CRB800CRB650CRB550三种钢筋有什么区别？价格有什么不同？

 CRB650CRB800和CRB550在性能和价格方面是有本质区别的。

CRB650是预应力钢筋 规格为：5mm和6mm两种，抗拉强度为：不小于650MPA，屈服不小于585MPA ，延伸不小于4%  冷弯三项无裂纹。多用于预应力混凝土中。

CRB800是预应力钢筋 规格为：5mm和6mm两种，抗拉强度为：大于等于800MAP，屈服大于等于720MPA，延伸大于等于4%，冷弯三项无裂纹。多用于预应力混凝土中。

CRB550为冷轧带肋钢筋  规格为：4mm-12mm 抗拉强度不小于550MPA，屈服不小于500MPA,延伸不小于11%，冷弯三项无裂纹。多用于普通混凝土。

从上面可以看出，CRB650预应力钢筋、CRB800预应力钢筋、CRB550冷轧带肋钢筋，在抗拉强度和延伸以及用途方面有所不同。但外观均为螺纹钢筋，多为盘状销售。价格方面  CRB550价格低于CRB650低于CRB800。所以强度越来，价格越高。我公司除了以上3种钢筋外，还有CRB550钢筋网、CPB550光圆钢筋网、YB/T 5294一般用途低碳钢丝、GFW平纹斜纹不锈钢编织网、不锈钢防鸟网、不锈钢防蚊防虫网、PVC护栏网、不锈钢过滤片、滤网、滤帽等。 LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&lmt=1692412480&plat=8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C41%3A32%2C42%3A32&plas=250x581_l%7C250x581_r&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&pra=5&wgl=1&uach=WyJXaW5kb3dzIiwiMC4xLjAiLCJ4ODYiLCIiLCIxNC4xLjEyMDUuMCIsW10SMCxudWxsLCI2NCIsW1siTm90LUEuQnJhbmQiLCIyNC4wLjAuMCJdLFsiQ2hyb21pdW0iLCIxNC4xLjEyMDUuMCJdXSwxXQ..&dt=1692412479834&bpp=7&bdt=19&idt=148&shv=r20230816&mjsv=m202308140101&ptt=9&saldr=aa&cookie=ID%3Debc4286d1804de59-22e6d5e6eee20009%3AT%3D1692410716%3ART%3D1692412233%3AS%3DALNI_MbR9Sphl0OJtsZMk1rxEVb7jGJi5A&gpic=UID%3D00000c2ef95847f7%3AT%3D1692410716%3ART%3D1692412233%3AS%3DALNI_MZNphrsDGD-pDJLZy-Bu_C7xakEBg&nras=1&correlator=8649087168404&frm=23&ife=1&pv=2&ga_vid=225695561.1692412480&ga_sid=1692412480&ga_hid=564307879&ga_fc=0&nhd=1&u_tz=480&u_his=17&u_h=1080&u_w=1920&u_ah=1032&u_aw=1920&u_cd=24&u_sd=1.25&DMC=4&adx=-12245933&ady=-12245933&biw=1514&bih=742&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44759837%2C44759875%2C44759926%2C31076839%2C31077087%2C31077148%2C44798934%2C44799579%2C21065725&oid=2&pvsid=3283413367749105&tmod=676985861&uas=0&nvt=1&fsapi=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1032%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.axo9ma8rsnv3&fsb=1&dtd=189" data-google-container-id="1.axo9ma8rsnv3" data-load-complete="true">
