stage lighting truss

Stage lighting truss (often just called a truss) is a modular, lightweight, rigid aluminum framework used extensively in live events (concerts, theater, corporate events, festivals) and installations to safely suspend lighting fixtures, speakers, video screens, scenery, and other production equipment above a stage or audience area. Purpose & Function: Support: Provides a strong, stable structure to hang heavy lighting fixtures (par cans, moving heads, LED panels, strobes), speakers (line arrays, subwoofers), video walls, projectors, scenic elements, banners, and rigging hardware. Positioning: Allows technicians to precisely position equipment at various heights and locations over the stage or audience (e.g., front-of-house positions). Cable Management: Often incorporates features or allows for the neat routing and securing of power cables, data cables (DMX, Ethernet), and audio cables alongside or within the truss structure. Safety: Engineered to safely bear significant loads when properly installed and rated. Lighting truss is a fundamental component in the world of event production and stage design. Lighting Truss often referred to as stage truss. This versatile structure offers lighting designers and event planners the freedom to hang lighting fixtures and various staging elements precisely where they are needed. What is Stage Lighting Truss? Lighting truss comes in various lengths to suit different applications. The most common truss lengths are 1m-4m allowing for flexibility in design and setup.   Common Types:   1. Ladder Truss: Simple, lightweight truss with two parallel chords connected by vertical or angled rungs. Primarily used for lightweight applications like drapes, banners, or very small fixtures. Not suitable for heavy speakers or complex lighting. 2. Triangle Truss: Triangular cross-section. Lighter weight than box truss of similar size but still strong. Good for lighter lighting rigs or as "ladder" truss for vertical structures. Often used for roof structures or where weight is a major concern. 3. Square Truss: The most common type. Hollow square or rectangular cross-section. Offers high strength and torsional rigidity, making it ideal for hanging heavy loads like large speaker arrays or complex lighting rigs. Comes in various widths and heights (e.g., 12"x12", 15"x15", 20"x20", 12"x24"). 4. Circle Truss: Made from curved sections forming a circle or arc. Used for special effects, circular video screens, or unique scenic elements. Lighting truss systems can be customized and accessorized to meet specific event requirements. Various connection methods and accessories are available to enhance functionality and aesthetics.  Bolt truss means Plated connection, Fork truss means pin and fork connection and Spigot truss means Conical connection.     In conclusion, lighting truss is an indispensable tool in the world of event production and stage design. Understanding its various types, applications, and safety considerations is essential for creating visually impressive and safe event experiences. Whether you're planning a concert, theatrical production, or any event that requires precision lighting and audio setups, lighting truss is a versatile solution that can be tailored to your needs.

We all know that aluminum is widely used in life and industry, and there are many types of surface treatment methods for aluminum, usually including anodizing treatment, chemical conversion treatment, micro-arc oxidation treatment, electroplating treatment, electroless plating treatment or surface organic coating (powder spraying or painting) and so on. The Aluminum Black Truss most widely used process is anodizing and Power painting. 1. Prevent corrosion of aluminum products on the aluminum surface can be used as a protective layer. The oxide film obtained by anodizing aluminum in chromic acid solution is dense and has good corrosion resistance. The pores of the oxide film obtained from the sulfuric acid solution are larger than the former, but its film layer is thicker and the adsorption capacity is very strong, and its corrosion resistance is also very good if properly filled and sealed. In particular, chromic acid anodizing is particularly suitable for anodizing rivets and welds. That's why more and more people choose Stage Aluminum Truss for events. 2. As a hard wear layer By hard anodizing aluminum and aluminum alloys, a thick and hard Al2O3 film layer can be obtained on its surface. This film layer not only has high hardness and thickness, but also has low roughness. In sulfuric or oxalic acid solutions, a hard and thick oxide film can also be obtained on aluminum products by anodizing. The porous thick oxide film can store lubricating oil, so it can be effectively applied to aluminum products that work in friction states, such as engine cylinders and pistons of automobiles and tractors, which can greatly improve their wear resistance after anodizing. 3. As a base layer for spray paint Due to the porosity and good adsorption capacity of anodized film, it can be used as a base layer for spray paint and other organic films, so that the paint film and organic film are firmly combined with the product, thereby increasing its corrosion resistance. 4. As the bottom layer of plating Before electroplating, aluminum and aluminum alloy products must be applied to the bottom layer before electroplating. There are many ways to apply the bottom layer to the surface of the matrix, in addition to electro-galvanizing, galvanization, and electroless nickel plating, anodizing treatment is also one of the important methods.

