QUALITY OF PRODUCT
| Alpine trussed rafters are manufactured from softwoods strength graded in accordance with either BS4978, BSEN518, BSEN519 or as recommended in BS5268: Part 2 and punched metalplate timber fasteners which have been fully tested and certified by UK Accreditation Authorities. |

All trussed rafter designs are prepared in full accord with relevant British Standard Codes of Practice, notably BS5268 Parts 2 and 3 in the UK and NSAI Standards IS193 in Eire. Designs also fully meet the requirements of the current statutory Building Regulations.
Timber for trussed rafters may be protected against biological degradation and insect attack by the use of preservative pre-treatment. Advice should be sought from the truss suppliers regarding suitable forms of treatment.

Dickey and Co. enabling them to provide highly developed designs for almost any truss configuration and which, if required, will also prepare comprehensive roof layout drawings and details according to the exact requirements of individual projects.
