埃及采购需求：螺栓、螺母、垫圈、膨胀锚栓、螺纹杆和螺柱、螺钉

I'm looking for a supply of several galvanized components including threaded rods, nuts, washers, and slotted channels. Specifically, I need the threaded rods in a standard length, and the nuts and washers should fit accordingly. Additionally, the slotted channels must meet set dimensions, ensuring they are robust enough for my requirements. All items should be galvanized, and I prefer them to be silver electroplated following ASTM standards. It's crucial that the electroplating is at least 40 MICRONS thick to ensure durability against corrosion. Please provide your best pricing and lead time for these products, as well as any relevant details regarding your manufacturing capabilities.
