General Lining Information

Sizes available:
Ultra High manufactures press finished 4000 x 1000 lining sheets in thickness ranging from 10mm upwards. For ease of handling sheets are usually cut in 2000mm x 1000mm sizes. ULTRA HIGH manufactures slit finished approximately 1950mm x 950mm lining sheets in thickness from 3mm to 10mm.

Optimum size:
TIVAR lining sheets because of their weight, have a significant advantage over many other lining materials as they can be installed in large sizes such as 2000mm x 1000mm, thereby minimising flow obstruction joints.
