C channel is made of galvanized steel strips by the method of cold-bending
formed.The surface treatment are galvanized or bare. It has many advantages compared
with traditional structural steel, such as light weight, excellent
performance cross-section, high-strength and so on.
Advantages
Ability to span length
Purlin erection is easier than others
Fast to erect and easy handling
No side drilling/cutting required
Assured dimensions and straightness
High durability, versatility and uniform quality
Low transportation cost due to decreased weight

C purlins processing
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.
