ACM is the best material for high-visibility signs. The material you choose affects the longevity of the signs as well as their visibility, which is crucial for safety and compliance with regulations. Many sign experts recommend ACM due to its superior performance. While plastic signs are still utilised in certain areas, both ACM and plastic are common materials for traffic signs. Sin embargo, ACM signs offer greater visibility. Those looking for traffic signs for sale often select ACM because clear visibility is paramount.

En Optraffic, we understand the importance of visibility and durability in traffic signage. That’s why we offer a range of high-quality letreros de tráfico for sale designed to meet the highest standards of safety and performance. Explore our selection today to ensure your signage stands out and remains effective for years to come.

Visibilidad

Daylight Performance

How well a sign can be seen in the day is very important. The material you pick changes how long the sign keeps its colour and how clear it looks in the sun. ACM is good at not fading or getting damaged by weather. Dibond, which is a type of ACM, keeps its colour and shape for five to ten years, even outside in tough weather. This makes ACM a good choice for signs that need to last a long time outdoors.

Plastic signs like Coroplast are light and cheap. But these signs lose their colour and break down faster in the sun. Coroplast signs start to fade and wear out much sooner than ACM signs. Sintra Board is another kind of plastic sign. It lasts longer than Coroplast but does not keep its colour as well as ACM. If you want a sign to stay bright and easy to see for a long time, ACM is better than plastic.

Nota: If you add a UV gloss coating to ACM traffic signs for sale, they can handle sunlight even better and stay bright for many years.

Night-Time Reflectivity

It is very important for traffic signs to be seen at night. Both ACM and plastic signs can have reflective vinyl added to help drivers see them in the dark. The kind of reflective sheeting put on the sign helps people see it better at night.

Traffic signs must follow strict rules for how well they reflect light. En Australia, rules like ALS 1742 y Como/nzs 1906 say traffic signs for sale must use retroreflective materials except for black parts. Other countries have rules too, like ASTM and EN, for reflective sheeting. ACM signs are flat and strong, so it is easy to put good reflective sheeting on them. This helps people see the signs from far away, Incluso por la noche o en mal tiempo.

Plastic signs can also have reflective coatings, but they are mostly used for short-term or less important signs. Signs that need to last a long time on roads are usually made from ACM or aluminium to meet safety rules. Different grades of reflective sheeting, like Engineer Grade or Diamond Grade, are often put on ACM signs to make sure they are easy to see.

Consejo: For important road signs, always make sure the traffic signs for sale have the right reflective sheeting and meet the rules for being seen.

Durabilidad

Weather Resistance

Weather resistance is very important for outdoor signs. Signs outside face rain, wind, nieve, and strong sun. The material you pick changes how long the sign lasts. It also affects how well the colours stay bright. ACM signs are made from two thin aluminium sheets and a plastic core. These signs are very good at handling bad weather. They can last more than 20 years with little care. Laminated prints on ACM signs stay bright for 4 o 5 años. They do not fade quickly. The aluminium top layer keeps out UV rays, agua, y óxido. You only need water and mild soap to clean them. This keeps the signs looking new. You can add special coatings to make them even stronger.

Plastic signs are usually made from PVC or similar stuff. These signs do not last as long outside. Most plastic signs fade, grieta, or peel after 18 a 36 months. Sunlight breaks down the colours in the plastic. This makes the colours fade faster. Hot and cold weather and storms make this happen even quicker. Plastic signs may look nice at first. But they lose their good look much sooner than ACM signs.

Nota: In places near the sea, ACM signs do not rust from saltwater. This makes them great for highways and roads by the beach.

Impact Strength

Impact strength means how well a sign can take a hit. This could be from flying sticks or someone bumping into it. ACM signs are strong because of the aluminium and plastic core. This mix helps the sign stand up to bumps and knocks. The aluminium layers help the sign keep its shape. They also protect the printed part.

Plastic signs have different impact strength. Some plastics are hard but can snap easily. Others bend more but might not break. This means some plastic signs can crack if hit. Others might just bend. But ACM signs are usually better at stopping damage. The aluminium top helps protect them. On busy roads or places with lots of cars, ACM signs last longer.

Consejo: If you want traffic signs for sale that last, handle weather, and are tough, ACM is the best choice for most outdoor signs.

ACM Performance

Structure and Benefits

ACM is a great choice for signs you need to see easily. It has two thin aluminium sheets stuck to a plastic core. This makes the panel light but also strong. Many signs use ACM because it mixes the good parts of aluminium and plastic. The aluminium has a special coating that keeps the sign safe from bad weather. This coating also helps the sign look new for longer. ACM signs look like normal aluminium signs, so they work well for any project.

ACM has lots of good points for making signs. You can cut and shape the panels easily. This means designers can make many kinds of signs. ACM is light, so it is easy to move and put up. Big signs can use ACM because it does not bend easily. When you add High Intensity Prismatic Reflective sheeting, the sign is easier to see. This sheeting meets important rules for road and safety signs. That is why many road signs use ACM. ACM is one of the top materials for outdoor signs that need to be strong.

