DIRECTANK has been appointed the exclusive US reseller for OptiDome by CST in the oil and gas market, effective April 2026 — a partnership that concentrates all US oil and gas sales, quotation requests, and customer service for CST’s flagship geodesic aluminium dome cover system through a single Conroe, Texas-based distributor. The directank optidome cst arrangement was announced on 16 April 2026 and marks a deliberate channel strategy by CST Industries to pair its dome technology with a specialist oil and gas distributor rather than managing direct sales across a fragmented customer base.
OptiDome by CST: What the Product Covers
The OptiDome is CST Industries’ next-generation aluminium geodesic dome cover — a flush batten design that combines the engineering heritage of Temcor and Conservatek, two legacy dome manufacturers absorbed into CST through earlier acquisitions. The product is manufactured exclusively in the United States and is designed to comply with API 650G, AWWA D108, Eurocode, the Aluminum Association’s 2010 Aluminum Design Manual, and IBC 2012 — the full suite of standards governing tank cover design for oil and gas terminal applications.
At the core of the OptiDome system is its flush batten seal technology. The enclosed gasket design eliminates ponding and increases water shedding even on low-profile installations, while protecting against UV exposure and sealant degradation. Battens flush with dome panels mean no external sealant is required at the nodes — a claimed industry first from CST that reduces maintenance requirements over the dome’s service life. The double web I-beam structure provides structural performance under heavy snow loads and high wind speeds, with freespan capability of up to 900 feet covering the full range of storage tank diameters used in oil and gas terminal infrastructure.
Geodesic aluminium dome covers serve a specific function on aboveground storage tanks — they prevent rainwater ingress and product contamination, reduce vapour losses from open-top tanks, provide structural protection against wind and environmental loading, and in many configurations support vapour recovery system integration. For oil and gas terminals handling volatile liquid products, dome covers are a standard specification on larger fixed-roof tanks and a retrofit option for open-top floating roof tanks requiring additional weather protection.

DIRECTANK’s Role as Exclusive US Reseller
Under the directank optidome cst agreement, DIRECTANK becomes the primary point of contact for all OptiDome inquiries and requests for quotation in the US oil and gas market. The Conroe, Texas base positions the distributor at the heart of the US Gulf Coast tank terminal and petrochemical market — the most concentrated oil and gas storage infrastructure cluster in North America.
Brandon Austin, President of DIRECTANK, described the partnership as filling a meaningful gap in the company’s existing product portfolio. DIRECTANK already serves the US oil and gas market with a range of storage tank equipment and services; OptiDome adds a dome cover capability the company had not previously offered, allowing it to present customers with a more complete product set for new tank construction and tank cover replacement projects.
Courtney Hyde, Director of Sales at CST Industries, described the selection of DIRECTANK as based on the distributor’s strong customer relationships and exceptional service reputation in the US oil and gas market. The channel partnership model — appointing a single exclusive reseller for a defined market segment — is a distribution strategy that concentrates market development effort and accountability rather than spreading CST Covers’ direct sales resource across a fragmented inquiry base.
Market Context: Geodesic Dome Covers in Oil and Gas Storage
The US oil and gas storage sector represents one of the largest addressable markets for aluminium geodesic dome covers globally. The American Petroleum Institute estimates there are more than 553,000 aboveground storage tanks in the United States — a substantial proportion of which are candidates for dome cover retrofits or replacements as part of regular inspection and maintenance cycles under API 653.
Dome cover demand in the oil and gas sector is driven by three overlapping forces in 2026: emissions compliance requirements under EPA regulations governing volatile organic compound releases from storage tanks; product quality protection requirements for refined products and chemical feedstocks sensitive to water contamination; and HSE performance improvement programmes at terminal operators seeking to reduce tank-related incident risk. All three factors support steady replacement and new-build demand for dome cover systems across the US Gulf Coast and midcontinent terminal markets.
The directank optidome cst partnership enters a market that includes competing dome manufacturers, but CST’s position as the world’s largest dome manufacturer — with more than 40,000 covers installed across 90 countries — gives the OptiDome product line a reference base and supply chain depth that smaller competitors cannot match.

OptiDome is CST Industries’ flagship aluminium geodesic dome cover system — a flush batten design complying with API 650G, AWWA D108, Eurocode, and IBC 2012. It features superior batten seal technology that eliminates ponding and UV-protected enclosed gaskets requiring no external node sealant. OptiDome can cover freespans of up to 900 feet and is manufactured exclusively in the United States.
Why do oil and gas storage tanks need geodesic dome covers?
Aluminium geodesic dome covers prevent rainwater ingress and product contamination, reduce vapour losses from open-top tanks, provide structural protection against wind and environmental loading, and support vapour recovery system integration. For terminals handling volatile liquid products, dome covers help operators meet EPA volatile organic compound regulations and API 653 inspection requirements.
Where is DIRECTANK based and what markets does it serve?
DIRECTANK is based in Conroe, Texas — at the heart of the US Gulf Coast oil and gas storage and petrochemical market. The company serves the US oil and gas sector with storage tank equipment and services, with the OptiDome reseller agreement adding a geodesic dome cover capability to its existing product portfolio from April 2026.
Who manufactures the OptiDome and how widely is it used?
