ASTM A500 Square Steel Tube rau cov lus piav qhia
ASTM A500 series square thiab rectangular tubing yog tsim raws li tus qauv ASTM A500 thiab feem ntau siv hauv kev tsim vaj tsev. Cov tubing series no muaj lub zog zoo thiab ua haujlwm ntev, ua rau nws yog cov khoom siv nrov hauv ntau yam xws li kev tsim kho, choj tsev, thiab kev tsim khoom siv tshuab. Nws cov ntsiab lus tseem ceeb npog cov square thiab duab plaub qhov ntau thiab tsawg los ntawm me me mus rau qhov loj kom haum rau ntau hom kev tsim qauv.
Main Specifications ntawm A500 Series:
Square thiab Rectangular Tubing Sizes: Feem ntau square tubing qhov ntau thiab tsawg hauv A500 series suav nrog 25x25mm, 50x50mm, 75x75mm, thiab 100x100mm, thaum cov tubing qhov ntau thiab tsawg suav nrog 50x25mm, 100x50mm, thiab 150x75mm. Qhov ntau qhov ntau thiab tsawg no tso cai rau nws ua tau raws li qhov xav tau ntawm cov haujlwm sib txawv.
Phab ntsa Thickness Range: Phab ntsa thickness ntawm square thiab rectangular tubing feem ntau yog li ntawm 2 hli mus rau 16 hli. Qhov kev xaiv ntawm phab ntsa thickness ncaj qha cuam tshuam rau nws cov load- bearing peev thiab nqi.