• ACM has two thin aluminium sheets and a plastic core.
• The aluminium has a special polyester coating.
• ACM signs are light and strong.
• The panels are easy to change for different signs.

Environmental Resistance

ACM signs are very good at handling tough weather. The aluminium on top keeps out rain, sun, and wind. Many signs get a lot of sun, but ACM keeps its colour and shape. The polyester coating stops the sign from fading or rusting. ACM signs last for years, even near the sea where there is salty air. The plastic core makes the sign even stronger, so it does not crack or bend. Lots of signs on busy roads use ACM because it stays bright and easy to read. ACM signs work well in every season. They last a long time, so they are a smart pick for anyone who needs signs that last.

Consejo: You only need water and mild soap to clean ACM signs and keep them looking good.

Plastic Signs

Typical Uses

Plastic signs are used in many places. People pick them for jobs that do not last long. In busy work areas, almacenes, and offices, plastic signs help give warnings and directions. Many workplaces use plastic signs for safety, como “Precaución: Wet Floor” o “Salida”. These signs are light, so workers can move them easily. Plastic sign frames and composite materials are strong and do not rust. This makes them good for wet places.

Plastic signs are good for events and building sites. Event organisers use them to guide people or show where not to go. Building teams use plastic signs for road closures or warning about dangers. Plastic signs can bend to fit curved places, which helps in crowded spots. Acrylic and PETG plastics have different levels of clearness and strength. This means signs can be made for what each place needs. Plastic signs last up to two years outside if the weather is not too harsh. This makes them a smart choice for short jobs.

• Indoor safety signs: warnings, information, and directions in offices, almacenes, and factories.
• Temporary outdoor signs: building sites, eventos, and work areas.
• Flexible signs: fit curved places in busy spots.
• Cheap signs: easy to put up and swap.

Nota: Plastic signs are best when you need to put them up and take them down quickly.

Limitations

Plastic signs have some problems outside. They can fade, bend, or twist in strong sun, wind, o lluvia. Con el tiempo, the colours on plastic signs may not stay bright. This makes them harder to see. In bad weather, plastic signs might not keep their shape or stay put. Workers may need to fix the signs more often.

The table below shows how plastic signs and ACM compare:

Plastic signs are easy to use and cheap, but you may need to replace them after a few years. ACM signs stay strong and easy to see for much longer. For traffic signs for sale that need to last outside, ACM is usually the best choice.

Best Material for Traffic Signs for Sale

High-Speed Zones

Signs on fast roads must be seen from far away. The right material helps keep people safe. Experts pick aluminium composite material (ACM) with Class 1W reflective sheeting for these signs. This sheeting is very bright and works from many angles. Drivers can see these signs early, Incluso por la noche o en mal tiempo. Class 1W sheeting follows strict Australian rules like AS/NZS 1906.1 and ALS 1742. Well-known brands like Avery Dennison and 3M make these strong materials.

Highway signs use ACM or galvanised steel. These materials do not rust and handle tough weather. Signs stay strong and clear for many years. Installers put these signs on strong posts or breakaway systems. This keeps the signs steady in wind and rain. Microprismatic retroreflective sheeting, like the T-11500 Series OmniCube, gives the best visibility for guide signs. The T-7500 and T-6500 series also shine brightly and last a long time. These features make ACM the best choice for traffic signs for sale on fast roads.

Consejo: Always check that traffic signs for sale meet the right rules for being seen and lasting a long time before you buy them.

Critical Control Signs

Critical control signs warn drivers about dangers or changes ahead. These signs must always be easy to see. For these signs, ACM with top reflective sheeting is the best choice. This keeps the signs bright and clear, día o noche. Emergency signs, speed limits, and road closure signs all need to be seen easily.

Both cities and country areas use ACM for these important signs. En las ciudades, signs face pollution and lots of cars. In the country, signs face strong sun and storms. ACM does not rust or fade quickly. Reflective sheeting helps the signs stay bright, even when it is dark. Plastic signs can be used for short times, but ACM is better for signs that need to last.

When picking traffic signs for sale, buyers should choose the right material for the job. Signs in busy or risky places need ACM with good reflective sheeting. This makes sure the signs are easy to see and follow all safety rules.

Installation and Handling

Weight Considerations

Weight plays a big role in how easy it is to install and handle traffic signs for sale. ACM signs use two thin sheets of aluminium with a plastic core. This design makes the signs light but strong. Each square metre of ACM weighs about 3.5 a 5.5 kilograms. Workers can carry these signs without much effort. The lightness of ACM comes from the polyethylene core, which keeps the signs easy to move while still giving them the strength of aluminium. Compared to solid aluminium, ACM signs weigh about half as much. This means installers can lift, carry, and position the signs with less strain. The reduced weight also helps lower labour costs and makes transport simpler. Plastic signs are also light, but ACM signs offer a better mix of strength and low weight. The light weight of ACM signs makes them a top choice for large outdoor signs and busy roads.

