    Product Raw Materials and Processes<\/h2>\n

    Main Raw Materials<\/h3>\n

    The direct raw material for parallel thread rebars coupler is medium- and large-sized construction steel, characterized by longitudinal and transverse ribs on the surface. It is classified into grades such as HRB335, HRB400, and HRB500, according to yield strength.<\/p>\n

    Manufacturing Processes<\/span><\/span><\/h3>\n
    <\/div>\n
    There are four main processes:<\/span><\/span><\/div>\n
    <\/div>\n
      \n
    1. Forging or Cold Rolling Forming: Steel bars are forged or cold-rolled to produce coupler blanks.<\/span><\/span><\/li>\n
    2. Thread Processing: Internal threads are machined using a thread rolling machine or lathe (to match the rebar end threads).<\/span><\/span><\/li>\n
    3. Heat Treatment (Optional): High-strength couplers undergo quenching and tempering to enhance performance.<\/span><\/span><\/li>\n
    4. Surface Treatment: Anti-rust coating (e.g., galvanization) or oxidation treatment.<\/span><\/span><\/li>\n<\/ol>\n
