Upon request Au-mex panels of 15mm, 18mm and 21mm of all available grades may be delivered with T&G (tongue and grooved) machined profiles on the long edges.
T&G panels are especially recommended for floor and roof decking applications to obtain an increased point load resistance on panel joints. They may also be a good option for wall paneling, offering very well matched joints.
T&G profiling is a sizing operation so panels have a net face width of 1.205mm +0 / -3mm.
A specially designed gap is left on the back of the T&G joints so that panels can expand slightly when in contact with water, avoiding undesired buckling problems.
