Cold Roll Forming development characteristics

Cold Roll Forming development characteristics (Cold-formed steel machines) produced cold-formed steel products has evolved to a special shaped thin-walled, light direction, especially for large cross-section, thick-walled steel and thin-walled section of a small complex product also expanding trend. Cold-formed steel products abroad has grown to 10,000 kinds of specifications and varieties. Construction industry, with large thick-walled square, rectangular and round pipe, the amount is increasing. Curved sheet pile roll forming machine as abroad have 700X700X32 mm square hollow steel, used in the manufacture of large structural parts, a good cross-section properties, not only to facilitate the construction, but also reduces the consumption of steel, and if the (cold roll forming machine) is in civil engineering, better impact resistance, economy and due to the locking structure brings high security in the market with strong competitiveness.
