1×19 โครงสร้างลวดเหล็กตีเกลียว
ลวดเหล็กตีเกลียว(Steel Wire Strand)โครงสร้าง 1×19 หรือที่รู้จักกันในนามกายวาย สาย ยึดโยง
เป็นสายหลักในการใช้ ยึด โยง เสาไฟฟ้า เสาทาวเวอร์เสาส่งส่งสัญญาณ เสาโทรคมนาคม
ซึ่งขนาดของลวดนั้นจะแตกต่างกันไปตามขนาดของเสา
โดยมาตรฐาน กายวายนั้นจะเป็นลวดที่ผ่านขบวนการชุบกัลวาไนซ์ ป้องกันการกัดกร่อนและเพิ่มอายุการใช้งาน
ก่อนจะเลือกซื้อ ลวดกายวายต้องสังเกตุดูว่าลวดนั้นเป็น เกรด EHS (Extra High Strength) หรือแปลได้ว่าแข็งแรงเป็นพิเศษ
1×19 นั้นไมได้แตกต่างจาก โครงสร้าง 1×7
แต่หากเส้นผ่าศูนย์กลางของลวดใหญ่เท่าใด จำเป็นต้องเพิ่มจำนวณลวดเพื่อรักษามาตรฐาน
บ.สไปก้ามีประสบการณ์ในการจำหน่ายและให้คำปรึกษาการใช้งานมามากกว่า 20 ปี
ลวดเหล็กตีเกลียวของเรามีตั้งแต่ขนาด 25mm2 ถึง 185mm2 หรือขนาด 1.5mm ไปถึงขนาด 32mm
