Galvanized square tube & rectangular tube

Kev Piav Qhia Luv:

Cov yeeb nkab galvanized rectangular yog ib lo lus rau cov yeeb nkab plaub fab thiab cov yeeb nkab plaub fab, uas yog, cov yeeb nkab hlau uas muaj qhov ntev sib npaug. Nws yog ua los ntawm kev dov cov hlau tom qab kev kho mob. Feem ntau, cov hlau strip yog unpacked, flattened, crimped, thiab welded los ua ib lub raj puag ncig, tom qab ntawd lub raj puag ncig raug dov ua ib lub raj plaub fab thiab tom qab ntawd txiav mus rau qhov ntev uas xav tau. Feem ntau 50 daim ib pob. Kuj tseem hu ua square thiab rectangular cold-formed hollow section steel, luv ua square tube thiab rectangular tube, cov lej yog F thiab J feem.
