The Hartman Cast Aluminium Roma Pergola 3m x 3m is a square cast aluminium pergola which can be used with or without its retractable waterproof canopy & comes flat packed with all fixtures and fittings for home assembly. It is strong, durable, virtually maintenance-free, will not rust & the canopy can be used for shade (Ultraviolet Protection Factor of 50+) or to keep off the rain. Pergolas should only be used as a sunshade. The lining on all pergolas are waterproof however we do not recommend using them as a shelter from the rain they are by design a shading product only. Make sure all pergolas are fixed firmly to the ground or have a suitable weighted base to hold them in place. If not secured or weighted down they will move position if there is the slightest chance of wind. Please be aware that Pergolas/Pavilions are not permanent structures and we recommend removing the canopy between October and March. These are the months when the weather will cause damage to the fabric.Covering
