Unsaturated polyester resin, Continuous Non-alkali fiberglass, non-alkali fiberglass chopped stitch mat and processing aids as main raw material, adopts advanced technology and machines, and produced out under the condition of high pressure and high temperature.
The reasonable design, effectively solve the remained internal corrosion problems of steel purlins and plastic covered steel purlins (PVC dip or plastic spraying), which surface layers are broken and fall off during transportation and installation, also highly meet purlin intensity requirements of light steel structures.
JULI Anticorrosive Polyester Purlin has advantages of excellent corrosion resistance, high strength, easy installation, maintenance free, etc

Futures:
Using FRP material for construction purlins is a valuable innovation.
1. The axial strength of JULI polyester purlins has been up to 290Mpa,reach to steels’ strength.
2. Being with high strength, excellent anti-corrosion and anti-aging performance, there is no any other material can instead of its high cost-efficient at present.
Color steel sheets and metal purlins have been corroded heavily after using one year. Replaced by JULI Polyester fiber corrugated sheets and anti-corrosion purlins after one year, excellent without corrosion.

Purlin Installation:
Not allowed to put excess sheets or other debris on anti-corrosion purlins, not exceed two workers to step on each purlin.
Purlins located directly on steel beam and no gap between them.
Before installing bolts, firstly mount special supporting end cap at the end of anti-corrosion purlins,
When install bolts, keeping nuts and eaves pallet on the same side. Fix bolts appropriately to not damage the shape of anti-corrosion purlins.
For model220 anti-corrosion purlin, beam space ≦8000MM, Purlin Space≦1500MM, design purlin space according to loading requirements of anti-corrosion purlins’.
