Convex safety mirrors eliminate dangerous blind spots at road junctions, car park exits, warehouse corners, and tight access lanes. By presenting a wide-angle, curved reflection of the surrounding area, they allow drivers and pedestrians to detect approaching hazards before entering or crossing a potential conflict zone. Our range spans compact indoor units through to large-diameter outdoor highway mirrors, all manufactured to resist UV degradation, vandalism, and the full range of British weather.
Designed for exposed roadside use, outdoor convex mirrors are manufactured from polycarbonate or acrylic with a UV-stabilised anti-fog backing. They are mounted on adjustable wall brackets or post systems to optimise the viewing angle for specific junctions. Applications include:
Lightweight indoor mirrors are used wherever pedestrians and vehicles or materials-handling equipment share space. Available with wall-mount, ceiling-mount, and corner-mount configurations:
Full-dome mirrors provide a 360° view of the surrounding area and are ceiling-mounted at intersections where vision is needed in all directions simultaneously. Quarter-dome and half-dome variants suit corner-mounted applications. Ideal for:
For applications where vandalism, harsh chemicals, or extreme temperatures are a concern, stainless steel convex mirrors offer unmatched durability. The slight colour tint inherent in stainless steel has no meaningful impact on detection at typical installation distances. Preferred for:
As a general rule, use the largest mirror that is practical for the mounting location. Larger mirrors provide greater detection distance and wider coverage. For outdoor road junctions, a minimum 600 mm diameter mirror is recommended. Warehouse intersections with forklift traffic benefit from 600–800 mm units. Full-dome ceiling mirrors for multi-directional coverage should be at least 800 mm in diameter to provide reliable detection at aisle widths of 3 m or more. Height of installation is equally important — a mirror mounted too high or too low relative to the driver's eye line reduces effectiveness significantly.
For a car park exit onto a road where the driver's view is restricted to 10–15 metres, a 600 mm mirror is typically adequate. If the sight-line restriction extends to 20–30 metres — common at junctions with walls or hedges — a 800 mm or 1,000 mm mirror is recommended. Larger mirrors provide greater detection distance but must be positioned so the centre of the mirror is at the driver's eye line (approximately 1.0–1.2 m above the road surface for the seated driver of a typical car).
Quality outdoor convex mirrors use polycarbonate or acrylic lenses with an anti-fog backing treatment. Under normal UK conditions, condensation and light frost do not significantly impair visibility. In persistently cold or very damp locations, heated mirror options are available. Avoid siting mirrors where shade and poor air circulation cause persistent condensation. Regular cleaning with a soft cloth and mild detergent removes road grime that reduces reflectivity over time.
Convex mirrors are a recognised engineering control for blind junction hazards and are referenced in HSE guidance. However, for high-risk traffic movements (e.g. heavy goods vehicles in dense pedestrian areas), mirrors alone may be insufficient — a formal traffic management risk assessment may indicate the need for additional controls such as banksmen, traffic lights, or physical segregation. A mirror is a useful supplementary measure in most cases.
Convex mirrors on the public highway require the approval of the local highways authority as they constitute roadside furniture that may distract or be confused with official signs. Many authorities will approve mirrors at private accesses as a condition of planning permission or highway agreement. On private land, no such approval is needed, though you should ensure the mirror does not itself create a hazard by redirecting glare or distracting drivers on the adjacent public road.
As a general guide, convex mirrors should be mounted so the centre of the mirror is at approximately 2.0–2.4 metres above ground level for vehicle use in car parks and entrances, allowing both car drivers and pedestrians to be clearly visible. For pedestrian-only areas, a lower mounting height of 1.5–1.8m may be more effective. Always carry out a site-specific sightline test after installation to confirm full coverage of the required viewing area.
Convex mirrors typically provide a wide-angle field of view of between 90° and 180° depending on the mirror diameter and convexity. Larger diameter mirrors (600mm–800mm) provide a wider effective viewing range and greater visibility at longer distances. The trade-off with a wider angle is a smaller apparent image size — for close-range applications (internal junctions, blind corners), a deeper convex curve is preferred.
Yes. We offer convex mirrors suitable for both indoor and outdoor use. Outdoor mirrors are manufactured with UV-stabilised, weatherproof acrylic or polycarbonate mirror faces and galvanised or powder-coated steel frames rated for exterior exposure. Indoor mirrors may use standard acrylic. Always check the IP rating or outdoor suitability of the specific mirror before purchasing for external use in the UK climate.
Our acrylic and polycarbonate mirror faces are significantly more impact-resistant than glass alternatives and will not shatter if struck, making them a safer and more vandal-resistant choice. For high-risk environments, we recommend stainless steel convex mirrors which offer the highest level of vandal resistance, being virtually impossible to break or deface permanently. Dome-shaped security mirrors in ceiling mount formats also present a less targetable profile.
Mirror diameter selection depends on the viewing distance required. As a general rule: 300mm mirrors are suitable for viewing distances up to 5 metres (small rooms, tight corridors); 450mm mirrors cover up to 8 metres; 600mm mirrors are effective to around 12 metres; and 800mm+ mirrors are suited to car park entrances and wide junctions up to 15–20 metres. For outdoor road use, 600mm–1000mm mirrors are most common. Our team can advise on the right size for your specific site.
Clean acrylic and polycarbonate mirror faces with a soft, damp cloth and mild soapy water — avoid abrasive cleaners, solvents, or scouring pads which can scratch the surface. For stainless steel mirrors, use a stainless-specific cleaner applied in the direction of the grain. Periodically check and tighten the mounting bracket and adjust the viewing angle if the mirror has shifted. Remove any grease, bird droppings, or heavy soiling promptly as these can etch the surface if left.
