The data below is the result of laboratory tests and is intended to serve only as a guide. No performance warranty is intended or implied. The degree of chemical attack on any material is governed by the conditions under which it is exposed. Exposure time, temperature, and size of the area of exposure usually varies considerably in application, therefore, this table is given and accepted at the user's risk. Confirmation of the validity and suitability in specific cases should be obtained.

The importance of chemical resistance cannot be overstated, and choosing the right tank to hold your wastewater or treated potable water is important because over time chemicals wear away at the coatings applied to bolted steel or welded steel tanks. Once that coating is worn away the steel is then susceptible to the caustic nature of those chemicals weakening the tank and putting its structural integrity at risk.

Steel Core is different from all the other bolted and welded steel manufacturers. We don’t just paint on coatings; we use liners in our Corrugated Bolted Steel Tanks.

To the left you will see a sampling of the kinds of substances tested against the chemical resistance of XR-5, one of the premier liners we offer. XR-5 scores an “A” (fluid had little effect) against substances such as:

Crude Oil – Diesel Fuel – Ethyl Alcohol – 50% Sulfuric Acid Solution – 50% Hydrochloric Acid Solution - Sea Water, and more.

We provide XR-3 for potable water at a comparable cost to 45mil. Polypropylene. XR-3 has greater resistance to chlorine and other chemicals added to drinking water to ensure public health by killing disease causing water borne virus and bacteria.

We offer a wide variety of specialty liners along with our 6 standard liners. You can visit our liner page to read more about each individual liner type.
