莫桑比克采购需求：护栏，高速公路护栏，W梁护栏，护栏，护栏道闸，防撞护栏

I'm interested in obtaining a quote for sandwich roof sheets for an upcoming project. Specifically, I'm looking for 60 units of each size: one set measuring 1m x 3.8m and another set at 1m x 4.2m. Additionally, I would like to know if you offer sheets with a thickness of 30mm. If that's not available, please provide a quote for those with a thickness of 50mm instead. Could you also include any relevant details about lead time, available colors, and payment terms? Your prompt response would be appreciated as we aim to finalize our procurement decisions soon. Thank you!
