The Biohort AvantGarde Steel Shed (A8) XXL is one of the strongest, most modern, and the best quality metal sheds available today. It is a top quality product made from hot-dipped galvanised, polyamid coated steel plate which is double the thickness of cheaper products. High level skylight windows are fitted to the front of the building, and they sit directly under a functional roof overhang which provides additional protection from the rain. All screws, bolts and hinges are made from high quality stainless steel, and the steel doors are secured with a twist grip cylinder lock and 3-point locking system. A spare key is supplied as standard. The Biohort AvantGarde (A8) is approximately 8'x12' and comes in 3 colours (Dark Grey, Quartz Grey or Silver), with a choice of single or double doors. Currently they come complete with FREE shelves, gas-spring dampener, integrated guttering, tool holders and a 20-year warranty!
