Are Citroen Relay Vans Galvanised? The Short Answer

Yes — Citroen Relay vans use galvanised steel for a significant portion of their bodywork, particularly on later generations built from 2006 onwards. The Relay shares its platform with the Peugeot Boxer and Fiat Ducato, all produced through the Sevel joint venture in Italy, and all three benefit from the same galvanised panels and multi-stage corrosion protection process. That said, "galvanised" doesn't mean "rust-proof" — it means the outer body panels are coated in a thin layer of zinc that dramatically slows the onset of surface rust, especially where paint has been chipped or scratched.

Older Relays (pre-2006) had less comprehensive galvanisation and are more prone to rust in known hotspots, while newer models enjoy better cavity waxing, improved seam sealing and factory-applied underbody coatings. If you're looking at a used Relay, the age and mileage of the van, combined with how it's been stored and used, will matter far more than the marketing claim of "galvanised bodywork" alone.

What Galvanisation Means for a Panel Van

Galvanisation is the process of applying a protective zinc coating to steel to prevent it from oxidising — or rusting — when exposed to moisture and air. For a working van like the Citroen Relay, which spends its life outdoors, on salted winter roads and being loaded with damp cargo, this protective layer is genuinely valuable. The zinc acts as a sacrificial barrier: it corrodes in preference to the steel underneath, so even if the paint gets chipped, rust doesn't immediately eat into the panel.

Galvanised vs Painted Steel: What's the Difference?

Standard painted steel relies entirely on the paint film to keep water and oxygen away from the metal. Once that film is breached — by a stone chip, a ladder scrape, or a careless loader — rust can spread rapidly beneath the paint, lifting it and creating the familiar bubbling you see on older commercials. Galvanised steel, by contrast, has a zinc layer bonded to the surface before painting. Even when the paint is damaged, the zinc keeps working, which is why properly galvanised panels can go decades before showing serious corrosion. Most modern vans, including the Relay, use hot-dip or electro-galvanised steel on their outer skins, with additional wax injection inside box sections and cavities.

Which Panels on the Relay Are Treated?

On the Citroen Relay, the main outer body panels — including the sides, sliding door, rear doors and roof — are made from galvanised steel. Structural elements like the sills, cross-members and chassis rails also benefit from anti-corrosion treatment, though the level and consistency of this protection improved noticeably with the third-generation model launched in 2006. Cavity wax is applied to hidden box sections during production, and the underside receives a sprayed sealant coat. However, aftermarket bulkheads, ply lining and shelving that trap moisture against bare metal can undo a lot of that good work over time.

Corrosion Protection Across Citroen Relay Generations

The Relay has been on sale in the UK since 1994, and the level of rust protection has improved significantly across its three main generations. Understanding which era of Relay you're looking at is key to knowing what corrosion risks to expect.

Older Relay Models (Pre-2006) and Rust Hotspots

First and second-generation Relays (built between 1994 and 2006) used less galvanised steel than later models and were assembled with production techniques that left more seams and pockets where moisture could collect. Common rust issues on these vans include the front wings just above the wheel arch, the lower doors, the sills where they meet the wheel arches, and the rear cross-member behind the bumper. Rear wheel arches on high-mileage examples can rot from the inside out, particularly if the van has been used for building work with damp materials sitting in the load bay. These vans can still be excellent workhorses, but a thorough underside inspection is essential.

Third-Generation Relay (2006 Onwards) Improvements

The current-generation Relay, launched in 2006 and updated in 2014 and 2019, benefits from a fully galvanised outer body, improved cavity protection and better factory seam sealing. Rust is much less of an issue on these vans, though the same problem areas — sills, wheel arches, and the rear cross-member — should still be inspected on higher-mileage examples, especially those that have spent years on gritted UK roads. Overall, a well-maintained third-generation Relay can comfortably reach 200,000 miles without significant corrosion showing on the bodywork.

2004 Citroen Relay LWB Dimensions and Bodywork Notes

A 2004 Citroen Relay LWB (long-wheelbase) is a second-generation model, and its bodywork protection reflects the standards of that era. The LWB version typically offered a load length of around 3.2 metres, a load width of approximately 1.87 metres (about 1.42 metres between the wheel arches) and a load volume in the region of 10 to 11 cubic metres, depending on roof height. Overall vehicle length is around 5.4 metres.

From a corrosion perspective, a 2004 LWB Relay will have some galvanised outer panels but nothing like the coverage of the post-2006 model. Buyers looking at one of these today — two decades on — should expect to find some rust, particularly around the rear wheel arches, the tailgate lip and the sills. Many will also have had aftermarket ply lining fitted, which is worth lifting to check for corrosion on the load floor and lower side panels.

Citroen Panel Van Relay 1500 TD HDi MWB Key Points and Body Protection

The Citroen Relay 1500 TD HDi MWB (medium-wheelbase) refers to the payload-focused variant of the second-generation Relay, typically fitted with the 2.0 or 2.2 HDi turbo-diesel engine and rated to carry around 1,500 kg. As an MWB, it offered a shorter load length than the LWB — usually around 2.85 metres — but a similar load width and side door opening.

