I'm looking to source some hexagonal steel poles with specific dimensions. We need poles that stand at a height of 6 meters, designed with a diameter suitable for our applications. Additionally, I'm interested in obtaining poles that include cantilever extensions of varying lengths, specifically at 5m, 6m, 8m, and 10m. It would be great if you could provide detailed specifications, including material quality, weight, and any available finishing options. Also, I'd appreciate receiving pricing information, lead times, and any minimum order requirements you might have. Please let me know if there are any certifications or standards that these products meet as well.
