Modular Quick-Assembly Raya Truss

As a modular quick-assembly support structure, it is widely used in scenarios such as Concert Stage construction, lighting Truss suspension, temporary grandstands, and construction projects. The material selection and specification design of Raya scaffolds must match load-bearing requirements, usage environments, and construction efficiency. The specific classifications are as follows:

I. Core Materials of Raya Scaffolds: From Basic to High-Strength Options

The material of a Raya scaffold directly determines its load-bearing capacity, corrosion resistance, and service life. Mainstream materials are divided into two major categories: steel and aluminum alloy, which should be selected based on scenario needs:

1. Steel Materials Raya Stage System

Steel is the most commonly used material for Raya scaffolds, with core advantages of high rigidity and large load-bearing capacity. It is suitable for heavy-load scenarios Raya modular stage system. The main subdivided types are:

Q235 Low-Carbon Steel

As the basic material in the industry, it has a yield strength of 235MPa and a tensile strength of 375-500MPa. It has good weldability and ductility, and can meet most medium-to-low load scenarios Raya portable stage.

Its surface is usually treated with hot-dip galvanization Raya quick-assembly stage to improve rust resistance, making it suitable for dry or slightly humid indoor and outdoor environments Modular Quick-Assembly Raya Truss.Disadvantage: Heavy self-weight Modular stage platform, requiring more labor for handling and construction.

Q355 Low-Alloy High-Strength Steel

As an upgraded material, it has a yield strength of 355MPa and a tensile strength of 470-630MPa. Its load-bearing capacity is 30%-50% higher than that of Q235 steel, making it suitable for heavy-load scenarios Modular Quick Assembly Truss System.

Its surface is also mainly hot-dip galvanized; some high-end products are treated with powder electrostatic spraying Lightweight Quick Assembly Truss, which has stronger weather resistance and can be used in humid environments such as rainy areas and coastal regions.

Feature: Under the same load-bearing requirements, it can reduce the number of vertical poles, lower construction density, and improve space utilization.

2. Aluminum Alloy Materials 

Aluminum alloy Raya scaffolds are mainly made of 6061-T6 or 6082-T6 industrial aluminum alloy, with advantages of lightweight, corrosion resistance, and easy handling. They are suitable for scenarios sensitive to construction efficiency and self-weight :

6061-T6 Aluminum Alloy

It has a tensile strength of approximately 310MPa and a yield strength of approximately 276MPa, with a density of only 2.7g/cm³ . Each vertical pole weighs about 1.5-2.5kg and can be handled by one person. Its surface is treated with anodization , which is acid and alkali resistant, corrosion resistant, and free from rust concerns. It is suitable for long-term outdoor use or coastal high-salt-fog environments.

Disadvantage: Its load-bearing capacity is lower than that of steel of the same specification, so it is not suitable for heavy loads. 6082-T6 Aluminum Alloy It has higher strength than 6061-T6 , and its load-bearing capacity is close to that of low-specification steel. At the same time, it retains the advantage of lightweight, making it suitable for scenarios requiring "medium load + convenient construction" . It is the "high-strength model" among aluminum alloy Raya scaffolds.

II. Classified by Components 

A Raya scaffold consists of components such as vertical poles horizontal poles, diagonal poles, disc joints, and bases/top supports. The specifications of each component must be uniformly matched .
