斯洛伐克采购需求：液压缸管/珩磨管，无缝冷拔钢管，镀铬棒材，液压缸

I'm looking for precision honed tubes that meet specific dimensions. Ideally, I need a tube with an inside diameter of 12 inches and an outside diameter of 14 inches, with a length of 6 meters. The material should be suitable for structural applications, specifically a high-strength steel grade. Could you provide details on your availability, pricing, and lead times for these specifications? If there are any bulk order discounts or additional services, I'd love to hear about those as well. Looking forward to your prompt response.
