Product Description
Screw hole sealing anti-corrosion: Expand the screw hole to be of 0.8mm through the screw reaming wing,
so that the sealing plastic is evenly squeezed around the screw hole, and the exposed metal plate section is
sealed to achieve the anti-corrosion effect and extend the service life of the plate.
Prevent screw hole leakage: the 23mm diameter sealing waterproof gasket is made of high weather-resistant
plastic material, which has a larger and tighter contact area with the corrugated plate. Under normal installation conditions,
there is absolutely no leakage at the position of the screw hole.
plastic material, which has a larger and tighter contact area with the corrugated plate. Under normal installation conditions,
there is absolutely no leakage at the position of the screw hole.
Improve wind resistance: The diameter of the screw cap is 25mm, which is 13mm larger than the ordinary self-tapping screw,
and the effective protection area of the corrugated plate is increased by 108%. Taking 3 sets of screws per square meter as an example,
the wind resistance performance is increased by more than 3 times.

Screw anti-corrosion: Anti-corrosion coating is adopted, which has 7-10 times the corrosion resistance effect of ordinary galvanized
screws and paint-coated screws.
