Welding & Metalwork in South Africa: Gates, Burglar Bars & Repairs

From burglar bars and driveway gates to trailer repairs and steel staircases, a good welder or boilermaker makes homes safer and fixes what's broken. This guide covers what to look for and how custom metalwork is priced.

What jobs do welders and metalworkers do?

Metalwork covers a wide range. Common residential and small-business jobs include:

• Security: burglar bars, security gates, window guards, palisade fencing, spike-topped walls.
• Access: driveway gates (swing and sliding), pedestrian gates, and automation brackets.
• Structural: steel staircases, balustrades, carports, patio and shade structures, lintels.
• Repairs: cracked gates, broken hinges, trailers, tow bars, farm equipment and gates.
• Custom fabrication: braai stands, furniture frames, signage, brackets and bespoke pieces.

Welders may specialise. A boilermaker or structural welder handles heavy steel; a general fabricator does gates and burglar bars; some focus on stainless steel or aluminium and ornamental work.

When do I need a professional welder?

Any load-bearing, security or safety item should be done by a skilled welder — a weak weld on a gate, staircase or carport can fail dangerously. You also need a pro when work must match existing steel, when precise measurements matter (a gate that must fit an opening), or when the piece will be automated. For structural steel that supports a roof or floor, an engineer's sign-off may be required. Small cosmetic repairs might tempt a DIY approach, but security and structural work is not the place to cut corners.

What should I check before hiring?

• Experience and examples of similar past work (photos of gates, bars, structures).
• The type of welding they do (MIG, TIG, arc/stick) and whether it suits your material.
• Whether they can work with your metal — mild steel, stainless, aluminium or wrought iron.
• References from previous clients, ideally nearby.
• Whether they do site work or fabricate off-site and install.
• Public liability insurance, given the fire and grinding risks of on-site work.
• A clear, written, itemised quote.

Ask to see finished work in person if you can. Neat, consistent welds, proper alignment and a good paint or galvanised finish signal quality.

How does quoting for custom metalwork work?

Custom pieces are quoted per job, not off a price list, because they depend on your design, dimensions and material. A proper quote should break down: materials (type and gauge of steel, quantity), fabrication labour, finishing (primer, paint, powder-coating or galvanising), transport, and installation. Expect the welder to measure the opening or space in person, or ask for accurate dimensions, before pricing.

Always get the quote in writing, confirm what the finish includes, and agree on a deposit structure. For gates and larger jobs, a deposit for materials is normal; avoid paying the full amount before installation. Clarify lead time, as custom fabrication takes days to weeks.

What about finishing and rust protection?

South Africa's climate, especially near the coast, is hard on steel. Finish determines how long the work lasts. Basic mild steel needs primer plus enamel paint and periodic maintenance. Galvanising (hot-dip or electro) and powder-coating last far longer and resist rust better, which matters for gates and outdoor structures. Stainless steel and aluminium avoid rust but cost more. Ask what's included: a cheap quote may skip proper prep and finishing, meaning rust within a year or two. Coastal residents should prioritise galvanised or coated finishes.

How do I make sure security work is actually secure?

For burglar bars and gates, the strength is in the design and the fixing, not just the welds. Ask about the gauge (thickness) of the steel and bar spacing, how the item is anchored to the wall or frame, and whether it meets your insurer's requirements. Some home insurance policies specify burglar bars or gates on certain openings, so check your policy before deciding on a spec. For automated gates, confirm the fabricator coordinates with the gate-motor installer so brackets and weight suit the motor.

What it typically costs

Ranges reflect the 2026 South African market and vary by size, steel gauge, finish and area. Custom work is quoted per job. These are indicative, not fixed.

• Burglar bars (per standard window): R700–R2,500 supplied and fitted.
• Steel security gate (pedestrian/door): R1,500–R5,000+.
• Sliding driveway gate (excl. motor): R6,000–R25,000+ depending on size and design.
• Swing driveway gate: R4,000–R15,000+.
• Palisade fencing: R450–R1,200 per metre supplied and installed.
• Carport (single steel): R8,000–R20,000+.
• General repairs / small welding jobs: R350–R1,500 plus call-out.
• Call-out fee: R150–R500.

Powder-coating or galvanising, ornamental designs and stainless steel add cost.

Frequently asked questions

How long does a custom gate take? Typically one to three weeks from deposit to installation, depending on design, finish and the welder's workload.

Should I choose galvanised, powder-coated or painted steel? Galvanising and powder-coating last longest and resist rust — worth it for gates and coastal areas. Paint is cheaper but needs upkeep.

Do I need engineer sign-off? For load-bearing structural steel (roofs, mezzanines, some staircases) you may. Gates and burglar bars usually don't, but confirm for structural work.

Can a welder come to my home? Yes for repairs and installation. Larger custom items are usually fabricated off-site and installed on-site.

What deposit is reasonable? A materials deposit (often 50%) is normal for custom work. Avoid paying in full before the item is installed and inspected.

Key takeaways

• Use a skilled welder for anything security-related, load-bearing or automated.
• Check experience, welding type, insurance and photos of past work.
• Custom pieces are quoted per job — insist on an itemised written quote.
• Finish matters: galvanising or powder-coating resists SA's rust, especially at the coast.
• Confirm steel gauge, anchoring and your insurer's requirements for security work; pay deposits, not full amounts, upfront.
