																	The steel roof truss is one of structural engineering s most important and iconic elements. 
																	Step 2 build the roof truss. 
																	The span of the roof is what determines the size of the roof truss. 
																	Part of a truss that extends beyond its support exclusive of. 
															
													
									
	
		
	
																	Made of individual members with equal counteracting tensile and compressive forces its purpose is designed to behave as a single object which carries supports a load over a span. 
																	To build steel trusses from angle iron weld rivet or bolt angle iron pieces together. 
																	Begin by determining the measurements of the roof s slope. 
																	You need to measure the width of the roof area. 
															
													
									
	
		
	
																	This will be the rafters length. 
																	Step 3 attach the roof truss. 
																	Glue the plywood to the joint and then nail it to each member to fully secure it. 
																	Inclined or horizontal member that establishes the bottom of a truss usually carrying combined tension and bending stresses. 
															
													
									
	
		
	
																	Structural support usually a beam or wall that is designed by the building designer to carry the truss reaction loads to the foundation. 
																	Lay pieces of plywood over each joint covering about a foot 30 cm of each truss member s length. 
																	Cut it to the length you require and add the plumb cut to its ends.
