What pushes the price of IBR carports up
- Thicker sheets such as 0.58 mm instead of 0.47 mm
- Chromadek or coastal-grade paint systems over plain galvanised
- Side panels, pitched A-frames and wider three-car spans
Types of IBR carports
| Type | Best for | Keep in mind |
|---|---|---|
| Flat IBR roof on four posts | Simple, affordable cover for one or two cars | Still needs a 5° fall for drainage |
| Pitched A-frame IBR | Matching a pitched house roof | Extra rafters add to the bill |
| IBR with side panels | Extra shelter from driving rain and wind | Closed sides can trigger full building plans |
| Cantilever IBR | Narrow driveways with posts on one side | Purlins sit closer, footings carry more load |
| Triple IBR carport | Three cars, bakkies or a trailer | Wide spans need careful purlin design |
IBR carport materials and specs compared
| Material | Strengths | Watch out for |
|---|---|---|
| Galvanised IBR sheet | Lowest cost, bright zinc finish | Can fall short in harsh conditions |
| Chromadek IBR sheet | Painted finish, 10 to 30 year warranties | Higher price than bare galvanised |
| Chromadek Ultim | Colour-coated grade made for coastal areas | Confirm the grade is on the quote |
| Zincalume (AZ150) | Aluminium-zinc coating on high-tensile steel | Warranty needs the specified fastener type |
| 0.47 mm vs 0.58 mm sheet | Thicker sheet allows wider purlin spacing | Thin sheet dents and flexes sooner |
Sheet thickness and profile
- IBR sheets come in roughly 0.40 mm up to 0.80 mm thick.
- Most carport quotes specify 0.47 mm, 0.50 mm or 0.58 mm.
- Profiles differ by maker, from 686 mm to 890 mm cover width.
- Ask which thickness is quoted, since thin sheet dents more easily.
Finish and rust protection
- Plain galvanised sheet carries a bare zinc coating with a metallic look.
- Chromadek adds an oven-cured paint layer over a galvanised core.
- Chromadek Ultim is the colour-coated grade aimed at coastal homes.
- Zincalume uses an aluminium-zinc coating, often AZ150 grade.
Pitch, purlins and fixing
- IBR needs a fall of at least 5° on runs under 30 m.
- Seal side and end laps when the roof pitch is low.
- Purlin spacing depends on sheet thickness, grade and local wind.
- Each screw needs a 26 mm bonded washer to stop leaks.
Approval for IBR carports
- An open-sided IBR carport of 40 m² or less counts as minor building work under SANS 10400.
- You still have to tell your municipality in writing before building, and it may ask for plans.
- Enclosed sides or a roof over 40 m² means full plans. Estates and body corporates can add their own rules.

Frequently asked questions
How much does an IBR carport cost in 2026?
Expect around R17 050 to R22 500 for a single and R26 400 to R34 800 for a two-car double of 6 × 6 m. Custom double builds can reach R65 000.
How long does a Chromadek IBR roof last?
Chromadek coatings are sold with 10, 20 or 30 year warranties depending on the grade. Ask which grade your installer is using.
Do I need plans for an IBR carport?
Not if it is open-sided and 40 m² or smaller, but you must notify the municipality in writing first. Bigger or enclosed builds need plans.
Is IBR better than a shade net carport?
IBR is a solid steel roof, so it blocks rain and hail that shade net lets through. It costs more, with shade net doubles starting near R10 450.
Can IBR sheets go on a nearly flat carport roof?
The roof still needs a fall of at least 5° so water drains off. On low pitches the sheet laps should be sealed.
