According to the directory, cross-beams can be made from structural steel, aluminum alloy, or carbon steel. The specific material grade (e.g., Q235B to Q355B) should be confirmed with the manufacturer based on your application.
The listed load capacity ranges from 5 to 50 tonnes for uniformly distributed loads. However, the actual capacity depends on the beam dimensions, material, and support conditions. Always verify with the supplier for your specific model.
Relevant standards include GB/T 1591 for material grades, ISO 1101 for straightness tolerance, ISO 8501-1 for surface preparation, and ISO 19840 for paint thickness. These are reference standards; confirm compliance with the manufacturer.
Consider the required span length, load capacity, beam height, flange width, web thickness, material grade, and operating environment. Also evaluate factors like temperature range and weight. Consult the manufacturer to ensure the cross-beam meets your structural and safety requirements.
