for Floor Deck Sheets
What is hot-dip galvanised steel?
Hot-dip galvanising is a process that involves coating steel with a
thin layer of zinc to prevent rust from forming. The surface
treatment is achieved by passing the steel through molten zinc at
high temperature, providing long-term protection for steel
products.
The zinc coating has a corrosion resistance and sacrificial
corrosion function that delays the production of red rust. The zinc
layer of hot-dip galvanised steel is higher than that of
electro-galvanised sheet steel, giving it better corrosion
resistance.
Steel deck overview
Floor decking sheets is also known as profiled steel deck,metal
deck,roof decking, etc.The earliest name of bondek is called
corrugated steel deck,and all steel floor decking sheets that are
pressed and formed by a platen press and are collectively referred
to.The floor slab is made from galvanized steel sheet by cold roll
forming,and its cross section is V-shaped, U-shaped, trapezoidal or
the like. It is mainly used as a permanent template and can also be
selected for other purposes.The earliest compacted steel decking
sheets were mainly used as roof panels of factory roof,followed by
profiled steel plates used for the floors and gradually classified
as floor decking sheets.
- All steel shall be coated to conform to ASTM A924 G-60 or G-90 or
to Federal Specification QQ-S-775.
- Galvanized finish in G-90 coating is desirable in high moisture
atmospheric conditions.
