巴中螺紋鋼種類那么多,幾點教你辨別劣質螺紋鋼!

建筑工程中少不了鋼材的影子,選購螺紋鋼需注意,巴中螺紋鋼質量的好壞直接影響著建筑的使用壽命,遠離劣質螺紋鋼,在購買螺紋鋼的過程中,應從以下幾點辨別劣質螺紋鋼:

巴中螺紋鋼

首先要從鋼材表面來判斷,可用游標卡量具簡單測量實際尺寸是否比標明尺寸(一般螺紋鋼上均軋有規格標志)小約一個規格左右或更多(如?12螺紋鋼標準內徑為 11.5±0.4mm,而偽劣螺紋鋼內徑大多為10mm左右)。同時有些偽劣螺紋鋼通過軋扁的方式來欺騙人的視覺,因而從鋼筋端面觀察其為扁橢圓形,而正規材端面應基本為圓形。

其二:從表面質量看,偽劣螺紋鋼由于用土坯軋制,其表面質量差,常帶有結疤等缺陷,有整體粗糙感。同時有些小軋廠由于加熱溫度、軋制速度不夠,表面顏色偏紅。

其三:正規鋼材在廠家出廠時大多大捆包裝,成捆鋼材上均掛有與實物相對應的金屬標牌,標明廠家、鋼材牌號、批號、規格及檢驗代號等。而偽劣鋼筋由于生產條件簡陋,無大型吊裝設備,大多小捆(十根左右捆扎)包裝或散裝,無金屬標牌、無質量保證書。)

以上就是關于巴中螺紋鋼的內容,感謝您的耐心觀看,歡迎咨詢我司電話。
