GREEN’S RADIATOR SERVICE: Built on Quality, Forged in Family

For more than a century, Green’s Radiator Service has been a name synonymous with quality, reliability, and passion. Established in 1921, the business has quietly become one of South Africa’s great industrial success stories — family-owned, proudly local, and delivering excellence into key industries like mining, locomotive, and power generation. Today, under the stewardship of fourth-generation Director Bradley Green, Green’s is preparing for an exciting new phase of growth as it completes a major expansion and doubles down on its reputation for best-in-class service and product quality.

ENGINEERED TO LAST

The Green family story is remarkable. The company’s roots go back to a bold adventure and a young man’s search for opportunity.

“The company was started by my great-grandfather in 1921. He was an orphan and a stow away, living in America and Australia for some time. He learned how to solder while abroad and, in his late teens, he came back to South Africa and he started soldering radiators. He learnt as he went and began repairing radiators as a business, opening Green’s 104 years ago. By 1930, he had built his own radiator from the ground up,” Bradley Green tells Enterprise Africa.

From those humble beginnings, Green’s Radiator Service has grown into a vital supplier to some of the most demanding industrial clients in South Africa and beyond. The company now employs 85 people and continues to evolve its services, spanning design, manufacture, service and repair of radiators, oil coolers, intercoolers, charge coolers, and other heat exchangers.

“We specialise in design, manufacture, service, and repair of radiators, oil coolers, intercoolers, charge coolers, or any heat exchanger and associated components. We have a full scope, and we do all design and manufacturing in house. We don’t import and bring in anything, we try to do everything ourselves,” says Green.

The company’s ability to adapt, while remaining true to its roots, has helped maintain a strong footing across generations. Green himself entered the business with a technical background, ensuring the practical experience remained alive in leadership.

“My grandfather always told me to do whatever I wanted to do as long as I got a trade, so I did my apprenticeship with Porsche. When he passed, I realised that I wanted to be a part of the family business. There is no way my father would’ve taken me into the business straight from school as that would have been easy. When I joined, I spent five or six years in the workshop itself and I was running machinery every day, learning about how every nut, bolt and washer worked in every single process. That has put me in a good position now because I understand the business inside out.”

CULTURE OF QUALITY

In the modern era of price-driven procurement and squeezed margins, Green’s has never been interested in being the cheapest supplier. The business has always been about delivering exceptional quality — products that work first time, every time — and building customer relationships that last.

“Our big focus is maintaining a level of quality that exceeds what anyone else can do. Profit is important, but doing the right things first means that everything else will follow. We always focus on using the correct materials, doing design briefs correctly, getting things signed off correctly – not just profit,” says Green.

That ethos runs throughout the business, from factory floor to director’s desk. It’s a mindset that has built a strong culture of pride and loyalty, not only among customers but also among staff.

“We have a very low staff turnover, and we have people who have been here for 30, 40, and 50 years. That says a lot about how we run the business and the type of people we are,” he says.

“Bing Haynes started working for Green’s when he was 14 years old. He is now 87. He is still here, and we are very happy to have him around.”

Customers, especially in mining and locomotive industries, have come to rely on Green’s for more than just quality components. The company handles complete projects, end-to-end, in-house.

“We do everything ourselves from procurement to design to manufacture to sale to aftersales service and repair – we don’t outsource anything.

“We have a team of workshop managers who are responsible for handling projects from start to finish. They create relationships and understand the markets, and they bring in jobs which will sit with a single team from inception to completion. We have very strict quality standards, and all jobs are pressure tested, pulse tested, cycle tested, and everything is documented with conformity certificates. Our standards are very stringent, and we take quality very seriously. The result is that our reputation precedes us. We want the best quality and design that you can pay for. We don’t want to be the cheapest.”

Green’s client list reads like a who’s who of major industry players — long-standing partnerships that have been earned through decades of consistent delivery.

“We have been on contract with Thungela and Seriti and all of the big mining houses for the best part of 40 years. That is performance-based meaning if you perform you keep the contract, if you don’t then you lose the contract. We still have those contracts in place and that speaks for itself.”

EXPANSION & EVOLUTION

Now, as demand continues to grow — particularly in the genset market driven by loadshedding in South Africa — Green’s has invested heavily in a physical expansion, adding capacity and capability.

“We have just expanded. We bought the property next door to us which is 3700 sq ft and we have put in overhead cranes, spray booths and test bars. We have a whole warehousing section, and we are 99% complete with that expansion,” Green reveals.

“The challenge in most businesses is managing people, whether that is staff or customers. People are always the biggest unknown. Any challenges that we have faced are managing expectations and people. We are a very service driven business. If the phone rings more than three times, we get in trouble – we are customer and service based. Going to nth degree to do whatever we can to maintain that and instilling that mentality in staff has always been a bit of a challenge, but we manage to stay on top of it.”

In particular, the genset side of the business has seen surging demand as South African businesses and infrastructure owners look to stabilise power supply.

“A large portion of our growth was due to loadshedding with panic and pandemonium around gensets. Our genset business has, for the last three years, been very good. We are a big player in the mining and locomotive sectors, and it has been a positive time.”

That positive trajectory is rooted in a willingness to invest and to innovate — a defining feature of Green’s approach to long-term business building.

“We are in a unique position being a fourth-generation family business – most do not make it that far. We are extremely proud of that, and the driving force of the Green family is massive. Many family businesses become complacent and go with the motions, but we have put a lot of effort into innovation and keeping things fresh. That is why we have completed the expansion – we’re always looking at ways to improve and streamline so things flow in a better way. The result has been that year-on-year our results are always up.”

DRIVING FORWARD

With new workshop space, upgraded infrastructure, and a team that bleeds quality and service, Green’s Radiator Service is in pole position for the future. The business may be over a century old, but it feels far from dated — innovation, family values, and engineering excellence are fuelling the next chapter.

“We always say ‘you’re only as good as your last job’ and we know that one bad project could spoil everything we have worked for.”

“We have exceptional pride in what we do. We are in that rare position to have a generational family business that is still dedicated and excited about what we do. The responsibility of upholding an institution to the standard it has been accustomed to is the primary focus. That goes above and beyond anything. Money is a product of what we do but it is not why we do what we do.”

In an age where businesses fight for survival, Green’s is doing what it has always done — standing tall, soldering excellence into every product, and keeping South Africa’s industrial engines running strong.