Bodywork protection on the 1500 TD HDi MWB is broadly the same as other second-generation Relays: partial galvanisation on outer panels, underbody sealant from the factory and cavity wax on the main structural sections. These vans were popular with tradespeople and couriers, so many examples have led hard lives. Focus your inspection on the load area — particularly where shelving brackets have been bolted through the floor or sides, as these are classic rust entry points. The rear cross-member and rear wheel arches deserve extra attention on any HDi Relay of this age.

Common Rust Areas to Inspect on a Used Citroen Relay

No matter which generation you're considering, there are a handful of areas where Relays consistently show corrosion first. Knowing where to look will save you from an expensive surprise.

Sills, Wheel Arches and Rear Cross-Member

The sills — the structural sections beneath the doors — are a classic Relay rust point, particularly at the front where they meet the wheel arch and at the rear where they tie into the sill's inner section. Wheel arches, especially at the rear, can rot from the inside where road spray sits against the metal. The rear cross-member (the horizontal beam behind the rear bumper that the towbar mounts to) is another well-known weak spot; on older Relays it can rust through completely and become an MOT failure. Get underneath with a torch and look for scaling, bubbling paint and any areas where the underseal has flaked away.

Door Bottoms and Load Area Floor

The bottoms of the rear barn doors and the sliding side door can trap water inside if the drain holes are blocked, leading to rust from the inside out. The load area floor is another common problem area, especially on vans that have been used to carry damp or corrosive materials such as sand, plaster or building rubble. If ply lining is fitted, try to lift a section or shine a torch behind it — any orange staining or soft, flaky metal is a warning sign.

How to Keep Your Citroen Relay Van Rust-Free

Even a well-galvanised van benefits from a bit of preventative care, particularly in the UK where winter road salt is a constant threat. Wash your Relay regularly through the salt-heavy months, paying particular attention to the underside, wheel arches and sills. Many owners get their vans steam-cleaned underneath once or twice a year, followed by a fresh application of underbody wax or a proprietary rust inhibitor.

Keep drain holes in the doors clear, check that any load area modifications — bulkheads, shelving, ply lining — aren't trapping moisture against the metalwork, and touch up stone chips promptly before they can spread. If you're keeping the van long-term, a professional cavity wax treatment every few years is worth considering; it's not expensive and can add many years to the life of the bodywork. Finally, try to park under cover where possible, or at least somewhere with good drainage so the underside isn't sitting in a puddle overnight.

Buying a Used Citroen Relay: What to Check Before You Commit

When viewing a used Relay, take a magnet with you — it won't stick to filler, so it's a quick way to spot bodged repairs. Inspect the van in daylight, ideally when it's dry, and get down on your knees to check the sills, wheel arches, cross-members and door bottoms. Open the bonnet and look at the inner wings and the top of the strut towers; on higher-mileage examples these can show corrosion too.

Ask the seller for the service history, and note whether the van has been used for particularly harsh work — heavy building materials, coastal deliveries, or years of gritted-road commercial use will all accelerate wear on the bodywork. A pre-purchase inspection from an independent commercial vehicle specialist is money well spent on any Relay over five or six years old. Get those checks right, and a Citroen Relay's galvanised bodywork will reward you with many years of dependable service.

FAQs

Are Citroen Relay vans galvanised, and how well are they protected against rust?
Yes, Citroen Relay vans use galvanised steel for their outer body panels, with the level and quality of protection improving significantly on the third-generation model launched in 2006. Structural sections receive cavity wax and the underside is sprayed with a protective sealant at the factory. Rust protection is generally very good on modern Relays, but older pre-2006 models can show corrosion on sills, wheel arches and the rear cross-member, particularly if used on salted UK roads.

Do Citroen Relays rust badly?
Modern Relays (2006 onwards) do not rust badly and can comfortably cover 200,000 miles without significant bodywork corrosion. Older Relays are more prone to rust, especially around the rear wheel arches, sills, door bottoms and the rear cross-member behind the bumper. Regular washing, keeping door drain holes clear and applying underbody wax will all extend the life of the bodywork considerably.

Is the Citroen Relay chassis galvanised?
The Relay's main chassis and structural sections are treated with anti-corrosion coatings and cavity wax rather than being fully hot-dip galvanised in the way the outer body panels are. This is standard practice across the van industry. The treatment is effective, but the chassis should still be inspected for rust on any used Relay, particularly around the rear cross-member and suspension mounting points.

How long do Citroen Relay vans last before rust becomes an issue?
A well-maintained third-generation Relay can go 15 years or more before rust becomes a significant concern, provided it's washed regularly and any stone chips are touched up promptly. Older second-generation Relays typically start showing rust from around 10 years old, often at the rear wheel arches and cross-member. Cavity wax treatment and regular underside cleaning can extend the bodywork's life substantially.

What year did Citroen start galvanising the Relay properly?
The most significant improvement in the Relay's corrosion protection came with the third-generation model launched in 2006, which introduced fully galvanised outer body panels, better cavity protection and improved factory seam sealing. Further refinements were made in the 2014 facelift and again with the 2019 update, so newer Relays have progressively better rust resistance than earlier examples.
