Gypsum Board Manufacturers in South Africa: Market and Plant Planning

Gypsum board manufacturers in South Africa include Saint-Gobain, through Gyproc, and Etex, which announced the purchase of Lafarge Gypsum South Africa in 2015. On 2023 trade data the country is a small net board exporter to its neighbors, yet about half its gypsum came from abroad on USGS’s latest figure. A new plant must solve rock, gas and competition first.

This is desk research from the public sources listed at the end, intended to help an investor or building-products group test the idea. South African public data are thinner than those for the Gulf, and we say so where we hit a gap. For method, see reading the gypsum board market.

Gypsum Board Manufacturers in South Africa: Who Is There

Here is what we could not establish. We found no public capacity figure for any South African board plant, and the Global Gypsum Top 50 table has no South African-based producer, because the leading firms are counted under their foreign parents. We also could not confirm exact board plant locations from open sources, or the current local position of other international brands. A feasibility study should obtain this from distributors and from the producers’ own sites, and should not rely on a report-site “market size”.

Note also what the bigger groups are doing. Saint-Gobain opened a fiber cement board plant in Ekurhuleni, Gauteng in January 2026 under a “Make it in Africa to Build Africa” strategy. So an incumbent is still investing locally, and in neighboring board types as well.

South Africa’s Gypsum Board Trade

WITS data for HS 6809.11, paper-faced plaster board, show a modest two-way trade in 2023.

The Saudi figure is credible, since Saudi Arabia reports about 9,569 t going the other way.

Converting tonnes to square meters

Conversion is tricky here because thin ceiling board is common.

Our 3,000,000 m² a year reference line (12 mm basis) makes about 27,000 t a year. That is more than all recorded imports in 2023, so taking every imported board would still not fill the line, and China and Saudi exporters would fight for those buyers.

So we would not call this an import-replacement story on current data. One year of data does not show a trend, however. Pull several years before concluding, since Saudi board entering the country shows that coastal buyers are willing to bring it in by sea.

The export side is more interesting. Zimbabwe, Zambia and Mozambique show an inland regional market served by road, in which South African producers already have an advantage. A new plant would have to take that share from them.

Gypsum Supply: Falling Local Output and Omani Rock

Here South Africa differs sharply from the Gulf. USGS reports the following.

USGS attributes the long decline to import competition. A 2024 North-West University MBA study describes local resources as depleting from the cement industry’s point of view, and it finds economic advantages in sourcing gypsum from Richards Bay.

For a plant, the numbers are striking. Our reference line needs about 25,000 t of pure gypsum a year, based on 7.0 kg of stucco per m². By our estimate, that is about 10% of the country’s 2022 mine output, or about 11% of 2023 imports. In most countries a line that size barely registers. Here it would be a noticeable buyer, competing with cement plants: USGS lists about 20.5 million t a year of cement capacity, running at about 12 million t.

This produces three supply options:

1. Local mines. The mines USGS names lie in the Northern and Western Cape, and they are tied to existing groups. Ask who would sell to a newcomer. Long road haul to Gauteng is likely to be expensive, so calculate it.
2. Imported rock through a port. Oman supplied about 93% of 2023 imports. Export sales there moved to a single state company from June 2026, and that company reports new African markets. Get a supply contract before fixing the site.
3. By-product gypsum. A wastewater specialist reported a 2020 pilot with a Highveld coal producer and said its process would extract about 100 kg/h of gypsum on a full-scale site. That is under 1,000 t a year by our estimate, far too small to feed a line today, but it is worth watching. Test any by-product against wallboard-grade expectations, as explained in natural vs synthetic gypsum.

The rock source largely decides the site. A coastal plant buys imported rock more cheaply but must reach inland customers, while a Gauteng plant does the reverse.

SANS Standards for Gypsum Board

South African National Standards are developed and sold by the South African Bureau of Standards. Gyproc names SANS 266 as the South African standard for gypsum boards, including performance requirements for moisture-resistant board. This is a gap in our research: SANS texts are paid documents and we could not open this one, so we give no numbers from it, and you should check the current edition.

Take these steps instead:

• Buy the current standard from SABS, and ask whether your board needs a mark or a test from a named laboratory.
• Ask three large contractors what their specifications say about board, since that can matter more than the standard itself.
• Compare the requirements against EN 520 and ASTM C1396, which are likely to matter for imported competition and export sales.
• Check fire rating claims and test evidence, particularly for Type X and fire-resistant boards.

Board Sizes and Products Sold in South Africa

Products shape the line specification, and the local market has features that the Gulf does not.

