Corrugated Bolted Steel Tanks

WALL PANELS:

Corrugated Bolted Steel tanks are made of Carbon Steel panels, Zinc Galvanized at different thicknesses.

G115 and G140 galvanization are most commonly used. Sheets range in gauges depending on the engineering calculation for a specific tank. This is based on the usable gallon requirement, project coordinates, and tank use/application. Structural engineering conforms to all calculations required by ASCE 7-10, which is the structural code written for all structures that hold water, regardless of the materials the water storage tank or structure is made of.

Each ring of Corrugated Bolted Steel tanks will be called out by engineering with the heavier gauge steel lower on the tank structure. ASCE 7-10 calls out the required wind, seismic, snow load & risk categories.
FLOORS:

Corrugated Bolted Steel Tanks are commonly installed on a concrete foundation. No steel floor is needed, as the concrete foundation becomes the floor of the tank. The tank walls are seismically anchored to the foundation as needed. Supports the Flexible Membrane NSF61 certified and Geotextile Pre-liner system.

Steel floors are only used in the case that the tank is engineered to be self-anchored and installed on a compacted granular/road base ring foundation.

ANCHORS:

Anchoring of a tank is required when installing on a concrete foundation, in any location for any use, unless the tank has a steel floor and is engineered self-anchored. Anchors meet ASCE7-10 and all AWWA requirements with the use of tall anchor saddles and A36 F1554 zinc or galvanized all thread anchor rods. Standard non-seismic anchors, Heavy Duty Seismic Anchors, Stiffener Plates and Fully Stiffened options are all available.

ROOF STRUCTURES:

Corrugated Bolted Steel Tanks have multiple roof style options to suit many requirements, both structural and aesthetic. Roof types include: 30 degree V Rib, 10 Degree V Rib, Structured 30 degree V Rib, Structured 10 Degree J Rib, Flat Corrugated and 30 Degree Flat Panel.
