Pre Galvanized Tubes / Fence Tubes / Sendzimir Tubes:
Pre Galvanized Tubes / Fence Tubes / Sendzimir Tubes As the name of the pipe clearly indicates that this kind of steel pipes & tubes are galvanized before hand, in the shape of Coils and then the round shapes are being given at the Tube Mill.
The Pre-Galvanized Tubes / Fence Tubes / Sendzimir Tubes are manufactured by high frequency electric resistance welding method, after removing the outside welding beam then electric painting zinc onto the welding area to antisepticise the surface.
Pre-Galvanized / Fence / Sendzimir Tubes are being introduced and promoted worldwide because of the following reasons:-
- Enhancement of the Galvanized steel Pipes & Tubes application.
- Availability of cheaper version for the customer when Zinc prices are at its peak.
- Right product for right application and not common product for all kind of applications.
- Availability of non-standard thickness in galvanized form.
Our range of (Pre-Galvanized Tubes or Fence Tubes or Sendzimir Tubes) is available in a variety of dimensions and can also be customized as per the client's requirement.
Diversified form of steel has yet to come for the world which will change the face of all the economies with easy applicability, adaptability, affordability, viability & stability.
