卡塔尔采购需求：型钢、金属梁、结构钢、钢型材、钢托梁、钢柱

I'm looking for a specific type of beam for a project. I need a profile that is either an I-section or H-beam, with dimensions of 150mm in width and a thickness of 5mm. The length required for each piece is 19 meters. Could you please provide information on availability, pricing, and lead time for this order? Additionally, if you have any recommendations or alternatives that might suit my needs, I'd appreciate your insights. Looking forward to your prompt response so we can move forward with this procurement.
