we would consider being a mesh distributor.
You can visit http://www.alibaba.com/ or www.made-in-China.com to find the good suppliers in China.
Actually for this product the main problem is the price,most of them made by steel,and the technical difference is very few between the different brands,wish you can find the excellent goods.
Most rack distributors also sell wire deck. You can try the Material Handling Industry of America (mhia.org) they would have the information you are looking for.
There is a company called, Manta Mesh here in Australia (State - new south wales). Most distributors sell directly to the pallet racking companies.
If you require multiple pallet racking companies details here in Australia, please reply to me. Good luck.
