Lub sij hawm RHS sawv rauRectangular Hollow Section.
SHS sawv rauSquare Hollow Tshooj.
Tsawg tsis paub yog lo lus CHS, qhov no yog rauCircular Hollow Section.
Nyob rau hauv lub ntiaj teb no ntawm engineering thiab kev tsim kho, cov acronym RHS, SHS thiab CHS feem ntau siv. Qhov no feem ntau tshwm sim hauv tebchaws United Kingdom thiab cov tebchaws koom nrog, suav nrog Australia thiab New Zealand.
Cov ntsiab lus no tau siv dav los piav txog cov hlau me me; Txawm li cas los xij, lawv kuj tuaj yeem raug txhais rau stainless hlau thiab txhuas engineering thiab kev tsim kho los ntawm engineers uas paub txog cov ntsiab lus.
Rectangular Hollow Section yog ib lub duab plaub steel profile nrog lub voj voos hollow hla ntu thoob plaws nws qhov ntev, siv ntau yam kev tsim kho thiab engineering tej yaam num. Rectangular Hollow Sections (RHS) kuj hu ua txias tsim hollow seem los yog lub thawv seem.
Youfa muab ntau yam ntawm cov duab plaub hollow seem specifications rau ze li ntawm 100 lub teb chaws thiab cheeb tsam. Youfa hom RHS hollow seem tau ntawv pov thawj nrog ISO 9001, ISO 18001, FPC thiab CE, ua raws li JIS G3466, ASTM A500 thiab EN10219.

Square Hollow Sections (SHS), tseem hu ua txias tsim hollow seem los yog lub thawv seem, yog ib qho ntawm ntau yam khoom siv hauv tsev hauv kev tsim kho. Feem ntau muaj nyob rau hauv 5.8 meter ntev thiab 6 meter ntev hauv Qib A Qib B, S235 S195; Raws li kev txiav txim kom muaj nuj nqis loj, lwm qhov ntev thiab Qib C, S355 lossis lwm qib muaj. Rau koj cov ntaub ntawv Kg / m yog hais txog Kilograms ib Meter ntawm seem, piv txwv li 6.0 Meter ntev ntawm 50 x 50 x 3mm (SHS) Square Steel Hollow Section (4.49 Kg / m) theoretical hnyav yuav yog (6 x 4.49). ) 26.94 Kg Tag Nrho.
Youfa Steel Pipe factories faib thiab tsim cov square hollow seem specifications xws li 20x20mm txog 400x400mm thiab feem ntau xa tawm mus rau Southeast Asia, East Asia, Middle thiab South America, Middle East thiab Africa. Youfa hom SHS hollow seem tau ntawv pov thawj nrog ISO, FPC thiab CE, ua raws li JIS G3466, ASTM A500 thiab EN10219.
