Merronbrook use modern technology combined with traditional values
to help make your project a success. Design Trussed rafters are designed in accordance with the current Code of Practice, which is BS 5268: Part 3, and the relevant Building Regulations and manufactured in accordance with BSEN 1059. Spans Standard rafters can be designed up to 11 metres in 35mm timber, and 15 metres in 47mm timber. Non-standard rafters with spans in excess of these can be designed but are often supplied as multiple rafters fixed together. Pitches It is more economical to standardise the range of pitches between 15 and 40 degrees, however, trusses may be supplied outside this range. Care should be taken when specifying because deflection problems may arise with such things as very shallow pitches. Eaves Overhangs Any overhang can be supplied to suit the customer's requirements. NB - very large overhangs may cause the rafters to be uneconomical. Spacing Trussed rafters are usually spaced at 600mm, but can also be positioned at 450mm or 400mm to support heavier loads. Timber We use timber which is kiln dried and stress graded, and which complies with current European and British Standards. Preservation Trussed rafters may be treated with one of the new waterborne solutions, or with non-corrosive spirit-based organic solvents. Copper Chrome Arsenate and similar treatments are not recommended. |
