Structural Function
Positioned at the top section of the IBC cage, the horizontal frame tubes act as a final locking mechanism that secures the entire structure.
Their main functions include:
Reinforcing the overall rigidity of the steel cage
Securing the inner plastic tank in position
Enabling the IBC to pass UN stacking, drop, and vibration tests
Maintaining structural stability during transport and storage
Precision Manufacturing Process
The production of IBC steel tie bars involves a multi-stage automated process to ensure strength, accuracy, and consistency:
Material Preparation – Starts with galvanized steel coil
Die Cutting – Forms the initial flat profile
Tube Forming & Welding – Shaped into a tubular structure with a welded seam
Bending – Achieves the required structural profile
Stamping & Punching – Creates hook-shaped ends and precise mounting holes
This process ensures each tie bar meets strict dimensional and mechanical requirements.
Assembly and Installation
The horizontal frame tubes are installed during the final stage of IBC assembly, after the inner plastic tote is placed the steel cage.
Key installation details:
Each bar measures 970 mm in length
Two bars are installed across the top middle section
Bars are threaded through two upper rims of the inner tank
Hooked ends securely lock onto the P-shaped top horizontal frame tube
Once installed:
The bars lock through four vertical pipes and the top frame
External reinforcement is provided by four tie-bar brackets (39 mm × 37 mm)
These brackets secure the internal bars from outside the frame
This combined internal and external locking system ensures maximum structural integrity.
Material and Strength
The tie bars are manufactured using 1.0 mm thick steel, providing excellent strength while maintaining manageable weight.
Performance characteristics:
Designed to withstand stacking of up to four empty IBC containers
High resistance to deformation under load
Durable enough for repeated industrial use
Corrosion Protection
Given that IBC containers are often used in outdoor and chemical environments, corrosion resistance is essential.
To ensure long-term durability:
The steel is coated with ≥80 g/m² zinc (galvanization)
This coating provides a proven barrier against rust and corrosion
Maintains structural integrity even in harsh conditions
