KOMIYA C Purlin are produced from quality imported high tensile galvanised steel, which design to meet all international standard. The design of cut to length, various hole punching process and zinc coated surface provide the convenience of immediate erection upon delivery without any fabrication and painting work at site. With the additional of reinforcement ribs it will further enhance the resistance of purlin strength when the load was applied on top.
