Hpa majaw nga yang, n-gun ja ai hpun npu, engineering hpun npu, laminate npu, hte multi-layer npu npu ngu ai npu npu ni hpe gat lawk hta madung hku nna masum nga ai. Shawng nnan na amyu lahkawng gaw, htunghking hku nna n-gun rawng ai npu npawt amyu ni hku nna grau nna-chye ai amyu ni rai nga ai. Multi-layer composite npu gaw, shawng na lahkawng hta grau nna gram lajang da ai, laminate npu a n-gun hpe hkam sharang lu ai hte, engineering hpun npu a n-gun hpe hkam sharang lu ai, n-gun n-gun hpe hkam la lu ai. Shi gaw grai sawng ai makau grup yin masum (shawa shara, npu kaw katsi ai shara, hka lim ai shara) hta grai kaja hkra galaw lu sai. Lang na matu hte gram lajang na matu ra kadawn ai lam ni mung n bung ai.
Engineered hpun npu gaw, n-gun ja ai hpun npu a tsawm htap ai, shingra tara hkam sha lam, kaja ai insulation ni hpe, n-gun ja ai hpun npu a n kaja ai lam ni, shrinkage a majaw n-gun yawm mat ai hte n-gun yawm mat ai zawn re ai ni hpe kayau kaya galaw da ai. Daini aten hta, grup yin hpe grau nna jahten sharun ai lam n byin na matu, mungkan ting na mungdan ni gaw nam maling sutgan ni hpe makawp maga ai lam hpe grai myit maju jung nga ma ai, engineering hpun npu gaw, ngang kang ai hpun npu hte shingdaw yang, n law htum hpun sutgan ni hpe makawp maga lu ai. Dai hta n-ga, engineering hpun npu hpe mung jung na matu loi ai, madung hku nna gaw subfloor n ra ai. Raitim, level subfloor langai mi ra ai.
Engineering hpun npu hpe madung daw masum hku nna bai garan mai ai: masum-layer engineering hpun npu, multi-layer engineering hpun npu, plywood npu. Nta hpe mawn sumli ai hta hpun npu hpe masum-layer hte multi-layer engineering galaw da ai hpe grau lang ma ai. Masum-layer engineering hpun npu hpe hpun n-gun ja ai hpun masum hpe cross-laminated galaw nna galaw ai. Lahta na layer hpe -madang tsaw ai hpun n-gang ni hte galaw da ai rai nna, law malawng gaw ash, birch, beech, oak, maple, cherry zawn re ai hpun amyu ni kaw na rai nga ai.

High-density engineered hpun npu gaw grau ngang kang ai, grau kaja ai hku n-gun n rawng ai, grau loi ai hte grau shim lum ai hku jung lu ai, manu mung n law ai, raitim shi a lagaw npu na hkam sha lam gaw loi mi n-gun n rawng ai.
Multi-layer n-gun rawng ai npu gaw, hpun n-gun rawng ai npu hpe grau kaja hkra galaw ai re. Solid wood composite flooring a akyu ni hpe bang da ai shaloi, ngang kang ai lam hte n-gun n rawng ai lam hta grai rawt jat wa sai. Dai hta n-ga, grai sawng ai makau grup yin masum (shawa shara, npu npu na katsi ai shara, hka lim ai shara) hta grai kaja ai hku galaw lu ai majaw, dai ni na aten na nta kata hkrang shapraw ai lam hta mung, loi loi hte grau grau jai lang wa nga ai.
