Raws li cov duab ntawm lub hauv ntej nto thiab nws cov dej noo- pov thawj kev ua tau zoo, cov hniav gypsum board muab faib ua ob pawg: Ordinary board thiab ya raws - board resistant. Ordinary board muaj peb hom: Ordinary flat board (code P), zoo tib yam perforated board (code K), thiab zoo tib yam embossed board (code D). Moisture-resistant board kuj suav nrog peb hom: Moisture-resistant flat board (code FP), ya raws-resistant perforated board (code FK), thiab noo noo-resistant embossed board (code FD).
Qib zoo ntawm cov hniav gypsum board yog txiav txim siab raws li qhov ntev ntev thiab qhov tsis sib xws. Cov kev xav tau zoo tshaj plaws qhia tau hais tias sab pem hauv ntej ntawm cov hniav gypsum board yuav tsum tsis muaj qhov tsis xws luag uas cuam tshuam rau cov hniav zoo nkauj, xws li cov cua qhov, stains, tawg, cov ces kaum ploj, xim tsis sib xws, thiab cov qauv tsis tiav. Hais txog qhov ntev ntev, lub thickness yuav tsum yog qhov kev ncua deb ntawm sab xub ntiag thiab sab nraub qaum ntawm lub rooj tsavxwm, tsis suav nrog cov npoo chamfered, qhov, thiab cov qauv embossed.
Raws li lub teb chaws cov qauv kev tiv thaiv ib puag ncig, qib xov tooj cua ntawm cov ntaub ntawv qab nthab tau muab faib ua peb pawg (feem ntau yog siv tau rau cov khoom tsis yog-hlau, tsis yog- cov ntaub ntawv hauv qab nthab, xws li gypsum board).
