The installation time for bolted tanks depends on the sizes of the tanks installed, and the complexity of the installation process. Normally, the installation is very quick, often requiring less than a third of the time it typically takes to complete a welded or a concrete tank, but factors such as site complications or specific job requirements can alter the installation time.
Bolted tanks are made from individual sections that are manufactured and finished offsite, greatly reducing the time and labor involved in the field. Once delivered, each section is erected, sealed with gaskets and bolted to adjacent sections. This results in an installation process that is quick and easy, far faster than installation of concrete or welded tanks, and it is not subject to the weather delays that often stall the installation of competing designs.
First, the installation site is prepared by clearing the land of vegetation and debris, then the site is graded to create a level surface. A solid base of sand or crushed stone is applied, followed by either a concrete ring wall or a full concrete slab. The site preparations can be carried out either by the customer or our tank installers.
Once the site is prepared, the individual panels are erected, one layer at a time, starting from the bottom of the structure. Gaskets are fitted between adjoining panel sections, creating a strong seal and preventing damage to adjoining metal surfaces. The appropriate fasteners are subsequently installed and torqued to specification. Fittings such as valves, doors or manhole covers are added as necessary, and finally, the tank's roof is installed.
Because the installation is performed in large sections, the tank can be erected quite quickly, and because each section is sealed or powder-coated at the factory, there is no sandblasting, painting or other preparation required in the field.
Bolted tanks are made from individual sections that have been manufactured and finished in a controlled factory setting. This allows each section to be formed according to strict structural specifications, with quality bends, welds and surface preparations that are monitored with comprehensive quality control measures. Once the sections are complete, they are powder-coated in a tightly-controlled environment, which results in a durable finish that virtually eliminates corrosion and maintenance issues; unlike field-welded tanks, which must be finished at the installation site, often resulting in an imperfect and inconsistent finished coating that is susceptible to corrosion and other damage.
Bolted tanks are created with superior materials that meet AWWA, NFPA, API, and FM Global standards, resulting in a long-lasting, durable product. They offer lifespans that are similar to, or longer than, concrete or welded tanks. Unlike competing products, they can easily be repaired by unbolting the damaged section, replacing it and installing new gaskets and fasteners.
Bolted tanks are used anywhere that there is a need for bulk storage of materials, including water, waste-water, dry good or food products. They are often used in industrial, commercial, residential municipal and rural applications, ranging in size from a few thousand gallons to over a million.
They are commonly found as storage tanks for potable water in municipal water systems, for wastewater treatment in industrial or municipal systems, or for storage of dry goods, like sand, for concrete plants or oil drilling operations. Bolted tanks can also be used to store fire suppressants for emergency services, and food-grade tanks can be used for storing grains or other dry ingredients, or for liquids, such as milk or fruit juice.
Is it possible to repair leaks on bolted tanks?
Leaks can occur in every type of tank; bolted tanks are no exception. The good news? It’s possible to repair leaks on bolted tanks, and typically takes a lot less time and is much more cost effective compared to other types of tanks.
In many cases, hydrotesting will discover a leak before it occurs as the tank’s joints become ‘stretched’. Simply tightening the bolts and adding additional tank sealant should be sufficient to permanently re-seal the tank. Once a leak-free hydrotest has been achieved, it’s rare for another leak to develop without some type of external influence.
If there is an external influence, like a puncture by a sharp metallic object, then bolted tanks offer an easy solution without expensive welding and coating repair. Each component of the tank can be quickly and easily removed and replaced. For tiny holes, a professional may even repair the hole with the use of another bolt, nut, and industrial-grade mastic sealant.

What’s different about modern bolted tanks?
Industries have been using bolted tanks for storage purposes for decades, with some older units still in use today. There have been many advances in the design and construction of these tanks since those early days. Here’s what you should know:
Why Steel Bolted Tanks are the Best Choice for Fire Protection & Agricultural Water Storage
There are several water tank options for fire protection and agricultural use. In most situations steel bolted tanks are the best choice. Steel bolted tanks are more advantageous when it comes to considering manufacturing quality, cost, product durability, and the length of time it takes to install.
And that’s just the beginning. Here’s a more thorough look at why you should consider an above-ground steel bolted tank over a concrete or welded tank of the same capacity:
How do bolted tanks differ from traditional steel tanks?
A variety of industries require high-capacity storage tanks for necessary items like potable water, manufacturing chemicals, drilling fluids, food products, and more. Traditionally, these storage tanks were constructed of field-welded tanks, but in recent years bolted tanks have steadily become the number one storage tank choice thanks to its greater construction advantages.
Field-Welded vs. Field-Bolted
Field-welded steel tanks are delivered to the construction site in separate parts. Once all of the parts have arrived, trained and licensed welders must be hired to weld the various parts together. Once finished, every weld must be thoroughly and professionally inspected to ensure that there are no weak welds or places where leaks might otherwise develop. This necessary step to field-welded tanks can cost a lot of money and time that might otherwise be better spent elsewhere. Should any weaknesses develop over time, those same skilled welders must be re-hired to appropriately mend the units.
In contrast, bolted tanks are easier to install and cheaper to maintain. Bolted tanks are manufactured at an offsite facility and shipped together in ready-to-assemble sections. These sections can be assembled by anyone with a basic understanding of a socket wrench and blueprint. As long as the foundation is sound, these bolted tanks can be assembled in just about any type of weather. Should a problem with a leak or marring occur, the damaged piece can be easily unbolted and its replacement bolted into its place.
How Do Bolted Tanks Compare to Other Storage Tanks in Costs?
Bolted tanks are arguably the most cost-effective storage tank available. This is the ideal economical alternative for those looking for long-lasting storage solutions on a budget. Not convinced? Here are just some of the ways bolted tanks can save you on the costs associated with installing storage units:
Can Bolted Tanks Be Easily Expanded For Future Uses?
One of the biggest issues customers have with traditional welded or concrete tanks is that it is extremely expensive and time-consuming to retrofit fit them once they’re installed — making it more cost-effective to add addition tank.
In stark contrast, bolted tanks can be easily expanded to meet any needs for capacity increases. The ease of removing sections and adding additional sections either vertically or horizontally with bolted tanks enables operators to keep costs low, minimize business downtime, and take full advantage of any space constraints you might have at your location.
THE MOST DURABLE, RELIABLE, AND ECONOMICAL CHOICE IN ABOVE GROUND STORAGE TANKS
“We were replacing an old storage tank and required that the new tank use the same footprint, because space is limited. It was tough to find the right product, but Gulf Coast Tank & Construction designed a tank to fit perfectly. Thanks.”
“We pickle several types of foods, including eggs and cucumbers, and needed a tank that would withstand the acidic effects of vinegar. Gulf Coast Tank provided us with a food-grade tank that has exceeded all specifications, and it looks great.”
