Internal vs. External Bracing Systems

To maintain structural rigidity, our rectangular panel tanks are engineered with two primary bracing options depending on your site requirements:   

Internal Tie-Rod System

Utilizes stainless steel or galvanised rods inside the tank to hold the walls together. This is the most space-efficient option, allowing the tank to be placed flush against building walls.  

External Structural Bracing

Uses heavy-duty steel beams on the outside of the tank. This leaves the interior completely clear for easier cleaning and maintenance, though it requires additional clearance around the tank’s perimeter. 

Engineering Support, Delivery & Installation

At Raven Tanks, we support your project from design to installation. Our team assists with tank layout, capacity planning, and configuration to suit site conditions and compliance requirements.

Once the final design is approved, tanks are typically delivered within 6 weeks, with installation completed in 1–4 weeksdepending on size and location. Timelines may vary based on project scope.

For specific delivery or installation requirements, our team is ready to assist.

Client Questions – Our Answers

We know our clients often have important questions before starting a project. Here are clear answers to help you make informed decisions with confidence.   

Yes, their modular nature allows us to transport components through standard access points and assemble the tank entirely on-site.

Our modular systems are highly scalable, ranging from small 5kL units to large-scale industrial reservoirs exceeding 1,000kL.

We use internal stay-rods or external heavy-duty steel bracing (depending on your preference) to ensure the walls remain perfectly rigid under full hydraulic load.

Our designs include dedicated internal or external ladders and roof hatches. Because of the modular square panel tank design, individual sections can be inspected or replaced without needing to decommission the entire system.
