Description
APPLICATIONS
Uses of galvanised hollow sections include structural and construction applications, frames, railings, general fabrication, building supports, furniture, automotive, agricultural and manufacturing.
TYPES
Two of the common grades of galvanised hollow sections are EN10025 S275 and S355. EN10025 S275 is a popular low carbon structural steel grade suitable for various general engineering and construction applications. As a low carbon steel specifications, EN10025 S275 provides high tensile strength with good machinability and can be easily welded at low temperature settings. Galvanised mild steel grade S275 possesses good cold-forming properties and is used widely in the construction, industrial and engineering industries.
Galvanised mild steel grade EN10025 S355 is another widely used low carbon steel, which is suitable for a large number of structural applications. EN10025 S355 usually possesses hot-finished properties has greater mechanical resistance, as well as high yielding strength.
| Types | Description |
|---|---|
| Hot-Dip Galvanising | Application of a zinc coating by dipping steel in a molten pool of zinc. Alloy layers such as zinc oxide and zinc carbonate, are formed on the primary metal through reaction with the surrounding atmosphere to form a protect coating. |
| Electrogalvanising | An electrolyte solution is passed through an electric current, which is later applied to the steel. The electric current reduces positively charged zinc ions to zinc metal, which is then deposited on the positively charged steel. |
| Pre-Galvanising | Rolling sheet metal through a cleaning agent to quickly prime material for galvanising. The metal is passed through a pool of molten liquid zinc and is instantly recoiled. |
| Cold Galvanising | Application of zinc-rich paint to the surface of steel metal to protect it from corrosion. |
COMMON GRADES, SIZES AND SPECIFICATIONS
| Grades | Width | Thickness | Length |
