When Quality Matters

We have over 40 years experience in cutting expanded polystyrene. In this time we have developed special techniques to achieve a superior smooth face, and unlike most, we do not cut through the letter to remove centres; thus leaving the face free of lines and marks. We only use polystyrene containing a flame regarding additive for our letters. Where appropriate, we apply a special fire retarding substance to the polystyrene, which further increases its resistance to fire - and it also makes the letters much stronger. Learn more.

When Timing Matters

In recent years we have heavily invested in our infrastructure and installed advanced facilities for drying paint, glitter and other finishes, enabling us to reduce lead times on jobs. This, along with decades of experience dealing with nationwide, and international roll outs means when we give you a delivery date, we stick to it.

Even the very large letters stay relatively light - and can normally be easily handled by one person. ( some of the very large letters may need more than one).Polystyrene letters are an attractive option for most briefs as they are far lighter than metal or wooden letters of the same proportions.

Packing and Delivery

The packing and delivery method will vary depending on the size and style of the letters. In most cases the letters will be packed in the sheet that they are cut from. This keeps them very secure in transit. For some very large letters we may need to use a combination of polystyrene packing sheets, bubble wrap and cardboard. Being economic with materials is always on our mind, and we dont want you to have too much packing material to dispose of; however the most un-economical option is not enough packing, and the product damaged in transit.
