How does the Fast62 aluminum frame system achieve curved exhibition booths?— Modular structure and dedicated connectors
Many planning companies, when first encountering the aluminum frame system, assume it can only build straight-line booths — after all, the profiles and corner brackets are straight. But the Fast62 system has incorporated curved booths into its modular design from the start, without the need for additional custom bent tubes or welding. Instead, it uses a set of dedicated connectors to allow standard 62mm profiles to switch freely between straight lines and curves.
62mm high-strength aluminum alloy profiles and welded corner brackets: the stable foundation for straight-line structures
First, understand the straight-line part. The profile cross-section of Fast62 is 65.5mm × 45.5mm, and the wall thickness and internal reinforcement ribs ensure better bending resistance at a height of 4.5m. And all straight-line nodes useWelded Integrated Corner Fittings—The corner fitting itself is integrally welded, not an assembled part, so the rigidity of each right-angle connection point is fixed.
This means: as long as the straight frame is set up, it forms a stable rigid skeleton that will not loosen due to subsequent addition of curved components.
Full-Spec Curved Connectors: Modular Expansion from Straight to Curved
The core of realizing a curved exhibition booth lies incurved connectors。 These connectors are pre-formed aluminum parts with fixed curvatures (common specifications include 90°, 120°, 180°, etc.), and the interfaces at both ends are fully compatible with 62mm profiles. When building, you only need to:
- Plan the positions of straight and curved sections according to the booth dimensions;
- At locations requiring turns, replace straight corner connectors with curved connectors;
- Insert standard profiles into the interfaces of the curved connectors and tighten with hex socket bolts.
Key Trade-off: Curved connectors have a fixed curvature, not an adjustable one. This means you need to determine the turning radius and angle of the booth in advance, then select connectors of corresponding specifications. If the booth requires multiple curved sections with different curvatures, you will need to prepare multiple sets of connectors with different specifications.
Stability Assurance: The curved connector itself is made of aluminum alloy casting or CNC machined parts, with wall thickness consistent with the corner fittings. When the profile is inserted and locked, the connector and the profile form a rigid whole. With the support of the straight section frame, the entire curved structure is no weaker than a straight structure.
In actual tests, a 4.5m high curved booth requires no additional reinforcement under standard wind loads (indoor exhibition hall environment).
Who is suitable and who is not
- Suitable: Planning companies that need curved entrances, wavy backdrop walls, circular or semi-circular booths;Builders who want to achieve curved effects using standard parts and avoid the custom bending pipe process.
- Not suitable for: Design schemes that require free curves (such as S-shaped double bends or irregular arcs) — because the arc connectors have fixed curvatures and cannot be bent or adjusted on site.
Next Confirmation Steps
If you have a floor plan or rendering of the booth, we recommend sending it directly to our technical team. They will help determine: whether the existing arc connector specifications can cover your curvature requirements? Whether multiple connectors with different curvatures need to be combined? And, within a height of 4.5m, which curvature specifications can be used directly without reinforcement.
How High Can the Arc Frame Be Built?Fast62's 4.5-Meter Building Capability and Structural Stability
The maximum construction height of the Fast62 curved frame is4.5 meters, consistent with the straight frame. This means that in curved booth designs, the curved section can also achieve a clear height of 4.5 meters, without sacrificing height for the shape.
Maximum 4.5 meters: the same height limit applicable to the curved frame
The Fast62 system uses 62mm aluminum alloy profiles, and the curved frame shares the same 4.5-meter height limit as the straight frame. This height limit is based on the system's structural design and applies to both straight and curved forms. At a height of 4.5 meters, the lateral force distribution of the curved frame differs from that of the straight frame—the curved structure generates lateral components, but through proper design, it can meet usage requirements.
Heavy-duty stable structure: load-bearing and safety considerations of the curved frame
Fast62'sheavy-duty stable structure(Heavy-Duty Stable Structure) provides the foundational support for the curved frame. Key components include:
- Welded corner brackets: used for curved connection nodes to enhance connection strength
- Curved-specific connectors: Ensure reliable fixing between the curved section and the straight section
When using curved frames at a height of 4.5 meters, it is recommended to take the following measures:
- If the curved span exceeds 3 meters, add lateral ties (such as cross braces or diagonal braces) at the top and middle
- Avoid independent load-bearing of the curved frame; it is recommended to use it in combination with straight frames
- Total weight of top-hung items shall not exceed 15 kg/m²
Safety Usage Recommendations: At a height of 4.5 meters, the horizontal torsional resistance of the curved frame is weaker than that of a straight section at the same height. This is a physical characteristic of all curved structures. If heavy items (such as light boxes, LED screens) need to be hung, or if the structure is located in a densely populated area, please provide the technical team with the curved radius, arc length, and weight of the hung items to obtain a specific reinforcement plan.
Which scenarios are suitable for using the Fast62 curved frame?— 5 typical applications from exhibitions to retail spaces
The Fast62 curved frame is not a "universal curve tool," but in the following 5 scenarios, its value is very clear. If you are struggling with "whether my project can use it," first look at these 5 typical matching scenarios.
1. Large-scale industry exhibitions: curved backdrop walls and brand image areas
Suitable for: Exhibitions with booth area ≥ 36㎡, requiring visual impact, and where the brand demands "curved shapes" in booth design (e.g., consumer electronics shows, auto shows, luxury goods exhibitions).
Why it is suitable: Straight aluminum frames can only form square structures, while the Fast62 curved frame (compatible with 62mm aluminum profiles, up to 4.5m) can create continuous curved backdrop walls with a radius ≥1.2m, paired with stretched fabric graphics for seamless curved displays. Compared to custom wood curved walls, it can be repeatedly disassembled and reassembled, with smaller transport volume.
