Quality Pre-Galvanised Steel Offers Protection Against Corrosion

Galvanising is a highly effective and economical way of protecting a variety of steel articles, both industrial and commercial, from corrosion.  In this process, zinc is deposited onto a steel surface, which creates a layer to protect against corrosion of the steel base that is being coated. Before this zinc deposition, the steel sheets are cleaned with sulphuric acid and fluxed with ammonium chloride.  Pre-galvanised steel is a process where steel is galvanised as a sheet, before it is formed into a product and not after the product is created.

Pre-galvanised steel fulfils several commercial and industrial needs.  This can be anything from galvanised roofing, siding roofing nails and other fasteners, beams, sidings, utility poles, fencing and a whole lot of general agricultural and industrial components.

Use of pre-galvanised steel is not a new happening, as this process dates back to the mid 19^th century, but it has come to become important in construction ever since the 1950s.  However, initially, these steel sheets used to be passed through a coating pot, and dipped into molten zinc by hand.  But with the huge advances in technology, easier and more efficient techniques are being used today, to facilitate mass production of high-quality pre-galvanised steel.

There is an outstanding history of using pre-galvanised steel for protection from damage caused by atmospheric, soil and water environments. Decades of using steel products created through this process shows us that the pre-galvanisation treatment is a very effective means of preventing damage.

There are many reasons it is found to be desirable in construction:

• Provides corrosion resistance
• Prevents coating degradation
• Helps with colour retention
• Offers better formability
• Costs less

Pre-galvanised steel is used by construction companies as panels in roofing and siding.  It is used in utility poles in the electricity lines and also as automobile body panels.  In fact, this form of steel can be used by any application that needs galvanic protection because of mechanical damage.

Today, pre-galvanised materials are considered to be the industry benchmark. Everyone from contractors to engineers to architects use this form of steel to design a variety of structures; including buildings, parking lots, sports stadiums, shopping malls, parks and everything else that uses steel.

There are many manufacturers of pre-galvanised steel in the market, but using one that gives importance to quality-control goes a long way in ensuring the structures you create using this steel last long and do what they are supposed to – protect from damage.  Everything from the aluminium content to the quality of the galvanising zinc bath makes a difference on the appearance, thickness and protection from rust formation of the steel sheets.  Good companies ensure they follow international standards.
