The aluminum box truss archway is a popular choice for wedding ceremonies due to its sleek and modern design. Its sturdy construction and versatile nature make it an ideal choice for creating a beautiful and elegant entrance for the bride and groom. The archway can be adorned with flowers, fabric, or other decorations to match the wedding theme and create a stunning focal point for the ceremony. Its lightweight and easy assembly also make it a practical choice for outdoor venues. Overall, the aluminum box truss archway is a stylish and functional addition to any wedding ceremony.
3m Diameter Semicircular Truss
The upper part of the arch is formed from a 3m-diameter half-circle truss.
Because the semicircle has a radius of approximately 1.5m, combining it with the two 1m vertical straight truss sections creates an overall center height of approximately:
1m + 1.5m = 2.5m
This is the basic geometry of the finished wedding arch.
The curved section gives the structure a softer visual profile than a conventional square or rectangular truss entrance.
300×300mm Aluminum Bolt Truss
The archway uses 300×300mm aluminum box truss with bolt connections.
The same basic truss format is used for both:
Using matching truss dimensions allows the separate modules to form one continuous arch-shaped structure.
For buyers looking for other straight, curved, or customized aluminum truss configurations, DragonStage also provides Aluminum Truss products.
Two 1m Vertical Truss Sections
The lower sides of the arch use:
1m straight truss × 2 pcs
One straight section is positioned on each side beneath the curved semicircle.
This raises the semicircular section above ground level and creates the final approximately 2.5m center height.
The structure therefore does not require specially manufactured one-piece curved legs. It uses a simple combination of standard straight truss and curved truss.
500×500mm Base Plates
The current full configuration uses:
500×500mm base plate × 2 pcs
One base plate is installed under each vertical truss section.
The base plates provide the ground interface for the archway and make it possible for the structure to stand as a separate event display.
For related plates, connectors, bolts, and replacement components, see our Truss Accessories range.
The 500×500mm plates are the base size used for this product configuration. They should not by themselves be interpreted as a universal guarantee of freestanding stability for every decoration or installation condition.

Designed for Decoration
The truss itself provides the structural shape of the arch, while event decorators can use the frame as a base for different visual themes.
Typical decorative applications may include:
Decoration materials are not automatically included with the truss arch unless specifically listed in the quotation.
Typical Applications
This aluminum archway can be used for:
Wedding ceremony entrances
Wedding backdrops
Reception entrances
Engagement ceremonies
Event photo areas
Exhibition entrances
Corporate event decorations
Festival entrances
Product launch displays
Temporary decorative structures
Although the existing product name focuses on weddings, the structure itself is not limited to wedding use.
Its simple curved geometry can also be adapted for other decorative event applications.
Modular for Transport and Reuse
One advantage of this design is that the arch does not need to be transported as a complete 3m-wide assembled structure.
It can be separated into:
straight truss + curved truss sections + bases + connection hardware
for transport and storage.
This is particularly useful for:
that may use the same structure repeatedly with different decorations.
Custom Sizes Available
The 3m-wide × approximately 2.5m-high version is one existing configuration.
DragonStage can also manufacture customized truss arches with different:
Arch widths
Overall heights
Curved-truss diameters
Straight-leg lengths
Truss sizes