No matter how gorgeous the stage effect is, it also needs a reliable Truss Structure to ensure it, and as a Stage Structure, it accounts for a large proportion and has the highest safety requirements, that is, the Aluminum Lighting Truss hanging above people's heads, especially the slightest joke. Its quality is directly related to the success of the performance or exhibition, but also related to the safety of relevant personnel, often heard in some performances or exhibition activities have performance accidents, then it is very necessary to have a certain understanding of this product, in order to better choose the Aluminum Lighting Truss product that suits you.   1) Judge from the Aluminum Raw Material: Aluminum alloy 6063, 6005, 6061 and 6082.   1. 6063 and 6005 Colloquial: The surface of agricultural aluminum turns black after contact with rain and air for a certain period of time. It belongs to the relatively low-end material. 2. 6061 Colloquial: Why is industrial aluminum called industrial aluminum, it is because it has better corrosion resistance and good weldability. In the T6 state, the Wechsler hardness is 12 degrees. 3. 6082 colloquial: Aviation aluminum Because 6082 is a new alloy, the Wechsler hardness is 15-17 degrees in the T6 state, and the composition is similar to 6061, which is an upgraded version of 6061, but because of its better performance, it is very popular in Europe, because the tensile strength is about 10-18% higher than that of 6061, and at the same time, because the copper composition is reduced, there is better corrosion resistance, but it does not lose any extrusion properties and anodizing reaction. Copper in 6061 is used as a reinforcing phase, and chromium is used for recrystallization control. The copper content in 6082 is reduced, and manganese is used for recrystallization control.   2)Judge from the design process First of all, we must realize that the Stage Structure is a kind of Aluminum Structure of the building. Therefore, one of the characteristics of designing Aluminum Structures is to use as little aluminum as possible and use thin-walled structures, which requires aluminum alloys to have excellent corrosion resistance and process properties. Generally speaking, the wall thickness of the bearing structural parts is 1.5-3mm, and there is no strict restriction on the enclosure structural parts. When designing the aluminum structure of the building, attention should be paid to the characteristics of the elastic modulus of the aluminum alloy semi-finished product, to prevent deformation, and to ensure the overall and local stability of the structural parts. When designing Aluminum Structures, attention should be paid to the rationality of the building structure.   How to Design process discrimination ?   1. Pay attention to controlling the weight of the Aluminum Lighting Truss, not the heavier the better, especially in some unnecessary structures to thicken the material, one is a waste of cost, and the other is to weaken the bearing capacity of the truss itself. 2. It is to avoid the design of destroying the profile itself on the Aluminum Lighting Truss to ensure the integrity of the welding circuit. 3. Although the name is called the sealing sheet, it actually needs to be stuffed into the main pipe, so as not to destroy the welding between the port and the main pipe. This will enhance the stress strength of the truss itself; At the same time, during use and transportation, the supervisor of the cross street can avoid the situation of change of heart and depression caused by collision, which may cause potential safety hazards and unsightly situations.   3) Judge from the welding process The production characteristics of Aluminum Structures are: they must be produced in specialized workshops or factories; In every link of production parts and structure, attention must be paid to maintaining the switch and surface state of the material; Semi-finished products with special sections should be used to reduce the amount of structural welding and processing, with the aim of enhancing the stability of materials and structures. Generally speaking, high-quality Aluminum Truss welding is fine, the welder is disciplined, the welding path is stacked into a fish scale stacked state, the size is accurate, and the connection hole will not be aligned or not aligned with the accessories after the product is formed.

