菲律宾采购需求：Thrie Beam、警卫、高速公路安全、道路护栏、车辆防护、安全系统

I'm looking for Modified Thrie beam guardrails equipped with robust modular posts. The top post should stand at 0.75 meters from the finished grade, featuring a baseplate at the bottom for connection with M25 bolts to the embedded bottom post. For the bottom post, it needs to be installed in reinforced concrete footings measuring 400mm x 400mm x 1200mm. Additionally, the bottom post should protrude 75mm above the top of the concrete footings, which will also have a baseplate to facilitate the connection to the top post. Please provide details on availability and pricing.
