Sign Materials Guide: Choosing PVC, ALCOM, Correx or Vinyl

Choosing the right sign material starts with where the sign will be used and how long it needs to last. For facilities teams, the decision often comes down to rigid PVC, aluminium composite (ALCOM), Correx or self-adhesive vinyl. Each offers a different format for communicating safety information, directing visitors or labelling equipment.

This sign materials guide compares the options available from Viking Signs and explains what to consider before ordering. Material availability varies by product, so always check the individual product page.

How to choose the right sign material

Before comparing signage materials, consider the conditions at the installation point:

• Location: will the sign be indoors or outdoors?
• Wear: is it in a busy corridor, near machinery or in a quiet area?
• Environment: will it be exposed to moisture, dirt or regular cleaning?
• Duration: is the message temporary or intended to stay in place?
• Surface and fixing: do you need a rigid sign or a self-adhesive label?

These questions help narrow down the options before you compare the purchase price. For demanding or outdoor locations, ask our team to recommend a material for your site's conditions.

Sign materials compared: PVC, ALCOM, Correx and vinyl

PVC: rigid plastic signs

Our PVC signs are available in 1mm and 3mm options, depending on the product. Rigid PVC is an option for indoor corridors and doors, particularly where you want a rigid sign rather than a sticker. Selected recycling-sector products also offer a recycled 3mm PVC option.

ALCOM: aluminium composite signs

ALCOM is our aluminium composite option, available in 3mm with matt laminate and reflective options on selected products. Consider it when you need a more robust rigid sign. For high-traffic areas, we recommend rigid PVC or aluminium composite rather than stickers to help withstand knocks and cleaning.

Correx: lightweight fluted plastic signs

Our 5mm Correx is a lightweight fluted plastic option, well suited to temporary messages and budget-conscious uses. It is worth considering when the information is short-term rather than choosing solely on the lowest initial price for a permanent installation.

Vinyl and high-tack vinyl: self-adhesive labels

Vinyl and high-tack vinyl provide self-adhesive options for labels and smooth surfaces. They are useful formats for machinery, equipment and control panels. Browse our machine labels to explore the available options, and check that the chosen product suits your application surface.

Other signage options

Photoluminescent options are available on selected fire safety products. Magnetic options are also available where listed on individual products. Check the product details rather than assuming every design is available in every material or finish.

Should you choose a rigid sign or a sticker?

Choose the format around the installation point. Rigid plastic and aluminium composite signs are our recommendation for high-traffic areas where knocks and cleaning are a consideration. Self-adhesive vinyl is a useful option for labelling smooth, clean surfaces.

If you are unsure which format suits a particular surface, speak to our team before ordering. The right choice depends on the location as well as the message on the sign.

Choose your sign size and fixings

Our standard sizes range from 100 x 100mm to 900 x 900mm, with A5 to A1 formats and corner-hole options on many signs. Sizes and fixing options depend on the product. Browse our safety signs and wayfinding signs to compare the options for your site.

Compare whole-life cost, not just purchase price

Think about how often a sign may need replacing, not just what it costs to buy. Choosing a material that suits the location can help avoid unnecessary replacements and waste. We produce on demand in the UK and minimise offcuts. Read about our "Green because it's Lean" approach on our sustainability page.

Quick guide to choosing signage materials

• High-traffic indoor corridors and doors: consider rigid PVC or ALCOM.
• Temporary or short-term messages: consider Correx or lighter plastic options.
• Machinery, equipment and control panels: explore vinyl and high-tack vinyl labels.
• Demanding or outdoor locations: ask our team for a recommendation based on your site.
