Pergola aluminium and quality: why it matters
An outdoor pergola stays up for decades, so the base material and the surface finish are not minor details. Below we walk through what an aluminium structure, a certified finish and in-house manufacturing mean in practice — and why these three factors decide long-term durability.
The base material: UNI 6060 aluminium with INOX fixings
The load-bearing profiles are made from UNI 6060 alloy aluminium, and the fasteners are INOX — stainless steel — screws. This pairing matters because an outdoor structure is exposed all year round to rain, humidity and temperature swings.
Aluminium does not rot and does not rust, yet it is light and load-bearing, so large spans are possible without an oversized, heavy frame. Maintenance needs are low: the surface does not need to be treated year after year the way timber structures do. The stainless fixings hold where ordinary steel screws would eventually seize with rust — keeping the joints reliable over the long run.
The finish: QUALICOAT-certified powder coating
The profiles are finished with QUALICOAT-certified powder coating. QUALICOAT is a certification of powder-coating quality that ties the coating's adhesion, abrasion resistance and durability to controlled requirements — it is not just about colour, but about how well the coating stays intact under outdoor exposure.
For coastal, salty-air environments there is a separate QUALICOAT SEASIDE certification that calls for enhanced corrosion protection. The surface is produced without silicone sealing and without visible screws, so the result is clean and composed — no exposed joints or after-sealed gaps that would discolour over time.
Structural solutions in the Climax bioclimatic range
Quality does not stop at the material — the structural details decide whether a pergola still works well years later. In the Climax bioclimatic pergolas the posts are built with an integrated rainwater chamber: against the standard Climax post of 8.5×8.5 cm, the chambered version uses a 16×16 cm post, while the Flow version has a 20.5×20.5 cm post with a 13×13 cm chamber inside.
The structure is tied together by a 22 cm-high perimeter beam, and drainage runs hidden through the posts — there are no externally routed pipes. The posts are inspectable, meaning they can be opened for maintenance, so the drainage path stays accessible. On request the structure can be thermally insulated with expanded polystyrene.
Manufacturing kept in one set of hands
RGM Italia keeps the entire production chain in one place, in a 30,000 m² plant — from casting the aluminium to inspecting the finished structure. This is not an assembly shop that joins together ready-made parts, but a manufacturer that owns the whole process.
For the customer this means quality consistency: the same plant is responsible for the alloy, the profile and the final check, so tolerances and surface quality are predictable from one unit to the next. The survey and installation in Hungary are carried out by Riczu, so manufacturer-grade quality is traceable right through to on-site work.
Why all this matters in the Hungarian climate
In Hungary a pergola has to withstand the full load of four seasons: summer heat, autumn and winter precipitation, alternating frost and thaw. This is where aluminium and a certified finish show their advantage — the structure does not corrode, does not warp, and does not require regular surface treatment.
The integrated, hidden drainage carries rainwater away in an orderly way, so it does not pool on the structure. Taken together, this delivers a long service life, low maintenance and a consistently refined appearance — which is why it pays to look at the material and the finish at the point of choosing, not just the visual result.
