3.Acp wooden texture- range Rs. 210-280 per sq ft
4.Shera wood

thanq.could upls send me some models used of that meterial

hi, i am attaching images of fundermax.it's 6mm thick. fundermax is double sided, when one side is faded you can change it to other side. and it's the first material to use wooden material in elevation.

hi, this is hpl, 6mm thick. it's same as fundermax, but its color fades in 2-3 years if you don't go for good brand. it's also double sided.

hi, it's acp sheet(3-4mm thick). wooden texture on aluminium composite panel. it's color doesn't fade for longer time.its single sided if you want double sided you will get it with 6mm thickness but there's no need.
