Birta ilaalada xawaaraha sare leh waxay nuugtaa tamarta isku dhaca iyadoo adeegsanaysa isbeddelka aasaaska ciidda, tiirarka iyo alwaaxa, waxayna ku qasabtaa gawaarida cararaya inay beddelaan jihada oo ay ku soo noqdaan jihada wadista caadiga ah, taasoo ka hortagaysa baabuurta inay ka cararaan wadada, ilaalinta baabuurta iyo rakaabka iyo yareynta khasaaraha ka dhasha shilalka.

Biraha ilaalada ee xawaaraha sare leh ee W beam galvanized ayaa si caadi ah loogu isticmaalaa mashaariicda Guardrails-ka Waddooyinka. Biraha ilaalada ee xawaaraha sare leh wuxuu nuugaa tamarta isku dhaca isagoo adeegsanaya isbeddelka aasaaska ciidda, tiirka iyo biraha, wuxuuna ku qasbaa gawaarida baxsadka ah inay beddelaan jihada oo ay ku noqdaan jihada wadista caadiga ah, taasoo ka hortagaysa gawaarida inay ka cararaan wadada, ilaalinta gawaarida iyo rakaabka iyo yareynta khasaaraha ka dhasha shilalka.
