We are currently in the market for a rooftop helipad platform with a diameter of 20 meters. Our project requires a structure that meets specific safety and usability standards, as it will be used for both emergency and routine helicopter landings. We are looking for a solution that can withstand various weather conditions and is compliant with aviation regulations. In addition to the basic specifications, we'd appreciate details on the materials used, weight capacity, installation process, and any customization options available. Please include your estimated lead time and pricing information, along with any relevant certifications your products hold. We're eager to explore potential collaboration and look forward to your prompt response.