Aluminum Lighting Trusses are essential in stage and event setups for supporting lights and equipment.   Lighting trusses are structural frameworks used to support lighting fixtures, speakers, video screens, and other production equipment for events, concerts, theaters, and installations. They come in various types primarily distinguished by their cross-sectional shape and structural design, each suited to different applications, load capacities, and aesthetic needs.   Below a breakdown of the main types:   Box Truss (Square Truss): Structure: Features a square or rectangular cross-section formed by four chords (top, bottom, and two sides) connected by diagonal and/or vertical webs (lacing). This creates a closed, box-like structure. Characteristics: Offers the highest strength-to-weight ratio and torsional rigidity (resistance to twisting) among common truss types. Excellent for spanning large distances and handling heavy point loads. Common Sizes: 200*200mm/290*290mm/400*400mm/520*520mm (referring to the width/height dimension). Applications: Overhead rigging (main lighting positions, flown arrays), large stage roofs, heavy speaker hangs, structures requiring maximum strength and stability. The most versatile and widely used type for professional applications.   Triangular Truss: Structure: Features a triangular cross-section formed by three chords connected by diagonal webs. The chords are typically arranged with one at the top and two at the base. Characteristics: Strong and lightweight, though generally not as rigid torsionally as box truss. Easier to handle and rig than larger box truss. Often has a lower profile. Common Sizes: 290*290mm/400*400mm (referring to the base width or height). Applications: Touring applications (lighter weight), ground-supported towers, delay towers, roof structures, scenic elements. Popular for its balance of strength and portability.   Ladder Truss: Structure: Features a simple, open cross-section resembling a ladder. Typically consists of two parallel top chords and two parallel bottom chords connected by vertical or near-vertical webs (rungs). Lacks diagonal bracing within the cross-section. Characteristics: Lightest and least expensive type. Easy to handle and assemble. Offers good strength in the vertical plane but has very low torsional rigidity and lower load capacity compared to box or triangular truss. Primarily designed for ground use or very low-height flown applications with minimal load. Common Sizes: 290mm/400mm (referring to the height/depth of the truss section). Applications: Ground-supported structures (goal posts, small roof structures, trade show booths), cable bridges, lightweight scenic elements, very low-overhead applications with minimal lighting. Not suitable for significant overhead rigging.   Circular Truss (Pipe Truss, Curve Truss): Structure: Features a circular or near-circular cross-section. Can be constructed similarly to a box truss but bent into a curve, or sometimes built using a lattice of tubes forming a circular profile. Characteristics: Primarily chosen for its aesthetic shape rather than maximum structural efficiency. Allows for creating smooth curves and circles. Load capacity varies significantly depending on the specific design and diameter. Common Sizes: Defined by diameter (e.g., 12", 16", 20", 24", 30", 40", etc.). Applications: Creating circular lighting rigs, curved scenic elements, archways, circular video screens, installations where a curved shape is desired.   Key Factors Influencing Choice Beyond Type: Material: Almost all modern event truss is made from aluminum alloy (typically 6061-T6 or 6082-T6) for its excellent strength-to-weight ratio and corrosion resistance. Older or very heavy-duty industrial truss might be steel. Ground Support vs. Flown: Some truss types (especially ladder truss) are primarily designed for ground support using towers or legs. Box and triangular truss are commonly used both flown (suspended from ceilings/structures) and ground-supported. Always check manufacturer specifications and load ratings. Load Rating: Critical factor! Truss is rated for UDL (Uniformly Distributed Load) and MPL (Maximum Point Load). Exceeding these ratings is extremely dangerous. Accessories: Corner blocks, spigots, base plates, casters, hoists, and clamps are essential for assembly, support, and rigging.   In summary: Choose Box Truss for maximum strength and overhead rigging, Triangular Truss for a good balance of strength and portability (especially touring), Ladder Truss for simple ground-supported structures, and Circular Truss when a curved aesthetic is required. Always prioritize safety by adhering strictly to certified load ratings and using qualified riggers.
