Glass Fused to Steel Bolted Storage Tanks


First of it’s kind – EVERSTORE® Glass Fused-to-Steel Leachate Tank


Glass Lined or Glass Fused-To-Steel Bolted Tanks panels are fused inside and out with a glass enamel that binds to the metal providing many advantages over standard epoxy coated or welded painted storage tanks.

CarsonThe glass coating forms a hard, chemically inert layer that permanently protects the steel surface from rust, corrosion, undercutting, abrasion and stains.  In addition UIG’s proprietary EVERSTORE TM  coating is specifically engineered around your application from pH zero to pH 14 providing even more corrosion resistance.

The Glass Fused-to-Steel Bolted Tank construction exceptional for the storage of potable water, waste water, petroleum, chemicals and dry bulk and in such applications as reservoirs (open top or with aluminum dome or flat panel roof), power generation stations, standpipes, frac processing, fish ponds, sludge tanks, trickling filters, high temp fermentation plants, anywhere where steel corrosion might be an issue.



Glass Fused to Steel Bolted tanks are a very popular choice for water storage tanks but how do you make sure you are specifying the right manufacturer for your project?

UIG Glass Lined Storage Tanks not only conforms to the AWWA D103 standards but FAR EXCEEDS the standard by providing a stronger, safer product.

Glass Fused-To-Steel Storage Tanks are quick to manufacture and can be erected easily in the field with our experienced crew or by utilizing a supervisor and local labor.

Proper steel and coating thickness is key to elasticity and longevity.  UIG uses proprietary Titanium (Ti) rich Hot Rolled Carbon Steel (TRS TM) which is specifically manufactured for the enameling process.  This allows for exceptional physical performance and eliminates any fish scale defect.  Furthermore the superfine glass structure of the enameled layer provides the steel plates with excellent flexibility and durability.

We make our own glass frits for the enameling process so we can match the color YOU WANT for your tank.



Many other manufacturers choose a poorer quality A36 Carbon Steel as the base for their panels.  It is less expensive than UIG’s Titanium Rich Steel and contains levels of carbon that will make it difficult for good glass adhesion.  Many manufacturers apply a toxic nickel oxide to cover up the carbon defect in inferior steel in order to apply their two-coat/two-fire enameling process which will leach through any pinholes.  As a result they end up with thicker coating that has the tendency to fish scale, sag, has low adherence and cracks easily.

All tank openings, nozzles and bolt holes are factory located and laser cut prior to the vitreous porcelain enamel glass application.  UIG makes sure all edges are fully encapsulated unlike other manufacturers which have their installers field locate their nozzles and opening leading to cracked glass coating and early corrosion.

Factory cut nozzles and openings in the tank panels means all edges are coated.


Most manufacturers use the same fin-necked bolts to assemble their glass lined tanks as they use for their epoxy coated tanks.  Epoxy tanks can be touched up in the field which allows for the use of these types of bolts but using these same bolts on glass lined tanks allow the fins to bite into the enameling leading to cracking and scratches which can cause rusting inside the tank.

UIG’s proprietary finless bolts are safe to use with glass fused-to-steel bolted tanks and do not crack the enamel during the installation process.
