Lignacite manufacture trough lintels and beam lintels
Trough lintels (available in full trough lintel length or half trough lintel length), are cut from the same trough lintel blocks produced on the trough lintel block making machine
This enables trough lintels to have a close colour match
The open core of trough lintels is filled with trough lintel reinforced concrete
Trough lintels have increased performances compared to other lintels and longer trough lintel spans are possible
Trough lintels are available in standard trough lintel or metric modular trough lintel lengths
