Confirm the duct route先确认风管路线
Start with the intended portable air supply, exhaust or workshop ventilation route, then review the fabric sample.先确认便携送排风、车间通风或施工通风方向，再进入面料样品审核。

HM270 industrial flexible ventilation duct fabric.HM270 工业柔性通风风管面料。
A heavy 100% polyester 600D × 600D fabric direction for flexible ventilation duct development. Start with the fabric evidence, then verify coating, reinforcement, seams and the finished duct system for the intended environment.100% 涤纶、600D × 600D 的厚实工业面料方向，可用于柔性通风风管开发。先核对面料实物，再根据使用环境验证涂层、骨架、接缝和最终风管系统。

Fabric Review面料审核
Confirm the HM270 fabric evidence before discussing the finished duct.讨论成品风管前，先确认 HM270 面料证据。
When an industrial flexible duct project needs a clear 600D × 600D grey fabric direction and stable sampling reference, start the review here. The first image is a visual sample-card reference based on the real source record; the second and third show the current fabric appearance; the fourth is a generated detail reference grounded in the product photographs. The production image above is an enhanced visual reference based on a real production-site photograph. Final hand feel, surface treatment, thickness and processing compatibility require a physical swatch.当工业柔性风管项目需要明确的 600D × 600D 灰色面料方向和稳定询样参考时，可先从这里开始审核。第 1 张为根据真实样卡记录整理的视觉参考，第 2、3 张展示当前面料外观，第 4 张为基于产品照片生成的细节参考；上方生产图为基于真实生产现场照片的美化处理图。最终手感、表层处理、厚度及加工适配仍需通过实体样确认。

Check code and specification核对编号与规格
Keep HM270, 100% P, 600D × 600D and 300G together in buyer notes so every team reviews the same fabric direction.买方记录中应同时保留 HM270、100% P、600D × 600D 和 300G，避免团队对比不同面料方向。
Review documents separately资料单独审核
UL 94 VTM-0 is a source-label record. Confirm the current report, test method and specimen scope; it does not equal finished-duct compliance.UL 94 VTM-0 为原样卡记录，需核对当前报告、测试方法和试样范围，不等同完整风管合规结论。
