✓ Palang (framework accessories)

Palang is a device for lifting and lowering hanging objects from above, which is popularly applied in many types of works and certainly including the event industry. It helps to pull the truss frame on the roof of the stage, the canvas house up high. Many people also call Palang with some other names such as: Winch, pulley. Palang is divided into 2 types: electric hoist, chain hoist.

  • Chain hoist (Hand winch)

Chain hoist makes lifting and lowering objects easier than ever, does not take too much effort, helps to reduce accidents during the installation of stage, canvas and saves costs. One end of the hoist is fixed to the speculum above the top of the truss post, the other end has an iron chain, with a large capacity. The pulley system helps pull the stage truss frame, the canvas roof slides up through the wheel sliding cage.

✔ Compare aluminum truss frames and iron truss frames

✓ Aluminum truss frame

Aluminum truss frame is a truss frame made from aluminum alloy material. Aluminum alloy is a very important product line in all products manufactured from aluminum. The alloy of aluminum and aluminum ranks second after steel in terms of production and application in life. It can be seen that aluminum alloy has properties to be suitable for many different uses, especially used as a material in construction.

There are 2 types of aluminum alloy used by Viettruss to make aluminum truss frames:

T6061 Aluminum Alloy : the most durable and versatile aluminum alloy series. This aluminum alloy is a general purpose alloy with high strength, corrosion resistance and good weldability.

T6082 aluminum alloy : This alloy has good mechanical properties, is strong, hard, resistant to strong impact and has high wear resistance, can be welded and machined and shaped.

✓ Iron truss frame

Iron truss frame is a type of frame made from iron material. It has poorer thermal conductivity than aluminum and is more malleable than aluminum. Truss frames made from iron are much heavier than truss frames made from aluminum.

In terms of corrosion resistance, aluminum truss frames are better than iron. Especially with the changing seasons like in Vietnam, the iron truss frame is easily corroded when left in the air for a long time. Unlike iron, the truss frame is made from aluminum which is almost completely non-corrosive and retains its shine like new.

Aluminum truss frames meet all requirements for aesthetics, curvature, and weight, so it is understandable that aluminum truss frames are more commonly used in today's market.

✔ Code table and how to read truss frame parameters

Truss modules are often connected with each other by connectors or bolts to create a large truss frame, serving to install the stage as a frame for hanging lights (poles), stands or mobile canvas houses. Because the nature of the installation and decoration of event stages and tents is very different, it requires a variety of truss frames to suit each type of event or canvas. There are 1-sided, 3-sided, 4-sided truss frames with many different sizes and structures (The effect of the crossbar is to support and facilitate climbing and installation). Because of the variety of products, Viettruss decided to set up product codes to unify reading, easy in production, product identification as well as customers easily understand the product they want. want to buy or rent.