Mounting Systems

Mounting systems for ACM and plastic signs give installers many options. Cold mounting uses pressure-sensitive adhesives. Installers clean the surface with isopropyl alcohol, then press the signs into place. The adhesive gets stronger over time, reaching full strength in about 24 horas. This method works well for smooth surfaces and quick jobs. Mechanical mounting uses aluminium strips and VHB tape with screws. Installers attach strips to the edges of the signs, then use screws to hold everything tight. This method lets the signs flex a little, which helps keep them in place. For seamless looks, full frames or flex face systems can hide the joins between signs. Some jobs use pressure-sensitive tape for temporary signs or to hold parts while the adhesive cures. Mechanical mounting takes more time because it needs careful screw placement and sometimes extra bracing behind the signs. Both ACM and plastic signs work with these systems, but ACM signs stay flat and strong, making them easier to mount on posts, walls, or frames. Good mounting keeps the signs safe and easy to see in all weather.

Consejo: Always check that the mounting system matches the size and weight of the traffic signs for sale for the best results.

Rentabilidad

Initial Cost

When choosing materials for signs, many buyers look at the price first. Plastic signs usually cost less than ACM signs at the start. This lower price makes plastic signs a popular choice for short-term use. Event organisers, construction teams, and schools often pick plastic signs for temporary needs. Plastic emergency warning triangles and traffic signs offer reflective visibility at a lower price. Their lightweight build and easy moulding allow for many shapes and bright colours. These features help plastic signs stand out, even in busy areas.

Conos de tráfico de plástico also show how cost-effective plastic can be. They are light, easy to move, and quick to set up. People use them for emergencies, minor repairs, o eventos. Their bright colours and reflective strips make them safe, Incluso por la noche. Bulk buying lowers the price even more. Plastic cones work well in parking lots, calles residenciales, and places with little space. For projects that do not need heavy-duty signs, plastic is a smart, affordable option.

Nota: Plastic signs are best for short-term, low-traffic, or space-limited projects where budget matters most.

Long-Term Value

ACM signs cost more at first, but they give better value over time. These signs last much longer than plastic signs. ACM signs resist fading, agrietamiento, and weather damage. Esto significa menos reemplazos y menos mantenimiento. On busy roads, carreteras, and in harsh weather, ACM signs stay clear and easy to read for years. Their strong build keeps them in place, even in storms or high winds.

Plastic signs may need replacing after a year or two, especially outdoors. This can make them more expensive in the long run. ACM signs, por otro lado, often last over a decade. Their durability saves money on repairs and replacements. For permanent or high-visibility needs, ACM signs offer the best long-term value.

Consejo: For projects where signs must last and stay bright, ACM signs are the best investment.

Impacto ambiental

Recyclability

Recycling is important for signs. Many signs use plastics like PET, HDPE, CLORURO DE POLIVINILO, LDPE, PP, and PS. Each plastic type has its own recycling rules. Some plastics are easy to recycle. Others can be bad for the environment. The table below lists common plastics in signs and their recycling notes:

ACM signs have aluminium and a plastic core. Many recycling centres take aluminium, so the metal layers in ACM signs can be recycled. The plastic core might not be recycled, but the aluminium means less waste. ACM signs last longer, so fewer signs go to landfill.

Consejo: Always check your local recycling rules before throwing away signs. Some centres take certain plastics, but others do not.

Production and Safety

Making and getting rid of signs can affect people and nature. Workers need to be careful with some materials. Por ejemplo, PVC and polystyrene can let off dangerous chemicals if burned or left outside. Signs made from safer plastics like PET and HDPE are less risky.

When recycling or throwing away signs, safety is important. Only trained people should handle dangerous materials. Signs with special coatings or old materials may need extra care. Workers should wear gloves, goggles, and protective clothes when handling some signs. Proper disposal stops bad chemicals from getting into the air or water.

Some recycling uses heat or chemicals to break down materials. High heat can turn dangerous fibres into safe glass or ceramic. These ways help cut down on waste and make recycling safer. Recycling signs means less rubbish in landfill and helps the environment.

Nota: Picking signs made from recyclable materials helps keep people and nature safe. Safe recycling and disposal make communities cleaner and healthier.

ACM is the top pick for traffic signs for sale you need to see well. The aluminium layers help the colours stay bright and easy to spot. Aluminium does not rust or fade, so signs last longer outside. Good visibility on roads helps keep people safe. Aluminium lets you add reflective sheeting, so signs are clear at night. ACM signs stay strong even in bad weather because of the aluminium. People should pick ACM with good aluminium for signs that stay bright. If you need more help, talk to a trusted supplier or check your local rules for traffic sign visibility.
