Polcore Mouldings

Mainline is the registered owner of the Polcore brand.

What is Polcore?

Polcore is a highly specified, extruded moulding made from recycled polystyrene and provides a durable, strong and environmentally friendly alternative to wood picture frame mouldings - 38% more carbon efficient in fact!

We are proud to offer a moulding product that protects the Earth's natural resources and commits to the 'reduce, reuse and recycle' philosophy.

Polcore mouldings look terrific, are economically priced and are available in over 1000 different designs and finishes.

Environmentally friendly

Made from a clean and waste free manufacturing process using solar and hydroelectric energy, Polcore is 80% to 95% recycled polystyrene. It is 100% recyclable and all Polcore mouldings are stamped to show their recycling status.

Easy to work with

Polcore can be cut easily and safely using a mitre guillotine and joined with softwood wedges and Polcore glue.

Beautiful to look at

Every Polcore moulding has a coating of High Impact Polystyrene creating a perfectly smooth surface for our stunning, 100% recyclable, decorative, high quality finishes.

Giving back

Mainline will be 30 years old in 2026! To celebrate this milestone, we have set a goal of reaching £50,000 in charity donations.

Previously, Mainline has been delighted to support regional, national and local charities including Ukraine Relief, the RNLI, Lincs & Notts Air Ambulance, Dove Cottage Day Hospice and Emmanuel House Nottingham.

We look forward to continuing to support charities through 2024 to achieve our birthday target.

Christmas 2023

For Christmas 2023 we chose to support Home-Start Newark. A donation was made in lieu of Christmas cards.

In their own words: "Home-Start is a local community network of trained volunteers and expert support helping families with young children through their challenging times. We are there for parents when they need us the most because childhood can’t wait. Home-Start works with families in communities right across the UK. No judgement, it is just compassionate, confidential help and expert support."

Last year Home-Start supported 78,900 children in 43,692 families, in communities across the UK.

Fantastic value on smaller orders

We are continually working to find ways of ensuring that our prices are amongst the most competitive. Our pack rate prices are available for orders of as little as 6 metres on many wood mouldings. This gives you access to some of the finest quality picture frame mouldings at the very best prices.
