The Sheldon Shelter SPG323 is a large clear span external shelter with a goal post type central leg to allow a greater clear space underneath the shelter without the need for a central leg. The steel feet and central goal post supports the timber framework which hold up the timber crossbeams and the polycarbonate roofing system. The galvanised steel framework and legs can be left exposed or powder coated to any required RAL reference to match existing site colour schemes or styles. This shelter can also be extended on a modular based system and can be extended with continuation units until the desire length of shelter or area required has been achieved.
