I need my order urgently, can I pay for faster shipping?
Yes. We offer an express delivery service which aims to deliver all orders in 1-3 working days. Orders are delivered by a recognised courier company and may require a signature on delivery.
Do you have a minimum order charge or small order fee?
This is a question we are asked fairly regularly due to the previlance of either a minimum order charge or small order fee within the industry.
At Simply Plastics our approach has always been to treat all orders equally, small or large. We want all customers, new and existing, to be able to place orders with us confident that they are only paying for the products and materials that they require. We therefore do not have a minimum order charge or small order fee.
How can I calculate the weight of a Polycarbonate Panel?
All of the different types of plastics that are available on our website, whether they be a panel, a disc, tube or rod, show the weight of the piece you require once you have entered your dimensions, shown in grams or kg.

The weight of any plastic can be calculated using the simple formula: Weight = Volume x Density
Read our blog post on how to calculate the weight of a variety of different plastics covering panels, discs, road and tube.
