BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a steel truss system and process for manufacture.
2. Description of Related Art
Many areas of the world often encounter severe weather systems such as hurricanes, monsoons, blizzards, tornadoes, thunderstorms, etc. These weather system generally leave a wake of disaster. Many homes, communities, towns, and villages have been devastated by severe weather storms. In addition, the people of these areas also are left without shelter of any kind. Many forms of rigid constructions have come about in order to provide temporary or permanent dwellings. Some of the more recognized examples follow.

SUMMARY OF THE INVENTION
Many natural disasters such as storm, hurricanes, tornadoes, earthquakes, etc. occur often without warning. Many buildings and dwellings suffer severe damage and destruction at the occurrence of the disasters. When these calamities happen, often people are left without adequate shelter. Likewise, there are areas in the world, with or without a disastrous calamity, that have people without shelter. There is a need to provide cost and time efficient building construction materials that can be quickly transported and erected within hours of a disaster or calamity.
Accordingly, it is a principal object of the invention to provide a cost and material efficient building truss.
It is another object of the invention to provide a cost and material efficient building truss that provides the maximum strength and versatility.
It is a further object of the invention to provide a prefabricated building truss having a square tubing and continuous round lattice webbing.
Still another object of the invention is to prefabricated building truss having a square tubing and continuous round lattice webbing that is light weight, easily transported and quickly erected.
It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.
