From Custom Storage Tanks
STAFCO is leading the industry with the most reliable fertilizer storage tanks on the market. Our fertilizer tanks are primarily vertical in design but horizontal tanks are offered as well, depending on the application. We build corrosion resistance into every fertilizer tank manufactured. These tanks will always have a 5/16” thick bottom head and 1/4' shell from the bottom ring to the top which exceeds UL listed tank construction requirements. You won’t find that as a standard anywhere else. Every seam on our fertilizer tanks is welded solid inside and out. So when you are looking at purchasing a fertilizer tank consider the following key elements:
How thick is the material used on the bottom head? Our bottom head is always 5/16' thick A-36 carbon steel material
Is it made from one piece of material or multiple pieces? On tanks up to 143' diameter our heads will be made from one piece of material with a 3' flanged rolled up on the outer edge.
Is the exterior of the bottom coated? Absolutely! Our tanks are always coated with a black asphaltum to act as a moisture barrier.
How thick is the material used on the shell? STAFCO tanks will always have a 1/4' shell from the bottom ring to the top. This is a standard developed at STAFCO
Is it the same thickness from the bottom to the top? YES!
How is it welded? Solid inside and out? Our tanks are butt fit construction and welded solid inside and out.
What kind of leak testing is done at the factory before the tank is shipped? We test our tanks three separate times during production to ensure that our customer will feel comfortable that the tank they receive won't leak.
Does the tank come standard with a manway? YES!
If so what size? Our tanks come standard with a 24' heavy duty below liquid manway.
How many fittings come standard on the tank? Our standard tank comes with a 24' manway, two 1' fittings for your sight gauge tubing, one 3' fitting for your fill/draw and a 3' T-Vent installed in the roof.
How will it be delivered? All tanks up to 143' dia and 36' long can be delivered on a tip up trailer. This gives you the comfort knowing you won't have to pay added crane costs associated with unloading the tank.
Fertilizer tanks from STAFCO are engineered with benefit of our six decades of experience in the industry and receive the best in customer service to make your buying experience easy.
