A conventional truss can come with either web or straight legs. These trusses are clear span and the purling material is generally 2×4 wood. These can be used in buildings up to 60′ wide.
The conventional truss has a variety of uses to include poultry houses, shop buildings, houses and churches.
*This truss is commonly the most economical as wood is used instead of metal for purling material.
