FAQ

Q: Dab tsi yog qhov siab tshaj plaws load peev xwm ntawm ib qho hnyav - lub rooj zaum?

A: Txheem hnyav-cov khoom siv yas nqa tau txog li 1,070 kg (2,350 lbs) dynamic point load. Cov hlau xaim hlau nqa mus txog 1,500 kg (3,300 lbs).

Q: Puas yog lub hauv paus dav puncture subgrade vapor barriers?

A: Tsis yog. Heavy- cov rooj zaum slab muaj lub tiaj tiaj, du hauv qab lub hauv paus (120mm + hneev taw) tsim los nthuav tawm qhov hnyav thiab tiv thaiv kev sib tsoo.

Q: Cov rooj zaum no puas haum rau CRSI Chav Kawm 1 qhov kev xav tau ntawm cov pob zeb?

A: Yog. Tag nrho- cov qauv yas HDPE ua tau raws li CRSI Chav Kawm 1 qhov yuav tsum tau ua vim lawv tsis muaj cov hlau ferrous uas tuaj yeem xeb lossis stains cov pob zeb.

Q: Yuav tsum muaj pes tsawg lub rooj zaum ib square meter (los yog square yard)?

A: Feem ntau 1.2 mus rau 1.5 lub rooj zaum ib square meter (kwv yees . 1 lub rooj zaum ib square yard), kho raws li tag nrho cov hnyav steel thiab ncuav ko taw tsheb.

Q: Cov rooj zaum no puas tuaj yeem tiv taus qhov chaw ua haujlwm kub thiab txias?

A: Yog. High-density polypropylene formulas maintain impact strength down to -20℃(-4℃F) and resist UV degradation during open-air storage.

Q: Cov ntawv pov thawj dab tsi yog muab nrog cov khoom xa tuaj?

A: Txhua qhov khoom xa tuaj suav nrog Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (CoA), cov ntaub ntawv qhia txog kev ua raws li cov khoom siv raw, thiab cov ntawv pov thawj muaj peev xwm ua tau raws li ASTM thiab BS cov qauv.
