Description A Pergola Main Beam is produced from 47 x 125mm or 47 x 150mm timber depending on the span. 47 x 100 timber also available for smaller pergola spans. These are generally ‘S’ shaped at both ends in our workshops (included in price) or can be left square for you to shape during assembly. For example, we would suggest the use of 47 x 125mm for up to a 3.6m span and 47 x 150 for up to a 4.8m span. All timber is fully treated and tanalised softwood. As with all pergola components, the main beams are made specifically to your order and non-standard lengths of timber can be cut to order.
