Esisinkitty neliö & Suorakaiteen muotoinen teräsputki – Q235B

Q235B square and rectangular tube with pre-galvanized coating for frames, telineet, solar supports and fencing.

Pre-galvanized square and rectangular steel tube is formed from galvanized strip and welded into a closed section, then cut to length. The zinc coating covers the whole surface including corners, and the clean, bright finish makes it ready for use or painting without further treatment — ideal for racks, frames and structural sections.

All-Round Coating

Zinc covers surface and corners uniformly.

Käyttövalmis

Kirkas viimeistely, no pre-treatment required.
