最小起订量 for 装饰沙 is one 20 ft container, about 24–27 tonnes when loose-loaded, but the minimum that actually affects a buyer is the per-grain-band 和 per-colour sub-minimum, which is usually far lower. Most suppliers also accept a 3–5 tonne trial or a 10–12 tonne partial at a small premium, 和 will mix two or three bands 和 colours inside a single container rather than insisting on a full band per load.
