The installation of curtains over the stage is known as a drape stage truss. It serves various uses, such as supporting stage lighting, curtains, and ornamental elements like banners. There are also several materials and configurations available for the trusses.
Stage truss comes in various types, depending on the requirements of the event. These include:
Box-type trusses
This is the most rigid and strongest design because it can hold much weight. Threelatice work pieces are welded to create a box-like structure that supports heavy lighting, curtains, and sound systems.
Triangle trusses
These are the most prevalent type. The triangular shape provides tension and stability with lower material costs. They are compact, lightweight, and easy to transport. These are mostly used on small stages and as overheads for rigs. These are not recommended for heavy lighting because of their lightweight structure.
Hybrid trusses
Hollow structural sections are combined with lattice-style structure sections are combined and connected at chosen points to form a truss that is lightweight and yet strong. They are applied in situations where heavyweight items have to be hung but space is limited.
Tie-in trusses
They are designed to connect to one another and create a grid-like structure over the event area. This kind provides flexibility since more pieces can be tied in to meet the requirements and more can be taken out to enhance ease of installation and deconstruction.
Road case trusses
These are smaller and more compact than other trusses and also very portable. They are designed for transport and easy storage, making them ideal for smaller setups or rental companies.
Variable angle trusses
These are adjustable and allow various angles to be set during the event. This feature provides a lot of flexibility, allowing designers to create different configurations and adjust the setup based on specific requirements.
Many businesses and other organizations with the need for audiovisual equipment have applications for curtain-draped stage trusses.
Events and venues
Convention centers and theaters use trusses to hold stage lights, banners, and sound systems during performances in their auditoriums. They are heavily used since they are appropriate for bringing visual hierarchy and organization to areas where many mechanical components have to be integrated.
Exhibitions and trade shows
Trusses with curtains are extensively used in exhibitions and trade shows to create attractive booths and section off the venue into different displays, making it possible to showcase products in a more organized manner. The trusses can be used to create customized and organized designs for draped booths in order to attract many users.
Corporate functions
Many corporations use draped trusses for their events such as product launches, galas, and awards ceremonies. The flexibility in design of the truss makes it possible for corporations to create the atmosphere they desire, whether it is modernized or more traditional. Practicality is also added because drapes can be used to cover anything unattractive.
Retail displays
Retailers use drapes and trusses in stores to create attractive displays. The combination can be used to hold merchandise when the store is set up for special occasions or holidays. Also, draping can be used to create a softer, more luxurious appeal that impacts the customers.
Weddings and banquets
Trusses are heavily used in curtyan and truss wedding receptions and banquet halls. They can be used to transform unattractive objects or areas into classy looking objects. Around 90% of the centerpiece in a wedding or banquet hall is created through a draped truss.
Production companies
Rental companies dealing with audiovisual production will directly hang curtains on stage trusses for their clients to use. These companies will maintain a wide selection of styles, sizes, and materials of the trusses to enable them to service as many clients as possible. The companies also use trusses in their day-to-day operations; for example, they rent them out for use in their in-house productions.
Materials
Aluminum and steel are the most popular materials used for constructing trusses. Aluminum is light, easy to handle, and rusts very slowly. Hence, it is preferred for outdoor and temporary use. Steel is normally heavier and more difficult to handle, but usually, it is much stronger. Preferred for permanent installations.
Load capacity
This refers to the maximum weight the truss can carry without failure. Depending on the type and design, trusses have varying load capacities. It is critical always to pay attention to the suggested weight limit for this reason, particularly when placing large lights or sound equipment.
Span
The span of a truss is the distance it will cover without support. Because some are designed for greater spans, this characteristic is important for event designers. The longer the span, the more complicated it is to design without intermediate supports, which may restrict the area.
Connection type
Bolts, welds, and pins are generally the three most common connection types used in truss construction. Trusses with welded connections are strong, rigid, and firm, but the process of making them is too lengthy and expensive. Bolted trusses are more precisely fabricated since bolting allows for fine adjustments of the structure; however, these connections are not as strong as welded ones. Pinned connections are easy to combine and dismantle.
Finish
While aluminum will require hardly any finishing other than polishing to prevent rust, steel usually requires painting or electrocoating to prevent rusting. A black finish is used for theatrical purposes to prevent reflections of light.
Joint orientation
Great care should be taken when doing installations. This means that the joints should be located at the top of the structure T-type and bottom of the structure X-type to prevent oscillations. Older models will have horizontal joints, which then means that the joint orientation should be horizontal. These joints tend to be weak in tension - compression and shear. All of these types are aimed at resisting oscillations.
Tools required
Laptop or calculator, measuring tape, pen, or pencil to write with, safety glasses, rigging hooks, or clamps, adjustable wrench, a utility knife, and scaffolding are some of the tools needed.
Preparatory steps
Identify and take down basic concepts of the event. Draw several drafts that will guide the design. Determine the truss size and shape from the design. Use a measuring tape and rigging hooks while getting the measurements after reading the design. Double-check the measurements to eliminate any errors. Securely fix the truss at each joint.
Assembly instructions
Put together the pieces of the truss as per your design. Use bolted joints if you wish to adjust later on. Designate a part of the truss where heavy loads will be attached to ensure balanced load distribution.
Safety tips
Always put on safety goggles and gloves when working on the truss. Ensure the working environment is safe by clearing any unwanted items so as to reduce the chances of slipping or tripping. When working at greater heights, use scaffolding instead of ladders, and make sure the scaffolding is firm and has been secured properly.
A1: Stage trusses help support and organize the stage components like curtains, lights, and sound systems. They give a neat and useful support for heavy items placed on stage. They assist in holding lights and other components of the sound system.
A2: Aluminum and steel are the most preferred materials for making stage trusses. Because of its lightweight, aluminum is ideal for temporary use after installation. Steel provides more strength and can be used for permanent installations.
A3: A stage truss system is a support framework designed to hold equipment and decorations. It is used widely in events, theaters, and presentations to give organization and support for lights, sound, curtains, and other mechanical items.
A4: Regularly examine the stage truss for possible harm, dirt, and debris, mechanical components such as lights, and sound systems should be removed, and always check the stage truss before every use.
A5: The selection of a stage truss will depend on the event's span, load it has to support, and the materials for aluminum or steel. Flexible design ideas in draping also will assist in creating a style while providing more curtains to clothe the truss.
