What is an Arrow Resin Series shed made of, and does it need painting?

The Resin Series is built from multi-wall resin panels on a frame, UV-protected and water-resistant, so the shed is all-weather: it does not rot, it cannot rust, and it never needs painting, staining or sealing. The resin holds its colour in the sun — Brown Ash, Ash Grey, Dark Ash and Ash White — and washes down with a garden hose. The door handles are pad-lockable (padlock not included), the walk-in sizes have a window and a high vented gable roof so air moves through, and everything in the box — panels, frame, floor, roof, hardware and instructions — goes together with ordinary hand tools.
