C purlin production process has three stages,material preparation and equipment preparation and processing.
Material preparation:The related specs of GI steel strips will be prepared and loaded on equipment;
Equipment preparation:Our workshop manager will check and adjust the equipment to make sure the C steel purlin equipment is in correct status for production;
Processing:This is including holes pre-punching,cold rolled,cutting as per required length,and stack in proper position and well protected,then finally quality inspection by our QC people.
Product applications:
It is used widely as purlin and wall beam on steel structure construction.Also it can be combined into a light weight roof truss,brackets,etc.In machinery light manufacturing,C purlin can also be made into Column,beam or arm limb,etc.
