Fence concept: The connection way for the mesh panel and upright post are called fence mesh, such as the connection of mesh panel and upright post, the connection for the frame and upright post. The following main introduction are the control process of upright post and frame mesh panel.
(1) Upright post production process( Round pipe, square pipe and rectangular tube: Pipe wall thickness and diameter measurement- blanking and cutting ( Or cutting angle) - Mould production and confirmation ¨CWeld side ear for upright post welding ( Or punch a hole) - Bend or weld the upright post- Inspector make a inspection ¨C Make surface treatment for the mesh panel according to the customer¡¯s needs.

(2). Quality control process for the frame fence
Production process for the frame fence: Purchase needed pipe and inspect the wall thickness, length and weight ¨C blanking and cutting - Mould production and confirmation ¨C Weld frame and self inspection ¨C Weld the frame and mesh panel ¨C First set of net frame and upright post structure installation and inspection - Process inspection - Count finished products and spot check ¨C Be put into storage and convert into next process
