All fences, gates and tree guards are made using mild steel. Tree guards and gates are made in our workshop. Fence components are made in our workshop, installed in the field and then welded together on site. We will make and supply all types of gate and tree guard, however we do not supply fence components for self erection. Derwent Valley Forge will install your fence to ensure it is done to the highest standard in keeping with our unique fence design. We install estate fencing in the York area and all around the country.
