Indonesian brick slips, 23 × 7 × 1.5 cm, for cladding walls where thickness and weight matter. Each slip is cut to a 1.5 cm body, so a wall gains the appearance of exposed brick without the load of a full brick — suitable for renovation, extensions, interiors and facades where the substrate cannot carry extra weight.
Minimum order: 1 × 20’ FCL — mixed items and sizes accepted, so you can load different blocks in the same container.
Summary: Indonesian brick slips 23×7×1.5 cm, ±59 pcs per m² with a 3 mm joint, ±0.43 kg per piece (±26 kg per m²). One 20ft container carries ±55,000 pcs (±935 m²) at a 24-tonne road limit. FOB Semarang, price on request.
What brick slips are, and why they are used
A brick slip is a thin slice cut from a fired clay brick. Instead of building a wall from full bricks, the installer fixes slips to an existing substrate with cement-based adhesive, leaving a small joint that is pointed afterwards. The result looks like an exposed brick wall, but adds roughly 26 kg per square metre instead of the 88 kg of full-body cladding brick.
In the UK this matters because most of the housing stock is already built. Refurbishment, loft conversions, extensions and internal feature walls all need brick surfaces without extra structural load — and in conservation areas and period properties, slips are often the practical way to match an existing brick bond on a smaller footprint. They are equally common on commercial fit-outs and shop fronts where a brick finish is wanted quickly and cleanly.
The UK market in numbers
The United Kingdom is a structural net importer of clay building bricks. In 2024 the UK imported about US$290 million of building bricks (HS 6904.10) while exporting only US$13.7 million — a net deficit of roughly US$276 million (OEC bilateral trade data, 2024). Domestic production cannot cover demand, which is why new suppliers from outside Europe are routinely taken on by UK merchants.
The thin brick segment specifically is growing: the global thin brick market was estimated at US$1.88 billion in 2026 and is projected to reach US$2.75 billion by 2033, a CAGR of about 5.6% (Coherent Market Insights). Growth is driven by refurbishment rather than new-build, because slips can be applied to walls that are already standing.

Brick slips or brick cladding? Decide by weight
Both give an exposed brick face; the difference is how much load the wall gains and how much wall area fits in a container. Slips add about 26 kg per square metre, cladding bricks about 88 kg. In the same 20ft container, slips deliver about three and a half times the wall area — which is why slips are the usual choice for refurbishment at volume.

Coverage and container loading
Because slips are shallow, a container fills up by weight long before it fills up by volume. That is the single most useful number when comparing suppliers: it decides your freight cost per square metre.
| Container | Pieces | Coverage | Gross weight | Limited by |
|---|---|---|---|---|
| 20ft | ±55,000 pcs | ±935 m² | ±24 t | Weight |
| 40ft | ±62,000 pcs | ±1,050 m² | ±27 t | Weight |
Assumptions, stated openly: clay density 1.8 t/m³ · 3 mm joint · practical volume 28 m³ (20ft) and 60 m³ (40ft) · road payload limits 24 t and 27 t · packing efficiency 85%. Recount them yourself — the arithmetic is the same one we use when we quote freight.
Packing
Slips travel on pallets of approximately 3,000 pieces (±51 m², ±1.3 tonnes), shrink-wrapped with edge protection. Carton count per pallet is confirmed on the packing plan for each order, because it depends on the stacking arrangement that best fills the container for your port.
Installation
Substrate preparation decides the result: the wall must be clean, sound and flat. Slips are fixed with cement-based adhesive using a notched trowel, pressed firmly, and left to set before pointing. Joints are typically 3 mm. On external walls a water-repellent sealer is applied after the mortar has cured. Any tiler experienced with large-format wall tiles can carry out the work — no specialist brick layer is required.

Frequently asked questions
What are brick slips?
Brick slips are thin cut clay bricks, normally 15 to 25 mm thick, fixed to a wall like tiles to give the appearance of a solid brick wall. They carry the same fired clay face as a full brick but weigh a fraction of it, so they can be used on refurbishment, extensions and internal features where a full brick wall would be too heavy.
What size are your brick slips?
Our export brick slips measure 23 x 7 x 1.5 cm, with a bevelled edge. That gives about 59 pieces per square metre with a 3 mm joint, and about 26 kg of brick per square metre.
How many brick slips fit in a 20ft container?
Approximately 55,000 pieces per 20ft container, about 935 square metres of finished wall, limited by the 24-tonne road payload rather than by volume.
Do brick slips need a specialist installer?
No. They are fixed with cement-based adhesive or mortar in the same way as ceramic tiles, with a 3 mm joint. Any tiler used to large-format wall tiles can install them.
Can brick slips be used on external walls?
Yes. Fired clay is frost-resistant and does not fade, and slips are widely used on external facades. For coastal or heavily exposed walls we recommend a cement-based adhesive and a water-repellent sealer after the mortar cures.
Do you supply samples before an order?
Yes. We send a sample box so you can check colour and thickness before committing to a container. Freight for samples is at the buyer's cost.
