TeleBeam has been developed primarily for the conversion of fink pattern roof trusses at nominal 600mm centres, with a maximum clear space from 6.2m to 8.4m (depending upon which system is used, i.e., TB6.2 has a maximum clear span of 6.2m) between external walls with normal interlocking concrete tile or slate loading. Please check that your installation complies with these limits. If in doubt please consult TeleBeam for further clarification.
