Steel-structure pools
3.5 mm hot-dip galvanized panel, bolted bracing, hot-air welded PVC liner. Any rectangular or irregular shape, above or below ground.
DetailsFactory-cut galvanized panels, bolted on site, sealed with a welded PVC liner. Built for rooftops, retrofits and projects that cannot wait for concrete to cure.
A pool is a box that holds water, a circulation loop that cleans it, and — if it is heated — a plant room that keeps it at temperature. We supply all three, or the structure alone.

DetailsFactory-built shell, delivered with its circulation system. For villas and small hotels where the pool is a finished object, not a construction site.
DetailsCirculation, sand filtration, UV and ozone disinfection, water-quality control. Sized from the turnover you need, not from a catalogue page.
DetailsAir-source pool and hot-spring heat pumps, from 9 kW to 290 kW. Selected against the actual heat loss of your pool, not its volume.
DetailsEvery pool is a steel box, waterproofed from the inside. The structure carries the water; the liner keeps it in. Nothing depends on a screed that might crack.
Levelled concrete slab or compacted gravel. Flat within tolerance; no curing time needed before assembly.
Hot-dip galvanized, bolted at flanges, ribbed bracing on the outside face. Carries water load and earth pressure.
Added on heated pools to cut standing heat loss; omitted on seasonal or unheated pools.
Hot-air welded into one continuous skin. No joints, no reliance on the panel being watertight.
Design depth 1.0 m or 2.0 m; other depths to project.
Section drawing, not to scale. Numbers opposite refer to the five layers.
Panels are bolted, not poured. No formwork, no curing time, no site water.
A fraction of the weight of a concrete pool — which is why rooftops and existing structures accept it.
A damaged panel or a torn liner is a local repair, not a demolition.
We write this comparison knowing it costs us some orders. It also means the advice on the other pages is worth reading.
| Steel-structure pool | Cast-in-place concrete pool | |
|---|---|---|
| Construction time | Factory-cut panels bolted on site; assembly typically one to two weeks | Rebar, formwork, pour, then a curing period before finishing |
| Site conditions | Mainly dry work; rain delays welding, not the structure | Wet trades; curing is sensitive to rain and temperature |
| Self-weight | Light — accepted by rooftops, mezzanines and existing slabs | Heavy — usually needs structural reinforcement, often impossible on a roof |
| Waterproofing | Continuous hot-air welded PVC liner, independent of the structure | Depends on concrete plus a membrane; a crack becomes a leak |
| Later modification | Panels can be cut, extended or deepened | Requires breaking out; expensive |
| Best suited to | Hotels, schools, villas, rooftops, irregular shapes, refurbishment, fixed opening dates | 50 m competition pools, poor ground, high water table, a client who already has a cheap concrete crew |
Most of the pools we are asked to build are the ones a concrete contractor has already said no to. Rooftops, basements, existing buildings, and pools with a fixed opening date.
On-site assembly for a pool of this class typically takes one to two weeks, depending on size, site access and scope. The schedule is confirmed per project — we do not quote a fixed number of days before seeing the site.
Level, compacted base — slab or gravel — then panel layout marked to drawing.
Floor and wall panels bolted to the bracing grid. The box is squared and levelled before anything else.
PVC liner hot-air welded on site into one seamless skin, then coping and decking.
Pipework, filtration, disinfection, heating equipment set and connected.
Filling, leak test, water balance and equipment commissioning.
Commissioning and operator training included. Drawings and as-built documents issued.
Drawings, video calls and daily questions. No charge.
One or two technicians on site, your labour force.
Our own crew builds it, quoted per project.
Client names are withheld. References and site photographs are available on request during a live enquiry.

Five things get you a real quotation instead of a range: length, width and depth; what the pool is for; heated or unheated; structure only or complete plant; destination port.
