Outer Limits 4x4 Board

Does anyone know some places in Brisbane that stock checker plate in 1300 x 1000 or bit bigger, preferably in the black powder coat. Around Northside Bris would be good.
Thanks

My only sugestion is hit up the steel joints.

onesteel they have a wearhouse down at yatala

Steel barn, they are now at crestmeade industral park.

no idea on sizes, I know onesteel can cut stuff to size.

i work at a sheet metal company at eagle farm. we get checker plate sheets in 2400x1200 could get a price if you want for some black powder coated stuff, dont think it will be real cheap, its usually about 80 to 100 bucks a sheet 2mm thick for non powder coated stuff
