Description The Pergola Top Beam is produced with ‘S’ shape ends and can be notched to sit on top of pergola main beams. As with the main beams, we would suggest the use of 47 x 100mm for smaller pergola spans, 47 x 125mm for span up to 3.6m and 47 x 150mm for spans up to 4.8m. All pergola products from TATE Fencing are fully treated and tanalised softwood. For all pergolas, the size of timber used is important so the structure not is safe but also creates the right balance of timber to compliment its surroundings.
