Raws li peb paub European tus qauv EN 39 qhia txog cov kev cai rau unalloyed carbon steel welded round tubes npaj rau siv nyob rau hauv kev tsim kho ntawm scaffold.

Scaffolding yog ib ntus qauv siv los txhawb tib neeg thiab cov khoom siv hauv kev tsim kho thiab kho vaj tse thiab lwm cov qauv loj. Tubes rau EN39 no European Standard, uas muaj ib tug tshwj xeeb sab nraud txoj kab uas hla ntawm 48.3mm thiab teev phab ntsa thickness ntawm 3.2mm los yog 4.0mm.length yuav ua tau ntau yam.
