Sea Wave Granite Steps — Textured Treads for Outdoor Stairs and Garden Steps

Flamed thermal Sea Wave granite steps are cut-to-size treads and risers in 30mm thickness, made for outdoor stairs, garden paths and terraced levels that stay safe underfoot for decades.

Sea Wave is a Chinese white granite with a bright light ground crossed by fine flowing gray veining. On a long flight the wave pattern carries the eye up the run and reads far warmer than plain gray stonework. As a dense siliceous rock rated 6–7 on the Mohs scale, it takes a textured tread without wearing smooth, survives frost and de-icing salts, and keeps its pale color year after year.

Steps are normally supplied inside a wider hard-landscaping package: the same batch is cut as Sea Wave granite pavers for the landings and Sea Wave granite pool copings for any waterside entry, so the flight, landing and pool edge share one material.

A stair order starts from your setting-out drawing: riser count, goings, landing positions and edge profile. Treads are cut to those exact dimensions, with a rounded or chamfered nosing and optional anti-slip grooves near the leading edge. Each piece is numbered against the flight layout before crating.

The workshop photograph shows cut treads at the finishing stage: textured faces are applied after cutting, noses are ground smooth, and thicknesses are calibrated so every riser in the flight reads level. Curved flights, winders and quarter-landings are cut from the same full-size slab stock as straight runs.

Steps are the highest-risk surface on a project, so the test paperwork matters more here than anywhere: every export batch is checked for tread slip resistance, frost resistance and absorption, giving projects the documented data they require.

In practice the dense body means treads survive rain, frost and de-icing salts without flaking, and the textured face keeps its grip as it ages rather than polishing smooth under foot traffic. There is no sealing regime to maintain on exterior flights; a periodic wash is all the upkeep the work needs.

Finished step blocks are laid out flat in the factory for numbering and tone checking before crating, so a flight arrives on site as a matched, ready-to-lay set rather than a pile of slabs.

The same material covers the full vertical range of a project. Outside, low garden steps and pathway pieces work in thick, textured slabs; at the entrance the formal flight takes a rounded nosing and anti-slip grooves; inside, the staircase can continue in honed or polished treads up to the upper floors.

Pathway stepping stones through lawns and planting are cut as thick individual slabs set into the ground, spaced to a comfortable stride and laid level — a soft, informal counterpoint to the formal flight at the door.

Interior flights pair the pale veined treads with wood or steel handrails; the stone reads bright under hallway skylights and needs no treatment beyond the usual interior floor care.

Three things decide how a stair order arrives on site, and all three are controlled inside our Shuitou factory. First, every tread and riser for one flight comes from a single production batch and is tone-matched before numbering, so the veining runs up the whole flight without a shift. Second, flight pieces are nested against the slab layout to optimize yield, which trims waste from the special long dimensions steps require. Third, crates are built with dedicated nosing protection and separators, so the sea voyage ends with zero chipped edges.

Orders scale from one entrance flight to full container programs for housing developments, with sample steps available for approval first. Drawings are quoted within 48 hours and curved or shaped flights can be confirmed with 3D samples before production. Production lead time is 18–25 days after drawings are confirmed, plus 25–35 days of ocean freight from Xiamen to most major ports.
