Gas Cylinder Cage Installation Johannesburg exists because a cylinder standing loose against an external wall is a theft target and, in a complex or a commercial yard, a liability question. A cage solves both: cylinders secured, ventilated, protected from vehicle impact, and out of reach of anyone who should not be near them.
Gas Cylinder Cage Installation Johannesburg covers cages for single domestic cylinders through to multi-cylinder commercial banks.
Tell us how many cylinders, what size, and where they stand.

What a Cage Has to Do
- Ventilate. A cage is not a cupboard. It has to be open enough that any leak disperses at low level rather than accumulating, which is why solid enclosures are not used.
- Secure. Lockable, and fixed to the structure rather than merely standing there, since a cage that can be carried away with the cylinders inside is decorative.
- Restrain the cylinders. Upright and unable to topple.
- Keep clearances. The cage does not change the clearance requirements from windows, drains and boundaries. It has to sit in a compliant position, same as a bare cylinder.
- Allow exchange. A cage a delivery person cannot get a full 48kg cylinder into and out of will end up unlocked permanently.
Cage design is only half of it. If the cylinder position was not compliant before the cage went in, it is not compliant after. Get the position confirmed by the installer first.
Cage Costs
| Cage | Indicative supplied and installed | Notes |
|---|---|---|
| Single 9kg wall cage | R1,600 – R3,500 | Powder-coated steel, wall-fixed |
| Single 48kg cage | R3,500 – R7,000 | Floor-standing, bolted down |
| Twin 48kg cage | R5,500 – R11,000 | The common domestic size |
| Four-cylinder bank cage | R9,000 – R18,000 | Small commercial |
| Eight-cylinder bank cage | R16,000 – R34,000 | Restaurants, guest houses |
| Galvanised and coated upgrade | +15% – 30% | Worth it on exposed positions |
| Bollard protection | R1,800 – R5,500 | Where vehicles pass |
| Concrete plinth or slab | R2,500 – R8,000 | Where there is no firm base |
Cage prices vary widely by fabricator. Comparing three is worth the ten minutes.
Compare Cage Installation QuotesWeather and Finish
Inland air is kind to steelwork. A properly powder-coated mild steel cage lasts for years in Johannesburg, where the coastal argument for hot-dip galvanising simply does not apply. What shortens a cage here is summer hail stripping the coating and hard ultraviolet at altitude chalking it, both of which attack the finish rather than the metal. On open, unsheltered positions on the ridges around Northcliff and on the West Rand, galvanised and then coated is worth the premium. In a sheltered side passage the standard coated version is fine.
For Body Corporates and Managing Agents
Gas cylinders appearing on balconies one unit at a time is a recurring problem in Johannesburg complexes, and a per-unit cage arrangement in a designated position is the usual fix. Practical points when you scope it:
- Decide who owns the cage: the body corporate, or each owner
- Confirm the position works for delivery access, not just for looks
- Get one fabricator to price the whole scheme rather than each owner arranging their own
- Have the installations certified together, which is cheaper per unit than individually
- Write the cylinder position into the conduct rules so the balconies stay clear
Frequently Asked Questions
Is a gas cylinder cage required by law?
There is no blanket requirement for a domestic cylinder to be caged. Cylinders do have to be secured, upright, ventilated and in a compliant position, and in commercial and shared residential settings a cage is the practical way to achieve that plus security. Your installer will advise what your specific installation needs.
How much does a gas cylinder cage cost?
A single 48kg cage typically runs R3,500 to R7,000 supplied and installed, a twin R5,500 to R11,000, and a four-cylinder commercial bank cage R9,000 to R18,000. Galvanising on open, hail-exposed positions adds roughly 15 to 30 percent.
Can a gas cage be fully enclosed?
No. Ventilation is the point of the design. LPG is heavier than air, so a sealed enclosure lets a small leak accumulate at the bottom instead of dispersing. Cages are open mesh or louvred for that reason.
Can I build my own cylinder cage?
You can have one fabricated, but the cylinder position, clearances and connection remain the registered installer's call, and a cage that blocks ventilation or delivery access will have to be modified. Get the position signed off before anything is welded.
Does a cage affect my gas certificate?
Only in that the installation as a whole, including the cylinder position and its security, has to be compliant when the installer inspects it. A well-designed cage helps. A sealed box around the cylinders will be flagged.
What cage do restaurants need?
Most Johannesburg restaurants run a four to eight cylinder bank in a ventilated, lockable, bolted-down cage in the service yard, clear of extract discharge and vehicle routes, with bollards where delivery vehicles pass close.
