Steelwork, Roofing & Construction in the Garden Route
Professional steelwork, roof structures, welding, sheeting, concrete work, 3D modelling and general contracting across George and the Garden Route.
Professional Contracting & Fabrication Solutions
Tarkka Projects delivers reliable, high-spec fabrication and contracting solutions across George, Mossel Bay, Knysna, and the broader Garden Route region.
Rather than functioning solely as a mobile welding service, we oversee projects through every critical phase. From initial 3D planning and precise steel detailing in our workshop to poured concrete bases, precision roof sheeting, and long-term facility upkeep, our team provides single-source accountability.
Turnkey Project Delivery
Every build adheres to rigorous structural safety standards, giving developers, commercial operators, and residential clients an organized partner on site.
- 3D structural modeling and engineering planning
- Workshop steel fabrication and coded welding
- Concrete foundations, plinths, and civil bases
- Industrial roof sheeting and site installation
- Routine preventative maintenance and structural repairs
Disciplines built for structural endurance.
Full-lifecycle industrial fabrication and site erection across George, Mossel Bay, and the Garden Route. Every discipline is engineered in-house from digital drafting to completed installation.
Fabrication and erection of heavy load-bearing frames, portal structures, and industrial trusses.
Engineered metal sheeting, standing seam systems, flashing, and weather-tight coastal cladding.
Coded welding, bespoke metalwork assemblies, access staircases, gates, and plate components.
Engineered foundations, reinforced floor slabs, retainers, and turnkey industrial builds.
Corrosion management, structural reinforcement, routine re-roofing, and industrial repairs.
Precise structural drafting, detail verification, and clash detection prior to fabrication cuts.
From Concept to Completion
Every build follows a connected sequence. We manage each stage under one roof so your structural tolerances, schedules, and quality hold true from first drawing to final sign-off.
Planning
Site feasibility evaluations, engineering briefs, and project timeline setup tailored to Garden Route site constraints.
3D Modelling
Full CAD drafting and structural modeling to verify every joint, clearance tolerance, and connection detail before steel cutting.
Fabrication
In-shop structural steelwork cutting, certified welding, and anti-corrosive coating applied under controlled workshop conditions.
Construction
Earthworks coordination, precision concrete footing pours, and anchor bolt setting ready to receive the fabricated frame.
Installation
Crane staging, on-site structural erection, purlin framing, and weather-tight roofing and sheeting installation across the frame.
Maintenance
Scheduled structural audits, seam fastening inspections, and coastal corrosion protection to keep structural envelopes sound.
Consolidating design, off-site fabrication, and site construction under a single master contractor eliminates inter-trade friction, controls timeline tolerances, and delivers cohesive execution. By managing every weld, footing, and sheet ourselves across George and the Garden Route, we remove communication gaps between separate sub-contractors and keep accountability direct.

View All ProjectsWhy choose us
We take on full structural execution across the Garden Route, coordinating fabrication, concrete, and roofing without trade handoffs.
Every assembly complies with strict fabrication standards and structural tolerances. We specify durable, heavy-gauge materials that withstand harsh coastal weathering without premature fatigue.
Steelwork, metal roof sheeting, concrete foundations, and civil finishes remain under single-point site supervision. You bypass sub-trade friction, schedule lapses, and conflicting handovers.
We resolve difficult terrain, complex loading criteria, and architectural steel geometry directly on site. Detailed pre-build planning ensures components fit cleanly without field improvisation.
Our crews deploy across George, Mossel Bay, Knysna, and Plettenberg Bay with dependable staging. We understand marine corrosion, salt spray, and localized wind loads specific to the coast.
Regional coverage: George, Mossel Bay, Wilderness, Sedgefield, Knysna, Plettenberg Bay.
Serving the Garden Route
Full-lifecycle steelwork, roofing installation, and turnkey construction. Our mobile rigging and erection crews operate continuously along the N2 arterial corridor from Mossel Bay through Plettenberg Bay.
Regular contracting operations deployed across residential coastal builds, light industrial developments, and commercial agricultural properties. We manage heavy site deliveries, crane positioning, and municipal structural inspections across all six regional municipal districts.
Direct Site Inspections
We conduct on-site dimension verification, 3D laser scanning, and ground-level foundation assessments before initiating steel fabrication.
Typical Workload: Heavy steel framing, industrial roofing, fabrication facilities
