PC Sheets Storage:
Stored on flat surfaces or wooden bearers with 100mm minimum bearing surface, placed at centre not exceeding 1m.
Make sure the place where you stored is dry, shaded and well ventilated area.
Use an opaque cover (not under flexible PVC coverings), tightly secured, protecting from wind, rain and sun.
Don't store under direct sunlight or without shelter from rain. Indoors torage is always preferable.

PC Sheets Installation:

Step 1: Use screws to attach the base connecting profiles to the roof beams. Make sure the screws not                 bend, tear or exert excessive pressure on the profile.

Step 2: Place the sheet on top of the base profile support edges, with the side covered by the printed                   protective film facing upwards.
 
Step 3: Slide the base under the sheet and attach it to the beam.

Step 4: Place the side spacer profile onto the roof beam and attach the cap to the base by hammering                 into place with a rubber mallet.

Kindly Remark:

1. As expandable, the drilling diameter must be 1.5 times than that of the bolt.

2. Do not use gaskets made of PVC.

3. PC Sheets can't be installed too tight because there will be thermal expansion and contraction which will adversely affect the installation.