Not suitable: If your booth is only 9 sqm and the budget is extremely tight, the additional accessory costs for curved frames (curved connectors, custom stretched fabric) may not be cost-effective—in this case, a straight frame with partial curved film is more practical.
2. Brand pop-up stores and roadshow events: Quick setup of curved shapes
Suitable for: Shopping mall atrium pop-up stores, new product roadshows, brand experience centers—setup period ≤3 days, non-standard rectangular venues, requiring "eye-catching" curved entrances or product display islands.
Key trade-offs: The Fast62 curved frame's setup speed (2 people can complete a standard curved panel unit in 4 hours) is much faster than welded iron frames or wood shapes, but the curved radius is limited by the profile bending mold—the minimum arc radius is about 1.2m, making it impossible to achieve very tight spirals or S-shapes. If your design requires a sharp bend with a radius of less than 1m, please consult the team about the possibility of a custom mold solution.
3. Retail Commercial Spaces: Long-term Display Curved Partitions or Brand Walls
Suitable for: In clothing stores, beauty shops, and digital experience stores, curved partitions are needed to guide customer flow, or as brand logo background walls.
Why it is suitable: The aluminum frame itself is rust-proof and reusable, and the surface can be replaced with graphics (fabric or PVC graphics), suitable for brands to update visuals every quarter. Compared to fixed decoration, it can be completely disassembled and relocated to a new store.
Not suitable: If the space needs to bear weight (such as hanging heavy objects or installing a TV screen), the load-bearing capacity of the curved frame is lower than that of the straight frame—it is recommended to use the curved section only for graphic display, and reinforce the load-bearing structure with straight frames.
4. Meetings and Events: Curved Stage Backdrops or Registration Areas
Suitable for: Corporate annual meetings, product launches, forums—need curved backdrops that create a sense of enclosure or guide the line of sight, such as a semi-enclosed curved wall behind the main stage.
Key conditions: Maximum construction height is 4.5m. If your stage background needs to exceed 4.5m, you need to splice with straight frames or consider other systems. Additionally, the stability of the curved frame depends on floor fixing (ballast or ground anchors). In outdoor windy venues, additional reinforcement is required.
5. Temporary displays for cultural and office use: curved information walls or art installations
Suitable for: Company showrooms, museum temporary exhibition areas, office cultural walls – need soft curves to break the monotony of linear spaces, with display periods of 1-6 months.
Note: Such scenarios usually have fire rating requirements. The fabric for the Fast62 frame can be selected as flame-retardant material (meeting European exhibition safety standards), but this must be specified at the time of purchase.
Next Confirmation Steps
If you think any of the above scenarios match your project, please confirm the following 3 points with the team:
- Arc radius requirement: What is the minimum radius of the arc in your design drawing?The Fast62 standard mold supports ≥1.2m; smaller radii require customization.
- Load-bearing requirement: Does the curved section need to hang screens, lights, or heavy objects?If so, a straight frame support needs to be added behind the curved section.
- Site height: Does the highest point exceed 4.5m?If so, other frame systems need to be combined.
If all three points above match, the Fast62 curved frame is likely suitable for you. If not, the team can help you evaluate whether design adjustments or alternative solutions are needed.
Fast62 Curved Frame vs. Traditional Straight Frame: 3 Key Questions to Consider When Selecting
The differences between curved and straight frames are reflected in three dimensions: design, cost, and efficiency. The following comparison helps you determine whether the curved solution is worth choosing.
Design Requirements: Is a curved shape necessary?
Curved frames are suitable for scenarios that require curved guidance of movement lines or echo brand visuals, such as main aisle corners, island booths, or brands in automotive, cosmetics, and other industries. If the booth area is less than 18 square meters, has a standard single-opening layout, or the content is mainly dense graphic panels, straight frames are more efficient, and the visual benefits of curves are limited.
Budget and Long-Term Costs: Initial Investment and Reuse Value of Curved Frames
The initial procurement cost of the Fast62 curved frame is higher than that of a straight frame of the same specification, mainly due to the processing technology of curved aluminum profiles. However, curved frames can be disassembled and reassembled like straight frames, and repeated use more than 10 times can amortize the single-use cost, making it more economical in the long run. Setup time is 15%-20% longer than straight frames, but a skilled team can keep it within a reasonable range.
In terms of transportation, the modular design allows disassembly into standard lengths, which does not significantly increase logistics costs.
Recommended Scenarios: Requires curved shapes, reusable, height under 4.5m. Not recommended scenarios: Only need straight structures, single use, extremely budget-sensitive.
Frequently Asked Questions
Q1: How much slower is the setup of curved frames compared to straight ones? A: The first setup (18m² booth) takes about 1-2 hours longer; after repeated setups, the gap narrows to 0.5-1 hour. The required workers and tools are the same as for straight frames.
Q2: Can curved frames be mixed with straight frames from other brands? A: Not recommended. The Fast62 curved component is specifically designed for 62mm profiles and is not compatible with slots or connectors from other brands.
Q3: How is the fabric fixed on the curved frame? A: Same as the straight frame, using matching silicone strips or magnetic strips for fixation. The curved part needs to be cut according to the actual curvature, and it is recommended to have it made by a professional team.
Q4: Can the curved frame support double-sided display? A: Yes, fabric slots need to be reserved on both sides of the curved component. Inform us of the requirement during design, and we will provide the corresponding connector solution.
Q5: If I want to switch back to a straight frame later, can the curved components be used independently? A: Yes, it is possible. Curved and straight components use the same connecting brackets and can be freely combined, but the curvature of the curved components will not disappear. It is recommended to reuse them as curved assemblies.
