The advantages of Clear Span Shelters over conventional shedding are: Low Cost Clear Span Shelters are a low cost alternative when considering shedding, especially when labour in construction is considered. Good Ventilation Clear Span Shelter's design is both wide and has a high ceiling, so it picks up the slightest air movement, keeping the shelter cool. Side and end wall vents can be customized to suit. In longer shelters optional off-set tie down rail brackets can be used to create a 50cm horizontal vent between the cover and wall. Corrosion Resistant Clear Span Shelters are made from an ultraviolet stabilised polyethylene fabric stretched over a galvanised steel frame. Welded components of the Clear Span frame have been hot dip galvanised, making the entire structure highly corrosion resistant. Easy to Construct Clear Span Shelters do not require expensive skilled labour to construct. Comprehensive easy to follow instructions come with the shelter kit. Once foundation posts have been set in place, the frame and polyethylene covering of the shelter can be assembled in about a day. This ease of assembly makes the structures semi-portable. Easy to Move Clear Span Shelters are also easy to dismantle, and reassemble, making them ideal for temporary shelter. Versatility Clear Span's strong frame, high ceiling and easy doorway access make it a very versatile shed for many applications. Australian Made Clear Span Shelters are 100% Australian made, and suit Australian conditions. Our company is the only licenced manufacturer of this design (known as Bio Tech in North America) of shelter in Australasia; be wary of unauthorised copies.
