ok got my parts from http://www.righton.co.ukwww.righton.co.uk .these people were very nice as they gave me alot of stuff. the stuff includes 3 1m x 700mm x 6mm poly carb , 3 1m x 700mm x 3mm Aluminium , 1m x 700mm x 5 mm of Alu checker plate and a mystery shee!! What is that mystery sheet you may ask well i did a lot of research before and i have never heard of this be for . its called DIBOND by Alcan Composites. it seems to be very light yet very strong for about 4mm thick.Its looks like its made of a mm of alu 2-3mm of ploycarb and then another mm of alu. does anyone know what this stuff is ??
