Tilmaamaha ASTM A871 waa qeexitaanka caadiga ah ee taarikada qaab dhismeedka hoose ee aluminiumka ah ee xoogga sare leh oo leh iska caabbinta daxalka hawada ee loo isticmaalo dhismayaasha tubular iyo tiirarka. Fasalada 60 iyo 65 waxaa lagu heli karaa sida-duuban, caadiga ah, ama la demiyay iyo xaaladaha dhalista sida loo baahan yahay si loo gaaro sifooyinka farsamo ee cayiman.

Tilmaamaha:
Dhumucda: 3mm--150mm
Ballaca: 30mm--4000mm
Dhererka: 1000mm--12000mm
Heerka: ASTM EN10025 JIS GB
