The X-type structure provides these sheets with additional strength, rigidity, and excellent thermal insulation. It can support larger purlin spacing, thereby reducing the amount of profile material used. The enhanced diagonal support plays a positive role in stabilizing the hollow sheets. The 3-wall X-type structure hollow sheets are available in two width specifications: sheets with a width of 2100mm are offered in three thicknesses—12mm, 14mm, and 16mm; sheets with a width of 1220mm are offered in four thicknesses—12mm, 14mm, 16mm, and 18mm.