• Thin ceiling board. One South African builders’ merchant lists a Siniat 6.4 mm ceiling board at 900 mm × 4.2 m, weighing 19 kg, or about 5 kg/m² by our estimate. It is a single listing, but it raises an early design question.
• Fire board. Gyproc’s EPD notice covers 12.5 mm and 15 mm RhinoBoard FireStop, giving 11.71 kg/m² for the 15 mm product and 7.51 kg/m² for the 12.5 mm. Environmental declarations are now part of how the incumbent sells.
• Line width. Our reference line runs boards 1.2 m wide and 6–25 mm thick. Thickness fits, but a 900 mm product needs a different forming and cutting setup. State every target width in your requirement brief, and ask each supplier what changes. See gypsum board standard sizes.
• Thin board and throughput. Dryer loading and line speed vary with thickness, so a plant’s m² capacity at 6.4 mm is not its capacity at 12 mm. Ask for the figures at each thickness. Our drying process article explains why.

Gas, Power and Carbon Tax in South Africa

This may be the most important section for a new line. Our reference line burns 1.5–2.0 million m³ of natural gas a year and uses 1.4–1.8 million kWh of electricity.

The gas cliff. A 2026 article by a University of the Witwatersrand lecturer says the Pande-Temane fields in Mozambique have supplied roughly 90% of South Africa’s gas for two decades, and output will begin to fall after 2028. It cites a study calling for LNG terminals to be operational by mid-2030, and it says alternatives such as LPG, diesel or electricity could cost two to five times current gas prices. So do not assume a new pipeline connection will be secure for the plant’s life.

Practical response. Burners can be configured for other fuels, but each fuel changes storage and capital needs. Ask for dual-fuel options in the first quotation, with fuel consumption for each. A coastal site near a future LNG terminal may look different from an inland one, and that should feed into site selection.

Electricity. NERSA approved 8.76% for Eskom direct customers and 9.01% for municipal customers in 2026/27. The same article says sustained load-shedding has largely receded, but municipal network failures are now a less predictable risk. Dryers and calciners cope badly with sudden stops, so plan a safe shutdown sequence and consider backup power for critical drives. South Africa is listed at 230 V, 50 Hz, so frequency is not an issue.

Carbon tax. The same Witwatersrand article states that the effective rate rises from R35 per tonne in 2024 to R115 in 2030. Add the expected emissions from your fuel to the model.

A Go or No-Go Sequence for South Africa

Run these in order. Stop if one fails.

Build the numbers from your own quotations, using the framework in gypsum board plant cost. Regional exporters may also find a plant in a neighboring market more logical. Our note on gypsum board in Kenya shows how the same questions apply elsewhere in Africa.

FAQ

Who makes gypsum board in South Africa?

Saint-Gobain sells Gyproc and RhinoBoard products through its African business and mines gypsum in the Northern and Western Cape, while Etex announced the purchase of Lafarge Gypsum South Africa in 2015 to join Marley, and Siniat board is on sale locally. We could not confirm plant capacities or a complete list from open sources, so confirm any newer entrants with distributors.

Does South Africa produce its own gypsum?

Partly. USGS records 243,052 t mined in 2022, down from 558,242 t in 2012, and import dependence of 52% in 2019. Imports reached about 223,000 t in 2023, of which about 93% came from Oman. Other companies besides Saint-Gobain mine gypsum, including the cement producer PPC, so local supply exists, but buyers compete for it.

Is South Africa importing gypsum board?

Yes, but in modest amounts. It recorded about 20,900 t in 2023, almost entirely from China and Saudi Arabia, and it exported about 31,200 t, mainly to Zimbabwe, Zambia and Mozambique. Those imports are smaller than the annual output of even a 3,000,000 m² line. Check several years before assuming a trend.

Is natural gas a risk for a gypsum board plant in South Africa?

Yes. Pande-Temane, which has supplied about 90% of national gas, is expected to decline after 2028, and new LNG terminals are not yet secured. Since calcining and drying rely on heat, get a written supply offer and price a second fuel at the outset. Check also whether your site sits near a planned import route.

Which voltage does a gypsum board line use in South Africa?

South Africa is listed at 230 V and 50 Hz, which suits standard 50 Hz equipment. Confirm the connection voltage and capacity for your plot with Eskom or the municipality, since many industrial customers are supplied through municipalities. Our reference line has 600–800 kW installed. Plant-level reliability, including the local network, should be checked as closely as the national grid.

Planning a Gypsum Board Line for Southern Africa?

When rock, fuel and customers are confirmed, the gypsum board production line page shows the sections and consumption of our reference design, and the gypsum board plant setup guide covers the steps. YuxingCorp is a Singapore company that compares lines from vetted manufacturers in China. Import clearance, duties and local registration stay with the buyer.
