What Commercial Steel Work Does Sullivan Steel Do?

Sullivan Steel handles every type of commercial steel work in Ireland — new commercial buildings, steel extensions on existing premises, commercial refurbishments, retrofits, bespoke fabrication, architectural metalwork and structural alterations. Where industrial work is about operational efficiency, commercial work often combines function with appearance — buildings that need to perform AND look the part. We work across retail, hospitality, office, mixed-use, healthcare, and bespoke commercial projects, with the full scope handled by one team from our Wexford base. Most commercial projects take 4–10 months from quote to completion depending on scale and refurbishment complexity.

Why Choose Sullivan Steel for Commercial Steel Projects

Commercial steel work covers a wider range than agricultural or industrial — from a small steel extension on a retail unit to a complete commercial refurbishment, from a one-off architectural feature to a full new commercial build. Here's what makes Sullivan Steel different:

Full scope across commercial projects. We handle new commercial steel buildings, steel-frame extensions, refurbishments and retrofits, bespoke metalwork, structural alterations and repairs. One contractor, the full range — not a specialist in one corner of commercial work.

In-house fabrication for custom commercial work. Commercial projects almost always involve custom features — bespoke door frames, architectural details, integration with existing structures. Our Wexford workshop fabricates to spec, so we're not constrained by what's available in standard kits.

Industrial-grade quality, commercial finish. We build commercial buildings to the same structural standards as industrial work — fully certified, properly engineered, compliance-ready — but with the finish quality commercial clients expect. Cleaner lines, better detailing, finishes that hold up to commercial environments.

Extensions and integration expertise. Adding steel to an existing commercial building isn't the same as building new. Matching profiles, integrating with existing structures, working around live business operations — we do this regularly and bring the right approach.

Refurbishment specialists. Most steel contractors only sell new builds. We re-clad, re-roof, repair and modernise existing commercial buildings — extending working life rather than demolishing and rebuilding.

Local team, national reach. Yard in Ballingly, Wellingtonbridge — real address, real team. We work across Ireland on commercial projects of the right scale.

Commercial Steel Building Services in Ireland

Sullivan Steel handles a wide range of commercial steel work — from full new builds down to bespoke metalwork features:

New commercial buildings. Retail units, hospitality premises, office buildings, mixed-use developments, healthcare facilities. Full structural steel and cladding, built to commercial regulations with proper certification.

Steel extensions. Adding steel-frame extensions to existing commercial buildings — increasing capacity, adding floors, extending footprints. Integrated with existing structures, matched to existing finishes where required.

Commercial refurbishments. Stripping back tired commercial premises and rebuilding to current standards — new cladding, new doors, new structural reinforcement, new finishes. Often cheaper than demolition and new build.

Retrofits and conversions. Converting commercial buildings to new uses — warehouse to retail, office to mixed-use, agricultural to commercial. Structural alterations, new openings, internal restructuring.

Bespoke architectural metalwork. Staircases, balustrades, custom features, architectural detailing. Where commercial premises need something specific that's not off-the-shelf.

Structural alterations and repairs. Replacing failed structural members, adding capacity to existing frames, reinforcing for new loading, fixing structural issues in older commercial buildings.

Re-cladding and re-roofing. Updating tired commercial cladding, replacing failed roofing systems, upgrading thermal performance. See our re-roofing and re-cladding service page.

Custom doors, frames and shopfronts. Bespoke steel doorways, shopfront frames, security shutters integrated with cladding systems.

Steel Extensions for Commercial Buildings

Commercial extensions are one of our most common project types. A business outgrows its premises — needs more storage, more retail space, more office, more production area — but moving isn't viable. A steel-frame extension is usually the answer.

Why steel extensions work for commercial buildings:

• Faster than traditional builds. Steel frames go up in days, not weeks. Less disruption to ongoing business.
• Designed to integrate. We can match profiles, finishes and structural details to existing buildings so the extension looks like part of the original.
• Flexible spans and heights. Steel allows wider spans than block-and-beam, opening up the layout possibilities.
• Cost-effective vs alternatives. Usually cheaper than concrete or traditional construction for the same footprint.
• Future-proof. Steel extensions are easy to modify, extend further or refit in the future.

