The newly innovated hidden tapping nail design by Strong House is really simple to construct. After locking in the tapping nail, press on the bonding point of the two sheets and the bonding is completed.
The traditional nail construction usually get loose after exposed to the weather and cause water leakage, while the newly designed hidden tapping nail construction won’t have this problem.
We use plug-in convergence in between the roofing sheets, in order to prevent leakage during strong storms. In addition, there’s enough space to insert 25m/m of iron chip to add on to the tapping nails to gain addition stiffness for the roofing sheets to stand against strong winds.
The flat-bottom design of the roofing sheet not only prevents gaps in between but also good looking.
