印度采购需求：螺旋管、特种管、镀锌管、不锈钢、不锈钢无缝管、不锈钢板

I would like to inquire about a specific order for steel materials. I'm looking for two tons of square steel sections with particular dimensions: 75 mm by 75 mm and a thickness of 10 mm, with a total length of 2 meters. These products should be of grade Q235, suitable for our sample needs. Could you please provide detailed pricing and availability information? Additionally, if you could share any relevant specifications or certifications related to the materials, it would be greatly appreciated. Looking forward to your prompt response so we can move forward. Thanks!
