Modern Container Frames
RBT
Our bolted frames serve as a modern alternative to traditional welded structures in the modular construction industry. We provide a system that is faster, more cost-effective, and easier to assemble.
This makes container construction accessible to virtually anyone, regardless of prior experience or access to specialized equipment.
Save Time and Money: Bolted vs. Welded Frames
RBT
Our bolted frame technology delivers tangible benefits that directly impact your bottom line.
- Lower Transport Costs: A single truck can transport up to 10 times more flat-packed frames compared to pre-welded structures. This radically reduces logistics costs, maximizing your investment ROI.
- Assembly Anywhere: Assemble frames directly on-site. This eliminates the limitations and high costs associated with oversized load transport to hard-to-reach locations.
- Precise Fit: Every frame is custom-manufactured to your specific order requirements.
- Immediate Corrosion Protection: Our profiles are made from galvanized or ZM (Zinc-Magnesium) coated steel, providing immediate, durable protection without the need for additional painting or post-assembly treatment.
- Regulatory Compliance: You need just 3 people and basic tools to assemble the frame. Our systems are engineered for an easy and intuitive installation process.
Quick and Simple Assembly: You only need 3 people and basic tools to assemble the frame. Our frames are designed to ensure the assembly process is easy and intuitive.
Cold-Formed Steel: Lighter & More Efficient than Hot-Rolled Sections
RBT
Cold-formed steel (CFS) technology is the cornerstone of our frames’ performance. Unlike traditional hot-rolled sections, which come in fixed standard sizes, our profiles are precision-engineered to your exact specifications. Key advantages include:
- Superior Corrosion Resistance: We utilize high-grade structural steel (S320GD, S350GD, S390GD) with advanced Zinc or Zinc-Magnesium (ZM) coatings, ensuring maximum protection against rust.
- High Strength-to-Weight Ratio: Our profiles are significantly lighter than traditional steel, which simplifies assembly while maintaining exceptional structural integrity.
- Cost Efficiency: Optimized design reduces raw material consumption, resulting in a more competitive price without compromising quality.

Everything You Need
RBT
We believe the foundation of any durable structure lies in perfection down to the smallest detail. Our cold-forming technology delivers precision, ensuring every component fits seamlessly to eliminate structural weak points.
- Corner Posts, Top & Bottom Rails: These components form the robust skeleton of every frame.
- ISO Corner Castings & Assembly Hardware: A complete set of bolts, nuts, and washers tailored to each specific frame, supplied by industry leader Rawlplug.
- Floor & Roof Cross Members: These profiles provide structural stability and simplify the installation of wall and roof cladding.
Corner Posts
Corner Posts form the structural backbone of the entire frame. They are responsible for transferring vertical loads – both from the roof and external forces such as wind. Their precision manufacturing ensures a seamless fit with the rails, which is critical for rapid assembly.
Bottom Rails
Bottom Rails act as the foundation of the container structure, transferring loads from the floor and internal components. Thanks to precise manufacturing from cold-formed steel profiles, the bottom rail ensures exceptional stability and rigidity for the entire frame. Its high durability prevents deformation, simplifies assembly, ensures safety, and guarantees even load distribution. Innovative design allows for quick, easy installation using only basic tools, significantly reducing labor costs and construction time.
Top Rails
Top Rails play a vital role in stabilizing the entire structure, connecting the corner posts and distributing roof loads. Precision manufacturing from cold-formed profiles ensures not only high stability but also resistance to external forces, such as wind or heavy snow loads. They guarantee that the structure maintains its original geometry and a level roof surface. Their easy assembly and high-quality materials ensure the reliability of the entire frame.
Corner Castings & Assembly Hardware
Reliable corner castings are the key to the structural rigidity and rapid assembly of our frames. We supply complete sets of screws, nuts, washers, and fasteners that are precision-engineered to match the pre-punched holes in the sections. We utilize high-grade hot-dip galvanized steel, guaranteeing superior corrosion resistance. This solution ensures the long-term durability of the entire container frame.
Floor Cross Members
Floor reinforcement cross members are critical components that protect your frame from deflection and ensure even load distribution. Thanks to precise manufacturing, you are guaranteed a stable, rigid floor surface. Our cross members are designed to maximize the load-bearing capacity of the structure, which is essential for heavy cargo or when reliable support is required.
Roof Cross Members
Roof reinforcement cross members are key, though often overlooked, components that significantly increase the stiffness and safety of your container frame. We understand that roof stability and proper support for ceiling cladding are just as important as the strength of the walls and floor.
