A truck sun visor is a rigid panel mounted to the outside of the cab roof, above the windscreen. It projects forward from the roofline and casts a shadow over the glass — this is not the flip-down visor found inside a passenger car. If you are looking for an interior car visor, this page is not for you. This article covers exterior cab-mounted visors for professional trucks: the type fitted to Scania, Volvo, DAF, MAN, Mercedes-Benz, and Renault cabs by drivers who spend full shifts behind the wheel in Nordic conditions.
RST-Steel stocks 43 sun visors for trucks across all major truck brands — one of the widest ranges available in the Nordic market. The range covers Scania NextGen in the greatest depth, followed by Volvo FH, with additional coverage for DAF, MAN, Mercedes-Benz, and Renault. RST-Steel ships across Finland, Sweden, and Norway and installs at its own locations. What follows explains how these products work, what they are made from, how to match the right one to a specific cab, and what professional installation involves.
How Truck Sun Visors Block Glare and Protect Visibility
Truck cabs sit 2 to 3 metres above road level. At that height, the sun angle in spring and autumn at Nordic latitudes creates sustained, low-angle glare across the full width of the windscreen, often for 4 to 6 hours of a 10-hour shift in March or October. Passenger car drivers are largely unaffected at the same time of day because their eye line is lower. A truck driver cannot escape this through posture or position.
The internal flip-down visor blocks a section of the driver’s forward view when deployed. It can manage extreme sun angles briefly but is not a practical solution for sustained glare: blocking road visibility is not an acceptable trade-off. An exterior sun visor for a truck intercepts direct sunlight before it reaches the glass. The driver’s view is unobstructed. The visor does the work structurally, not by covering part of the windscreen.
The practical effect on driver performance is direct. Sustained glare causes eye fatigue, which increases reaction time and reduces hazard perception. At 90 km/h, even a 200 ms increase in reaction time adds approximately 5 metres to stopping distance. For fleet operators tracking driver health and incident data, a visor truck fitment is a low-cost structural intervention with a measurable effect on driver condition across a full shift.
Types of Sun Visors for Trucks
RST-Steel’s range includes three distinct product types. Each addresses glare reduction in a slightly different way, and the right choice depends on the cab, the operating environment, and the driver’s preference for projection depth and visual profile.
Standard Sun Visor
A flat or slightly curved panel running the full width of the cab above the windscreen, mounted via brackets to the cab roof. For Scania NextGen, this is available in 34 cm and 35 cm projection depths. The projection depth determines how much shadow is cast at different sun angles — a deeper projection shades more aggressively at higher sun angles. Both sizes address the primary problem of low-angle sun equally. This is the most common fitment for professional truck operators.
Eyebrow Visor
A narrower profile that sits closer to the windscreen frame. It has a lower aerodynamic footprint and less visual presence than a full-width visor. Suited to drivers or operators who want functional glare reduction without the full external shell appearance. RST-Steel stocks an eyebrow visor for Scania NextGen cabs fitted with Xenon or LED headlights.
Stoneguard and Windscreen Guard
A combination product that integrates a sun visor for trucks with a stone protection guard for the upper windscreen area. The lower portion of the product covers the upper area of the windscreen glass, protecting it from stone chips thrown up from the road. This is directly relevant for trucks operating on gravel roads, construction sites, and aggregate transport routes. RST-Steel stocks the Stoneguard Scania NextGen as a specific product in this category.
Materials and Construction: Steel vs. Other Options
External truck sun visors are manufactured in steel, fibreglass, or ABS plastic. Each material behaves differently in the conditions Nordic truck operators work in year-round.
Steel construction offers the highest resistance to physical impact, road debris, and temperature cycling. A steel visor does not deform in sustained cold, does not become brittle after years of UV exposure, and holds its mounting geometry reliably over time. Powder coating provides corrosion resistance against road salt, a relevant factor for any vehicle operating on treated roads from October through April. Steel products are heavier than plastic alternatives, but the weight difference at this scale has no meaningful effect on cab aerodynamics or fuel consumption.
