We are a privately held manufacturer and erector of internal floating roofs - and perimeter seal systems for above-ground storage tanks and covers for API separator basins

About Us

Worldwide, ALLENTECH’s reputation in the petrochemical industry is unmatched for delivering superior products with unsurpassed service. Providing a focused product line enables us to oversee every design, manufacturing and installation detail throughout the entire process.

We operate out of one primary design and manufacturing facility located in Pennsylvania’s Lehigh Valley region, just 90 minutes from the New York and Philadelphia metropolitan areas. We are situated along several major interstate highways allowing easy access to all domestic shipping routes and major seaports.

About the Process

Ultra-modern computer and manufacturing processes, strict control measures, and a highly skilled and trained workforce allow us to meet our quality and delivery commitments to our customers.

Because personal safety is a priority and a promise we make to our employees and our customers, ALLENTECH’s Safety Program is among the most comprehensive in the industry.

ALLENTECH fabrication and field personnel are veteran employees and experts in their work.

Using carefully developed and time-proven installation techniques, sound work procedures and stringent company safety policies, ALLENTECH crews install our internal floating roofs and perimeter seal system products throughout the United States.

We also sell ALLENTECH products to domestic contractors who choose ALLENTECH because of our reputation, product reliability, design excellence and ease of installation. These contractors install with their own crews.

Materials sold outside the United States are installed by representatives trained to the high standards of ALLENTECH field crews and in some cases, non-US installation are overseen by a U.S. based installation consultant who travels to the site.

At ALLENTECH, our objective is to deliver quality products to meet or surpass your expectations so that your tanks can be returned to service as promptly as possible and provide you with years of trouble-free service.
