Plywood gaw screw- hpe grai kaja hkra hkam la lu ai atsam, n-gun kaba ai, ngang kang ai, nsen hpe n hkam la lu ai, katsi ai hpe n hkam la lu ai atsam ni hpe gumrawng nga ai. Bai nna, hka n-gun n law ai (10% hte 13% lapran) nga ai, galaw na matu loi ai, jai lang mai ai lam ni hta grau dam lada ai.
Plywood gaw solid wood hta grau ngang kang ai raitim, hka lim ai majaw hkra machyi chye ai. Dai majaw, gap ai aten hta shat gawk ni hte hka shin gawk ni hta shi hpe n lang ra ai.
Plywood galaw ai ladat hta, jak hte shingdaw ai hte lata hte shingdaw ai ladat ni lawm ai. Lata hte shingdaw ai hta hpun n-gang ni hpe plywood kata de lata hte bang ai. Hpun n-gang ni gaw n-gun n law ai hpe hkam sha ai majaw, n bung ai hku garan ginhka ai, gap kaba ai, nail-hkap la lu ai atsam n kaja ai. Dai hpe n mai htu ai rai nna, mawn sumli ai lam hta sub-project nkau mi a matu sha htuk manu ai, ga shadawn, hpun npu npawt nhpang hpe npu tawn da ai zawn re ai ni a matu sha htuk manu ai. Maga mi de, jak hte shingdaw ai shaloi, grau kaba ai n-gun hpe hkam sha ai majaw, n-gun n law ai, n-gun n law ai, lit -hkam lu ai atsam pyi nga ai, aten galu-lang ai shaloi, n-gun n rawng ai n-gun n rawng ai hkrang hpe lu la ai.
Arung arai n bung ai majaw, quality mung n bung ai. Plywood hpe gaw, n-gup magap a hkamja lam hte ntsa na n-gup magap a nsam hpe madung tawn nna, "grau kaja ai madang", "shawng nnan na madang", "htuk manu ai madang" ngu nna garan ginhka da ai. Company nkau mi gaw shanhte a board ni hpe Grade A, Double A, Triple A ngu nna masat da ai raitim, ndai gaw hpaga lam galaw ai lam sha rai nna, mungdan a madang hte n htap htuk ai; dai zawn masat da ai lam hpe gat lawk hta n mai galaw sai.
Plywood galaw na matu lang ai hpun amyu myu nga ai, dai ni gaw poplar, birch, pine, paulownia zawn re ai hpun ni rai nga ai. Dai ni hta na poplar hte birch hpun ni hpe kaja dik htum ngu sawn la ma ai, hpa majaw nga yang, shanhte gaw n-gun ja ai, grai n-gun ja ai, grai n-gun ja ai, n-gang-hkam lu ai atsam ngang kang ai, loi loi hte n-hten mat ai majaw re. Paulownia chyawm gaw grai n-gun n rawng ai hte n-gun n rawng ai, hka law law hpe hkap la lu ai, nail-hkap la lu ai atsam n kaja ai, hkyet mat na matu yak ai. Paulownia kaw na galaw ai board ni gaw lang ai shaloi hka lim mat ai shaloi, n-gun yawm mat nna, n-gun yawm mat chye ai. Pine gaw, ngang kang ai majaw, dip na matu yak ai, n kaja ai splicing structure, n kaja ai nail-hkap la lu ai atsam, n kaja ai deformation coefficient nga ai.
