I am reaching out to request a quotation for a substantial project involving a steel structure measuring approximately 20,000 m² intended for a site in Costa Rica. We are looking for comprehensive pricing options, including details on material specifications, lead times, and any potential customization available to meet our project requirements. In addition, it would be great if you could provide insights into your company's experience with similar projects, particularly any relevant certifications or quality assurance processes you have in place. As we plan ahead, understanding your production capabilities and logistics for delivering to Costa Rica will be essential. Thank you, and I look forward to your prompt response.
