CNC Machined

Engineered solid sawn lumber by structurally finger joining high quality pieces of lumber and then planing the engineered joist to precise dimensions which virtually eliminates shrinkage.

ULTRAJoist - A strong lightweight floor system Engineered for Mid-Rise (6 storey) Construction:

How to Create a 40ft long 2x10 Structurally Finger Joined ULTRAJoist:.

ULTRAjoist lumber is kiln dried to 14% moisture content.  Then treatment for flame retardant and moisture repellant is applied using a double vacuum, low pressure treatment process that treats all six (6) faces of each piece of lumber at once.
