3,Pre-punching service of Z steel frame:

In order to make construction on-site faster and easier,steel Z purlins could be pre-punched in our factory.
There is two kinds of holes we have,as per Chinese GB standards,round holes and elongated holes,which is as per the following picture showing:




Holes are made during production at continuous line,some additional notes are showing as follows:

• Holes can be made in a row or positions as per your design;
• Oval and rectangular holes can be rotated by 90°;
• Please contact us for additional information about the pre-punching possibilities,if you have any special hole punching requirement about hole size and hole shapes.

4,Production process:

1)Material preparation:Usually our steel material standards of Z purlin is Chinese standards Q195/235/345,we could also make as per your steel standards;
2)Hole pre-punched:If you have hole punching requirement,we could exactly punch the holes as per your requirements;
3)Cutting:Length could be any customized size,but it will be limited by container size,it's max 5.8meters for 20FT container and 11.8meters for 40FT container;
4)Quality inspection:We have QC people in workshop to do quality inspection,to ensure the product quality for customers.



5,Product application:

C Purlin: 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.

Z Purlin: Purlin and wall beam of steel structure building The Z-shaped purlins have excellent anti-bending property and are easy to install. They are widely used as the supporter of roof and wall in large-scale and MID-scale construction, such as factory, warehouse, garage, exhibition center, cinema, theatre, garden and so on.
