A number of stores manufacture and distribute polycarbonates in the form of panels or sheets.This calls for additional processes more so during installation to achieve various shapes and designs.

For instance,to achieve square shapes,these sheets will be cut and bonded together.

Another common scenario during the installation process is the mechanism needed to secure these PC sheets on the desired structure.

Bonding & Fastening Corrugated Polycarbonate Roofing Panels

There are a number of processes and procedures which are used to bond and fasten corrugated polycarbonate roofing panels.

Some of the most common methods include:

Mechanical fastening


This involves the use of various fastening methods to attach the polycarbonate sheet on the desired material.

Normally,aluminum screws and rivets are used to join corrugated polycarbonate roofing panels using the recommended proper attachment methods.



In this process,two washers are used on both sides of the polycarbonate corrugated  panel to cushion and distribute stress during the fastening process.

In this process,an oversized hole is drilled in the corrugated polycarbonate roofing panel.The hole should be soft and free from any cracks.

This implies that proper drilling mechanisms should be adopted.You need to consider the disparities which may exist between the polycarbonate panels and the washers.

Solvent bonding

Polycarbonate manufacturers and distributors recommend only certain types of bonding solvents.This is for the reason that such solvents have minimal effect on the polycarbonate panels.

It is one of the most popular method which is used to construct 3-D shapes using corrugated polycarbonate roofing panels.

3-D shapes


There two techniques which are commonly used include edge dipping and capillary action technique.

And there are three main procedures which are involved in this processes and they include edge preparation,pressure and curing processes.

It is worth noting that this process may reduce the strength of polycarbonate materials significantly.


For the process to be successful,the edges should be cleaned and free from any dirt,they should be smooth and aligned properly and an even pressure must be applied across the joint to eliminate bubble formation which may result into a weak bond.

One common problem with the solvent bonding technique is surface whitening.Therefore, the process should be carried out in an area with low relative humidity or about 10% glacial acetic acid should be added.

At times,thickening the solvent may reduce the whitening problems.


The transfer tape bonding

At times,when it comes to bonding thin-gauge polycarbonate panels,it is nearly impossible to achieve a strong edge bond.

This makes the use of transfer tapes ideal for the bonding process.At times,this may also require slight design modifications.

It involves a very simple process whereby you will bend a small portion of the part to be bonded.The section should be the size of the transfer tape.

Both the tape and the contact sections should be clean and free from any form dirt.After removing the masking tape,press the sections to be bound together.

Normally,improving the bond strength is imperative in this technique too.You can achieve this by rolling the region using a rubber roller.

Adding a mechanical fastener at both ends of the bond will improve the bond strength significantly of the corrugated polycarbonate roofing panels.

Now it’s your turn,make your own corrugated roofing and make all steps yourself step by step.and if you need polycarbonate panels,just search your local wholesaler,of course if you need over 50 pieces polycarbonate panels,you can get a great price from Excelite,click here to contact Excelite.
