Nws raug pom zoo kom sivcov vuas asphaltHauv cov tsev nyob siab heev. Lub zeem muag ntawm pem teb siab yog txwv thiab tsis cuam tshuam rau qib kev zoo nkauj. Cov vuas asphalt yog cov vuas yooj ywm, tom qab lub sijhawm ntev ntawm kev laus tsis yooj yim poob txaus ntshai. Cov tsev nyob siab, villas, tsev so, tsev qhua, cov haujlwm pej xeem thiab lwm lub tsev siab tuaj yeem siv cov vuas hlau pob zeb xim, txhim kho kev zoo nkauj thiab lub neej ntev, tsis tas yuav saib xyuas tom qab.

Ximpob zeb hlau pobzebthiab cov vuas resin, cov vuas asphalt piv rau, cov vuas pob zeb xim hlau muaj lub neej ua haujlwm txog li 50 xyoo, tuaj yeem tiv taus ntau yam huab cua hnyav. Tib lub sijhawm, nws yog 100% hluav taws kub retardant, uas tuaj yeem txo qhov kev puas tsuaj los ntawm hluav taws.

Cov vuas pob zeb xim hlau yog muab xuab zeb sintered sib npaug zos rau ntawm lub phaj hlau aluminized zinc, ib qho yog los tiv thaiv cov vuas, qhov thib ob yog ua kom cov vuas zoo nkauj dua, xuab zeb sintered yog forged los ntawm ntuj basalt, basalt yog cov khoom siv raw zoo rau kev tsim cov "pob zeb cam khwb cia". Pob zeb cam khwb cia yog basalt tom qab yaj casting, crystallization kho, annealing khoom. Nws muaj zog dua thiab hnav-resistant dua li hlau alloy, thiab tiv taus corrosion dua li txhuas thiab roj hmab. Basalt muaj kev ua tau zoo heev compressive thiab flexural, zoo hnav-resistant thiab tsawg dej nqus. Nws kuj yog cov khoom siv kho kom zoo nkauj architectural zoo heev thiab tuaj yeem siv dav hauv kev kho kom zoo nkauj sab hauv tsev thiab sab nraum zoov.
