Application Scenarios
Square tube structural profiles are commonly used for platform and walkway supports, handrail frames, equipment supports and large-span frames where strength and corrosion resistance are required. In corrosive environments such as chemical, water treatment and electroplating, they can replace some traditional metal profiles. Contact us to discuss suitable applications based on your specific working conditions.
Selection Guide
When selecting, first confirm the cross-section dimensions (A×B) and wall thickness (T1, T2), and evaluate them together with span, load type and support method. Different resin systems and fiber content affect mechanical performance. For specific specifications and load-bearing recommendations, contact us for detailed specifications and quotations.
Product Advantages
The square tube is pultruded from glass fiber reinforced material with resin, featuring light weight, high strength, corrosion resistance, insulation and ease of cutting and processing. The surface can be treated in different ways as needed to suit various installation methods. To learn about specific performance and process details, contact us.
Inquiry Guidance
For specific cross-section dimensions, wall thickness combinations or bulk supply solutions, contact us for detailed specifications and quotations. Please provide the required dimensions, quantity and operating environment, and we will recommend a suitable product solution accordingly.
