Biligom® Structural / Construction timber is manufactured from young Eucalyptus Grandis and Eucalyptus Camaldulensis trees. All timber produced at Biligom® plants are mechanically stress graded to equivalent S9 values and treated with Tanalith-“E” to H2 SANS specifications for the roofing industry. Biligom® has its own grade known as “Biligom® structural grade”. Biligom structural timber is SATAS and ITC approved and is therefore a legal alternative timber for roofing and engineering purposes. Rational roofing designs are possible because of testing done by the University of Stellenbosch and Mitek.
