Product Detail
Staircases Where Every Step Matches
An outdoor staircase is a dimension-controlled product disguised as a landscape element. Every tread must sit level, every riser line must align, and the whole run must read as one continuous piece of stone. Sea Wave Granite (浪花白) outdoor steps bring a warm grey base with evenly distributed wave-pattern movement to exterior staircases, garden steps, terraces, and thresholds - and the way the steps are cut and matched decides whether the staircase looks engineered or improvised.
The Pain Point: A Staircase Assembled From Unmatched Stock
The classic outdoor-steps failure starts with sourcing treads and risers as loose stock. Thickness varies between pieces, so the tread surfaces step up and down instead of running level. Edge profiles differ between batches, so the nose line wanders along the staircase. Background tone shifts partway up the run, and the wave-pattern movement suddenly changes density at step eight. On a five-step garden stair the defects are visible; on a resort terrace staircase with twenty treads, the staircase becomes the one element every guest comments on.
The impact is direct: re-cutting or replacing steps means a second production cycle and a second freight cost, and the staircase - usually the last element installed before handover - becomes the reason the handover slips. For the contractor, level and riser tolerances are not cosmetic preferences; an uneven exterior stair is a trip hazard and a liability.
Our Solution: One Batch, Calibrated Thickness, Numbered in Laying Order
Apexstone cuts Sea Wave Granite staircases as matched runs: for multi-step projects, treads and risers are cut from the same slab batch to maintain color and pattern consistency across the full staircase. Thickness is calibrated across the run for level installation, and each step is CNC-cut to exact dimensions with eased or bullnose edges finished to the same specification. Steps are packed and numbered in installation order, so the run assembles in sequence without sorting on site.
How the Process Works
Step slabs are selected for a consistent warm grey base and evenly distributed wave pattern, then sawn and CNC-cut to the specified tread and riser dimensions. Edge profiles - straight, eased, bullnose, or custom - are finished per the drawing. Flamed and brushed finishes add texture for wet exterior conditions; polished is available for interior staircases. Each piece is inspected for dimensional tolerance and edge quality before packing, and CAD pre-visualisation confirms tread, riser, and profile details before cutting begins.
What That Delivers to the Buyer
For contractors, a matched run means the riser line stays straight and the treads sit level on the first installation pass - no on-site sorting, no shimming, no re-order. For importers serving northern-climate markets, the frost-resistant granite and slip-resistant flamed or brushed finishes answer the two questions landscape architects ask first about exterior steps. And because the steps are cut from the same batch as the surrounding paving when ordered together, stair and pavement read as one design.
Steps for Every Situation
Garden and Terrace Steps
Garden steps and stepping stones create natural, durable transitions between landscape levels. The warm grey tone sits comfortably beside timber, render, and planting, in square, rectangular, and irregular formats.
Porch and Balcony Steps
Porch and balcony steps provide a weather-resistant building entry with the same matched-run discipline: exact dimensions, eased or bullnose edges, and slip-resistant finishes for wet conditions.

Procurement FAQ
- Which thickness should exterior stair treads use?
- Within the 20/30/40 mm (3/4 / 1-1/4 / 1-1/2 inch) range, thickness is matched to span, support detail, and expected traffic. Confirm the stair section with your engineer and specify the working thickness on the cutting drawing.
- Can the staircase match the surrounding paving?
- Yes. When steps and paving are ordered together, they are allocated from the same slab batch for consistent color and wave-pattern movement.
- Which edge profile for a garden staircase?
- Eased edges are the common exterior choice; bullnose suits locations where hands and feet contact the nose. Confirm per the drawing.
- How do we get a quotation?
- Send step dimensions, tread and riser profiles, edge details, and finish requirements. MOQ starts from 20 m²; lead time is 25–35 days from drawing approval.
