There has been a drastic change in the nail-making industry of China. The nail-making factories quantity are shrinking very fast in the past ten years.
A lot of the roofing nail factories have been closed due to fierce competition among manufacturers and traders.
We have found that Weifang city of China has the most umbrella head roofing nail factories. Weifang has had a long history of making iron nails since the establishment of PRC China. It is the main origin of Chinese-made iron nails including umbrella head roofing nails.
Umbrella Head Roofing Nails Use
This type of nail is a typical kind of fastener used in tropical countries. Umbrella nails are most popular in Nigeria and the Philippines.

F17 formply is structural formwork plywood used in Australia. The term is exclusively used in Australia and New Zealand. Other countries use different terms such film faced plywood, marineplex, marine plywood and plyform.
F17 Stress Grade
F17 is a stress grade of the structural plywood. If plywood is called F17 grade, it has to pass certain tests according to AS 6669 or AS/NZS 2269 standards. Both standards are structural. What does structural mean? It means the plywood can bear heavy loads and can last a long time in the building structure. Even though formwork plywood is a temporary structure, the Australian building industry still requires formply to be structural. Non-structural plywood is shipped to Australia too but it can not be used in governmental projects.
Besides F17, there are other stress grade such as F14, F11, F22, F27, F8, etc. They are graded based upon the bending strength of the ply panels.
