Sea Wave Granite Setts — Frost-Tested Cubes for Edging and Borders

Tumbled Sea Wave granite cube stones are small 100x100x50mm setts for flower bed edging, garden borders and landscaping details, made for schemes that need a traditional cobblestone texture that stays crisp for decades.

Sea Wave is a Chinese white granite with a bright light ground crossed by fine flowing gray veining. In small formats the wave pattern reads as subtle movement along the edge rather than a busy surface, which keeps edging visually quiet behind the planting. As a dense siliceous rock rated 6–7 on the Mohs scale, the setts resist the scuffing, frost and weed pressure that wear softer edging stones down.

Setts are usually supplied as part of a wider garden package: the same batch is cut as Sea Wave granite pavers for paths and terraces, and as Sea Wave granite wall panels for raised beds and boundary walls, so one stone runs through the whole garden. Raised stone planters and tree pits use the same setts and caps, which means a courtyard can be edged, bedded and capped from one consistent material list.

The standard cube is 100x100x50mm, sold by the square meter and laid on edge or flat depending on the look the drawing calls for. Alongside the setts we cut edging strips, flat wall caps and corner pieces to size, so an edging run can go straight from the drawing without masons carving on site.

Two finishes cover most garden work. Rounded setts are gently finished for the soft, established edge that suits cottage-style planting; natural split faces keep the quarried character and show the gray wave veining most clearly. Both are available on the same 100x100x50mm body. Raised planters are normally finished with a flat cap cut from matching slabs, so the rim of a planter sits level and comfortable at seating height.

Edging lives through every weather extreme a garden offers: saturated soil in winter, freeze-thaw cycles, fertilizer splashes and occasional impact from mowers and tools. Sea Wave setts are checked for frost resistance and low absorption before packing, so the batch performs the same in a cold northern garden as in a coastal one.

Because granite absorbs very little water, ice has almost nothing to expand on inside the stone, and the dense mineral surface keeps its color without sealers — the same quality that makes the material the default choice for public works across Europe. There is no annual treatment; an occasional wash is all the upkeep the work needs.

Larger garden projects are often supplied from stocked slabs as well as setts, which is how steps, caps and special pieces are cut from the same batch as the borders.

Three things decide how a garden order arrives on site, and all three are controlled inside our Shuitou factory. First, setts, strips and caps for one project are sorted from a single production batch, so the veining stays consistent around the whole garden. Second, formats are nested against the slab layout to optimize yield, which trims waste and lowers the cost per meter of border you actually pay. Setts are sorted by height before crating too, so rows lay to a consistent line without shimming, which keeps laying fast and the finished border straight. Third, crates are built with edge rails and corner protectors so the sea voyage ends with zero chipped setts.

Orders scale from a sample pallet for a single flower bed to full container loads for housing developments, with trial pallets flowing straight into repeat container orders without re-approving the stone. Drawings are quoted within 48 hours, and shaped edging can be confirmed with 3D samples before production. Minimum order is 100m² per format; standard lead time is 18–25 days, plus 25–35 days of ocean freight from Xiamen.