What we handle on commercial extensions:

• Structural connection to existing building
• New foundations and base where required
• Steel frame fabrication and erection
• Cladding matched to existing finishes
• Doors, windows and openings
• Roof integration with existing roof system
• Internal finishing as part of scope or coordinated with other trades

If you're looking at extending a commercial building, the earlier we're involved the better — we can advise on what's possible, what's practical, and what the realistic budget should be.

Commercial Building Refurbishments

Older commercial buildings are often structurally fine but cosmetically dated, thermally inefficient or no longer fit for purpose. Demolishing and rebuilding isn't always the right answer — refurbishment usually is.

Common commercial refurbishment work:

• Re-cladding to update appearance and improve thermal performance
• Re-roofing to extend working life by 30+ years
• Internal restructuring for new uses or layouts
• Adding mezzanines, storage, or partitions to maximise usable space
• Structural reinforcement for new operations or heavier loads
• Updated doors, windows and openings for modern requirements
• Compliance upgrades for fire safety, accessibility, energy performance

A proper refurbishment typically costs 40–60% of new build for the same square footage, takes significantly less time, and avoids the planning, demolition and waste issues of replacement.

Our Commercial Steel Project Process

Every commercial steel project follows the same structured approach:

1. Site visit and consultation. We come to the site, understand the project — new build, extension, refurbishment, alteration — and look at the constraints and opportunities.

2. Engineering and design coordination. Commercial work typically needs architects, structural engineers, and possibly other consultants. We coordinate at design stage to avoid expensive surprises.

3. Detailed written quote. Steel spec, cladding, doors, integration with existing structures (where applicable), exclusions, timeline. All in writing.

4. Planning and compliance. Commercial projects typically need full planning permission, fire safety certification, disability access certification, BCAR documentation. We work alongside your planning consultant.

5. Fabrication. Steel components, custom features, architectural metalwork — all fabricated in our Wexford workshop to your spec.

6. Site preparation. Foundations, service connections, working around live operations if the existing building is occupied.

7. Erection, cladding and finishing. The visible build — frame, cladding, doors, finishes. For occupied commercial premises, we plan around operational requirements.

8. Final inspection, certification and handover. Walkthrough, snag list, all structural and compliance documentation provided.

Commercial Steel Work Across Ireland

For commercial steel buildings in Ireland, we work nationwide. The scale of commercial projects typically justifies the travel — Dublin, Cork, Galway, Limerick, the midlands, anywhere across Ireland.

Most of our smaller commercial work (extensions, refurbishments, bespoke metalwork) stays in the South East — Wexford, Waterford, Wicklow, Carlow, Kilkenny, South Tipperary — because the economics work better. For larger commercial new builds and significant refurbishments, we travel.

If you're not sure whether we cover your area, ring us.

Frequently Asked Questions

Q: Can you add a steel extension to my existing commercial building? Yes — commercial steel extensions are one of our most common project types. We handle structural connection to existing buildings, matched cladding profiles, integration with existing roof systems, and the planning and compliance work that goes with extensions.

Q: Do you handle commercial refurbishments? Yes. We re-clad, re-roof, restructure and modernise commercial buildings across Ireland. Most steel contractors only sell new builds — we specifically handle restoration work because it's usually the right answer for buildings that are structurally sound but cosmetically or thermally dated.

Q: How long does a commercial steel project take? Depends on scope. A simple commercial extension 8–16 weeks. A full new commercial building 6–10 months. Commercial refurbishments 4–8 months. Bespoke metalwork or smaller alterations 2–6 weeks. All times include planning permission where required.

Q: Do I need planning permission for a commercial steel extension? Almost always yes. Commercial extensions don't qualify for the exempted development rules that apply to agricultural buildings. You'll need full planning permission, fire safety certification, and BCAR documentation. See our planning permission guide for context.

Q: Can you build bespoke architectural metalwork? Yes — bespoke staircases, balustrades, custom door frames, architectural features, shopfront elements. We fabricate to spec in our Wexford workshop, so we can produce custom designs that standard suppliers can't.

Q: Can you work on commercial buildings while they're still in use? Often yes — though we'll discuss the practicalities with you upfront. For occupied commercial premises, we plan the work around business operations, with phased approaches where needed.
