I am going to be building a new stand for at least 8 600 x 300 x 300mm Tanks. 4 per shelf as per diagram below, with the top shelf as extra room for smaller tanks if needed at a later date.
I am looking to build it with 4x2 (100x50) hopefully with uprights at each end only, but don't know if it will be strong enough.
There will be approximately 250KG on each shelf.
I plan to have the front and back 4x2 of each shelf inset into the uprights sitting 4" high 2" deep with 12-20mm plywood/MDF board flat across the top for extra support . The total length of the stand would be 2540mm.
Would this hold the weight??
