When you weigh up the problemsinvolved with hot rolled structural steel beams and engineered wood beams, LSB can providesignificant time and installation cost advantages.

2 The innovative, patented cold forming process givesLSB a unique profile with the torsional rigidity you would normally expect from hot rolled steel. It can be carried like a wood beam and can be cut, nailed,screwed, and drilled on site using the same tools you currently use. LSB is supplied with a G-60 orequivalent coating for superior corrosion with LSBLiteSteel beam is on average 40% lighter than hot rolled steel and engineered wood beams of equivalentperformance. It is easier to lift and carry and can behoisted without the need for a crane. Installing LSB doesnot require any new tools or radical building can install it and work with it like you would with awood beam. Fit the recommended saw blades, drill bits,screws, and nails and installation is easy. Connections towood components are simple using standard Simpsonor USP wood Construction can be used in place of other structural beams;wood or steel. Choosing LSB gives you an advantagefor a number of load bearing applications includingbasement beams, garage beams, ridge beams, long span headers, floor and deck supports, andmezzanine flooring.

7 Drill a 9/16 diameter hole through the wood plate and the LSB flange at each bolt location. Bolt wood plate to LSB flange with 1/2 bolts. A washer is required under both the head and the nut of the screws (SDS) can be used to fix wood plates to LSB Clamp wood plate to LSB. Connect the wood plate to the LSB using screws. Winged SDS, counter-sunk SDS and hex head SDS can be used. Minimum of three full threads should protrude through the steel. The tip of the screw should not touch the second flange. Drill speed of 2500 rpm is typically required for drilling SDS screw types. Nailer plate connections should be roughly every two feet on selection is important. The screw drillpoint requires a drill and tap capacity that mustbe greater than the material thickness (t). Thelength of the drill point and three threads must beless than the flange void height (df-2xt). Refer tothe table on page 4 for values of df and t for eachLSB size.

8 The length of the screw must be longenough that the drill point and three threadsprotrude through the first skin of the LSB flange,however not so long that the drill point hits thesecond skin of the LSB pre-drilling wood plate, ensure the holethrough the wood is clear of burrs and larger thanthe diameter of the , consistent pressure and speed is of screws vary widely. Test screws on an off-cut of LSB prior to use to ensure they are most efficient way to work with the LSB is to do as much preparation as possible while it is still onthe ground before lifting it into place.
