If your fence is made of standard corrugated sheet, then when buying you just need to look carefully at what type of profiled sheet the strip is intended for. If the fence is made of non-standard grades of metal profile (C10, C13, C15), then the profile is selected according to the actual dimensions.

For example,
The U-shaped strip for the C8 profiled sheet can be from 8 to 17 mm wide. In a wide profile, one of the inner sides is made with a triangular drip. The drip bends well, so such a U-profile is suitable not only for the C8 profiled sheet, but also for sheets with a higher wave height.

When choosing a U-profile for non-standard grades of corrugated sheets, take a sample sheet with you to measure and choose the right one. Make sure that the strip does not fit peru mobile database the sheet too tightly - if the pressing force is too great, its edges can damage the protective and decorative coating of the metal profile at the point of contact. This will lead to accelerated corrosion. If the strip is too loose on the sheet, it will not be able to perform any functions other than decorative.

Selecting the type of polymer coating
The finishing strip for a fence made of corrugated sheeting is not galvanized. It is produced only with a protective and decorative polymer coating. As a rule, this is ordinary polyester, but there are strips with a pural or PVDF coating. For fences made of corrugated sheeting with a pattern, cover P-profiles with a Printech coating with the same texture are produced.

The rule for choosing a coating is simple: the thicker it is, the better it protects against corrosion. There is only one exception - plastisol. This is a coating of increased mechanical strength (layer thickness from 200 microns), which is designed to protect steel from the effects of aggressive substances, for example, during installation near chemical plants. But under normal conditions, plastisol shows itself worse than pural.

More specifically, polyester is the least durable coating. Matte polyester protects better, about the same as PVDF. Pural is the best option if the strip on the fence profile sheet is single-color. For a profile with a pattern, choose PVDF, not standard polyester.
