Many people may think bolt together Lighting Truss is a hard thing,because they do not know how to do.Now,today I wanted to bring you this quick tip which to offers both aesthetic and safety improvements to the method I learned,include some Roof Truss Designs.


        The first step of putting together truss involves laying out the pieces you are going to bolt together, in the layout you desire.  This serves 2 important purposes. 1) You won't have to move it once it's one huge piece, or at least not far and 2) you can make the laces line up.The second step, you may move along to bolting/pinning/spigotting your truss together.  Bolts need to be grade 8 rated and meet the size recommended by your manufacturer(probably 15/16″).  All bolts in a span of truss must face the same direction, and truss uprights need to have the bolts on top, nuts on bottom.  When you are tightening the bolts, always wrench down with your ratchet from the nut side, and only turn a few cranks past firm.  If you over-tighten your bolts you risk damaging or even breaking them.


If you are using spigot or pin truss, you simple need to get everything lined up and the pins through so that the safety pins can be latched.  This may take a hammer.And also if you want know more about Lighting Truss,please go to RK web site:http://www.raykglobaltruss.com.there are have roof truss designs pictures,you can have a look.
