WHY PEOPLE CHOOSE ALUMINIUM TRUSS RATHER THAN IRON TRUSS
Aluminum truss is a important structural material for event stages, It plays a main role in the truss works. Above all, safety comes first in all around a event, especially for the stage, thus the quality of the truss is the key point. Why in these days, more and more event organizers and truss rental companies choose aluminium truss rather than iron truss? Here, I gathered some information and summarized its advantages in following aspects :
1. Aluminum truss has excellent corrosion resistance and durability
Comparing with the traditional stage material such as iron, aluminum truss is made of 6061-T6 industrial aluminum material, which has excellent anti-corrosion characteristics, and the service life is much longer than that of iron truss. In general, aluminum a set of truss system can be used for about 10 to 20 years.
2. Aluminum truss has excellent compression capacity
The aluminum truss itself is well-made, and its load-bearing and compression resistance is very good. The average aluminum truss can bear more than 600kg. It can fully meet the needs of large-scale lighting and sound equipment such as various performance stage construction and celebration stage construction. Also, it can be customized design and manufactured into any truss types those truss company prefer, such as roof truss, circular truss, heart truss, dome truss, and etc.
3. Aluminum truss has good quality and it is light weight
Aluminum truss is made of aluminium ally, it is half lighter than the traditional iron truss, which reduces the burden for the stage builders who rely on manual work, so that the stage hoisting and stage erecting process and transportation shall save much cost and labor in the stage projects.
4. Aluminum truss has silver white color
Usually, Aluminum truss is used for concerts,wedding ceremony, indoor parties, events, gatherings and functions, which people shall take part in are very picky on the aesthetic feeling, comparing brown and gray iron, Aluminum truss looks more modern stylish with its silver white color and smooth simple shape.
Trussed Tower – Overview, Applications, vs. Lattice Framework
Based on a triangular shape, a truss tower is a structure designed to support heavy loads. Steel truss towers provide the large majority of tower installs today. Many years ago wood truss towers saw common use but have since been surpassed by their steel counterparts. In this article, you will learn what a trussed tower is, trussed tower applications, and the differences between a trussed tower and a lattice framework.
What Is A Trussed Tower?
A trussed tower is a freestanding vertical structure used to support heavy loads. The building traditionally has three sides. In some cases and applications, there are four sides. Compared to other support structures, a trussed tower needs fewer materials to carry heavy loads. It thus makes for an efficient and practical choice for engineers.
There are three essential elements of a trussed tower. These are the lower horizontal chord, the upper horizontal chord, and the bracing between the chords. The lower flat and upper horizontal chords carry tension and compression, respectively. The bracing opposes shear force. The truss web provides sloped and vertical segments that connect the chords. Additionally, the chords also stabilize each other.
Trussed Tower Applications
Different applications have different designs and standards. This difference lies in weight load capacity and environmental factors.
Electrical Transmission Towers
A transmission tower, also known as an electricity pylon, is a tall structure that supports an overhead power line. The more cost application is high-voltage transmission lines that transfer bulk electric power from producing units to electrical substations. These towers come in a wide variety of shapes and sizes. Typical height ranges from 15 to 55 m (49 to 180 ft). In addition to steel, other materials such as concrete and wood may be employed.
Lower-voltage sub-transmission and distribution lines that transmit power from substations to electric customers usually use traditional circular utility poles constructed from wood.
CONCERT STAGES: PROS AND CONS, DIFFERENT TYPES, AND MORE
Lots of people love going to concerts! The excitement, the anticipation, the energy. But something that a lot of people don’t think about, and you’re probably realizing right now, is that there’s a lot of work that goes into planning for a concert. One of the first things you have to consider when planning a concert is the venue, and one of the most important considerations to make is the stage. And it turns out that there are tons of different types of stages! The shape, the space, and the acoustics all have a big effect on the overall experience that your performers and audience will have.
Great for smaller venues.
Simple to set up and take down.
Not as much control over the acoustics, so the music may sound different depending on where your venue is.
End stages are fantastic for creating a raised spot for your musicians to play just about anywhere. They are really easy to set up as the stage and the scaffolding can be created off site and built out pretty much anywhere you need a stage. The flexibility of where you can set these concert stages is truly what makes the end stage a great choice!
Portable Stages - The Science Behind Staging
A stage is an integral part of any mass gathering. A wedding, a concert, a dance show and anything related to entertainment requires a stage. A bulky stage can be very difficult to move to another location. But a portable stage can be dismantled and moved to any desired location at a short notice.
Durability of such stages might pop in. But the science of staging has advance to a great level and hence durability and style, both are taken care of in these new age stages. Anything portable needs to be light weight. Hence Aluminium is used a lot in making stage's skeleton over which designer platforms are use. The platforms can be of any material from glazed wood to light studded glass fibre.
Specifications of a Typical Portable Stage
Strength: A combination of plywood or birch wood with aluminium gives enormous strength to the stage and wouldn't collapse that easily.
Versatility: The staging can be done with different set of patterns for different purposes.
Easy assembling: The assembling is far easy in mobile stages for easy usage.
Storage: Upon dismantling the frame can be folded into thin strips of aluminium and the boards can be simply stacked over on another and stashed away for later use.
Mechanism Involved in a Portable Stage
1:Assembling a stage involves the following steps:
2:Aligning the basic skeleton made of durable aluminium.
3:Each separate skeleton is assembled to the next such frame using multiple clamps
4:The height of this frame work can be changed using screws.The platform is place on the grooves of the legs of the frames
5:These clamps increase the stability and weight carrying ability of the platform that will be placed upon this aluminium frame work of skeletons,The platform itself is a multiple structure, each segment placed separately on the frame work.
6:Other decorative accessories can be added to the stage once this basic alignment is completed.
Spigot Truss and Bolt Truss
By definition, a truss is a framework, which consists of rafters, posts, and struts, and allows to support different structures and is widely used in audio and lighting field. According to Engineering, truss is a body that "consists of two-force members only, where the group of people who has organized so that the assembled as a whole and behaves like a single object". A ‘two-forced member’ is formed by components where force is applied in two points. There are two main types of truss, spigot truss (pin truss) and bolt truss.
Spigot truss is made up of aluminum alloy (6082-T6) and best used for live stages, theaters, exhibition booths, weddings and more. It is rust-proof, light in weight and can handle a high load capacity. Spigot truss is more popular and easier to arrange than the bolt truss and is easily transportable.
Bolt truss is made up of aluminum alloy (6082 – TC) and is also used for events, concerts, weddings, exhibition booths and more. It is similar to spigot truss where it is used for hanging lights, audio, speakers and more.
In all reality, there is not much of a difference between the two. Bolt truss and Spigot truss are built differently with different ways to attach to another. One with bolts and the other with pins. Bolt truss provides more space to add to the truss without as many cross-members as spigot truss. Spigot truss has moments where pins get stuck, or something wasn’t tightened enough and it caused the pin to get stuck where the bolt truss is attached easily with the bolts and a wrench. Either type will do the job, choosing which is considered better is based off of personal preference.
