A license for the Anolok process was gained in 1971 and since then LHT has produced more Anolok bronze anodising than any anodiser in Europe.
In 1983 two further licenses were obtained, one from Interoxyd for the Sandalor range of bright colours, and one from Alcan International for Anolok II, a range of grey colours produced by optical interference.
To combat the growth of powdercoating, the problems of colour matching anodising were addressed in 1987 by introducing "Unicol" Japanese colour matching technology which significantly improves colour uniformity on individual pieces and batch to batch.
