Introduction GW-40A steel bar bending testing machines are special equipment which process cold bend tests and plane re-bend tests. It is the ideal testing equipment which is used for testing bend or re-bend performance of steel bars for Steel industries and Building Units. steel tube bending testing equipment/steel pipe flexural testing device Standard: 1.GB1499.2-2007 <The second part of Steel tube for the reinforcement of concrete: hot rolled ribbed steel bars>, 2.YB/T5126-2003 <Program of steel bars plane re-bend tests> 3.ISO10065:1900 cold bend tests and plane re-bend tests.
