Why tough wiper blades matter
South African bakkie and SUV buyers want heavyduty options.
Synthetic materials and aerodynamics
Conventional passenger vehicle wiper blades aren ' t designed to deal with the corrosion and heat exposure of harsh African conditions. The traditional metal frame design of conventional wiper blades has a weakness because it is susceptible to corrosion.
Whether your vehicle is parked outside at a beach house for a few weekends a year, or exposed to freezing overnight conditions in the Kalahari or Eastern Cape highlands in winter, wiper blades with metal structures corrode.
The solution is to offer bakkie and adventure SUV customers upgraded wiper blades that feature a bracketless design. These wiper blades are designed without external moving parts, reducing potential points of failure and the number of parts susceptible to corrosion.
South Africa ' s longest family vacation period is over the warmest time of summer: the year-end December break into the following year ' s January. That means wherever South African bakkie or adventure SUV drivers travel with their families, the heat and radiation exposure on the vehicle ' s external components will be severe.
Many South African adventure vehicle owners choose to travel to Botswana, Mozambique and Namibia during the year-end vacation period. That means extreme UV radiation exposure for wiper blades. Natural rubber degrades rapidly with such intense heat exposure.
The abrasive properties of fine, extremely hard dust particles in the dirt-road driving environment, combined with heat-eroding and abrasive forces, rapidly ruin natural rubber wiper blades. Summer rainfall can also cause mud splatter, which can crust on wiper blades and lead to wear.
What double-cab bakkie and adventure SUV owners need are heavy-duty wiper blades made from materials that resist extreme heat degradation. That ' s where a selection of silicone or graphite-rubber wiper blades needs to be in stock for fitment centres that want to serve the adventure and 4x4 market.
The third technical feature that a heavy-duty aftermarket wiper blade needs is aerodynamics. Wiper blades with a wind spoiler prevent wiper shudder when driving into strong winds. That shudder is not only noisy and fatigue-inducing, but can also damage the windscreen over time.
Extreme wind conditions are a reality for South African double-cab bakkie and adventure SUV drivers. Anyone who has travelled in the late afternoon in the southwestern parts of South Africa and along the Namibian coastline during summer knows how extreme wiper blade shudder can become.
