Projecting signs play a crucial role in business visibility, helping shops, cafes and offices attract attention from passing foot traffic. Unlike flat fascia signs, projecting signs extend outwards from a building, making them more noticeable from multiple angles. This makes them a popular choice for businesses in busy streets and shopping areas.
Choosing the best material for projecting signs is essential for durability, aesthetics and long-term cost-effectiveness. Factors such as weather resistance, weight and maintenance impact the final decision. In this guide, we’ll explore the most reliable materials for projecting signs, helping you select the best option for your business needs.
Factors to Consider When Choosing a Material
Selecting the best material for projecting signs involves balancing durability, aesthetics, cost and maintenance. The right choice ensures longevity while maintaining a professional appearance. Below are the key factors to consider when deciding on the most suitable material.
Weather Resistance
Projecting signs are constantly exposed to the elements, so the material must withstand rain, wind and UV exposure. Metals like aluminium and stainless steel are corrosion-resistant, making them ideal for long-term outdoor use. Acrylic and polycarbonate also hold up well in varying weather conditions, though they may require UV-resistant coatings to prevent fading. Wooden signs, while visually appealing, need regular sealing to avoid warping and rotting in damp conditions.
Durability & Maintenance
A sign’s lifespan depends on the strength of the material and the level of upkeep it requires. Dibond (aluminium composite) is highly durable and resistant to rust and weather damage, making it a low-maintenance option. Stainless steel offers exceptional longevity but may need occasional polishing to maintain its appearance. Acrylic is durable but can scratch easily, requiring careful cleaning. If maintenance is a concern, choosing a material with minimal upkeep will save costs in the long run.
Weight & Installation
The weight of a sign affects its installation and structural support. Heavier materials like stainless steel require strong mounting brackets, increasing installation costs. Lighter materials such as aluminium and acrylic are easier to install and put less strain on walls or poles. Polycarbonate, being both lightweight and impact-resistant, is a good choice for areas prone to strong winds.
Customisation & Aesthetics
Branding is a key consideration when selecting a material. Acrylic and polycarbonate offer high-quality finishes and allow for illuminated designs, making them ideal for modern retail stores. Wood provides a classic, handcrafted look suited to boutique shops and heritage buildings. Dibond can be printed with detailed graphics, making it a versatile option for businesses seeking a polished appearance.
Cost-effectiveness
While stainless steel and solid wood offer premium aesthetics, they come with higher costs. Aluminium composite materials (Dibond) provide a balance between durability and affordability. Acrylic and polycarbonate are cost-effective for illuminated signage but may need protective treatments to extend their lifespan. Businesses should weigh the initial investment against long-term durability to ensure the best return on investment.
By considering these factors, businesses can choose the best material for projecting signs that meets both practical and aesthetic needs while ensuring longevity and cost-efficiency.
