Z hlediska n\u00e1klad\u016f je hlin\u00edk levn\u011bj\u0161\u00ed ne\u017e nerezov\u00e1 ocel a je leh\u010d\u00ed na p\u0159epravu.

Hlavn\u00ed v\u00fdhodou je hmotnost. Hlin\u00edk v\u00e1\u017e\u00ed asi t\u0159etinu oceli. D\u00edky tomu se s hlin\u00edkov\u00fdmi teleskopick\u00fdmi trubkami mnohem l\u00e9pe manipuluje a p\u0159epravuje.

Dal\u0161\u00ed v\u00fdhodou je odolnost proti korozi. Hlin\u00edk p\u0159irozen\u011b vytv\u00e1\u0159\u00ed tenkou vrstvu oxidu, kter\u00e1 zabra\u0148uje korozi. To pom\u00e1h\u00e1, kdy\u017e jsou trubky vystaveny pov\u011btrnostn\u00edm vliv\u016fm. Ocel vy\u017eaduje n\u00e1t\u011bry, jako je barva nebo pokoven\u00ed, a n\u00e1t\u011bry se mohou po\u0161kr\u00e1bat nebo opot\u0159ebovat. \u00dadr\u017eba je u oceli \u010dast\u011bj\u0161\u00ed.<\/p>\n

V\u00fdroba a mont\u00e1\u017e je u hlin\u00edku jednodu\u0161\u0161\u00ed. Rychleji se obr\u00e1b\u00ed, snadno vrt\u00e1 a \u0159e\u017ee a rychle sva\u0159uje metodou MIG nebo TIG. Sva\u0159ov\u00e1n\u00ed oceli bez deformace vy\u017eaduje v\u00edce tepla a zru\u010dnosti.<\/p>\n

Dal\u0161\u00ed v\u00fdhodou je recyklace. Hlin\u00edk se snadno recykluje s n\u00edzkou spot\u0159ebou energie. Hotov\u00e9 v\u00fdrobky jsou \u0161etrn\u011bj\u0161\u00ed k \u017eivotn\u00edmu prost\u0159ed\u00ed.