Fibreglass and ABS plastic visors are lighter and can be shaped more precisely for cab-specific profiles. They are common in aftermarket fitment for cosmetic applications. For professional use in demanding operating environments, steel remains the more durable choice. RST-Steel manufactures its own steel accessories at its production facility in Nivala, Finland, and designs products specifically for Nordic operating conditions — the material selection reflects that context directly.
Matching the Right Visor to Your Cab Model
A sunvisor for a truck is not a universal product. The mounting geometry, roofline curve, and windscreen frame dimensions vary between manufacturers, between model generations from the same manufacturer, and sometimes between cab variants within the same generation. Ordering the wrong product means it will not fit correctly, and in some cases will not fit at all.
Scania
The Scania NextGen cab (introduced in 2017) has different mounting geometry from the pre-2017 Streamline and R-series. RST-Steel’s Scania sun visor range covers all current NextGen variants: P, G, R, S, and XT series. Products include the Fox Parts sun visor in 34 cm and 35 cm projection depths, an eyebrow visor for NextGen cabs with Xenon or LED headlights, a windscreen guard that combines sun visor function with stone chip protection for the upper windscreen area, and the Stoneguard Scania NextGen. Confirm whether the truck is a NextGen (2017+) or a previous-generation Streamline or R-series before ordering — the mounting geometry is not interchangeable.
Volvo
The Volvo sun visor range covers FH4, FH5 (FWC variant), and FH Aero. The FH Aero has a distinct roofline geometry from the standard FH — the Aero-specific product is dimensioned for that profile. Confirming whether a Volvo FH is a standard variant or an Aero before ordering is essential.
DAF, MAN, Mercedes-Benz, Renault
Products exist in the range for these brands. Coverage is narrower than the Scania and Volvo sub-ranges. The same principle applies: confirm the exact model and cab generation before selecting a product. The full truck sun visor range lists available options by brand and model.
Combining Sun Visors with Work Lights and Roof Bars
On many truck configurations, the cab roof carries more than one accessory. Roof bars, work light bars, and sun visors all occupy the same structural zone above the windscreen. The order and compatibility of these products matters for both fitment and function.
A sun visor mounted at the leading edge of the cab roof will partially shade the area immediately above the windscreen. Work lights or auxiliary driving lights mounted forward of the visor are unaffected. Lights mounted behind the visor on a roof bar may have their forward beam partially interrupted at steep downward angles — relevant for work lights aimed at the ground directly in front of the cab rather than auxiliary driving lights aimed at the road ahead.
RST-Steel supplies both sun visors and roof bar systems, and its installation teams work with combined configurations regularly. When ordering multiple roof-mounted accessories, specifying the full configuration at the point of order allows the installer to confirm compatibility and mounting sequence before the vehicle arrives. This avoids rework and ensures the final installation is clean and structurally sound.
Installation: What Professional Fitting Involves
External sun visors are mounted to the cab roof structure using bracket systems. On current Scania NextGen and Volvo FH variants, installation uses the factory-provided mounting positions on the cab — no drilling into the cab structure is required. On older models or some non-Scania/Volvo cabs, drilling may be necessary to create secure mounting points.
The installation process involves fitting the bracket to the cab roof, attaching the visor panel to the bracket, and verifying that the product sits level, secure, and correctly positioned relative to the windscreen frame. A visor that sits too far forward, too far back, or at an angle will not cast shadow in the intended pattern and may generate wind noise at highway speeds.
RST-Steel installs at its own locations in Pirkkala and Kempele in Finland, and ships products across Finland, Sweden, and Norway. For operators who want to confirm fitment for a specific cab before ordering, the contact page is the direct route to the team that handles this. Providing the truck model, cab variant, and year of manufacture gives the information needed to confirm the correct product and installation approach.
