印度采购需求：护栏，高速公路护栏，W梁护栏，护栏，护栏道闸，防撞护栏

I am looking for high-quality PUF boards suitable for roofing and wall applications. The boards should offer excellent thermal insulation, lightweight properties, and durability to withstand various weather conditions. Please provide detailed specifications, including dimensions, density, and fire resistance ratings. It would also be great to know about the color options and any certifications your boards hold. In addition, I'm interested in your pricing structure for bulk purchases, lead times for delivery, and any minimum order quantities. If you have product samples available or can share references from previous clients, that would be really helpful in evaluating your offerings. Looking forward to your prompt response to discuss this potential collaboration further.
