Ahkyak ai hpaga lam hta npawt nhpang arung arai langai rai nga ai wire sumri hpe sharawt ai jak, elevator, hka lawng, lung seng htu ai jak ni hta grai lang ma ai. Shi a galaw shapraw ai ladat a ngang kang ai lam gaw, galaw shapraw ai arung arai a bungli galaw ai lam hte shim lum lam hpe hkrak hkra machyi shangun ai.
Wire sumri galaw ai lam gaw, -madang tsaw ai n-gang hpe lata ai kaw nna hpang wa ai, laksan hku nna, n-gun ja ai-carbon n-gang wire rod hpe lata la ai kaw nna hpang ai. Oxide scale hpe shaw kau na matu ntsa lam hpe tsi lajang ngut ai hpang, wire hpe htu ai lam hpe galaw hpang wa ai. Drawing pass law law hku nna, wire rod hpe kalang ta, hkrang shapraw da ai diameter na steel wire kaja de kalang ta htu shapraw ai. Ndai ladat gaw, dimensional hkrak ai hte ntsa lam a hkam kaja lam hpe lu la na matu, n-gun hpe grai ngang kang ai hku hkang lu na matu hte sau bang ra ai. Dai hpang, dai wire hpe lead bath quenching (sh) annealing zawn re ai nbung laru hpe galaw nna, shi a jak rung atsam hpe gram lajang nna, n-gun hte ngang kang ai lam hpe hkrak hkrak rap ra hkra galaw lu ai.
Hpang na lahkam gaw wire coating galaw ai lam re. Laksan lang na matu yaw shada ai hta hkan nna, galvanizing (hpyen n-gun hpe makawp maga na matu) shing nrai, polishing (n-gun kaba na matu) hpe lata mai ai. Dai hpang, coated wire hpe shi a hpang jahtum na diameter de bai gang je kau nna, kata na n-gun ni hpe yeng seng kau lu na matu hte hpang na shinggrup ai shaloi ngang grin ai lam hpe jat ya lu na matu pre-deformed galaw ai.
Twisting ngu ai gaw wire sumri galaw ai madung lam re. Structure ra kadawn ai lam ni hta hkan nna, n-gang wire langai (sh) law law hpe n-gang gang ai jak langai mi hta, n-gang gang ai jak langai mi hta, masat da ai maga de (left-hand or right-hand) hku shinggrup nna, n-gang gang ai jak langai mi hpe galaw ai. Dai hpang, dai n-gang ni hpe sumri pat ai jak langai a ntsa na central core hte rau bai shinggrup nna sumri langai byin tai wa hkra galaw ai. Twisting galaw ai shaloi, lay length, lay direction, tension ni hpe hkrak hkrak hkang lu na matu, n-gun n-gun ni hpe n-gun n-gun garan ai lam langai sha rai nna, n-gun n-gun (looseness) shing nrai, n-gun n-gun (structural defects) ni hpe koi lu na matu galaw ra ai.
Hpang jahtum na wire sumri ni hpe mungdan madang hte hpaga lam tara ni hpe hkan sa lu na matu, diameter shadawn ai, daw garan ai n-gun hpe chyam dinglik ai, torsion hte bending chyam dinglik ai lam ni lawm ai, grai sawng ai quality jep joi ai lam ni hpe galaw ra ai. Hpang jahtum, sau bang nna, shinggyin ngut ai hpang, dai arai hpe sa ya na matu jin jin rai sai.
Wire sumri ni hpe galaw shapraw ai hta, arung arai hpaji, jak hpaji, hte hkrak hkrak galaw shapraw ai hpaji ni hpe hpawng de da ai. Ladat shagu hpe shim lum ai, kam mai ai, hte -magam bungli galaw lu ai arung arai hpe shapraw lu na matu hkrak tup hkang zing ra ai.
